Opening the range is the Elise Sport 240 Final Edition, which sees the existing Sport 220's 1.8-litre supercharged four-cylinder engine uprated to develop and , permitting a zero to 100km/h time of 4.5 seconds. When fully specified with weight-saving options – namely carbon-fibre sill and engine covers, a lithium-ion starter battery and a polycarbonate rear window – the Sport 240 is the lightest car on offer, tipping the scales in at just 898kg. A set of 10-spoke forged alloy wheels fill the arches, measuring 16 inches in diameter up front and 17 inches at the rear, wrapped in Yokohama Y105 tyres. Lotus claims the new wheels are 0.5kg lighter than the examples fitted to the outgoing Sport 220.
