Aerodynamic and lightweight body design, producing power-to-weight ratio of 5kg per bhp The new GR Yaris is a pure performance car, born from Toyota's title-winning experience in the World Rally Championship (WRC). Forged from success in the heat of competition, it brings motorsport technology and design directly to the world of the road car, true to Toyota Gazoo Racing's ethos of making ever-better cars that are intrinsically rewarding and fun to drive. Positioned at the top of the all-new Yaris range, the GR Yaris is a unique model that benefits from the design and engineering skills of Toyota Gazoo Racing and Tommi Mäkinen Racing, Toyota's partner in the WRC. As well as serving as the official homologation model for development of the next Yaris WRC car, it also has all the attributes required for owners looking to compete successfully in local rally competitions. Presenting the GR Yaris at the 2020 Tokyo Auto Salon, Gazoo Racing President Shigeki Tomoyama said: "One of Toyota Gazoo Racing's commitments is to use motorsport to refine its knowhow and its personnel, with the aim of launching world-class production sports cars.
While the new GR Supra is a sports car developed through track racing, the GR Yaris has been devised through our participation in rallies – something that many of our fans have been waiting for." Every aspect of the car has a performance focus: an all-new platform and engine, new suspension, lightweight construction, aerodynamic styling and a new GR-Four permanent all-wheel drive system. The new GR Yaris is Toyota's first genuine all-wheel drive sports car and its first homologation model for World Rally Championship competition since the end of production of the Celica GT-Four in 1999. As a homologation model, the GR Yaris will support the development of a new competition car for the Toyota Gazoo Racing World Rally Team's WRC campaign. The WRC-skilled team of designers and engineers at Tommi Mäkinen Racing focused on perfecting the aerodynamics, weight distribution and light weight of the new car – the three qualities essential to achieving the best performance and drivability. A lower roofline improved the car's ability to cut through the air, while positioning the new 1.6 turbo engine further back towards the centre of the car and locating the battery in the boot helped produce a better chassis balance for improved handling, stability and responsiveness.
To help meet its performance goals for the GR Yaris, Toyota has established a new production facility at its Motomachi factory, with a line dedicated to manufacturing GR sports cars. In addition, the GR also comes with three driving modes; Normal, Sport and Track with the middle setting resulting in up to 70% of the amount twist going to the rear wheels only, while other changes include a double wishbone rear suspension, revised MacPherson struts at the front and upgraded brakes utilising a red painted, grooved four-piston caliper setup at the front and two at the rear with the respective discs measuring 356 mm and 297 mm. From the options list, buyers can opt for the so-called Circuit Pack developed at Gazoo Racing's Motomachi Plant that adds two Torsen limited slip differentials on the front and rear axles, performance tuned suspension and forged alloys wrapped in Michelin Pilot Sport 4 S rubber. While no details of the GR's interior specifications were revealed, what has been announced are the performance figures and outputs of the all-new 1.6-litre turbocharged three-cylinder engine claimed to the lightest of its kind in the world. Toyota unveils world's most powerful three-cylinder hot hatch: epic 192kW output for all-wheel-drive GR Yaris. Although price is yet to be announced, Toyota has laid bare all the facts and figures behind its first in-house all-wheel-drive performance car in 20 years. An epic output of 192kW is believed to make the Toyota GR Yaris the most powerful three-cylinder in the world. Because the three-door Toyota GR Yaris weighs less than 1300kg – 1280kg without the driver – the car has a better power-to-weight ratio than the Volkswagen Golf GTI and Golf R, Hyundai i30N, Renault Megane RS, and the Subaru WRX and WRX STI. Toyota designed and developed the GR Yaris to form the basis of its next World Rally Championship program, but hopes it will become popular among circuit racers and weekend track day warriors.
