A report coming out of Japan is claiming that a faster version of the Toyota Supra could premiere before the end of 2020 with up to 395 hp.

Best Car Web says it received word from unspecified sources that a GRMN-badged version of Supra is just around the corner and could arrive soon with a lot of fanfare. We asked a contact in Toyota North America about the rumor, to which they responded that the news on a GRMN Supra, is pure “speculation. We’re not aware of that vehicle”.

Now, before you completely dismiss it, there’s a possibility that both sources are right; Toyota may indeed be readying a GRMN Supra exclusively for Japan and other markets outside North America (at least at this stage) or perhaps it hasn’t been decided yet, hence remaining a rumor.

So, if it happens, what should we expect?

As with other products that have been worked on by Gazoo Racing, this new version of the Supra could shed some pounds thanks to the inclusion of various carbon fiber components.

The real headline of the Toyota Supra GRMN, however, will be the added grunt it could receive thanks to Toyota engineers working their magic on the car’s 3.0-liter turbocharged BMW-sourced six-cylinder engine. In stock form, the car delivers a claimed 335 hp and tuning companies have already developed ECU upgrades that increase grunt to over 400 horses. Toyota could do the same and easily eke out some more power with very little effort.

To complement the engine upgrades, Toyota could also make some suspension adjustments to the car to further improve the handling and ensure it can deal with all the added grunt.

If such a new Toyota Supra variant does hit the market, it will likely do so with a multitude of new exterior parts to differentiate it from the current car. This could include tweaked front and rear bumpers and a potential fixed rear wing.

Last year, Toyota Supra chief engineer Tetsuya Tada said that a new Supra variant could arrive every year. It would make sense if the first of these new versions was a more powerful one.
