There’s nothing quite like a concept car to stir the imagination, and few stir harder than dreamy supercars that aren’t really intended for production. Freed from the burdens of safety, comfort, and profit, Peugeot tried to shake things up with the 907 concept.

The Peugeot 907 was first shown off in 2004. DriveTribe takes us back through the story of this one-off and how it came to be.

Commissioned as a study to celebrate the company’s new design center, the team was allowed to go all out for the 907. A rear-wheel-drive coupe, its body was made of carbon fiber and the engine was sat well back, making it a front-mid-engine car.

That engine was a 500 hp (506 PS/372 kW) naturally aspirated 6.0-liter V12 that was essentially made by sticking two of the company’s 3.0-liter V6s together. Tipping the scales at 3,086 lbs (1,400 kg), thanks to its carbon fiber body, the 907 it could get to 60 mph (96 km/h) in just 3.7 seconds and onto a theoretical top speed of 222 mph (357 km/h).

Sadly, the one-off was never intended to go anywhere past the concept stage, so it’s more of curiosity than one of the automotive world’s great what ifs. You can, however, hear it in the video below.

Now simply a fixture of the Peugeot brand museum, the concept doesn’t get out much. There is, however, a rumor that all the parts you’d need to make another engine are stored somewhere deep in the bowels of a Peugeot building somewhere. And with the world moving on and automakers going all-in on electrification, we guess that’s where they’re gonna stay.
