Lotus->ke49 has already unveiled the new Exige S, but that doesn't mean people have forgotten about the old version. In fact, Frank Profera from California wasn't very pleased with his stock Exige->ke525 so he did some improvements that transformed the car into the "world's fastest Lotus." Or at least that' what he claims.

Profera has spent six years making his Lotus go faster, stop shorter, and corner harder. After all this work, the 1.8 liter engine of his Exige model delivers a total of 680 wheel horsepower. And when the sports car's 2,150 lbs weight is considered, that's a better power-to-weight ratio than Mario Andretti's Formula One Lotus. That being said, this a project that may never be finished because of Frank's never-ending obsession with speed.
