Lotus Evora Carbon Concept, 2010

Lotus Evora Carbon Concept, 2010

 

The Lotus Evora Carbon Concept car emphasises Lotus' motorsport pedigree, utilising beautiful high quality materials with exposed carbon fibre and plush alcantara. The striking white concept car is finished in an advanced water based pearlesent paint that contrasts with the exquisitely finished weave on the carbon fibre panels.

The head turning looks of the Lotus Evora Carbon Concept car provide a more purposeful, planted stance with the car looking lower and more aggressive. This styling direction is continued with a structural carbon fibre roof, Lotus Motorsport influenced carbon diffuser and carbon splitter. The Lotus Evora Carbon Concept car retains the same class leading handling and high tech aluminium bonded and extruded chassis of the production car.

The contemporary interior of the Lotus Evora Carbon Concept car combines the lustre of the carbon panels with perforated leather and matt alcantara. The bespoke interior uses swathes of sumptuous grey alcantara to cover the footwell, dashboard and roof. The soft texture of the leather and alcantara are juxtaposed with the hard surfaces of the carbon fibre to provide a satisfying sensory experience.

The Lotus Evora Carbon Concept car has diamond cut forged 19" alloy wheels front and rear, shod with Pirelli P-Zero Corsa tyres (235/35 wide front and 285/30 wide rear). The wheels and tyres give the Lotus Evora real presence filling the wheel arches and giving the car a purposeful appearance.

Lotus Evora 414E Hybrid Concept, 2010

Lotus Evora 414E Hybrid Concept, 2010

 

The Lotus Evora 414E Hybrid Concept, so-named because this latest environmentally-focused technology demonstrator from Lotus Engineering produces 414 PS (306 kW) of power, promises breathtaking performance from a highly efficient propulsion system. The concept showcases new developments in plug-in, range-extended electric propulsion, new electronic technologies to enhance driver involvement, the adaptability of the Lotus Versatile Vehicle Architecture (VVA) that underpins the Lotus Evora 414E Hybrid and a dramatic new roof system and interior concept from Lotus Design. Through all of these aspects it ultimately demonstrates the exceptional ability of Lotus Engineering to integrate and develop advanced technologies for exciting, efficient, high performance niche vehicles.

The range extended electric drive of the Lotus Evora 414E Hybrid consists of two electric motors driving each of the rear wheels independently via single speed geartrain, integrated into a common transmission housing, thus enabling torque vectoring for stability control of the vehicle. Electrical power is stored in a lithium polymer battery pack optimised for energy density, efficiency and high power demand, mounted in the centre of the vehicle for stability and safety. Additional range is provided by the Lotus Range Extender engine, an optimised 1.2 litre, three-cylinder engine, designed specifically for series hybrid vehicles. The drivetrain is designed to combine astonishing performance with efficient, low emissions driving.

The Lotus Evora 414E Hybrid has been designed to highlight Lotus' innovative electric and hybrid vehicle technology without distracting from the pure sportscar character of the Evora. The solution is innovative, instantly recognizable, beautiful and sporty. It demonstrates Lotus DNA.

The Drivetrain
For the Lotus Evora 414E Hybrid Concept, Lotus Engineering has developed a highly efficient, high performance drivetrain system consisting of twin motors each limited to providing 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque to each wheel via independent, single speed, reduction transmissions integrated into a single housing, enabling torque vectoring dynamic control of the vehicle.

The Lotus Range Extender engine provides 35 kW (48 PS/47 hp) of power at 3,500 rpm via the integrated electrical generator and features an innovative architecture comprising an aluminium monoblock construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. This results in reduced engine mass, assembly costs, package size and improved emissions and engine durability. The engine uses an optimised two-valve, port-fuel injection combustion system to reduce cost and mass and can be operated on alcohol-based fuels and/or gasoline. The generator converts mechanical energy to electrical energy to replenish the battery pack charge and provides additional vehicle range in a small light weight package. The generator is also used as a motor to start the range extender engine. The low mass of the range extender unit (85 kg) and compact package makes it ideal for the series hybrid drivetrain in the Lotus Evora 414E Hybird.

All the operation and management of the range extender engine, the power management of the batteries and motor control are controlled by Lotus' electronic control units and software systems. Full energy management of all the operating systems is the key to maximising performance and operation while minimising energy consumption and CO2 emissions.

For everyday commuting journeys, up to 35 miles can be travelled using battery power. The battery can be charged overnight using a conventional domestic mains supply through a socket concealed by the rear number plate. This permits the vehicle to operate with zero tailpipe emissions. For longer journeys, exceeding the battery capacity, the highly efficient range extender engine is used as a generator to supply the motor with electrical power and top up the battery.

Lotus has used its own vehicle simulation tools to determine the size, capacity, power and performance of all the components in the drivetrain system to optimise the system operation. Overall this is far more energy efficient, weight efficient and cost effective than fitting the vehicle with a larger and more expensive battery, which for the majority of short journeys is a redundant weight, which increases energy requirements. With regard to the total lifetime CO2 emissions of the vehicle, including the energy required to manufacture and run it, the range extender solution has a lower overall CO2 footprint than a fully electric car of comparable performance and operating range running with a larger battery.

