• Gas Monkey Garage has dropped a 6.2-liter LT4 V8 into the Ferrari.
  • Four rear wheels are now driven by a new drivetrain and transmission.
  • GMG overhauled the supercar’s exterior and added new interior parts.

Some cars age into icons, and some get a third axle bolted on by a Texas TV shop. More than 18 months after the first photo of an otherworldly, six-wheeled Ferrari Testarossa surfaced online, Gas Monkey Garage (GMG) has finally unveiled the finished build. They’re calling it the Ferrari F6, and Maranello is almost certainly not sending a thank-you card.

The path to the reveal was really messy. To make a long story short, Gas Monkey Garage was initially working alongside Danton Art Kustins and Frechy Export LLC to build the Testarossa 6×6, but that relationship fell apart, leaving GMG, founder Richard Rawlings, and partner John Clay Wolfe of ‘GIVE ME THE VIN’ to finish the job on their own. It took a while, but the car is now complete.

A Messy Road To Rosso Corsa

The exterior has moved on from where the build started. The whole car has been laid down in a glistening shade of Rosso Corsa, and custom fixed headlights have taken the place of the originals. While not as cool as the pop-up headlights of the original Testarossa, they still look quite nice. Also visible at the front is a new blacked-out chin spoiler and flared arches.

As you’d imagine, taking an original Testarossa and chopping it up into a six-wheeler is not a weekend job. As the rear now features four wheels and two axles, the bodywork has been completely customized, yet still remains surprisingly faithful to the original car, complete with similar black gills over the taillights and a similar engine cover. Perhaps the most striking addition is a huge rear wing with uprights connected directly to the chassis.

The original Ferrari flat-12 has been ditched in favor of a supercharged 6.2-liter LT4 V8 lifted from a C7 Chevy Corvette Z06. There’s no official word on the exact output, but in standard tune this engine makes 650 hp and 650 lb-ft (881 Nm) of torque. Rather than simply driving the rearmost wheels, the V8 has been hooked up to what GMG calls a custom-engineered “all-wheel drive” system, though in this case, it isn’t truly AWD, since power only reaches the four rear wheels.

Complementing the new engine is a fully independent rear suspension and beefed-up brakes from Wilwood. GMG says the interior has been inspired by the Ferrari F40, and like that car, it has been stripped out. Among the key features are a three-spoke Momo steering wheel, digital instrument cluster, an exposed shifter, and carbon-fiber-backed Recaro bucket seats.

The F6 made its public debut on May 23 via Gas Monkey’s and Wolfe’s YouTube channels, complete with track footage. The build carries a $1.5 million sticker and is being offered for sale. “Can’t wait to see who is ultimately going to take this beauty home,” Wolfe says. Rawlings, for his part, calls it “the best, most boundary-pushing build we’ve ever done.” Maranello is unlikely to agree.
