The new Toyota Supra sports car will be a "very different" car from the BMW Z4 it is being developing alongside, the project's chief engineer has told Autocar.
The road-going version of the Supra is due to arrive in 2019, but has been previewed with a GR Supra Racing Concept at the Geneva motor show.
The new version of the front-engined two-seater is set to be powered by a 335bhp motor. Both the Supra and the Z4 have been spotted testing in camouflage, and BMW has already shown a Z4 concept.
Speaking at the Geneva show, Toyota's European boss, Johan van Zyl, said: "Yes, the Supra is returning. This concept is a clear signal of our intent to bring one of our more iconic sports cars back to the circuit. This is designed for the track and is a thoroughbred race car."
The GR Supra Racing Concept shown at Geneva has been created by the firm's motorsport division, Toyota Gazoo Racing. It is rear-wheel drive, and the firm says "advanced lightweight materials" have been used in its construction, particularly on the large rear wing, front and rear bumpers and diffusers, and side skirts. The windows are made from plastic to save weight.
The road-roading version will launch as a coupé, with different versions likely to follow. Chief engineer Tetsuya Tada, who previously headed engineering for the GT86, told Autocar: "In May 2012, the chairman called me and told me to go to Germany. I wasn't given the mission to create a Supra, I was told to discuss possible developments with BMW. After two years of discussions, we came to the idea of the Supra."
