2010 Lotus Evora







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.

Because one of the roles of the Lotus Evora is to attract new customers to the Lotus brand, much attention has been paid to its ease of use. Wider, taller door apertures and narrower sills make getting in and out of the cabin a less athletic undertaking than it is in Lotus's smaller sports cars (the Elise, Exige, Europa and 2-Eleven), while the design of the cabin itself will accommodate two 99th percentile (6ft 5in tall) American males in the front seats.

The 'convenience factor' of the Lotus Evora extends to less obvious areas of the car. For instance, beneath the skin the entire front-end structure is a high tech aluminium sacrificial modular unit, attached to the main extruded aluminium tub. This modular unit is designed to deform for maximum safety, and to reduce repair costs in the event of a frontal impact.

The Lotus Evora has been designed with global automotive regulations in mind, and future derivatives are planed, these including amongst others, a convertible.

The Lotus Evora will be hand crafted and built on a dedicated new assembly line within Lotus's advanced manufacturing facility at Hethel in the east of England; capacity limitations will restrict production to approximately 2000 cars a year, ensuring the dynamic new sports car's rarity and exclusivity.

Mike Kimberley, CEO of Group Lotus plc, has this to say about the exciting new model: "The Lotus Evora is the biggest milestone Lotus has achieved since the Elise was born 13 years ago and is part of our bold five year strategic plan, which includes the introduction of new cars and technologies to many more markets around the world. The Lotus Evora also represents Lotus core values of performance through light weight and efficiency and proves that you can have phenomenal performance, fuel efficiency elegant design and practicality all in a class leading mid-engine 2+2 sportscar, which will meet global safety and homologation standards"

Mike Kimberley continues, "Looking to the future, we will continue to research, develop and produce lighter, more efficient vehicles which are linked to our extensive and well-regarded work on all aspects of future fuels, alternative engines and electric and hybrid vehicle solutions for the future. We all have an environmental responsibility to future generations and the Lotus Evora is another example where Lotus is seen to make significant steps towards improving the efficiency and sustainability of the motorcar keeping Britain at the forefront of the high technology motor industry."

High-tech treats

Contemporary technology also features in the Lotus Evora's cabin. A newly developed Alpine multi-media system with a 7 inch touch-screen provides advanced audio, satellite navigation, video, Bluetooth® hands-free telephone and iPod® connectivity functions; the screen also serves as a monitor for the Lotus Evora's optional reversing camera. The satellite navigation element of the system is removable, allowing you to programme it from the comfort of your home, or take it with you to continue your journey in an unfamiliar pedestrian location.

The Alpine audio set-up is one of the most sophisticated automotive systems in the world. Called IMPRINT and using MultEQ sound enhancement technology, it is able to cancel out sound imbalances, caused by the cabin window glass, for instance, creating echoes, while carpets suppress mid-range frequencies - resulting in amazingly crisp, clear, undistorted sound reproduction wherever you are seated in the car.

A bespoke air-conditioning system developed by Bergstrom is standard on all models, and has been designed for the hottest climate or the closest humidity to help provide maximum occupant comfort. Lotus traction control and on-board tyre pressure monitoring will also be available.

One size fits all

The front seats themselves are very supportive and leather clad with a lightweight manual adjustment mechanism for fore and aft, rake and lumbar, designed to give a supported driving position.

The rear seats of 2+2 versions of the Lotus Evora are intended for children and smaller adults. There will also be a two-seater derivative with a luggage shelf in the back. To maximise comfort in the rear, there's a decent amount of foot-room under the seats in front, while both back seats feature ISOFIX mountings for secure child seat fitment.

When unoccupied, the rear seats provide a convenient stowage area, adding to the Lotus Evora's appeal as an everyday car. The 160 litre boot, which ingeniously features a fresh air cooling system to reduce the effect of any heat ingress from the engine bay, will also accommodate a full set of golf clubs.

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.

Safely does it

In common with the Elise and its derivatives, The Lotus Evora's bonded extruded aluminium chassis tub has incredible inherent strength, particularly in regard to side impacts. Additional torsional strength is given to the whole structure by the tubular steel seatbelt anchorage frame that also acts as a rollover structure.

Deformable sacrificial aluminium front and steel rear subframe modules are attached to the tub using joints which are designed to minimise damage to the tub, protecting the main passenger cell in the event of an accident.

Driver and passenger airbags are standard. The airbag on the passenger side is cleverly engineered to deploy vertically and then be deflected rearwards by the windscreen, to provide protection for children as well as adults.

Anti-lock brakes are standard on all models, as is Lotus Traction Control (LTC); these systems have been specially developed in co-operation with Bosch and enable up and coming drivers to consistently exploit the braking and acceleration capabilities of the Lotus Evora, whilst allowing skilled enthusiasts the freedom to enjoy the full Lotus driving experience.

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.

The V6 Engine - dual VVT-i ('intelligent' variable valve timing)

The exceptional working relationship that Lotus has enjoyed with Toyota over several decades, combined with the overwhelmingly enthusiastic reception for the company's four-cylinder power units in the Elise and Exige, guaranteed the Japanese giant's inclusion on the shortlist for the Lotus Evora engine supplier.

The final choice was Toyota's all-alloy 2GR-FE 3.5-litre V6 DOHC, with dual VVT-i ('intelligent' variable valve timing). Lotus has painstakingly developed its own T6e engine management software for this engine to optimise its compatibility with the unique requirements of the Lotus Evora to give a peak power output to 280 PS at 6400 rpm, while boosting its maximum torque to 342 Nm at 4700 rpm (prototype figures).

Changes to the engine management and exhaust systems also allow the V6 to rev more freely and provide rapid throttle response; feedback from the development team suggests that the strength of the engine's mid-range torque means that gutsy performance will be easily accessible without having to thunder through to the redline. This makes the Lotus Evora a thoroughly satisfying car for everyday road use and a rewarding one when you just want to drive.

The 2GR-FE V6 engine is mated to a manual six-speed gearbox, again Toyota-sourced. A close-ratio version of this gearbox is also currently under development for the even more sport-focussed driver.

Many Lotus owners enjoy the blend of unique performance and efficiency that the brand's cars offer. True to the Lotus value of "performance through light weight" CO2 emissions are expected to be a class leading sub-225 g/km (prototype figures) while testers report fuel consumption in the region of 30+ mpg (pending formal homologation testing).
