A vehicle in perfect balance2/5/2024 ![]() Increasing strength in some areas but actually decreasing it in others to strike the right balance, the body engineers adopted high tensile sheet steel widely throughout the bodyshell to combine light weight with efficient impact absorption and optimum torsional stiffness.ĩ80 MPa high tensile steel has been adopted for areas such as the roof side rails, front header and centre pillar reinforcement, and 1,500 MPa grade hot-pressed steel used for the roof centre reinforcement. Ultimately, this policy lead to a reduction in the usage of common parts in the GT86 to just 9%.Įstablishing the correct body rigidity is also a delicate balance between performance and weight gain. For instance, the common fuel tank used initially was replaced with a model-specific design which has a particularly unusual shape in order to fit the space available. It was decided that the key to minimising weight was to maximise the use of specialised, exclusive parts, through a 'Common Parts Reduction Campaign'. Only a genuinely lightweight machine offers the intimacy and involvement of a car that can be driven as if it were an extension of the driver's body.Ī car with a 2.0 litre engine of this class is normally about 1,300 kg, but Toyota was determined to make the GT86 weigh around 1,200 kg, guaranteeing an excellent power-to-weight ratio. Making it lightweight was synonymous with honmono kan making it authentic. Weight saving was fundamental to the development of the GT86. Osaka's approach was to alternate testing between the track itself and the surrounding country roads, thus realising both the durability necessary for endurance racing and the handling to full engage drivers during everyday use. The Nurburgring played a particularly important role in helping chief test driver Akihiro Osaka and his team test and tweak the vehicle. The GT86's unique powertrain format combines with the world's most compact four-seat sports car design, light weight, low inertia and a low centre of gravity for the best possible power-to-weight ratio.įine-tuning of the GT86's suspension, brakes and steering has maximised the benefits of its minimal mass, supercar-rivalling lack of inertia and ultra-low centre of gravity, allowing drivers to fully exploit the purity of the new Toyota sports car's outstandingly nimble handling, dynamic agility and cornering poise.
