We all know that BMW and Toyota have been working together on a joint sports car chassis that will spawn the BMW Z4 and Toyota Supra successors. We know that both cars will share technology, chassis components and maybe even some powertrain bits. However, they won’t be identical twins, as both cars will look considerably different and both cars will have different clientele bases. But, despite their differences, both cars went winter testing in the snow together and we’ve found some spy video.

In the video, we first see the Toyota Supra having some slidey fun in the snow. Its shape looks good from what we can tell, even though it might have some fake body cladding to throw us off. Though, the overall profile of the car looks very cool, with its incredibly short rear deck, duck-tail spoiler and long hood. It has a very classic sports car profile and we like it.

We also get to hear its exhaust note pretty clearly. It sounds nice, with a sort of raspy six-cylinder sound. We don’t know for sure what sort of engine will be powering the Supra, whether or not it will be a Toyota V6 or BMW I6, but either way it sounds good.

Toward the end of the video, we also see the upcoming BMW Z4 doing some snow drifts. We’ve already seen a lot of spy photos of the new Z4, so this view isn’t anything new. However, it’s good to note that its classic roadster proportions are in tact. Its rear deck is a bit longer than on the Supra, but it has to be to fit the folding roof, so it’s obvious that these two cars won’t be identical twins, like the Toyota GT86 and Subaru BR-Z. We can also hear the Z4’s exhaust, which sounds considerably different than the Supra’s. This could mean it uses a different engine entirely or just that BMW and Toyota will tune the exhaust differently. But the Z4 definitely had a more growly, more refined sound than the Supra.

We can’t wait for both cars and this video just gets us more excited.
