Modifying muscle cars has become something of an art form in recent years. From the rising popularity of restomods that pair classic style with modern performance to the modern twin-turbocharged monsters based on today's variants, everything seemingly is on the table. Whether Detroit's Big Three could have foreseen the modern muscle car wars escalating so much when the Camaro and Challenger were reintroduced back in 2009 remains dubious but there's no doubt the renaissance is still going strong. Of course, the original muscle car era culminated in legends like the Plymouth Superbird and Dodge Charger Daytona, so somebody had to go ahead and build a new variant like this 2009 Dodge Challenger-based Plymouth Superbird prototype built by Heide Performance Products of Washington Township, Michigan, with a little help from none other than Petty's Garage.

The car just popped up on the auction website Bring a Trailer with some photos and videos documenting the radical build. While the exterior wing and nose-cone hark back to the original Superbird, under the hood, the 5.7-liter Hemi V8 benefits from a Magnuson supercharger and is paired to a six-speed manual transmission.

Two-Tone Interior

The interior styling matches the exterior, with orange seat inserts and matching accents on the dash, steering wheel, and Pistol Grip shifter. Over 30,000 miles have been logged on the car, an impressive feat made all the more impressive by the fact that a testing video shows the car eclipsing 2012 miles per hour—despite retaining a 160-mile-per-hour speedometer.

Plenty of Plymouth and Superbird graphics adorn the car—as if anyone couldn't spot the resemblance from a mile away—while louvers for the rear window have also been added. Those side scoops are non-functional, though pop-up headlights have been fitted in the nose. The only real questions remaining about this car are why HPP and Petty's Garage didn't build it up in the style of a Dodge Charger Daytona and how high bidding will climb in the seven days until the auction closes.
