American tuner Heffner Performance has been working on their twin-turbo package for the V8-powered Audi R8 and apparently they are in final stages of development. Here’s some new pictures and a video of the car. Don’t expect a massive body kit or anything though, as it looks like a standard R8. But the real beauty of this cars lied beneath the hood! Heffner has done a neat job here.

Those turbo airbox casings and marvelous exhausts are actually so mechanically beautiful that you if you buy one of these, you might want to remove the rear bumper and the hood to show them off! Of course this system works as good as it looks. The standard 420 hp is bumped to 543 hp on the rear wheels, which is even more than the V10-powered R8. But that’s just the beginning, feed this engine with 100 octane gasoline and it has the potential to churns out as much 723 hp!

But the coolest thing about this car is the fact that it looks like a normal R8. It fools everyone, until you put your foot on the throttle, then all hell breaks loose!!!
