The 2023 Toyota Supra GRMN is said to be powered by the same engine as the BMW M4, opening the door for an optional manual transmission.
A high-performance version of the Toyota Supra could eventually become available with the option of a manual transmission, according to respected Japanese publication Mag X.
The Toyota Supra GRMN is expected to be powered by the 3.0-litre twin-turbo six-cylinder engine from the upcoming BMW M3 sedan and M4 coupe, which is said to be available with a high-performance eight-speed auto, or a six-speed manual gearbox.
Power from the BMW M3/M4 engine is expected to be 353kW/600Nm, but rumours out of Japan claim the limited-production Toyota Supra GRMN could have a higher output of 382kW/608Nm.
With the Supra sharing its platform with the BMW Z4 roadster, the powertrain would be an easy swap for a GRMN version of the Toyota Supra – with the badge denoting the highest performance level expected.
Though the Supra isn't currently offered with a manual, BMW provides the option of a manual transmission in the Z4 sDrive20i M Sport.
It's understood Toyota will be providing regular updates to the Supra in an effort to keep the model from becoming stale.
With a power bump already planned for 2021, a two-year update cycle would align the GRMN model for a 2023 release.
