Toyota is reportedly testing a new inline-four engine in a GR86. The engine is said to be a 1.6-liter turbocharged three-cylinder unit, similar to the one found in the GR Yaris.
The GR86, a sports coupe developed in collaboration with Subaru, currently uses a 2.4-liter naturally aspirated boxer engine. The potential shift to a turbocharged inline-four engine could mark a significant change in the vehicle's powertrain strategy.
While details remain limited, the development suggests Toyota may be exploring different engine options for its sports car lineup. It is unclear if this test mule indicates a future production model or is part of broader engine development efforts.
