Toyota's V8 Supercars engine, a powerhouse in the making, has been unveiled by the UK-based firm Swindon. The engine, a 5.2-liter quad-cam 2UR-GSE, is an all-aluminium marvel, designed to fit within the 5.0 to 5.7-liter window mandated by Supercars. Swindon, under the leadership of Raphaël Cailléat, has been instrumental in its development, simulation, and production, with a keen focus on the crank train and valvetrain hardware. The engine boasts a square 94x94 bore and stroke, promising a competitive and durable power unit capable of achieving 600bhp. This isn't Swindon's first foray into Supercars; their previous collaboration with Triple Eight and Sodemo in the 2004 V8 engine project, though ill-fated, laid the groundwork for their current expertise. The Supra engine incorporates OE parts like the cylinder head, block, main caps, timing chain, and followers, along with hydraulic variable valve timing (VVT) and a 3D-printed inlet tract. The final assembly and ongoing servicing of the race engines will be handled by Walkinshaw at its Clayton, Victoria facility. Despite concerns over performance and readiness for the 2026 season, Swindon's engine is set to challenge established engine producers in the competitive Supercars championship. With five Supras set to contest the championship, including two from Walkinshaw TWG and three from customer team Brad Jones Racing, the stage is set for an intense battle on the track. As the project progresses, Swindon and Walkinshaw are working tirelessly to ensure the engine's performance and readiness for the upcoming season, with track testing and dyno runs already underway. The collaboration between Swindon and Toyota, facilitated by Carl Faux, has been a testament to the power of teamwork, despite the challenges posed by time zone differences. As the season unfolds, all eyes will be on the Toyota Supra, ready to face its rivals in Bathurst, Ipswich parity tests and beyond.
