GENEVA MOTOR SHOW: Toyota Supra is go!

The Toyota Supra is back, or it will be soon.

Toyota went one step short of unveiling the latest iteration of its legendary supercar by showing off the Toyota GR Supra Racing Concept at the Geneva motor show today.

Toyota has committed to reviving the storied Supra nameplate in the near future, and the GR is a clear pointer. Insiders are calling the concept a 'GT' version of the real deal.

Officially, the show car is said to provide a "huge visual clue", bearing a '90' race number on its doors to designate the codename for the fifth-generation model to follow the A40, A60, A70 and A80 Series before it.

Employing lightweight composite materials across body panels including the front and rear bumpers, front splitter and rear diffuser, the racing concept borrows heavily from Toyota's motorsport forays and is said to be a 'GT' version of the production car.

As such, the concept's windscreen and side windows are fashioned from plastic, and the bonnet uses composite materials and features louvered air vents.

"The concept's chassis features lowered front and rear suspension using Toyota components," Toyota says, without divulging any details on the engine or power outputs.

"BBS racing wheels with centre-nut attachment are fitted with Michelin racing tyres. The braking system uses Brembo Racing callipers and discs and there is a racing exhaust."

Inside, the racy theme continues with carbon fibre-lined doors, a racing-style dashboard and OMP driver's seat, quick-released steering wheel and multi-point harness.

The concept's track-ready status is underlined by fitment of a roll cage and fire extinguisher, along with fuel and brake lines, pedal box, battery and wiring looms designed to comply with competition standards.

The big question mark hangs over power. Toyota's recently-unveiled GR Super Sport Concept could provide the strongest portent: a 735kW powertrain comprising a 2.4-litre twin-turbo V6 petrol engine teamed with hybrid motors.

The V6 employs direct injection along with 'lean burn' technologies that will purportedly allow it to deliver ultimate "power and environment performance".

That particular concept was developed by the Japanese firm's Gazoo Racing division, and takes inspiration from the TS050 hybrid race car familiar with the World Endurance Championship.

Alternatively, if recent reports prove true, the Supra will be limited to 250kW inline-six and 145kW four-cylinder turbo-petrol engines and an automatic transmission from BMW.

Either way, the Geneva concept represents another chapter in Toyota's drawn-out development of the Supra co-developed with BMW, which has already revealed its own spin-off, the new Z4.

Toyota Australia's vice-president sales and marketing Sean Hanley was non-committal on when and where the real Supra - the road-going production version - would emerge.

"There has been huge public interest in a modern revival of the Supra legend - and this concept points to a sports car deserving of the famous name," he said.

"Revealing a racing concept ahead of a production model highlights that motorsport is Toyota's proving ground of choice for high-performance vehicles.

"The GR Supra Racing Concept makes it clear Toyota is developing the Supra to be a true driver's car."
