An earlier rumor predicted that the Toyota GR86 was in line to receive the turbocharged three-cylinder engine from the GR Corolla, but a new report from Japanese publication Magazine X claims it will spawn a hotter 86 GRMN variant that will remain normally aspirated. For those who have just become familiar with Toyota's Gazoo Racing sub-brand, the GRMN (Gazoo Racing Meister of Nurburgring) models are the most hardcore versions and have never been sold in the United States to date.

The GRMN86 would be a lightweight, limited edition track special of the GR86. It will likely receive a sporty body kit, aero, stiffer suspension, a more aggressive wheel and tire setup, and possibly even a new steering setup.

What's less clear is what will happen under the hood.

The standard GR86 uses a Subaru-developed 2.4-liter boxer four-cylinder engine producing 228 horsepower. Subaru builds a turbocharged version of this engine for the WRX with 271 hp, though it seems unlikely this motor would make its way into the GR86. Rumors suggest the car will keep the normally aspirated setup, but increase the power slightly. This sounds similar to the previous-generation Subaru BRZ tS, which received handling upgrades with no power increase.

We're sorry to burst anyone's bubble who was hoping for a 300-hp GR86 with the GR Corolla's three-pot, but that would require a ton of engineering that doesn't make much sense for a low-volume product.

Instead, a slight power increase seems far more feasible, and it wouldn't encroach on the GR Supra.

With this news coming out of a Japanese magazine, it's unclear whether or not a GRMN86 would be offered outside Toyota's home country, if it gets built at all.

Toyota has already given the US a special edition GR86, but it basically consists of special orange paint and some wheels. The company's last GMRN product, the GRMN Yaris, was limited to only 500 units and was not offered outside of Japan.
