As we continue knowing basically nothing about Toyota and BMW's magical hybrid sports car partnership, there is one possibility we can probably rule out: a hybrid version of the Toyota GT86, aka Scion FR-S and sometimes the Subaru BRZ.
The UK's Autocar reports that Toyota as of late is downplaying the idea of a hybrid GT86. Toyota Europe's marketing director Fabio Capano said it's probably not what "the majority" wants and also hard to make a substantial business case for.
The costs for this would be considerable, and European GT86 sales have not been nearly as strong as they have been in the U.S.
We do know that GT86 chief engineer Tetsuya Tada at one point said Toyota explored the possibility of a hybrid drivetrain to boost power, as well as forced induction. None of those things have happened yet.
I'm not opposed to the idea of an affordable, high-performance hybrid sports car that gets good mileage — that idea is considerably less ridiculous than it used to be — but I'd just as well leave the GT86 alone. We'll have to wait and see what BMW and Toyota are cooking up instead.
