The latest leaks follow on from an earlier detailed shot of the Supra's front end, taken when the car was on a transporter, published on forum dedicated to the new car and in our gallery above.
Deliveries of the new sports car will begin soon after the Detroit reveal, Toyota has confirmed, with the first cars due to be seen in the first half of next year.
The Supra name will be back on a Toyota sports car for first time since 2002, development of this model having taken place alongside the new BMW Z4. Development started in 2012 as one of a series of projects between Toyota and BMW.
Power comes from a BMW-sourced 3.0-litre straight-six engine with around 340bhp and 350lb ft. Drive is sent to the rear wheels through an eight-speed ZF automatic transmission.
The Supra, which also features a BMW M Active limited-slip differential, weighs around 1500kg and has a 50:50 weight distribution, its body constructed of a blend of steel and aluminium.
The model's lengthy gestation period has led to a series of leaks and drip-feed of information in the build-up to its hotly anticipated launch. Previous images that surfaced on a parts catalogue site showed three different wheel sizes for three different specs, as well as the availability of turbocharged four-cylinder and six-cylinder engines.

Key detailed elements of the Supra's styling such as the front lights, bumper, dashboard with digital instrument display, rear bumper and splitter were shown separately, giving more hints as to what the car will look like. It also suggested the car will feature the distinctive, script-like Supra logo seen on the previous-generation car.
Chief engineer for the project, Tetsuya Tada, previously told Autocar at the Goodwood Festival of Speed, where the car made its dynamic debut, some of the tech specs of the new model.
“I can’t disclose specific figures, but the output of this engine is on a par with that which we have with the F-Series from Lexus,” Tada said. "The RC-F and GS-F make 389lb ft," he continued, “but you can imagine from seeing it that the car is light and compact – its wheelbase is even shorter than the GT86’s. It’s around 200-300kg lighter than the F-Series [which weighs around 1700-1800kg].”
The Supra's expected 1500kg makes it 250kg heavier than the GT86 and 14kg lighter than the fourth-generation Supra, which went out of production in 2002. This would also make the car 14kg lighter than a PDK-equipped Porsche 911 Carrera S, with which the Supra's expected 0-62mph time of 3.8sec would make it most comparable.