The Package
The Lotus Evora 414E Hybrid Concept structure is the same award-winning, versatile vehicle architecture used on the Lotus Evora. The low volume architecture was designed with the upmost flexibility in mind. The Lotus Evora 414E Hybrid is a perfect example of how to integrate a compact packaged drivetrain, with excellent performance and range, while using this underpinning. The complete chassis has remained unchanged from the Evora which maintains the structural integrity and strength performance of the original car.

The structure progresses the Lotus 'bonded and riveted' technology with new and unique extrusions and folded panels, whilst providing production build modularity and lower cost repairs. The chassis has been designed for scalability so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness vastly increases the number of vehicles that can be developed from this vehicle architecture.

Driving Dynamics
The Lotus Evora 414E Hybrid offers exhilarating, all-round dynamic performance and takes advantage of Lotus developed torque vectoring dynamics. Torque vectoring, which is the capacity to generate different torques at each of the driving wheels, is particularly suited to electric vehicles and significantly reduces the conflict between stability and response.

A key benefit of separate motors to drive each rear wheel individually is that this facilitates a much higher level of vehicle dynamics control. Driving the wheels with different levels of torque can not only generate all the capabilities of a conventional ESP system using energy regeneration as opposed to brake application, but it can also actively drive each wheel forward at different rates, producing a turning moment at the rear of the vehicle in addition to the steering input.

This can be used to enhance low speed manoeuvrability and ease of parking but can also be used to produce a much greater level of straight line high speed stability. Incorporating lateral sensors the system also provides stability control capabilities and levels of steering response normally only associated with heavy and expensive rear steer systems. This can provide automatic correction of both understeer and oversteer characteristics. In addition, the standard method to provide high speed stability of designing the rear wheels to toe-in is not required as the torque vectoring system automatically provides this stability control, with toe-in increasing rolling resistance, lowering fuel economy and increasing tyre wear. Lotus' long history of active suspension control provides the core capability to develop this technology and provides extraordinary driving pleasure on the Lotus Evora 414E Hybrid.

Driver Interaction
The Lotus Evora 414E Hybrid Concept provides less of a psychological step change for people familiar with high performance cars compared to other electric and hybrid sports cars. The car has a simulated paddle shift gear change offering ultra quick gear changes reminiscent of a dual clutch transmission, while actually single speed. This enhances the driver interaction with the vehicle and provides a driving experience similar to current internal combustion engine high performance sports cars. The Lotus Evora 414E Hybrid uses a column mounted paddle shift to simulate the gear change and a synthesised engine sound changes frequency with virtual gear selection. The drive torque is also modulated to simulate a physical feeling of a gearshift jolt.

The Lotus Evora 414E Hybrid Concept uses the Lotus Engineering and Harman International developed HALOsonic suite of noise solutions. The first of which is Electronic Sound Synthesis. This generates engine sounds inside the vehicle through the audio system where it provides an exciting sports sound in line with the brand and nature of the vehicle together with a high level of driver feedback in an intuitive manner. In addition, it also generates sound on the outside of the vehicle through speakers mounted at the front and rear to provide a warning to increase pedestrian safety, which is especially important for electric and hybrid vehicles which can be difficult to hear at slower speeds.

There are four driver selectable engine sounds currently on the vehicle, two of which have been designed to have characteristics of a multi-cylinder conventional V6 and V12 engine. There is also a futuristic sound and a combination of a conventional engine and a futuristic sound, enhancing the brand identity of the vehicle as a step forward in electric vehicle design.

The Design
The distinctive colour scheme and 'floating' roof have been carefully designed to accent the cars electric vehicle technology whilst complementing the iconic lines of the Evora.

The signature copper theme is consistently carried throughout the car from the dramatic seat stripes and instrument panel inserts to the copper callipers that nestle behind the carbon grey forged wheels. Inside the cabin a sense of quality and richness has been created by carefully juxtaposing the different tactile qualities intrinsic to leather, Alcantara and metal.

Lotus Evora, 2010

Lotus Evora, 2010


  
 The first all-new Lotus since the iconic Lotus Elise made its debut in 1995, The Lotus Evora enters the sports car market as currently the world's only mid-engined 2+2. Powered by a Lotus-tuned 3.5-litre V6 engine producing 280 PS, and weighing just 1350 kg (prototype specification), the Lotus Evora promises breathtaking performance. During preliminary testing around the famous Nürburgring, the Lotus chassis engineers report that it is extremely agile and great fun to drive - even when clad with the full development disguise that hid the beautiful lines from the prying motor-industry paparazzi.

In addition to its excellent performance and exemplary handling, the Lotus Evora offers a more refined ownership experience than Lotus's existing smaller four-cylinder models. Its elegantly styled cabin is elegantly trimmed and its equipment list includes contemporary features such as an advanced touch-screen multi-media system and electric power-fold door mirrors.

THE LOTUS EVORA IN DETAIL
The Style or function? Have both... Designed 'in-house' by Lotus Design, the sleek and athletic form uses fluid forms and crisp surfaces to communicate velocity, agility and sophistication. Low and wide with modern cab forward proportions, muscular rear haunches and function optimised hip air intakes this is clearly a serious mid engined sportscar that skilfully hides the practicality of its two plus two capability.
Ingress and egress, for example, dictated a minimal "step-over" to get into the Lotus Evora. We simply cut away the surface under the door and created a unique and dramatic piece of sculpture that enhances the stance of the car as well as its useability.

