To be clear, there is no suggestion that Toyoda lacks mechanical empathy or skills behind the steering wheel. Instead, this was a deliberate test cycle inspired by the development of race and rally cars. “This was a really important process,” says Saito. “It was the key to making it stronger. In motorsport, the vehicle must be driven in the harshest conditions. During the development of GR Yaris, Mr. Toyoda said,” Break, fix, make stronger. ” I was told to repeat. In the future, this development process can be applied to other models, including GR models and other Toyota models. “
Under the guidance of Toyota and the WRC team, the GR Yaris has begun to take shape unlike any other Toyota-produced car. Its personality goes beyond all-wheel drive systems. The platform is a unique fusion of Toyota’s GA-B and GA-C platforms designed for double wishbone rear suspension, with an all-new 258bhp 1.6-liter turbocharger. The engine is intended to enable future second tier WRC2 competition cars.
Next is the lightweight body shell. It uses virtually nothing from the standard Yaris and makes heavy use of aluminum and forged carbon composites. At the request of the rally team, the roofline has been lowered, spoilers have been added to support the homologation of the Rally1 Yaris in 2022, and the GR Yaris has only three doors instead of five.
The design and final engineering may have come from Gazo Racing, but their design features and technology would not have been possible without the help of a wider Toyota company. “The powertrain department really worked on the engine, and materials engineering helped us with a lightweight body,” explains Saito. “Electrical systems and production engineers also provided amazing support.
“We didn’t have much of the technology we needed in-house, so we put a lot of effort into achieving the performance we wanted at an affordable price.”
That “affordable” point is important, and especially given the cost of developing such a single car, it never sells in the amount normally the world’s largest car makers would normally aim for. But in the worst case, only the company accountant may be a little dissatisfied with the results.
