A limited edition Toyota Supra with BMW M Power is coming to showrooms in 2023, according to a report by Japan’s Best Car magazine citing unnamed sources.
In a move that further cements the joint venture sports car program between the Japanese and German companies, BMW has reportedly been persuaded by Toyota to use one of its most prized engines in a limited run of Supra coupes.
The special edition is expected to be called the Toyota Supra GRMN (rather than simply GR as per today’s model), a reference to ultra top-end models in the Japanese brand’s performances-car range.
A translation of the Best Car report says the Toyota Supra GRMN will be powered by an uprated version of the twin turbo 3.0-litre inline six-cylinder engine slated for the next generation BMW M3 sedan and M4 coupe.
The report claims the engine will have an epic peak output equivalent to about 382kW/608Nm and be backed by a high-performance, seven-speed dual-clutch automatic transmission.
Today’s Toyota Supra is powered by a single turbo 3.0-litre inline six-cylinder engine (250kW/500Nm) sourced from BMW and matched to an eight-speed torque converter automatic sending drive to the rear wheels. In that guise, the Toyota Supra has a claimed 0 to 100kmh time of 4.4 seconds.
Before the M Power engine arrives in the Supra, an uprated version of the current single turbo 3.0-litre inline six-cylinder engine in the Toyota Supra is due at the end of this year with 285kW but the same 500Nm output.
By comparison, the peak outputs of the recently superseded BMW M3 sedan and M4 coupe from the pair's twin turbo 3.0-litre inline six-cylinder engine are 331kW and 550Nm. In that guise, the BMW M3 and M4 have a claimed 0 to 100kmh time of 4.0 seconds.
The Best Car report claims just 200 examples of the Toyota Supra GRMN will be produced in 2023 as an exclamation point for the model, before it ends production in 2025 – and won’t be replaced.
“It was decided that the Supra GRMN, which will be introduced in 2023 in a limited number of 200, will be equipped with an inline six-cylinder 3.0-litre turbo that will be installed in the (upcoming BMW) M3/M4,” a translated version of the Best Car report said.
“The performance has been further improved for the next (BMW) M4, and the maximum output for the Supra GRMN is 520ps and the maximum torque is 62kgm (382kW/608Nm),” the report continued, adding it would be matched to the high performance seven-speed dual clutch auto.
“It was said that the BMW side initially showed difficulty in supplying this powertrain to Toyota, but (Supra chief engineer) Tetsuya Tada said that it was achieved.”
Best Car also claims BMW has “no plan to install this M unit on the BMW Z4, which was developed in parallel”.
“On the BMW side, it seems that the aim is to utilise this performance with the new M3/M4 with a closed body instead of the open Z4,” the Best Car report said. “There is also information that (the) Supra will complete its model life in 2025 and that there will be no next model.”
The report ended with speculation the Toyota Supra GRMN “will appear at least in 2023”, be “the final edition of the current Supra” and could cost “12 million yen” ($AU162,000).
