TOKYO: Toyota Gazoo Racing (TGR) will launch the GR Yaris "Aero performance package", on the RZ "High performance" and RC trim levels, in Japan on Oct 1, 2025.
TGR said the GR Yaris "Aero performance package" incorporates insights gained from motorsports, and was developed together with professional drivers.
The "Aero performance package" maximises aerodynamic performance enhancement through the combined installation of six items.
Ducted aluminum hood
During high-speed driving, a ducted aluminum hood, which shares the shape of the carbon-fiber hood used on the GRMN Yaris and which was developed by entering a car installed with it in the Japanese Rally Championship, improves cooling by discharging engine compartment heat.
To achieve the high level of aerodynamic balance learned by competing in the Super Taikyu Series, a front lip spoiler suppresses the generation of front lift to enhance front ground contact and aerodynamic balance, improving the vehicle's overall lift balance.
Initially, five items, excluding the front lip spoiler, were considered for the "Aero performance package".
But, based on feedback from professional race driver Oshima, a higher level of balance was sought, ultimately resulting in the addition of this front lip spoiler.
Fender ducts
Fender ducts release rearward air that accumulates in the front wheelhouses, improving the steering feel during nose dives and handling stability when entering corners.
A fuel tank undercover, drawing inspiration from the flat shape of the bottom of the safety fuel tank of a car entered in the Super Taikyu Series, optimises the airflow under the vehicle body and improves aerodynamic performance.
A large variable rear wing contributes to handling stability at high speeds and suppresses snake-like movement during braking.
Because it is adjustable, its angle can be changed depending on the driving situation at hand, such as on a circuit, for enjoyable driving.
Rear bumper ducts suppress the rear bumper's parachute effect and decrease the drag coefficient.
Spawning from the case of a rear bumper being detached due to aerodynamic loads while competing in the Super Taikyu Series, in which cars are subjected to severe conditions, the ducts were developed to cope with the uniquely harsh environments of motorsports.