Elsewhere, aerodynamic considerations for drag, down force and cooling had significant but positive influence on the overall form and details such as air intakes. A desire to create balanced down force, that increases cornering performance, led to the adoption of, the now, "signature" top exit radiator vent, race car inspired diffuser and "floating rear wing". Drag limitation, drove the dramatic tear-dropped cabin layout and the curvaceous plan view has given the car a more muscular rear shoulder and conveys a level of sophistication appropriate to this market segment.
This inherent understanding of the relationship between the technical and the aesthetic paid dividends the first time a full-scale model of the Lotus Evora was wind-tunnel tested - only minimal adjustments were required to the car's aerodynamic package to meet the targets for downforce and stability.
The view from the rear three-quarters is just as striking and the one that many will become familiar with as the car passes them on the road. The tapered cabin, diffuser, floating wing, centrally mounted twin tailpipes and distinctive engine bay vents all combine to create a completely unique look.

The design language of the interior reflects that of the exterior - simple, fluid surfaces, soft forms and crisp feature lines wrap around the cabin cosseting the occupants. Unlike recent Lotus products that use a race car inspired, technical minimalism, the Lotus Evora employs a softer approach that utilises premium quality materials and finishes to create a contemporary but luxurious ambience that is unique to Lotus products.
Focused courtesy lighting is used throughout the interior, giving a spectacular illuminated feel to the sculpture design feature of the cabin.

Easy in, easy out
With the Elise and its derivatives, the no-compromise character of the car makes getting in and out across a wide sill and through a comparatively narrow door/window aperture part of the charm of ownership. For the Lotus Evora and its remit for the serious daily driver, and to attract newcomers to the Lotus brand, greater convenience and practicality is provided.
As a consequence the sill is now lower and slimmer (80mm wide compared with 100mm in the Elise), and the whole door aperture taller. The doors open wider than on the Elise and its siblings, while the height of the front seat is raised by 65mm.
But while the Lotus Evora is undeniably more 'lifestyle' in respect of its everyday practicality, once you're seated behind its flat-bottomed steering wheel, it feels every bit as exotic and sporting as you would expect a Lotus to be.

The chassis: Production Low Volume Versatile Vehicle Architecture
The Lotus Evora's chassis is an evolution of the Versatile Vehicle Architecture (VVA) from the Lotus APX concept vehicle previously showcased at the Geneva Motorshow, and allows for the development of a range of vehicles up to a gross vehicle weight of 1,900 kg. This architecture has been designed to be more applicable to mid-volume applications by utilising our low capital investment manufacturing processes. The Lotus Evora structure progresses the Lotus 'bonded and riveted' technology used in the Elise family of vehicles with unique extrusions and folded panels, whilst providing contemporary ease of ingress/egress, build modularity and improved, lower cost repairs.

The Low Volume VVA architecture has been designed so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness, vastly increases the number of vehicles that can be developed from this vehicle architecture. Front and mid engine installations have been considered, as well as hybrid and Electric Vehicle (EV) applications.
The Lotus Evora employs a composite roof as a stressed structural member to give an exceptional vehicle stiffness of 26,000 Nm per degree, thanks in part to the seatbelt anchorage frame's secondary function as a roll over structure, and partly because the high-tech composite body panels are stressed items. However, despite this high stiffness, the complete chassis and modules weight just 200 kg (prototype weight), helping to keep the weight of the whole car to just 1350 kg (prototype weight).

The Suspended & animated
The Lotus Evora suspension wishbones are forged from aluminium to reduce the unsprung mass. These are similar in weight, and stiffer than the steel items found on the much smaller Elise, Exige and Europa vehicles, and have a far higher vehicle weight capacity. They are attached to the front and rear modules via bespoke bushes. The Lotus Evora will use Bilstein high performance dampers and Eibach springs with unique dual path top mounts for optimised vehicle refinement. Hydraulically assisted power steering is provided by a Lotus tuned TRW steering rack.
All in all, the Lotus Evora delivers. It has incredible Lotus handling and provides unsurpassable driving pleasure. In fact, word from the ride and handling team is that the new car is likely to become a class standard-setter for speed and agility.
Stop right now... Vented and cross-drilled brake discs - massive 350mm items on the front and 332mm at the rear - and high performance bespoke Lotus AP Racing 4 pot callipers ensure impressive stopping power.
Everyone connected with the brake testing programme, conducted on the punishing corners, climbs and descents of the Nürburgring, has described the brakes as 'phenomenal' with excellent thermal performance and outstanding feel even after extended sessions of extreme use.
Part of that testing programme was to finalise settings for the ABS system being developed in conjunction with Bosch. The system is set to very high thresholds and operates so progressively that drivers are often unaware that they have actually triggered the ABS.

Safe. Fun. Lotus Traction Control
The Switchable Lotus Traction Control (LTC) system has been developed simultaneously with the ABS and works through the engine management system to reduce power when required to maintain traction. Unlike many traction control systems, LTC has been tuned to complement the skills of the driver without taking over. The Lotus LTC is active above 5 mph (8 km/h) and operates much more quickly than many brake based systems. The system can be deactivated completely, giving no traction control intervention.

