Btw: Some wacky germans (think they're germans) stuff a tweaked audi S-series engine in those elises if you front the cash, pushing out 420 sweet turbo horses. Fucking great!

Lotus Esthi that is (made by a german tuner called Dsch1/4dow Automobilmanufaktur), they put an Audi RS4 engine in it, so you get about 2,6kg per hp, which is pretty awesome!
