The fifth generation of Toyota’s legendary Supra sports car and the first global GR model to be produced by Toyota GAZOO Racing, made its world debut at Detroit’s North American International Auto Show show.
The GR sports a classic layout of a front-mounted engine driving the rear wheels and Its 3.0-litre, straight-six engine, that benefits from a twin-scroll turbocharger, produces 250kW and 500Nm of torque.
Toyota says that GAZOO Racing was instrumental in honing the new sports car’s performance, working extensively on the Nürburgring track and surrounding roads in Germany in order to achieve the most agile, stable and rewarding handling. Further testing was also carried out on roads around the world, including in Australia with chief engineer Tetsuya Tada.
The driver’s cockpit combines traditional GT elements with ultra-modern functionality with Toyota saying its design was directly influenced by the layout found in single-seater race cars.
The performance heart of the GR Supra is its 3.0-litre in-line six-cylinder engine. It is fitted with a twin-scroll turbocharger, high-precision direct fuel injection and continuously variable valve control. It is matched to an eight-speed automatic transmission that provides lightning-fast up and downshifts, with short ratios selected for the lower gears. The driver can take control of gear changes using paddle shifts on the steering wheel and can select Normal or Sport driving modes to suit their preference and the conditions.
A Launch Control function enables acceleration from standstill with maximum traction, helping the car move from rest to 100 km/h in a claimed 4.3 seconds.
Engine sound and response, shift pattern, damping, steering and active differential performance are adjusted when the driver selects Sport mode.
The vehicle stability control has a special “track” setting that can be selected, reducing the level of system intervention so the driver has greater control of the vehicle’s dynamic performance.
All versions of the Toyota GR Supra sold in Australia will be fitted with an active differential that operates both when accelerating and decelerating and can seamlessly adjust from zero to full, 100% lock, with instant response.
A dedicated ECU monitors a wide range of inputs, including steering wheel, throttle and brake pedal operation, engine speed and yaw rate, for appropriate triggering of the actuator.
A new suspension design comprises double-joint spring MacPherson struts at the front and a five-link system at the rear. Toyota says the front suspension subframe and control arm mounting points have been made extremely rigid to yield precise cornering characteristics, while the use of aluminium for the control arms and swivel bearings reduces the car’s unsprung weight, giving superior agility.
The new GR Supra also features high-performance wheel hubs with sports-tuned electric power steering.
The rear suspension benefits from a similarly lightweight design for the rigid subframe and the bracing that connects it to the body, helping ensure extremely precise wheel control.
High-performance systems and features include an active differential, adaptive variable suspension, and available 19-inch forged alloy wheels with a high-performance brake package and aa array of advanced safety features.
