"Corroborating earlier reports, an unnamed German source has told Car and Driver that Toyota will build a bigger model than the next-gen Z4, powered by a BMW-sourced turbocharged inline-six engine rather than the four-cylinder engine that will likely be found under the hood of BMW's roadster.
Toyota is allegedly planning to revive the Supra nameplate, making the inline-six a suitable choice to maintain consistency with the retired generations. Styling is expected to be inspire by the FT-1 concept car (pictured) that was introduced last year in Detroit."
"Toyota has decided to drop the hybrid drivetrain in favor of a BMW-sourced turbocharged inline-six. And it gets even better: the Supra’s rear-wheel-drive chassis will be developed mainly by BMW, too. So what exactly will Toyota bring to the table?"
