A fresh report out of Japan claims Toyota plans to drop the new BMW M3’s engine into the Supra to create a GRMN-badged “final edition”.

According to Japanese publication Best Car, Toyota will end production of the A90-generation Supra in 2025. In 2023, however, the Supra GRMN will appear as a “final edition”, claims the report.

This special Supra, says the publication, will gain the BMW M division’s latest turbocharged 3,0-litre straight-six engine, expected to match the 375 kW output of the Competition-badged versions of the upcoming M3 and M4.

According to the report, Toyota will build just 200 examples of the rear-driven Supra GRMN, sold over the final two years of the generation’s life cycle.

Interestingly, however, BMW has made it clear there are no plans to create a full-fat M version of the Z4 roadster, which was developed alongside the A90 Supra.
