The Lotus Sport Exige is an all out race car version of the Exige. Weighing in at just 1874 lbs., it doesn't take much to get it moving but Lotus Sport dropped in a 400 HP tuned GM V6. That's a ratio of 4.685 lbs. per HP which beats out the Enzo with a ratio of 5.01 lbs. per hp. The car took just 6 months to complete and was done in absolute secrecy. The Exige was built for a South East Asian client and is expected to race in selected sportscar races in Asia. There are no plans as yet to build further examples of the Lotus Sport Exige but the base structure has been carefully designed to comply with key motorsport regulations around the world.
