The next-generation models of the BMW Z4 and Toyota Supra have been joined at the hip ever since BMW and Toyota announced plans to build them together. It’s only fitting; then, that one week before the Z4 finally breaks cover at the Pebble Beach Concours d’Elegance, we get our hands on a spy video of the Z4 and Supra prototypes testing at the Nurburgring together. Who knew that all the hype and pandemonium surrounding these two sports cars would all lead up to seeing them together in the tail end of their respective testing sessions?

It’s all come down to this. After years of constant teasing, speculation, more teasing, and more speculation. The BMW Z4 and the Toyota Supra are finally getting ready to make their world debuts. The next-generation Supra “technically” made its debut at last month’s Goodwood Festival of Speed, but in true Toyota fashion, the sports car that showed up still wore heavy camouflage, preventing us from seeing it in all its glory.

That won’t be the case, though, when the BMW Z4 shows up at the Pebble Beach Concours d’Elegance later this month. Leaked photos of the roadster have already surfaced a week before its much-hyped debut so it looks like everything’s in place for the Z4 to finally show itself to the public after years of seemingly endless stages of research and development.

But before any of that happens, an eagle-eyed spy photographer managed to capture the Z4 and the Supra doing some test runs at the Nurburgring. The video focuses more on the Z4, specifically different prototypes of the same roadster. That’s a hint that we could be looking at different versions of the new sports car, including one with round exhaust tips that we believe to be the sDrive30i. There are also shots of a Z4 with bigger-looking exhausts, which we think is the range-topping, six-cylinder M40i, the same version that was the subject of the aforementioned leaked photos of the Z4 sporting no camouflage on its body.

For its part, the Toyota Supra also appears in the video, looking no less confusing than ever. The sports car’s overall shape follows what Toyota presented with the FT-1 Concept back in 2014, but there are still some notable changes to be expected when the final production model finally breaks cover. Unfortunately, Toyota has not set a specific timetable for the Supra’s debut. But with 2018 already close to hitting its last quarter, don’t be surprised if Toyota brings its headliner to one of the last auto shows of the year. It’s not going to be the Tokyo Motor Show because there won’t be one this year, but what about the Paris Motor Show in October or the Los Angeles Auto Show in December?

Cross your fingers that it happens this year. The BMW Z4 is a week away from making its debut, and if the two sports cars really are joined at the hip, the Supra’s debut could be coming sooner than later.
