^still that pic too would seem to me as a piece fo hardware way to expensive for a ~$60k car.
And the supra having a different drivetrain layout than the z4 seems very very complicated and cumbersome to make within 1 platform, having to need different subframes and the lot.
Possible... sure, but imo unlikely for a car/platform that has been struggeling for money for 5 years or so where multiple manufacturers had to team up to get a sufficient potential customer base. Usually that screams partsbin (certainly in this day and age of multimarket universal platforms) and not extensive development of custom tech.
But it would be quite a stunt if bmw/toyota could pull something like this.
