Cars concept imagine for production

The S5S Raptor was Saleen’s 2008 vision for a supercar that slotted in below the maniacal S7. The best part about it was that it was damn good looking. Had it been built, it would have been powered by a 5.0-liter supercharged V8 that made 650 hp. However, because of Saleen’s obvious financial woes, the car never wound up being built and we never got another great, American supercar.

The name, of course, comes from the Nardo test track, where Volkswagen set records with the prototype car. However, instead of building this car, VW went ahead and built the Bugatti Veyron instead. You can definitely see tones of the W12 Nardo in the Veyron, but there is something even cooler about the idea of a supercar from the company that brought you the people’s car.

In 2009, Bugatti released the Galibier concept: A sedan wearing the Bugatti badge that could potentially be the Veyron’s successor. It certainly looked related to the Veyron, too. It even kept the Veyron’s W16 engine, but, ultimately, Bugatti went with the Chiron as the Veyron’s successor instead of this crazy super sedan.

Beneath the hood that stretched past the horizon lay a V16 engine that was good for 1000 hp and 1000 lb-ft of torque. Cadillac unveiled the concept in 2003 as a nod to the famed Cadillac V16 from the 1930s. The engine was a 13.6-liter beast, and it was such a pity that these never made it to the road. It could have resurrected the great American grand touring luxury tradition.
