The Toyota V8 Supercars engine has been unveiled, and it's stirring up quite a buzz in the automotive world! But who's behind this powerhouse? A UK-based firm, Swindon, has been unmasked as the secret weapon in Toyota's arsenal.
Last year, Speedcafe broke the news (https://speedcafe.com/supercars-news-toyota-v8-engine-supra-walkinshaw-andretti-united-uk-carl-faux/) that Swindon was chosen as the engine partner for Toyota's ambitious Supercars project. This partnership was facilitated by none other than Carl Faux, Walkinshaw TWG Racing's team principal and Gen3 Toyota project architect. But here's where it gets interesting...
Toyota's Supra is set to roar with a 5.2-liter version of its 2UR-GSE engine, a powerhouse that boasts an all-aluminum, quad-cam design. And this engine has a story to tell. It was specifically tailored to fit within a 5.0 to 5.7-liter window, as mandated by Supercars. Raphaël Caillé, Swindon's boss, revealed the engine's secret sauce: "The engine's architecture, with its square 94×94 bore and stroke, provides an exceptional foundation for a robust and high-performing power unit capable of delivering 600bhp." But the real magic lies in Swindon's expertise.
Swindon has been the mastermind behind the engine's development, simulation, and production, paying meticulous attention to the crank train and valvetrain hardware. They've utilized original equipment (OE) parts, including the cylinder head, block, main caps, timing chain, and followers. But that's not all—the Supra engine also features hydraulic variable valve timing (VVT) and a cutting-edge 3D-printed inlet tract.
As the 2026 season approaches, questions about the engine's performance and readiness are swirling. Swindon is responsible for the final assembly and ongoing maintenance of these race engines, which will be handled by Walkinshaw at their Clayton, Victoria facility. But the pressure is on as five Supras are gearing up to compete in the championship, with two from Walkinshaw TWG and three from Brad Jones Racing, starting on February 20-22.
And this is the part most people miss—the tight timelines and challenges faced by the teams. Brad Jones Racing, for instance, currently has only a 'dummy' engine available as they race against time to complete their cars. Meanwhile, Walkinshaw's Supra, fitted with a mule engine, hit the track for testing last September, and Supercars has been busy running a 'production version' on their dyno.
But is the engine ready for the big leagues? Supercars motorsport boss Tim Edwards has played down concerns about performance parity with the incumbents (https://speedcafe.com/supercars-news-2026-toyota-supra-ford-mustang-chevrolet-camaro-parity-testing-bathurst-ipswich/), drawing parallels between the Toyota's architecture and Ford's Coyote V8. However, the Australian series presents a unique challenge, with Swindon acknowledging the need to adapt to the demands of the Supercars schedule, which covers approximately five times the mileage of the BTCC.
The real test is yet to come, as Toyota gears up for head-to-head parity tests against rivals at Bathurst and Ipswich (https://speedcafe.com/supercars-news-2026-toyota-supra-ford-mustang-chevrolet-camaro-parity-testing-bathurst-ipswich/). Caillé is confident in the collaboration, stating, "The time zone difference allowed us to work around the clock." But he also acknowledges the competition, saying, "We respect the established engine producers with Gen3 experience. It's our turn to learn, evolve, and bring our A-game to the track. We won't settle until we're on top."
As the second Supra from Walkinshaw gets ready for its debut at Queensland Raceway, the stage is set for a thrilling showdown with Mustang and Camaro. With Swindon's Sylvain Rubio trackside for the 2026 season opener, and Caillé's previous involvement in the 2004 V8 engine project with Sodemo, this Toyota endeavor is more than just a race—it's a journey of innovation and determination.