Keeping a grip - 18 inch at the front, 19 inch at the rear
Tyre choice is a vital component in the handling performance of every Lotus and for the Lotus Evora, Yokohama was chosen as development partner.
Lotus's long-term relationship with Yokohama was swiftly rewarded during development when initially the front tyre size did not generate the Lotus required lateral grip, the Japanese grip gurus went away and developed bespoke tyres especially for the Lotus Evora - a 225/40 ZR18 at the front and larger diameter; 255/35 ZR19 at the rear. Both have carcass construction and a rubber compound unique to Lotus and are identified by the letters 'LTS' on the sidewalls.

Lotus Elise Club Racer, 2010

Lotus Elise Club Racer, 2010

 



The Special Edition Lotus Elise Club Racer introduces new and exclusive colour schemes, bespoke interior and lightweight components all in a world class, high performance and low emission sportscar.

Lotus has taken four of the classic colour schemes used by Lotus in the 1960s (Elite Yellow, Carbon Grey, Sky Blue and Old English White) and combined them with exclusive Club Racer interior design features to give a stunning sportscar that beautifully morphs function and form.

The firm and supportive Lotus Elise seats are clad with lightweight microfibre comfort pads perfectly positioned to give the right amount of support with the minimal amount of weight, but still keeping the body coloured seat shell partly exposed.

The exterior body colour theme is carried over to the transmission tunnel and combined with silver and black paint highlights, bisecting the cockpit and tying together the whole sporty theme unique to the Lotus Elise Club Racer.

Another exclusive interior design features of the Lotus Elise Club Racer are the anthracite anodised gear knob and handbrake sleeve, the Club Racer (CR) logo hand embroidered on the seat headrest and the unique anodized aluminium flooring in the driver's and passenger's footwell. The small 320 mm diameter leather rimmed steering wheel has an on-center marker, enabling the more spirited driver to quickly and safely identify the straight ahead position of the front wheels.

The lightweight six spoke alloy wheels, shod in bespoke Yokohama AD07 LTS tyres are also anthracite anodised, complementing the key interior components.

Lotus Exige Cup 260, 2010

Lotus Exige Cup 260, 2010


 

The 2010 Lotus Exige Cup 260 takes the design and aerodynamic changes first introduced on the Lotus Exige S earlier this year to enhance the look and improve aerodynamic performance.

The lightweight, unpainted carbon chord composite rear wing is based on the design from the Exige GT3 road car concept shown at the Geneva Motorshow in 2007. Compared to the 2009 Lotus Exige Cup 260 tailgate-mounted wing, it is 181 mm wider and mounted 46 mm higher and 61 mm further back. It is attached to the rear bodyshell clam via rear end plates which not only increases the stiffness of the whole structure but also ensures that as much of the airflow as possible passes over the rear wing. This careful airflow management increases stability, reduces drag and, most importantly, maintains the impressive downforce figures of 42 kg at 160 km/h.

Rear chassis stiffness increases by 30%
The Lotus Exige Cup 260 now has an evolution of the rear diffuser and structural shear panel based on the version developed for the Exige GT3 race car, which increases the lateral stiffness of the rear subframe by 30% further enhancing its outstanding handling.

The rear diffuser and structural shear panel links the subframe to the main chassis to give greatly increased lateral stiffness to the rear subframe suspension pickup points, resulting in better tyre contact patch control.

This stiffness is also more applicable to those drivers who race or take part in track days using slick tyres that can also be fitted to the Lotus Exige Cup 260.
Ohlins two-way adjustable dampers are now fitted as standard, adding even more personalisation of the driving characteristics so the driver can tune the Lotus Exige Cup 260 to their driving style and road or track conditions.

A restyled front end and new larger, rear wing that not only reduces drag, but also gives a more muscular stance enhancing the lightweight shrink-wrapped look of the whole car.

Like the 2010 Lotus Exige S, the 2010 Lotus Exige Cup 260 exploits the Lotus philosophy of using weight reduction to increase performance and reduce emissions. Fuel economy is impressive with an Official European Combined Cycle figure of 8.5 litres / 100 km (reduced from 9.1 litres / 100 km (combined) for the 2009 Lotus Exige Cup 260), a frugal 6.5 litres/100 km on the Official European Extra Urban Cycle and just 199 g/km of CO2 (reduced from 216 g/km of CO2 for the 2009 Lotus Exige Cup 260). Continuous engineering improvements over the last year including careful whole vehicle optimisation has enabled this sportscar to be even better for fuel economy and emissions.

Carbon fibre (resulting in a weight saving of 12kg):
    * Roof Panel
    * FIA and HANS compliant driver and passenger seats
    * One piece carbon fibre dash top panel
    * Rear tailgate
    * Centre tunnel
    * Front access panels
    * Front splitter (carbon chord)
    * Side air intake ducts
    * Rear spoiler (carbon chord)

Lightweight components (resulting in a further weight saving of 22kg):
    * Lightweight 'motorsport' battery
    * Ultra-light five spoke forged alloy wheels
    * Revised rear engine subframe with lightweight coating
    * Lightweight fly wheel
    * Lightweight composite bulkhead panel replaces rear window
    * Alloy supercharger U-bend pipes
 
Removing some other non essential components and equipment such as the interior and boot carpets, front mudflaps, battery cover, interior mirror, sunvisors, rear tailgate gas strut, results in a further weight saving of 4kg.

