A more powerful Toyota Supra has long been the subject of rumors since the reappearance of the 2020 model year. Of course, this happened for 2021, but it is not a high-end performance model. Toyota has upgraded the Supra 3.0 to 382 horsepower (285 kW), but a new rumor attributes to an upcoming GRMN model more than 500 ponies.
This rumor comes from the Japanese site bestcarweb.jp, who claims to have an inner scoop. In short, the claim is that Toyota will equip the boosted six-cylinder in-line of the BMW M3 / M4 under the hood of the Supra, where it will generate the same 510 horsepower and more than the Bimmer competition models. The shifting functions will also be pure BMW with a seven-speed DCT transmitting power to the rear wheels. If the rumor is true, it would make an Supra extremely fast.
But the rumor doesn’t stop there. The report suggests that at least some of this information came directly from the boss of Supra Tetsuya Tada, and that BMW was apparently not very keen on giving Toyota the M-infused engine. This may be a factor another aspect of the rumor, which says that this M-powered Supra GRMN will be launched in 2023 with only 200 units slated for production. Such a low figure would certainly make this Supra less of a threat to BMW sales. But wait, there is more.
This protracted rumor also puts an end to life on the Supra. The report says the car will cease production after 2025 and that no replacement is in progress. In fact, this Supra GRMN could serve as the final edition of the car, sold alongside the standard six- and four-cylinder models to conclude production of the sports car.
The final part of the rumor suggests a price for the Supra GRMN, and if you’ve ever been blown away by what we’ve reported so far, you may want to sit down. A figure of 12 million yen has been dropped, which currently translates to about $ 112,000 in US currency. We must emphasize that the report only offers this as a suggestion, but it is a wild suggestion in the middle of a history of wild claims.
At the end of the day, we advise readers to take it with a grain of salt. Yes, a Supra GRMN should expire, but the same source reported a Supra GRMN in January which would be launched this year with around 400 horsepower. If Tada-San did disclose information for this latest report, that gives the rumor a little more credibility. In the end, we will simply have to wait for more information – officially or unofficially from other sources – to be available.
