2003 Lotus Elise 135R


2003 Lotus Elise 135R

Developed by Lotus Sport and Performance in conjunction with the Lotus Ride and Handling team, the Lotus Sport Elise 135R has been designed to provide ultimate performance both on and off the track. Engine, suspension, wheel and tyre upgrades all contribute to what can only be described as the ultimate road and track Elise. Offering a more direct feel, the 135R affords the enthusiast driver with more immediate and sharper responses, developed to deliver exceptional driver involvement.

Engine

The power output of the engine is 135bhp. This has been achieved by modifying the ports of the cylinder head to improve gas flow, mixture and cylinder filling. The standard intake manifold has been replaced by a cast alloy version as used on the 111 range. Alongside a reprogrammed ECU these modifications further improve the Elise’s engine breathing’ allowing the driver to explore maximum engine revs in all gears increasing driver enjoyment, especially during track use.

Suspension

Lotus’ world famous Ride and Handling team has developed an optimum set-up for both road and track use. The Elise’s Bilstein dampers have been re-calibrated to give stiffer bump and rebound settings. The dampers are also fitted with adjustable upper spring platforms threaded onto the damper itself, offering a wide range of settings for any use. A stiffer adjustable anti-roll bar has also been fitted to provide optimum steering response.

Wheels & Tyres

The Lotus Sport Elise 135R is fitted with O.Z. Racing one piece lightweight cast alloy 16-spoke wheels. While the rear wheel size remains unchanged the front wheel size has increased from 5.5 inches to 6.5 inches to give a more positive turn-in during track conditions. The O.Z. wheels are fitted with Yokohama AO48 tyres which have been developed in conjunction with Lotus to suit the requirements of the performance driver, with special emphasis on track use.

Body

Externally the 135R will be recognisable by its striking colour and decals. Available in two new colours only, Silver Mica and Blue Mica, the 135R is fitted with two Lotus Sport 135R decals above each side repeater lamp and a larger decal at the rear. The F1 style diffuser has been utilised to accentuate aerodynamic performance.