However, as optional extras should a customer wish, air conditioning and an interior noise reduction pack are available, together with the complete range of Lotus metallic, lifestyle and premium paint colours

The 2010 Lotus Exige Cup 260 weighs in at just 890 kg, giving an impressive power to weight ratio of 288 hp / tonne (291 PS / tonne). But, of course, power to weight alone does not make a highly competitive race or track car, so in addition, the Lotus Exige Cup 260 has a formidable list of standard performance focused equipment, as follows:-

Lotus Launch Control and Lotus Traction Control - additions recommended for track driving
The launch control allows the driver to determine the number of revs they wish to use during a standing start. Having programmed that limit, the driver then holds their foot down fully on the throttle pedal and sidesteps the clutch pedal for a very quick departure from the line. The clutch damper cushions the severity of the clutch to transmission engagement to minimise the stresses to the drivetrain. The launch control also keeps wheel-spin at bay until 10 km/h (6 mph), after which the traction control assumes its duties.

As with launch control, the amount of traction control required can be dialled in from the driver's seat and altered on the move to suit the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely inactive. The message display in the new instrument pack displays what degree of traction control is being currently utilised.

Wheels and Tyres

All new Lotus Sport lightweight forged alloy wheels, thought to be the lightest original equipment wheels in the world, weigh just 5.65 kg (front) and 7.75 kg (rear). These ultra lightweight wheels reduce the unsprung mass therefore further improving the handling and contribute a weight saving of approximately 800 g over the already super light forged 2009 Lotus Exige Cup 260 wheels. The wheels are shod with Lotus specific LTS construction and compound Yokohama A048 tyres to maximise grip and achieve the ride and handling targets set by Lotus engineers.

Safety Equipment

Lotus Exige Cup 260 cars have the safety equipment expected of a race car, with FIA and HANS compliant carbon fibre lightweight sports seats, normal 3-point "Webb Lock" harnesses (four or six point driver and passenger seat belt harnesses are available for track use only).

A high tensile steel roll over hoop is now fitted with a body coloured Lotus Sport A-Frame as standard and the chassis is already pre-drilled to fit a full front roll cage - a simple dealer fit process involving just the removal of the roof panel for access prior to fitting. Completing the additional safety equipment is a FIA compliant electronic ignition kill switch, with cockpit and external activation, and a FIA compliant plumbed electrically activated fire extinguisher system, again with cockpit and external switches.

Like all current Lotus cars, the Exige Cup 260 is built around a very strong extruded and bonded aluminium chassis tub. Attached to the chassis is a sacrificial energy absorbing composite front structure designed to help absorb crash energy in the event of impact.

Suspension

To suit individual driving styles and road conditions, drivers will now be able to tune the Exige suspension with the Ohlins two-way adjustable dampers (which have 60 compression and 22 rebound settings) and ride height adjustment to reduce the ride height from 130 mm to 120 mm. An adjustable front anti-roll bar allows customers to tailor the handling characteristics of the car to their own requirements.

As the Lotus Exige Cup 260 cars are equipped for track use, a double shear track control arm brace is provided to cope with the expected kerb abuse during track racing or hard track day driving.

Brakes

The brake system includes large diameter 308 mm 2-piece cross-drilled and ventilated front discs and 282 mm cross-drilled and ventilated discs at the rear, upgraded Pagid RS14 sports brake pads set into the brake calipers (AP Racing two piece radially mounted, 4 piston at the front and Brembo sliding at the rear), and stainless steel braided brake hoses - all linked to the proven Lotus track-tuned servo-assisted four-channel ABS system that enhances braking performance and minimizes stopping distance without taking over from the skill of the driver.

Performance, Economy and Emissions

The Lotus Exige Cup 260 is one of the quickest road cars around a circuit. Key to this incredible track performance is the aerodynamic package, which produces 42 kg of downforce at 160 km/h (100 mph) increasing grip and stability at higher speeds. With a top speed of circa 245 km/h (152 mph) and a zero to 160 km/h (100 mph) in circa 9.9 seconds, 0 to 100 km/h in circa 4.1 seconds (0 to 60 mph in circa 4 seconds), the 2010 Lotus Exige Cup 260 is the perfect partner for the serious racer. Combined Fuel Consumption is 8.5 l/100km and the CO2 emissions 199 g/km.

Engine

The supercharged and intercooled engine in the Lotus Exige Cup 260 has a maximum power output of 260 PS (257 hp) at 8000 rpm and a torque figure of 236 Nm (174 lbft) at 6000 rpm. This significant amount of extra power and torque now available together with the VVTL-i variable cam system ensures that there is a smooth and linear delivery of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The Roots-type Eaton M62 supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine's oil) is run from the crankshaft and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through an air-to-air intercooler (the air enters via the enhanced roof scoop) before being fed into the engine itself. All charge air ducting has been kept as short as possible with large diameter pipes to minimise restriction and maximise throttle response and efficiency. Four high capacity injectors and an uprated fuel pump add additional fuel under hard acceleration or continuous high speed driving - only on the track of course!

