A new test mule recently spotted being put through its paces at Fuji Speedway in Japan has taken the global automotive community by storm, leading many to believe it is a prototype of the upcoming Toyota MR2.
Despite carrying no official branding or camouflage, the mystery vehicle features recognisable Toyota components, including headlights and taillights borrowed directly from the GR Yaris.
Internet detectives have further noted the prominent air vents on the bonnet and large cooling intakes on the rear fenders, suggesting a mid-engine layout. Whilst an unbranded test mule could technically be testing any number of prototype systems, the combination of Toyota parts and a mid-engine setup has led the web to settle on one main candidate, the return of the iconic midship runabout two-seater.
If the test mule is indeed a prototype of the Toyota MR2, this marks the first time Toyota is testing with a body shell that hints at an exterior design similar to the Toyota FT-Se Concept.
Previously, Toyota revealed the GR Yaris M Concept alongside an unnamed prototype undergoing tests for the 2027 World Rally Championship. Whilst the rally prototype remains unconfirmed, the GR Yaris M Concept is powered by a new 2.0-litre turbocharged four-cylinder engine known as the G20E.

The G20E is expected to be the centrepiece of this purported all-new MR2. Designed to be compatible with hybrid applications, the engine can be mounted either longitudinally or transversely. Target outputs for the new mill stand at 400 hp and 500 Nm without hybrid assistance, though engineers reportedly state that a larger turbocharger could push output to 600 hp.
It remains to be seen what the test mule will evolve into. Frankly, almost anything could be hiding beneath the prototype skin, and its true identity is likely known only to a select few within Toyota. Whatever lies beneath, it is not often we get to see a mystery prototype hooning about on a racetrack.
