Gemballa

Uwe Gemballa's son Marc has decided to follow in pop's footsteps and start a business hotting-up supercars. First up: an "adventure sports" take on the Porsche 911. The Martien is a 750-horsepower sand-flinger that encourages off-road shenanigans.

We're mystified as to who exactly is buying all these damn hypercars, but whatever's happening at the demand end, the supply has never been more plentiful. Here's another we'll see in early 2020, boasting wild performance figures and exotic looks.

Gemballa is introducing what it calls the world's first diamond finish, a vehicle paint made from real diamonds.
