The Lotus Elise revolutionised the sportscar market 14 years ago when the small lightweight agile 2-seat mid engine sportscar was introduced. By ensuring that the Elise stuck rigidly to Lotus’ core values of performance through light weight, the Elise was able to produce supercar performance with city car economy.

Making its debut at the 80th International Geneva Motorshow, the 2011 model year Lotus Elise introduces a number of changes and improvements to maintain its class leading position.

Body

The new 2011 model year Elise range is on sale now and will be in showrooms from April 2010. The body of the new 2011 model year Elise is an evolution of the iconic Elise design, retaining the character and style, while offering a more planted, purposeful stance and a pure, contemporary look that links it to the Evora. As with all Lotus product the design is an exciting blend of dramatic style and functional efficiency. The new Elise body has a fresh sculptured front, including a new bumper, front clam and access panel that combine to give the Elise a wider look with more road presence.

At the rear of the car the new engine has been encased by a distinctive ‘twin-spine’ engine cover whilst lower down a more aggressive diffuser is tightly wrapped by an elegant new bumper design that now includes the rear licence plate.

Engine

The Lotus Elise introduces the new 1598 cm3, 1ZR-FAE engine, provided by Toyota. The key to this engine’s performance and efficiency is the Valvematic system (a variable valve lift mechanism), which is combined with the dual VVT-i (Variable Valve Timing-intelligent). The engine continuously controls intake valve opening/closing timing and the intake valve lift to vary the volume of the intake airflow, giving significant improvements in efficiency and fuel economy. This ensures optimal performance based on the engines operational condition, thus helping the Elise achieve both high fuel efficiency and high performance.

First of all, the maximum power output is achieved at near maximum revs (engine speed) of 6800 rpm and maximum torque (a respectable 160 Nm, 118 lb.ft) is reached at 4400 rpm. This gives a good combination of mid range pull but also encourages the driver to rev the engine to the maximum permitted engine speed of 7000 rpm (transient rev limit). Like all Elise sportscars, there are three shift up lights, on the binnacle cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that the driver is almost on the rev limiter so time to change up a gear!

The height of the engine cover has been raised by 34mm to accommodate the taller 1ZR engine compared to the previous 1ZZ engine from the outgoing model due, in part, to the additional Valvematic technology included on the new engine. This has given Lotus engineers an opportunity to subtly redesign the rear engine cover to match the design theme from the front and rear of the car.

Chassis

The Lotus Elise is built around the revolutionary and award winning extruded and bonded aluminium chassis, with a lightweight steel rear subframe. The chassis weighs 68 kg (150 lbs) and has a stiffness of 9,800 Nm per degree, giving a high level of control of the suspension. At the rear, and also acting as a rear energy absorbing crash structure, a lightweight steel subframe carries the engine and gearbox. At the front, the radiator and key ancillaries are mounted into a high tech composite energy absorbing crash structure that is both lightweight, compact and over three times more energy absorbing than the equivalent steel structure.

Ride and Handling

The legendary Lotus ride and handling gives a superb high performance, sporty drive, combined with a compliant ride and progressive on limit handling, it makes the Elise a car that demands to be driven. The entry level Lotus Elise weighs 876 kg, making it one of the lightest fully homologated sportscars in the world. This low weight translates into efficient performance with minimal environmental impact in terms of emissions and fuel consumption. The efficiency of the Elise structure means that the 136 PS (100 kW, 134 hp) delivers phenomenal performance. Few cars can match the delicacy and accuracy of the steering, throttle and brakes of the Elise and all of these factors contribute to the excellent driving experience of the Elise.

Safety

The Elise has high performance AP Racing callipers at the front and Brembo callipers at the rear linked to 282 mm vented and cross-drilled cast iron discs to give excellent stopping power. The Elise comes as standard with a track tuned ABS system that is designed to be unobtrusive under normal driving conditions. This system is designed to be used on track and has a high threshold, only intervening in emergencies. The ABS system is linked to a lightweight pedal box with steel pedal arms and extruded aluminium pads. This unit also has an electronic (drive-by-wire) throttle for quick, smooth and more linear engine response. The impressive braking coupled with excellent handling gives good primary safety and the composite front crash structure and rear crash protection offers efficient secondary safety. Driver and passenger airbags and pre-tensioning seatbelt are standard on all Elise models.

The Lotus Elise is currently undergoing EC Whole Vehicle Type Approval and official fuel consumption and CO2 emissions figures, plus performance figures are not yet available. The official figures for fuel consumption and CO2 emissions and performance will be published on Group Lotus plc’s web site as soon as they become available (www.grouplotus.com) or may be obtained from the PR Department, Lotus Cars Limited, Potash Lane, Hethel, Norfolk, NR14 8EZ, UK.

Interior

As soon as a driver sits behind the wheel of a Lotus, they instantly know that they are in something special. From the composite sports seats that hug the driver under the g-forces that are experienced on cornering, acceleration and braking, to the race designed steering wheel and the extruded aluminium pedals perfectly suited to both cruising as well as hard driving – the Elise is a car that invites to be driven.

The twin instrumentation dials show road speed and engine speed (for the 111R, now showing to 10,000rpm) and are updated for 2004 across the whole of the Elise range, with clearer graphics and orange back lighting which is proven to be easier on the eye. Links between the Elise and the track have always been strong, and the ambience of the facia and trim with the chassis tub sides provoke a strong sense of being seated in a racing derived but comfortable cockpit.

A four speaker Blaupunkt stereo system with CD player is provided as standard along with a radio receiver wiring loom including dipole aerial kit located in the front of the Elise 111R.

Equipment

Standard equipment for the Elise 111R includes: half leather interior, sun visors, central door locking, Blaupunkt Lausanne radio CD-R/W player and Blaupunkt high performance front and rear speakers

Optional equipment includes a Touring Pack, which provides a combination of options designed to increase comfort and convenience, while still maintaining the essence of a Lotus sports car. This pack includes:

Auxiliary front driving lights, a choice of either full leather or Alcantara trim, a soft-top with sound and thermal insulation, electric windows, an upgraded Blaupunkt Woodstock DAB radio, CD-R/W and MP3 player, interior stowage net, sound insulation, and full carpet with a lightweight aluminium passenger footrest.