A lightweight flywheel is fitted (giving even greater flexibility and response to the gear change), a sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to the lightweight C64 six-speed gearbox (with an aluminium casing) - with the same perfectly spaced ratios as the Exige S. A torque-sensing limited slip differential is fitted as standard, with a plate type limited slip differential available as an option. An Accusump (engine oil accumulator unit) is included in the whole package as an oil reservoir back-up for extreme track use ensuring that, under those conditions, the engine oil pressure remains constant.

Electrical supply is provided by a lightweight motorsport battery which saves a massive 5 kg of weight sitting behind the rear axle - again weight saving is not just the removal of mass but ensuring that this mass is removed where it most affects performance and handling.

Roof Scoop
The Lotus Sport Exige Cup 260 has a high flow, full-length carbon roof scoop as part of the lightweight carbon roof panel, which not only saves 4 kg but also ensures efficient cooling through the intercooler, which in turn allows the Lotus Exige Cup 260 to gain a higher charge density in the cylinders improving efficiency further.

Lotus Evora Type 124 Endurance Racecar, 2010

Lotus Evora Type 124 Endurance Racecar, 2010



The Lotus Evora Type 124 Endurance Racecar has been developed from the award-winning Lotus Evora road car and is built to FIA regulations and safety standards.

The Lotus Evora Type 124 Endurance Racecar is the next step in the evolution of the Evora. The car will make its 24 hour racing debut at the ADAC Nürburgring 24 Hours which provides a great test for the Evora's performance, efficiency and durability under tough and demanding endurance race conditions.

At the heart of the Lotus Evora are fundamental racecar elements: mid-engine layout, high-tech and super-stiff extruded and bonded aluminium chassis and very strong lightweight forged aluminium wishbones. All these elements mean that it is a natural evolution from the road going Lotus Evora to a competitive endurance racecar.

From the outset the design team had intentions to take the Evora racing and the chassis was designed with this in mind. Endurance races are the perfect events to showcase the efficiency, handling and durability characteristics that have been fundamental to the concept of the Evora.

The Lotus Evora Type 124 Endurance Racecar has a race-tuned version of the mid-mounted Toyota V6 engine, with power increased to over 400 ps (depending on race regulations). Vehicle mass is expected to be reduced by up to 200 kg, bringing the weight of the racecar to less than 1200 kg (depending on race regulations).

Further changes for the Lotus Evora Type 124 Endurance Racecar include a six speed sequential paddle shift racing gearbox, full FIA specification roll cage, FIA-compliant 120 litre ATL fuel system, FIA fire extinguisher system, competition carbon fibre rear wing, diffuser and front splitter.

The racecar is fitted with AP Racing 6 piston callipers front and rear, with a race-tuned Bosch ABS system, 4-way adjustable dampers and adjustable anti-roll bars. The racecar runs on 18" rims shod with Pirelli racing slicks and the wheels widths have been increased over the roadcar to 9 ½ J on the front and 11 J on the rear.

The aerodynamically efficient Lotus Evora Type 124 Endurance Racecar body design, made from lightweight composite and carbon fibre panels, remains predominantly unchanged from the road car, with the only modifications being to the lower sections of the front and rear clamshells and the side sills.

The racecar is expected to compete in a number of endurance races in 2010/2011 forming part of a factory-supported race program. The races that are targeted are: The 2010 ADAC Nürburgring 24 Hours (Nürburgring Nordschleife, Germany) in May 2010, Merdeka Millennium 12 Hours (Sepang, Malaysia) in August 2010, BritCar 24 Hours (Silverstone, UK) in October 2010 and the Dubai 24 Hours (Dubai Autodrome, UAE) January 2011.

Lotus Elite

….enjoy the new British Expression of Exclusivity
Ten days ahead of the official unveil at the Paris Motor Show the sun starts to rise for the dawn of Lotus’ new era - the Elite will redefine “modern classic”. So here it is, the Lotus Elite, the first taste of what’s to come from Lotus in the future. Look up elegant in the dictionary and you’ll find variations on the following 1. dignified grace in appearance, movement, or behaviour, 2. superb taste in design, style and 3. something elegant; the ultimate refinement.
The ground-breaking new Elite is exactly that. It’s compact yet chic body is elegance incarnate. It’s not only exquisitely elegant, in keeping with Lotus’ core values, it’s a car of substance incorporating some of the very latest technological innovations Lotus has to offer. The slick retractable hard top version and the optional use of hybrid technology with KERS are typical examples of Lotus tailoring technology to deliver perfect performance.
Dany Bahar, CEO of Group Lotus said: “There’s no denying that the Elite is breathtakingly beautiful to look at but it’s so much more than that, it’s a car that over delivers in all other aspects as well. One could say it’s a car of perfect contradictions, it’s compact yet spacious, high performing yet low emitting, lightweight yet still reassuringly solid. It’s a car that we are exceptionally proud of at Lotus and we truly believe that there is nothing else like it out there both in terms of styling and performance.
“Make no mistake, there’s a definite market requirement for the Elite – it’s the ultimate sports car feel with comfort and space. There will always be those who believe that Lotus should stick to small sports cars but we didn’t take the decision to design something like the Elite lightly, it’s based on months of careful research and planning. It’s worth noting this sector has been very successful for us in the past and now the Elite raises the benchmark higher still.” Set for release in spring 2014, this is an innovative, exciting GT that will set a new benchmark in design, performance and emissions. And it’s not all about sleek lines and stunning bodywork with this particular 2+2, what hides beneath this shark like exterior perfectly does the aesthetics justice. A front-mid positioned 5.0l V8 engine delivering up to 620 PS meaning drivers can expect to go from 0-100 km/h in approximately 3.5 to 3.7 seconds. ENDS

