The Lotus Elise took the sports car world by storm when the small, lightweight and agile 2-seat mid-engine sports car was introduced. Can the Elise possibly be 14 years old already? Can we be so old that the Elise still counts as a "new" sports car?
Apparently so, because the newly updated 2011 Elise range will enter the US and Canadian markets in the late summer of 2010.
The 2011 Elise range for the US and Canadian markets will consist of the following versions:
• Lotus Elise – 1.8 liter, 4-cylinder engine with 189 hp and 133 ft.-lbs. of torque
• Lotus Elise SC – 1.8 liter supercharged 4-cylinder engine with 218 hp and 156 ft.-lbs. of torque
Key updates and improvements across the 2011 Lotus Elise line:
• New evolution body design incorporating new front clamshell, rear bumper and engine cover
• New all-in-one integrated headlights incorporating LED daylight running lights and LED direction indicators
• Improved aerodynamics with a four percent reduction in Coefficient of Drag (Cd), resulting in better fuel economy
• New standard cast and available forged wheels
Andreas Prillmann, Chief Commercial Officer for Lotus Cars said, “In its 14 years of production the Elise has accounted for 32% of all the 61 years of Lotus production, illustrating how significant to the brand and well loved it is. The 2011 Elise is greener, purer and more desirable, making it even more relevant in today’s marketplace. The new Elise underlines Lotus’ reputation as one of the most innovative sports car manufacturers in the world.”
The 2011 Elise in More Detail:
Front-PhotoHere's the low-down on the 2011 Elise and Elise SC.
Chassis
The Lotus Elise is built around the revolutionary and award winning extruded and bonded aluminum chassis, with a lightweight steel rear subframe. The chassis weighs just 150 lbs. and has a torsional rigidity of 9,800 Nm per degree, giving a high level of precise control of the suspension tuning. 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 lightweight, compact, and over three times more energy absorbing than the equivalent steel structure.
Body
The body of the new 2011 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.
The new Elise body has a new front end, including a new bumper, front clam and access panel that combine to give the Elise a wider, more planted stance on the road.
At the rear of the car the mid-engine compartment has been encased by a new, distinctive “twin-spine” engine cover while lower down on the back of the Elise a more aggressive diffuser is tightly wrapped by an elegant new bumper design that now includes the rear license plate.
The theme of purity is carried through to the cooling apertures that are efficiently finished with a new lightweight aluminium mesh that gives the car a classically sporting character.
With the sleek new body, the 2011 Elise’s aerodynamics have improved with a four percent reduction in the coefficient of drag (Cd).
Engine – EliseRear-PhotoPower for the Elise is delivered through the high-tech and reliable 2ZZ-GE 1.8-liter fourcylinder, 16-valve engine with Intelligent Variable Valve Timing (VVT-i) from Toyota. Selected for the Elise because of its compact size, light weight and high output, the Lotus-tuned engine is rated at 189 peak horsepower at 7,800 rpm, delivering 133 ft.- lbs. of torque at 6,800 rpm. VVT-i technology allows the engine increased low-end torque for better acceleration from a standstill while also enhancing high-speed performance.
The job of getting power to the ground falls to the smooth-shifting, all-aluminum C64 six-speed manual gearbox, also sourced from Toyota. Lotus engineers designed an ultra precise shift linkage mechanism for fast, positive gear shifts, transforming the transmission into the perfect tool for harnessing every ounce of the Elise’s performance potential.
Engine – Elise SC
The 2011 Elise SC has a power increase over the standard Elise from 189hp to 218hp (15%) and torque increase from 133 ft.-lbs. to 156 ft.-lbs. (17%) via an Eaton rotor pack non-intercooled supercharger designed especially for the Elise. The Lotus-designed, Magnuson-produced supercharger is joined to the intake manifold plenum as part of a single-piece casting. Combined with the absence of an intercooler and its associated pipework, this integrated supercharger/intake manifold assembly contributes to a 17.6 lbs. reduction in engine weight compared to the Exige S and no compromise to rear view mirror visibility which is masked by the current intercooler
installation on the Exige S.
In keeping with its role as a supremely fast road car rather than extreme track machine, throttle response is very progressive but also very direct, resulting in a measured, refined driving experience. As you might expect of a car with 218hp and weighing only about a ton, the performance of the 2011 Elise SC is astonishing with 0-60 mph acceleration time in the mid four second range.Both the naturally-aspirated Elise and the Elise SC’s supercharged engine are completely controlled by Lotus’ own bespoke T6 Engine Management Control System.
Ride and Handling
The Lotus Elise is one of the lightest fully homologated sports cars 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 189 hp in Elise form or 218 hp in the Elise SC delivers phenomenal performance.
Finally, a choice of two beautiful, light weight wheel designs are available. New standard cast alloy wheels have been designed specifically for the Elise. Also, new optional forged alloy wheels will be available that weigh just 64.5 lbs. per set, 4.7 lbs. lighter than the set of cast alloy wheels. Both wheel sets are available in silver or black.
Safety
The Elise has high performance AP Racing calipers at the front and Brembo calipers at the rear linked to 11.1” (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.
