Watch Toyota Hack the Roof Off a Supra to Create the "Sport Top"

It’s easy to criticize Toyota for choosing the easy way to develop the Supra MkV, and I certainly did it. On the other hand, naysayers like myself are aware that sports cars don’t sell too well in this day and age. Given how much money goes into researching and developing a brand-new model from the ground up, I agree with the compromise that Toyota made.

Be that as it may, the Japanese automaker prepares something very special for die-hard enthusiasts. Dubbed Sport Top, the one-of-one build in the following video serves as a throwback to the 1986.5 model Supra Sport Roof. A departure from the more usual T-tops of that era, the Sport Roof takes a bit of inspiration from the Porsche 911 Targa from the 1960s.

Cutting the roof off is one thing, but the hardest part of the build has yet to unfold. In addition to an open-air cockpit, the white-painted car is rocking a custom stainless-steel exhaust system with center exits. The underbody is where you’ll find a hand-built aerodynamic diffuser that integrates Venturi tunnels. Not long from now, the front end and the sides will also be treated to aero trickery while the rear deck will be complemented by a high-rise wing.

Toyota also intends to switch to a motorsport-style wheel design painted in black, and super-sticky Toyo tires will be fitted on every corner. We don’t know if something’s cooking under the hood, but then again, the GR Supra is pretty fine as is with the B58 straight-six engine from the BMW Z4 M40i.

The 3.0-liter turbo develops 382 horsepower and 368 pound-feet (498 Nm) of torque from the factory, translating to 3.9 seconds to 60 miles per hour (96 kph) and a top speed of 155 mph (250 kph). If we’re lucky, the rumored Supra GRMN may level up to the S58 engine that BMW uses in the M3, M4, X3 M, and X4 M.
