Aside from the new LED headlights, this latest prototype is wearing the same amount of camouflage as the vehicle spotted doing cold weather testing in March.
If you're worried about the headlights' sunken look, and the un-Toyota-like panel gaps, the prototype has false body panels covering up the contours and details of the production body work underneath.
Under the skin, the new Supra shares its front-engine, rear-wheel drive platform with the next-generation BMW Z4. It's understood the BMW will be sold exclusively as a soft-top convertible, while the Supra will be its fixed roof counterpart.
Spy photos indicate the Supra's interior is largely made up of components from BMW's parts bin, with prototypes fitted with BMW's familiar iDrive control knob, gear shift lever, air-conditioning controls, steering wheel, and infotainment screen.
It's unclear which engines will provide motivation for the new Supra and Z4 twins, although turbocharged four- and six-cylinder motors are highly tipped. Given Toyota's strong hybrid heritage, a petrol-electric variant is heavily rumoured for the Supra.
Launch timing for both models isn't known yet, but BMW has teased a roadster it will unveil at this month's Pebble Beach Concours D'Elegance. This car seems likely to be a concept previewing the new Z4.
If that proves to be the case, the Z4 will probably be launched in 2018, with the Supra following a few months later.
