The GR Yaris M Concept is a testbed with troubles
Toyota’s GR Yaris M Concept, a testbed for the company’s compact mid-engine sports car engineering, has yet to make its planned 2025 race debut as the manufacturer grapples with significant developmental challenges. After the GR Yaris M Concept missed another race in Japan’s Super Taikyu Series this past weekend, Toyota announced: “While many challenges have been identified and improvements are ongoing, there are difficulties unique to midship-mounted vehicles in terms of braking, steering, and driving, and Toyota has therefore decided not to participate with this vehicle at Autopolis to refine it further.” Toyota added that it “has its sights set on entering the vehicle in future races,” but there are only two more Super Taikyu Series rounds left in the 2025 season. The Super Taikyu Series consists of seven rounds, with its final two races scheduled to take place over a three-hour event on October 26 at Okayama International Circuit and November 16-17 at Fuji Speedway. Toyota unveiled its GR Yaris M Concept in January. According to the manufacturer, the GR Yaris M Concept features a new G20E engine with an IHI turbocharger, producing 400 to 450 standard horsepower. A version with a larger turbo is also available, offering up to 600 horsepower.

Mid-engine sports car challenges aren’t limited to Toyota
Mid-engine sports car development issues have occurred with other automakers, such as General Motors (GM), which encountered several problems with its Pontiac Fiero produced during the mid-1980s. The Fiero sports car used a three-quart oil pan instead of a four-quart one during its first model year, resulting in the engine sometimes running hot due to an oil shortage, according to MotorTrend. Pontiac’s 1984 Fiero also had weak connecting rods and a wiring harness mounted too close to the exhaust manifolds, which increased the risk of engine fire. One in every 400 debut Fieros experienced a fire, and GM didn’t recall the vehicle until 1987.
So, what makes a mid-engine car difficult to perfect? These vehicles have a low center of gravity, which aids stability but makes regaining control harder during spins. Mid-engine sports cars are also more expensive on average to make, posing challenges to companies like Toyota. In contrast, companies like Ferrari, known for using this configuration, aren’t as restricted in this area. Since mid-engine parts are more difficult to access, repairs can also come at a higher expense. Rumors of Toyota using the GR Yaris M to help revive its mid-engine MR2 sports car have excited many, but this concept’s slow development raises doubts about a near-future MR2 release.

Final thoughts
Toyota hasn’t yet pulled the plug on its mid-engine sports car testbed, but those waiting on an MR2 revival shouldn’t necessarily hold their breath. The automaker has until mid-November to fulfill its goal of entering the GR Yaris M Concept into Japan’s Super Taikyu Series, and whether this happens will likely influence release timelines for future mid-engine models. Toyota’s current struggles with its compact mid-engine sports car concept underscore the challenge of striking a balance among performance, reliability, and affordability in these vehicles. Still, the manufacturer appears to be carefully navigating these obstacles to facilitate smooth debuts of future mass-market models using the configuration.
