The concept is fitted with a new turbocharged 2.0-liter four-cylinder engine that is currently under development

Toyota surprised visitors at the 2025 Tokyo Auto Salon on Friday with a GR Yaris prototype featuring a new 2.0-liter turbo-4 engine in a mid-engined layout. Toyota stated that the prototype is part of a collection of test vehicles engineers are using to develop what the automaker describes as “ ever-better motorsports-bred cars .”

This GR Yaris will compete in Japan’s S-Taikyu racing series. The company plans to torture test the vehicle to see what breaks.

Toyota's Gazoo Racing wing has been on a roll for the last few years, bringing us the likes of the revived Supra (with the help of BMW), the upgraded GR 86 (with the help of Subaru), and the rally-ready GR Yaris and GR Corolla (all by themselves).

Toyota has pulled out all the stops at this year’s Tokyo Auto Salon, unveiling three striking examples of its GR Yaris hot hatch under the banner of ‘Car-making at Nürburgring’. These include a competition test and research prototype designed to extend the car’s potential on road and track.
