The Toyota Supra and its targa-topped variant was one of the coolest cars from the 1990s. The fifth-generation GR Supra remains coupe only but there's now proof the Japanese automaker hasn't forgotten the past. Meet the Toyota GR Supra Sport Top, a one-off homage built for this year's online-only SEMA Show, redubbed SEMA360. This concept is a follow-up to last year's GR Supra Heritage Edition and the team behind it realized a removable roof was the next logical step.

"We had such a great response to the Heritage Edition last year," said Ed Laukes, Group Vice President - Toyota Marketing, "I asked the guys at our Motorsports Garage if we could take the Heritage Edition to the next level and make a Supra with that removable roof everyone remembers from the MKIV?'"

Work on this initially began with an air saw, but that "got nowhere real fast," according to the owner of Texas-based KC's Paint Shop. After just 30 minutes they only managed to cut an inch of steel, so a different cutting tool was used. The targa roof itself consists of two 3D-printed composite panels courtesy of Toyota's Ann Arbor, Michigan R&D center. These panels were contoured to the Supra's body lines while the windshield header and driver's and passenger's side outer roof body structure remained intact.

Structural integrity was maintained thanks to reinforcing the roof's outer body structures. Additional reinforcement can be found on the car's underbody, from the engine bay to the tub's rear. Other one-off components include a hand-built rear diffuser.

MKIV-inspired styling includes round taillights and the rear basket handle wing integrated into the rear decklid. Under the hood lies the familiar 3.0-liter turbocharged inline-six-cylinder though there's an upgraded exhaust and brakes.

Toyota gave no indication whether or not production is being considered, but even a limited number of examples require some level of demand. Pricing is perhaps the most significant factor. Based on what Toyota is telling us, this was a challenging project and the work required to hack off the original tops and 3D print new ones might be too costly. Hopefully, Toyota will gauge customer interest anyway so let your opinions be heard.
