Over the past few years, Toyota has become a go-to brand for enthusiasts looking for accessible performance models. These include models such as the GR Corolla hot hatch, GR86 sports coupe, and the soon-to-be-discontinued GR Supra. Plus, foreign markets get the similarly exciting GR Yaris.Toyota is building on this compelling lineup, at least in Japan, by introducing the two-seater GRMN Corolla and a concept for the GR Corolla Morizo RR, with the company announcing that a production version is coming. As a refresher, Morizo is the nickname for Toyota Chairman Akio Toyoda when he goes racing. The company already uses the moniker in Japan in the high-performance Lexus LBX Morizo RR. Let's take a closer look at the new Corolla concept. The GR Corolla Morizo RR Concept ToyotaToyota is only offering limited details about the Morizo RR version of the GR Corolla at the moment. The automaker describes it as "the ultimate five-seater GR Corolla equipped with GR-DAT [automatic transmission]." The company doesn't have a specific release date for this model yet. The concept will be on display to Toyota fans in Japan at the Fuji Motorsport Forest Welcome Center from June 2 through 28. The automaker previously showed a concept for it at Tokyo Auto Salon earlier in 2026.The two available photos of the vehicle show it wearing the same aggressive body kit as the GRMN Corolla. The parts improve cooling and increase downforce, and the pieces include a vented hood, fender vents, a revised front fascia, and a larger rear wing. This one wears yellow brake calipers that look smaller than the red stoppers on the GRMN Corolla.ToyotaIt's not clear whether the Morizo RR version would share a powertrain with the GRMN Corolla. The vehicle packs an upgraded version of the 1.6-liter turbocharged three-cylinder that makes 300 horsepower and 302 pound-feet of torque – an additional 7 lb-ft over the existing GR Corolla. The engineers tune the powerplant to maximize torque at around 4,000 rpm. The model also features an intercooler spray system to keep things cool during hard driving.The Morizo RR would use Toyota's GR-DAT performance-oriented eight-speed automatic transmission, whereas the new GRMN Corolla has a six-speed manual. The GRMN model also uses an all-wheel-drive system with revised torque distribution settings, new tuning for the electric power steering, and a tweaked suspension with exclusive monotube dampers.With an automatic gearbox and a five-passenger capacity, the Morizo RR could be the ultimate hot hatch for daily driving. The transmission would make stop-and-go traffic more relaxing by not needing to deal with a clutch pedal. Plus, the rear bench means people can fit in the back. The Newly Unveiled GRMN Corolla ToyotaThe new GRMN Corolla is the spiciest flavor of this hot hatch yet. Taking advantage of development at the Nürburgring and in Japan's Super Taikyu endurance racing series, the new model is the most track-focused version yet. One of the most significant weight-saving measures is removing the rear bench seat, leaving just the chairs in front. In all, the rally-inspired machine weighs 3,218.7 pounds, which is 66 pounds less than the existing GR Corolla.A set of Michelin Pilot Sport Cup 2 tires wrap around 18-inch forged wheels. It's not yet clear whether either of these GR Corolla variants would come to the US. However, since the standard model is already available in the country, there's a low barrier to entry to bring them in. If the GRMN Corolla actually comes here, then it would join the short list of two-seat hot hatches ever available in the US, with the other notable example being the Mini Cooper S JCW GP from the early 2000s. CarBuzz Insight – Why This Matters: ToyotaWhile both the GR Corolla Morizo RR and the GRMN Corolla are only being shown in Japan at the moment, we have a good feeling about at least one, if not both, coming to the US. Plus, the two vehicles show that Toyota is continuing to refine the GR Corolla. The company isn't simply launching the hot hatch and then leaving it alone to let competitors overtake the model's performance.Plus, the Morizo RR seems like the exciting daily driver that a more mature enthusiast might be looking for. The weight the rear bench adds wouldn't be noticeable outside of a track, and it makes the car far more practical for family use.
