Toyota's V8 Supercars engine is a powerhouse in the making, thanks to the collaboration with UK firm Swindon. The engine, a 5.2-liter version of Toyota's all-aluminum, quad-cam 2UR-GSE, is designed to fit within a 5.0 to 5.7-liter window by Supercars. Swindon has led the development, simulation, and production of the engine, focusing on the crank train and valvetrain hardware. The engine features a square 94x94 bore and stroke, offering a competitive and durable power unit capable of achieving 600bhp. This is a bold move by Toyota, as the engine's performance and readiness for the 2026 season are under scrutiny. Five Supras will contest the championship, with two from Walkinshaw TWG and three from customer team Brad Jones Racing. However, the team's current 'dummy' engine availability highlights tight timelines and potential challenges. Despite concerns, Supercars motorsport boss Tim Edwards downplays the issue, noting the engine's similar architecture to Ford's Coyote V8. Swindon's involvement in the project is significant, as it has a history of working with established engine producers and has experience with the Gen3 regulations. The collaboration between Toyota and Swindon is a testament to their commitment to bringing their best efforts to the track. The engine's final assembly and ongoing servicing will be undertaken by Walkinshaw at its facility in Clayton, Victoria. As the project progresses, Swindon will have Sylvain Rubio trackside for the opening events of the 2026 season, and Caillé will continue to oversee the development and testing of the engine.
