Lotus Eterne
2015 Lotus Eterne - 2010 Paris Auto Show
The Eterne is a true four door, four seater sports GT. It’s the ultimate expression of refined style, sophistication and grace. But wait. An elegant, graceful sports car? Surely not. A sports car by definition can’t be graceful. Powerful, exciting, aggressive yes, but not graceful. Yet here it is, the ultimate paradox - the Eterne. Power and grace, performance and elegance, beauty and strength all in one stunning package. With a 5.0 litre pressure charged V8 engine delivering up to 620 PS the Eterne is aiming for best in class performance and efficiency. In keeping with the rest of the new line-up, the Eterne will benefit from hybrid technology. Dany Bahar, Chief Executive Officer of Group Lotus, said: “The Eterne is sensational to look and as with the rest of the range it also over delivers in all other aspects as well. Similar to the Elite, it’s a car of perfect contradictions, it’s compact yet spacious, high performing yet low emitting, relative lightweight yet still reassuringly solid.” “We truly believe that there is a market for the Eterne, there is nothing else like it out there both in terms of design, capacity and performance. The biggest difference between the Eterne and it’s class competitors is that it’s not an evolution of an existing two-door model, it’s a deliberate and considered stand-alone creation. It’s the ultimate four door sports car.”
Specification of Eterne are Layout 4 seater, front-mid-engined, rear wheel drive, all wheel drive is optional. Engine Petrol, hybrid optional. Hybrid Technology Hybrid gearbox with integrated electric motors and KERS. Cylinder V8. Capacity 5.0 litre. Power/Torque 620 PS / 720 Nm. Rev limit 8,500 rpm. 0-100 km/h 4.0 seconds.

Lotus Evora Enduro GT Concept

Lotus has unveiled the new Lotus Evora Enduro GT race car at the 2011 Geneva Motor Show in Switzerland. The Evora Enduro GT Concept is the base car for the new Lotus GT2/GTE car that will be racing in the Intercontinental Le Mans Cup this season and is an evolved version of the Lotus GT4 Endurance. Lotus Motorsport, under the supervision of lead designer Nicola Scimeca developed the new car.
The vehicle rides on 18 inch forged alloys wrapped in 24/64-18 - 27/65-18 tires front and rear, while providing the necessary stopping power is a performance brake system with 22 mm race pads, two piece aluminium belled discs and 6 piston callipers at the front and 4-piston calliper at the rear.
Powered by a mid-mounted 4-litre DOCH V6 VVT-i engine, naturally aspirated and tuned by Cosworth, the Lotus Evora Enduro GT Concept develops 440 bhp @ 7,000 rpm and 460 Nm of torque @ 5,500 rpm.
The rear wheels get their power from the engine through an XTRAC 426 six-speed sequential gearbox. An optional pneumatic paddle-shift system can be fitted. Handling comes down to a forged double wishbone layout, four-way adjustable Ohlins TTX36 dampers, coaxial coil springs, increased camber, and adjustable anti-roll bars. Mated with racing slicks, it should prove formidable, especially with its mid-engine layout.

2012 Lotus Elise Club Racer

Lotus has releases a new entry-level sports car, the Elise Club Racer 1.6, priced in Europe from around $45,000. which will have its world debut at the Geneva motor show next month.
The Elise Club Racer is a full 52 pounds lighter than the standard car, and Lotus achieved this by removing the noise insulation and using a motorsport-derived lightweight battery. This might not seem like an enormous weight savings, but when you consider that the base Elise already weighs in under the 2,000-pound mark, even a small weight reduction is noticeable.
Powering the Elise Club Racer is the same 1.6-liter four cylinder VVT-I engine with an output of 136 PS (100 kW / 134 hp) as on the series' variant. Lotus did not provide new performance numbers for the Club Racer but the standard Elise does the 0 to 100 km/h (62 mph) sprint in 6.5 seconds, which the Club Racer can only beat, if but slightly.
Priced at �27,500 / �34,450 / $46,750, the Elise Club Racer marks the new entry level sports car from Lotus. Customers can choose from a range of six exterior colors (Sky Blue, Saffron Yellow, Ardent Red, Aspen White, Matt Black and Carbon Grey), plus various bespoke design elements.


Press Release
Lotus Elise Club Racer
Maximum fun, minimum collateral
Anyone harbouring under the misapprehension that Lotus might be moving away from performance through lightweight only needs to take a quick ride in the new 1.6 Lotus Elise Club Racer to know that's definitely not the case. The bright engineers at Lotus put even the lightest of Lotus' modern cars on a diet and managed to shed a further 24kg.
So how did Lotus manage to make one of the lightest models on the market even lighter? The engineers behind the Elise Club Racer took a stripped-to-the-bare-bone approach visualised by the body-coloured seats but materialised in many ways such as the motorsport derived lightweight battery and the deletion of noise insulation. Attention to even the smallest of details has ensured that Lotus' passion for performance through lightweight has been translated throughout the car.
For the first time ever an Elise variant comes complete with a Sport setting for the DPM (Dynamic Performance Management) allowing even the less experienced sports car drivers to feel at the top of their game, while the ability to switch it off completely will please the more established track orientated drivers. DPM combined with improved agility courtesy of Lotus finely tuned sport suspension and an adjustable anti-roll bar will make the Elise Club Racer equally versatile for both road and race track fun.
Wolf Zimmermann Chief Technical Officer Lotus Cars said: "The traditional Lotus approach of reduction and purity has lead to one of the most zeitgeist and contemporary sports cars around. For over 15 years the Lotus Elise has become an icon in the sports car market, carving out a niche market with a dedicated following of lightweight fans. The new Club Racer will definitely give these people something extra to get their teeth stuck into. This car epitomises everything that's cool about the Elise - it's fast, raw, responsive and a huge amount of fun to drive."
Quality throughout the vehicle has been a top priority, highly regarded component suppliers such as Eibach for springs and Bilstein for dampers ensure that the Elise Club Racer is a car of substance as well as style.
The Elise Club Racer pleases the eye as well as the soul with a choice of six striking colours (Sky Blue, Saffron Yellow, Ardent Red, Aspen White, Matt Black and Carbon Grey) and bespoke design elements that emphasise the character of the car.
It's pocket pleasing too, at �27,500 / �34,450 / CHF48,900, the Elise Club Racer marks the new entry level sports car from Lotus. And with the Elise standard of just 149g CO2/km plus the weight reduction, the new Club Racer provides maximum fun without so much of the green-guilt usually associated with high performance driving.
Lotus Elise Club Racer: Purity, performance, pleasure - a TRUE Lotus.

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 N�rburgring, 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 N�rburgring, 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.
