The company has made no announcement regarding a new hot hatch, but, under the same disguise as prototypes of the recently revealed Supra sports car, the mule looks to be carrying out high-speed performance and handling tests.
The main clue as to the model’s sporting ambitions are found at the rear, where two wide-bore exhaust pipes can be seen exiting a diffuser-style bumper.
Elsewhere, wide alloy wheels wrapped in low-profile tyres round off a low, squat stance in the same vein as the range-topping GRMN variant of the current Yaris.
The next-gen Yaris will move to Toyota’s latest TNGA vehicle architecture, as used by the new Corolla and Camry. That car is tipped for a reveal late next year, suggesting these images show final testing of components for the new model.
