Toyota's GR Yaris M Prototype Set for Track Testing This Weekend
Written with artificial intelligence.
Toyota's GR Yaris M prototype has shifted from a sporty compact to a coupe design as it heads for testing at the Okayama circuit during the Super Taikyu championship. This new iteration allows Toyota to refine its central engine layout while assessing performance components.
New Prototype Design
Toyota's mysterious central-engine sports car, previously known as the GR Yaris M, has undergone a significant transformation into a coupe for its upcoming testing sessions. Although the design has changed, it does not necessarily reflect the final production model. Recent images shared by Ogura Racing Clutch show the prototype undergoing circuit tests, retaining familiar elements like the headlights and taillights from the GR Yaris, indicating that some components are being repurposed.
Testing Focus
The prototype features angular fender flares designed to accommodate the cooling systems required for the centrally mounted engine. These additions suggest that the design is still in the experimental phase rather than being a final production model. The overall silhouette hints at Toyota's vision for a sports car, but details remain fluid as development continues.
Technical Developments
Toyota introduced the GR Yaris M concept at the 2025 Tokyo Auto Salon, shifting the engine from the front to a mid-engine layout. This change significantly alters weight distribution and mechanical setup. The prototype aims to test the engine, cooling systems, transmission, and chassis without committing to a finalized exterior design, which is crucial for a central-engine vehicle that faces unique engineering challenges.
Upcoming Track Events
The GR Yaris M coupe prototype is scheduled to return to the track during the sixth round of the Japanese Super Taikyu championship at Okayama International Circuit from October 23 to 25. The GR Team ORC Field will participate in the experimental ST-Q category, providing valuable data for the ongoing development.
Future Prospects
Toyota is developing a new G20E 2.0-liter turbocharged four-cylinder engine, aiming for over 400 hp in a future production model. While the prototype is still in testing and far from final production, it hints at the potential reintroduction of the MR2 nameplate, which has been absent for years. With ongoing developments, anticipation grows for what Toyota will ultimately deliver with this central-engine sports car.
