The butterfly-doored coupe looks very promising in bare carbon fiber, as is word that the prototype was spotted at Willow Springs raceway with British Le Mans champion Justin Bell behind the wheel for testing duties.
This GTX mule certainly has some interesting details to it, including the aforementioned up-and-forward doors, as well as a U-shaped vented hood, center-exit exhaust, a big (and likely temporary) adjustable wing, and funky contrasting fender treatments which may or may not see production.
It isn't altogether clear what engine will be powering this beastie, but Priddy's people reportedly overheard the engineers talking of extracting 650 horsepower out of the drivetrain. California-based Devon, you may recall, was the sole bidder Chrysler reported for its Viper franchise, and it's certainly conceivable that despite the failed bid attempt, the car seen here would still feature a certain 8.4-liter V10 underhood. Indeed, given that Devon continues to tout its creation as "America's next great supercar," that scenario seems rather likely.
The GTX is slated to make its first appearance at next month's Pebble Beach Concours D'Elegance (we'll be sure to grab some live photos), and the coupe is tipped to go on sale in the U.S. first in 2010, with other markets to follow. Check out the gallery of renderings below as well as a video of the teasers after the jump.
