The VW Lupo is a decent car. Sporty even in some cases. But adding Porsche Turbo brakes and 18" OZ rims seems a tad over the top. That is, until you see that big V6 poking out through the hood cutout. We can't imagine how nose-heavy this little runabout is with that lump out front, but fortunately we don't have to. The creators decided to take a novel approach to counter that weight over the front axle. They put another VW V6 in back. One powers the front wheels, the other powers the rears. Makes the roll cage an entirely logical addition now.
The Google translation from the original French helps us understand nothing more than that the builder wanted a little more zip in his Lupo and decided to use a Golf V6. But that wasn't quite peppy enough, so he thought of turbocharging the car. That seemed too expensive and so he went the twin-engine route. That makes about as much sense to us as it does to you. Although we haven't built many projects like this ourselves, sometimes you wonder what possesses people to spend so much time and energy on a vehicle with shortcomings that will require untold hours and dollars to remedy. And then we realize that it doesn't really matter what we think. This guy (or gal) decided this is what he wanted to do, and did it. That's probably why there's only one seat inside. More power to him. Literally.
