Folks at Toyota and BMW are being very vocal about the new Supra and Z4 being very different machines, despite them sharing the same platform and powertrains. Adrian Van Hooydonk, Design Director for Bimmer, says that the collaboration essentially came down to a single conversation with his counterpart at Toyota.

"He’s Japanese and I’m Dutch, but we immediately understood each other in terms of what we want from our engineers, and in proportions. That was one conversation, that’s all it took. We immediately agreed on the hard points and what we want in terms of proportions," Van Hooydonk told Top Gear. He said that the two teams didn't reconvene until the design process was complete.
According to a previous report, the engineering teams from BMW and Toyota worked together for about two years to determine the right wheelbase, width, fuel tank location, and A-pillar placement. The crews completed this undertaking in mid-2014, and then went their separate ways.
The revied Supra will make its long-awaited debut at the North American International Auto Show in January. Several leaks make the official details seem like a foregone conclusion, though. There are two BMW-sourced powertrain options coming to the United States – a 2.0-liter turbocharged four-cylinder and a 3.0-liter turbocharged inline-six. The only available gearbox is an eight-speed automatic Sales start in the first half of 2019. At some point, Toyota's Gazoo Racing performance division also might create a hotter version, too.
Meanwhile, production of the BMW Z4 is already underway at Magna Steyr's facility in Austria. Sales in the United States start in March 2019, and buyers can get the same 2.0-liter four-cylinder and 3.0-liter inline-six as in the Supra.