First up, the Elite will offer a retractable hardtop roof, adding significant weight to the automobile. It may weigh in at 3,600 pounds.  This is a far step from Lotus’ usual super-light vehicles mentality. The Elite has a 2+2 seating configuration and is directly aimed at the competing with the Ferrari 612.
"Make no mistake, there's a definite market requirement for the Elite - it's the ultimate sports car feel with comfort and space.

As for the new, awesome design of the car, the designer Donato Coco has designed what can only be described as a truly stunning car. It is completely different from all Lotus models of the past and really indicates that Lotus is ready to move from the ‘affordable’ sports car market deep into supercar territory.
With the likes of Porsche, Aston Martin and Ferrari in its crosshairs, it’s not surprising that the new Lotus Elite sports car is significantly heavier and more powerful than the company’s current offerings. In fact, with an expected kerb weight of 3,637 pounds, the Elite is very different to Lotus’ usual assortment of light weight track cars but its designers are confident it will still have the ultimate sports car feel--just with a little more comfort and space. The design, specification and performance figures for all Production Intent Prototypes will be confirmed following official testing and will be available from Lotus Cars.

Lotus Sports Cars Evora Type 124 Endurance Racecar

Proton-owned and British-based sports car maker Lotus has announced the Evora Type 124 Endurance Racecar (pronounced One Twenty Four). Based on the Evora road car, it is powered by a mid-mounted Toyota V6 powerplant. The engine is race-tuned and can output over 400PS, depending on race regulations. The power unit is linked to a 6 speed sequential transmission with steering wheel-mounted paddle shifters. It can weigh less than 1,200 kg, again depending on race regulations, thanks to an aluminium chassis, very strong lightweight forged aluminium wishbones and lightweight composite and carbon fiber panels.
Lotus Sports Cars Evora Type 124 Endurance Racecar
The Lotus Evora Type 124 Endurance Racecar has been developed from the award-winning Evora road car and is built to FIA regulations and safety standards. Based on the standard Evora road car, the Evora Type 124 (pronounced One Twenty-four) will make its 24 hour racing debut at the ADAC Nurburgring 24 hours race. According to Lotus, the Evora was designed for racing from the start and this made it very easy for the team to convert the Evora into a racecar, thanks to the mid-engine layout, stiff bonded aluminium chassis and lightweight forced aluminium wishbones for the suspension.
The Type 124 (pronounced One Twenty Four) Endurance Racecar is the next step in the evolution of the Evora. The car will make its 24 hour racing debut at the ADAC Nürburgring 24 Hours which provides a great test for the Evora’s performance, efficiency and durability under tough and demanding endurance race conditions.
The Evora gets a race-tuned version of the Toyota V6 mated to a 6-speed sequential paddle shift racing gearbox, and it now produces over 400 PS which is well over the 100 PS per liter ratio. I wish they’d listed out more specifications as to the specs of the engine – I dig this kind of stuff. In stock form, the Evora makes 280 horsepower from its 3.5 liter V6 engine, but even for the road car its said that a supercharged version could come later putting out over 400 horses.
At the heart of the Lotus Evora are fundamental racecar elements: mid-engine layout, high-tech and super-stiff extruded and bonded aluminium chassis and very strong lightweight forged aluminium wishbones. All these elements mean that it is a natural evolution from the road going Lotus Evora to a competitive endurance racecar.
From the outset the design team had intentions to take the Evora racing and the chassis was designed with this in mind. Endurance races are the perfect events to showcase the efficiency, handling and durability characteristics that have been fundamental to the concept of the Evora.
The Lotus Evora Type 124 Endurance Racecar has a race-tuned version of the mid-mounted Toyota V6 engine, with power increased to over 400 ps (depending on race regulations). Vehicle mass is expected to be reduced by up to 200 kg, bringing the weight of the racecar to less than 1200 kg (depending on race regulations).
Further changes for the Lotus Evora Type 124 Endurance Racecar include a six speed sequential paddle shift racing gearbox, full FIA specification roll cage, FIA-compliant 120 litre ATL fuel system, FIA fire extinguisher system, competition carbon fibre rear wing, diffuser and front splitter.
The racecar is fitted with AP Racing 6 piston callipers front and rear, with a race-tuned Bosch ABS system, 4-way adjustable dampers and adjustable anti-roll bars. The racecar runs on 18” rims shod with Pirelli racing slicks and the wheels widths have been increased over the roadcar to 9 ½ J on the front and 11 J on the rear.
Loads of goodies are added to the car – AP Racing 6 pot brakes on both front and back, a race-tuned Bosch ABS system, 4-way adjustable dampers, adjustable anti-roll bars, 18 inch wheels (nice and wide 9.5 from and 11 at the rear) with Pirelli slicks, a full FIA rollcage, an FIA 120 liter ATL fuel system, FIA fire extinguisher, yet weight is cut down from the production car to under 1200kg depending on race regulations. This is thanks to the use of carbon fiber extensively in the rear wing, diffuser, font splitter, and body panels.
The aerodynamically efficient Lotus Evora Type 124 Endurance Racecar body design, made from lightweight composite and carbon fibre panels, remains predominantly unchanged from the road car, with the only modifications being to the lower sections of the front and rear clamshells and the side sills.
Luke Bennett, Director of Lotus Cars Limited, said, “Motorsport has been in our blood ever since our founder, Colin Chapman, built the first Lotus back in 1948. We are proud of our motorsport history, which includes victories in Formula One, Le Mans, saloon car, rally car and sportscar racing around the world; more recently, we won the British GT3 Championship in 2006 with the Lotus Exige. The Lotus Evora Type 124 Endurance Racecar is from the same unique stable and we expect it to be a competitive racecar when we enter various endurance races next year.”
Roger Becker, Vehicle Engineering Director for Group Lotus Plc said, “Every Lotus car is designed to be at home on the race track as well as the road, and the Evora is no different. Designed primarily as an everyday road car, the Evora’s lightweight and stiff structure, its aerodynamics and performance means that it is perfectly suited to taming race tracks around the world, and we are looking forward to seeing the new Lotus Evora Type 124 Endurance Racecar line up on the grid for the 2010 season.”
The racecar is expected to compete in a number of endurance races in 2010/ 2011 forming part of a factory-supported race program. The races that are targeted are: The 2010 ADAC Nürburgring 24 Hours (Nürburgring Nordschleife, Germany) in May 2010, Merdeka Millennium 12 Hours (Sepang, Malaysia) in August 2010, BritCar 24 Hours (Silverstone, UK) in October 2010 and the Dubai 24 Hours (Dubai Autodrome, UAE) January 2011.

