Toyota GR86 Tests New Inline-Four Engine







Toyota's Gazoo Racing division recently showcased an experimental GR86 prototype at the Super Taikyu endurance racing series in Japan, drawing significant attention with its innovative powertrain. This unique vehicle has replaced its previous turbocharged three-cylinder engine with a newly developed naturally aspirated 2.0-liter inline-four unit, signaling a potential shift in the brand's approach to sports car engineering. This new engine, internally codenamed G20E, is part of Toyota's initiative to create a new generation of more compact and lighter four-cylinder engines, which has also been seen in other concept vehicles like the GR Yaris M Concept.
Toyota Explores New Powertrain Options for GR86
At the Okayama International Circuit, automotive enthusiasts and experts alike witnessed Toyota's ambitious strides in engine development. While the spotlight often falls on futuristic concepts, the GR86 Future FR Concept stood out by embracing a naturally aspirated 2.0-liter inline-four engine, a stark contrast to its previous turbocharged configuration and the Subaru-derived boxer engines historically associated with the GR86. This G20E engine, a cornerstone of Toyota's fresh lineup of compact, lightweight four-cylinder powerplants, generates approximately 220 horsepower when installed under the GR86's hood.
Kazuya Oshima, a driver for Gazoo Racing, highlighted the benefits of this new setup, noting the reduced front-end weight due to the absence of a turbocharger. He also praised the engine's higher-than-anticipated rev capabilities and the immediate, predictable throttle response, which is crucial for precision driving, especially when exiting corners. Beyond the engine, this GR86 concept also features a double-wishbone suspension system at both the front and rear, with engineers actively refining various geometric configurations to enhance handling dynamics. Interestingly, this experimental GR86 has earned the internal moniker "Levin" in Japan, a nod to the sporty Corolla variant.
While Toyota has not yet confirmed the powertrain for the upcoming generation of the GR86, this rigorous testing phase suggests a strong possibility that the brand may move away from its long-standing collaboration with Subaru for engine supply. The shift towards an in-house developed inline-four engine could signify Toyota's desire for greater independence in shaping the character and performance of its future sports cars. This evolution could redefine the identity of the GR86, which has carved a niche as an accessible, rear-wheel-drive coupe in an increasingly complex automotive landscape.
This initiative by Toyota underscores a broader trend in the automotive industry where manufacturers are continually seeking innovative solutions to balance performance with efficiency. By developing engines that are smaller, lighter, and more responsive, Toyota is not only pushing the boundaries of its own engineering capabilities but also laying the groundwork for a new era of sports cars that prioritize driving purity and engagement. The long-term implications for the GR86, and indeed for Toyota's entire performance division, are exciting and will be closely watched by enthusiasts globally.
