Toyota currently sells the street-legal Supra with four- and six-cylinder engines supplied by BMW. The track-only GT4 variant also uses an inline-six of Bavarian origins. Come 2026 though, the company's Australian branch will shoehorn in a big ol' V-8 developed in-house. A naturally aspirated 5.0-liter engine will power a race car for the Repco Supercars Championship.
