As revealed by Speedcafe last year<\/a>, Swindon was appointed engine partner for the project by Toyota\u2019s Supercars homologation team that is now known as Walkinshaw TWG Racing.<\/p>\n

The connection came through Walkinshaw team principal and Gen3 Toyota project architect Carl Faux, who previously worked with Swindon boss Rapha\u00ebl Caill\u00e9\u00a0at Triple Eight in the UK.<\/p>\n

Toyota is using a 5.2-litre version of its all-aluminium, quad-cam 2UR-GSE for the Supra<\/a>, having been required to fit within a 5.0 to 5.7-litre window by Supercars.<\/p>\n

\u201cThe engine\u2019s architecture, such as its square 94\u00d794 [bore and stroke], offers a great base for a competitive and durable power unit to achieve 600bhp,\u201d said Caill\u00e9.<\/p>\n

Swindon has led the development, simulation and production of development engines for the project, with a focus on the crank train and valvetrain hardware.<\/p>\n

OE parts used include the cylinder head, block, main caps, timing chain and followers. The Supra engine also runs hydraulic variable valve timing (VVT) and a 3D-printed inlet tract.<\/p>\n

Final assembly and ongoing servicing of the race engines will be undertaken by Walkinshaw at its facility in Clayton, Victoria.<\/p>\n

Swindon\u2019s spruiking of the engine comes amid swirling questions over its performance and readiness for the 2026 season<\/a>.<\/p>\n

Five Supras are set to contest the championship \u2013 two from Walkinshaw TWG and three from customer team Brad Jones Racing \u2013 which begins on February 20-22.<\/p>\n

Jones revealed earlier this week his team currently only has a \u2018dummy\u2019 engine available<\/a> for use as it works towards completing the build of its cars, pointing to tight timelines on the project.<\/p>\n

Track testing of Walkinshaw\u2019s first Supra fitted with a mule engine began last September, while Supercars has had a \u201cproduction version\u201d running on its dyno in recent weeks.<\/p>\n

Supercars motorsport boss Tim Edwards has downplayed concerns over balancing performance with the incumbents<\/a>, noting the Toyota\u2019s similar architecture to Ford\u2019s Coyote V8.<\/p>\n

While the Supercars schedule involves around five times the mileage as the BTCC, Caill\u00e9 said Swindon is not underestimating the challenge of the Australian series.<\/p>\n

Toyota to face rivals in Bathurst, Ipswich parity tests<\/a><\/p>\n

\u201cIt\u2019s been a fantastic collaboration: the time zone difference enabled us to work around the clock, in effect,\u201d said Caill\u00e9.<\/p>\n

\u201cHowever, we don\u2019t underestimate the challenge. Supercars is a competitive championship with established engine producers with experience of the Gen3 regulations.<\/p>\n

\u201cWe respect the job they are doing and now it\u2019s up to us to learn, develop and bring our best efforts to the track. We won\u2019t be satisfied until we start winning.\u201d<\/p>\n

Walkinshaw is due to shake down its second Supra on Monday at Queensland Raceway, where Supercars will also have a Mustang and Camaro on track for comparison.<\/a><\/p>\n

Caill\u00e9 attended the Townsville 500 last July, while Swindon will have Sylvain Rubio trackside for the opening events of the 2026 season.<\/p>\n

The Toyota project is not Caill\u00e9\u2019s first brush with Supercars. His time at Triple Eight included involvement in the ill-fated 2004 V8 engine project run in conjunction with French firm Sodemo.<\/p>\n

Swindon\u2019s current motorsport projects include the 2025-title winning Hyundai BTCC engine, while its design, simulation and manufacturing capabilities also stretch across various automotive applications.<\/p>\n
