Toyota GR Supras to race with a 5.2-litre V8 engine
New Supra unveiled in Sydney on Monday night
Toyota has confirmed it will join the Repco Supercars Championship with a 5.2-litre V8 engine.
The Japanese powerhouse will enter the championship in 2026 with two cars from Walkinshaw Andretti United and four from Brad Jones Racing.
The Supra will run with a Supercars version of the quad-cam 2UR-GSE V8, which will be achieved with a square 94×94 (bore and stroke) specification. The engine will also run hydraulic variable valve timing (VVT) and a bespoke inlet manifold.
Speaking at a media call in Sydney, WAU Director Ryan Walkinshaw was clear in his opinion of the engine: “It sounds f***ing good.”
At the time of the initial announcement last year, when asked if a six-cylinder was an option, Toyota Australia Vice President Sales, Marketing and Franchise Operations Sean Hanley quipped it was discussed for "about three minutes" before adding "actually it was probably about one [minute].”
Per Gen3 Supercars regulations, engines must have a capacity between 5.0 and 5.7 litres inclusive. The Ford motor is 5.4L, and the Chevrolet 5.7L.
Following its unveiling in Sydney, the GR Supra Supercar will make its public debut at Mount Panorama, where it will be on display for public viewing and performing demonstration laps as part of this year’s Repco Bathurst 1000 in October, with further activity planned across the remaining rounds of the 2025 Supercars Championship.
Toyota’s Supercar testing program will commence imminently at racetracks throughout Australia, all leading into the important wind tunnel and AVL dyno assessments as parity is finalised in preparation for the opening round of the Repco Supercars Championship in February 2026.
"Getting parts for this car and for our engine has involved a huge amount of work in the background, working with the [Toyota] team here in Australia to try to get those parts from all over the world,” Walkinshaw added.
"To make this engine program come to life was a lot more complicated than we initially thought it was going to be."
