17. Arash AF10
The small British company, Arash, made news with several supercar prototypes. But there was one that was closest to full-scale production, and that was the AF10. They presented it in 2009, featuring a Chevrolet V8 pumping out a head-spinning 500 HP.
However, in recent years, they revised the car, giving it a new hybrid powertrain with a claimed power output of 2,080 HP. This insane number raised the eyebrows of the supercar public. But sadly, the company hasn’t said anything since that announcement.
