Apparently, this rumor was started by Tetsuya Tada — chief engineer on the Scion FR-S program – during his interview with Asia One. According to Tada, Toyota will be offering successors for both the Supra and the MR-2 , with the most expensive one being the one offered first. However, both will arrive in the next five years.
Tetsuya Tada tried to keep quiet on the powertrains used for the two models, but he did indicate that Toyota "will become more experimental." He pointed out that Toyota may be using Tesla to provide a battery-based drivetrain for a new Supra. In fact, the Japanese company is developing a 3-Series competitor that would make use of the same flexible platform found in the Model S.
We’ll find out if the next Supra is going to be offered with an electric powertrain in the upcoming months, so stay tuned!
