It’s been a (very, very) long time in the making, but we finally have our first look at Toyota’s next-generation Supra through an actual prototype, with our spies even catching a glimpse of its interior.

It took Toyota a full decade after the demise of the fourth-generation Supra, codenamed A80, at the end of 2002, to announce a successor in 2012, when it revealed that it had teamed up with the BMW Group to co-develop a pair of sports cars.

Few details were released at the time, but we’ve since learned that the reborn Toyota Supra will be related to BMW’s Z4 successor, slated to be called Z5, with both models be built by the Canadian-owned Magna Steyr operation near Graz.

These spy shots of the new Supra, as well as of the Z5, confirm that the two cars will not only look completely different, but will have different body-styles as well, with the Toyota being a coupe, and the BMW, a soft-top roadster (unlike today’s Z4 that employs a pricier and heavier retractable hardtop).

Keeping in mind that the prototype pictured here is employing non-production front and rear end parts and panels, the new Supra looks closer related to the Toyota 86 than to the 2014 FT-1 Concept, which was believed at the time to heavily influence the design of Toyota’s coupe. Nevertheless, it has a far more aggressive stance with a more elongated bonnet and stubby rear than Toyota’s entry-level rear-wheel drive sports car.

We’re unsure how much of the interior bits are production ready, but while the (backlit?) instrument panel gauges do look very Toyota-like, the air-conditioning controls on the center stack and the steering wheel give us a BMW-kind of vibe.

Whereas the new Toyota Supra and BMW Z5 will wear different costumes on the outside, they’re going to share many components under the skin, including a new platform that takes advantage of BMW’s weight-saving methods, electronic architecture, multilink rear suspension, and possibly even transmissions, albeit with unique settings for each model.

Depending on whom you ask, the two cars may or may not share common gasoline engines driving the rear wheels. Some sources have speculated that the BMW will develop and provide four-cylinder and inline-six turbocharged mills for both cars, with Toyota hybridizing a top-end Supra model with its own electric motors, while others claim that the Japanese carmaker will use a new twin-turbocharged V6 pumping out some 400 horses alongside its own turbocharged four-pots. Toyota and BMW have yet to comment on the matter, but it’s worth mentioning that from what they’ve said up until now, their powertrain partnership involves hybrid systems and diesel engines.

BMW is rumored to roll out the Z5 in the second half of 2017, with Toyota following within the next year.
