The Mid-Engine GR Yaris Exists, and It’s Hiding Toyota’s Next Sports CarFor years, the automotive industry has been chasing rumors of a Toyota MR2 revival. While concepts like the electric FT-Se gave us a glimpse of the future, purists have been holding out for a true internal-combustion, mid-engine sports car. Thanks to recent sightings at Fuji Speedway and a semi-secret test session at Toyota's Shimoyama facility, we finally have concrete proof that Gazoo Racing is building exactly that.Recent footage out of Japan shows a heavily modified GR Yaris tearing around the track. But this isn't just a standard hot hatch with a body kit. The prototype features a lowered roofline, a swan-neck wing, and massive vertical intakes on the rear fenders, confirming a rear-midship layout.The 400-Horsepower G20E EngineThe real star of this test mule is what's sitting behind the driver. According to reports from Best Car and other Japanese outlets, this prototype is testing Toyota's brand-new G20E 2.0-liter turbocharged four-cylinder engine.AdvertisementAdvertisementThis next-generation powertrain is an absolute monster. While it is physically 10 percent smaller than Toyota's current 2.4-liter turbo, it packs significantly more punch. Road-going versions are expected to produce roughly 400 horsepower, while racing applications could push nearly 600 horsepower. When paired with the GR-Four all-wheel-drive system, this mid-engine setup completely transforms the vehicle's dynamics.During a passenger ride-along at the Shimoyama test facility, Carnow noted that this "M Concept" mule feels entirely different from a standard GR Yaris, displaying a sharp, rear-wheel-drive bias that rotates the car from just behind the front seats.Toyota hasn't officially confirmed what production car this platform will become, but the writing is on the wall. Late last year, the automaker officially trademarked the "GR MR2" and "GR MR-S" monikers.Given that the G20E engine was explicitly designed for high-performance sports cars, and Gazoo Racing is actively refining a bespoke mid-engine AWD chassis, this Frankenstein Yaris is serving as the mechanical foundation for Toyota's next legendary coupe. While a production model might still be a few years away, the fact that a 400-horsepower, mid-engine Toyota is actively burning rubber in Japan is incredible news for enthusiasts.
