Devel presented their Sixteen concept hypercar at the 2013 Dubai Motor Show. Claimed to produce 5,000 HP from a 12.3 L (12,291 cc) V16 engine that allows 0-60 mph in 1.8 seconds and a top speed of 560 km/h (348 mph).

The 320 mph target is supposed to be achievable by the "mid-level" 3000 horsepower version of the car, not just the 5007 hp everybody keeps talking about. There's also the fact that its American-made V16 engine is real, and way more elaborate than you'd imagine. And then, there's perhaps the most important piece of the puzzle, Chief Engineer Paolo Garella. The former head of Pininfarina's one-off division is mostly known now for designing Jim Glickenhaus' race and road cars, and more recently, working on Apollo's V12-powered IE hypercar.
