Toyota's new GT 86 sports car is making its debut at the Tokyo motor show this week.
The compact 2+2 has been conceived as an entirely driver-focused machine, designed to deliver the core qualities of the classic sports car experience. That means precise, instant response to the smallest throttle and steering inputs and the kind of performance that appeals to those for whom driving is a passion, not a necessity.
 The GT 86 is built on a new platform, with a highly aerodynamic bodyshell stretched tight over the car's mechanical elements. Rather than fitting a heavy, large capacity powertrain, Toyota has opted instead to go back to its sporting roots, installing a compact, front-mounted, free-revving petrol engine that drives the rear wheels.
This four-cylinder "boxer" unit generates 197bhp at 7,000rpm and maximum torque of 205Nm at 6,600rpm, giving the GT 86 brisk, engaging performance.
The powertrain is matched to the world's most compact four-seat design to create a car that benefits from light weight, low inertia and a low centre of gravity to achieve the best possible power-to-weight ratio. For the driver that means lively, accessible performance and dynamic character with minimal intrusion from electronic systems.
Both the powertrain and the driving position have been set as low and as far back as possible to achieve the best balance: the car has a near-perfect 53:47 front-to-rear weight distribution. The flat-four engine format and the driver's hip point – the lowest of any current Toyota production model – together give the GT 86 an ultra-low centre of gravity, at just 460mm.
The GT 86 makes the most of a light kerb weight, making it easy for drivers to exploit its nimble handling and cornering poise. The suspension features MacPherson struts at the front and double wishbones at the rear. The car rides on 17-inch wheels and is fitted with ventilated disc brakes fore and aft.
The GT 86's engine is the result of a joint Toyota and Subaru development programme that brings together their technical know-how and mutual passion for sports cars. Toyota has added its D-4S injection technology to Subaru's new, horizontally opposed, naturally aspirated 1,998cc four-cylinder boxer engine. This system features separate twin injectors for both direct and port injection, and a high 12.5:1 compression ratio, increasing power and torque across a wide range of engine speeds without sacrificing fuel efficiency and environmental performance.