2010 New Lotus Sports Cars Exige S240

British performance sports car manufacturer Lotus has officially unveiled their 2010 Lotus Exige S240.  While Lotus fans will recognize this as a very subtle update, the grille and rear wing facelift is a step forward for the mark. The exciting new 2010 Lotus Exige S240 enters the United States and Canadian markets in the fall of 2009 with new front styling, a new rear wing and the same rare combination of exceptional performance and high efficiency.
2010 New Lotus Sports Cars Exige S240
The Lotus Exige S240 features a roof integrated air intake scoop feeds air through the air-to-air intercooled and supercharged 1.8 liter Lotus-tuned and Toyota-sourced 2ZZ-GE engine with Intelligent Variable Valve Timing (VVT-i) to provide 240hp at 8,000 rpm and 170 ft.-lbs. of torque at 5,500.
The 2010 Lotus Exige S240 sprints to 60 mph in a blistering 4.1 seconds and the 100 mph barrier sails by in approximately 10 seconds with top speed is 150 mph. The Lotus Exige S240 is equipped with a 6-speed transaxle synchromesh transmission, traction control and launch control. New for 2010, the optional Track Package will include adjustable Ohlins dampers with threaded spring perches and remote oil reservoirs front and rear.
The Lotus Exige is a renowned high performance coupe that has a well earned reputation as the choice for drivers who demand uncompromised performance, both on the road and on the track. The 2010 Exige S240 introduces a few key enhancements to update the appearance and improve aerodynamic performance. A restyled front end and new larger, low drag rear wing, not only reduces drag, but also gives a more muscular stance enhancing the lightweight shrink-wrapped look of the whole car.
Passing along lessons learned on the track with the Exige GT3 racing program, Lotus Sport Cars has contributed another important technology – variable launch control combined with variable traction control. The launch control allows the driver to determine the number of revs they wish to use during a standing start. Having programmed that limit, the driver then holds their foot down fully on the throttle pedal and sidesteps the clutch pedal for a very quick departure from the line. The clutch damper cushions the severity of the clutch to transmission engagement to minimize the stresses to the drivetrain. The launch control also keeps wheel-spin at bay until 6 mph, after which the traction control assumes its duties.
Like all Lotus cars, the functional components of the car are also beautifully designed as Russell Carr, Chief of Lotus Design, explains, "For 2010 we have taken the already visually extreme Exige and given it even more visual drama. The changes we have integrated to the front and rear of the Exige signal an even clearer and purposeful intent. The functional rear wing is race-inspired, the new angular air intakes and full width splitter give a more hard-edged and aggressive look. Overall, the Exige appears more planted and gives the illusion that both the front and rear of the car are wider than they really are, yet without losing its agile and sleek character."
The new 2010 Lotus Exige S240 is scheduled to launch in the US and Canada in the Fall of 2009. This new 2010 Lotus Exige S240 goes on sale this fall with a starting price of $65,690 and will be available in an upgraded track package with added performance benefits. The 2010 Lotus Exige S240 will hit U.S. and Canadian markets this Autumn.
