Toyota Gazoo Racing (TGR) has announced that the GR Yaris will soon be offered with a new “Aero Performance Package”, set to arrive at Toyota dealerships in Japan from 1 October 2025. The package, which has been developed with direct input from motorsport, brings a suite of aero upgrades aimed at enhancing cooling, stability, and balance at high speeds.
The GR Yaris has always had its DNA rooted in rallying, and this package takes that link a step further. Engineers fine-tuned the components through extensive testing in the Super Taikyu Series and Japanese Rally Championship, with feedback from professional drivers shaping the final setup. Available exclusively on the RZ “High Performance” and RC trims, the package combines six carefully designed parts to push the car’s aerodynamics and handling even further.
Among the highlights is a ducted aluminium bonnet, modelled after the carbon-fibre version fitted to the GRMN Yaris. Developed and tested in rally competition, it improves cooling by drawing hot air out of the engine bay. To keep the car planted at speed, a new front lip spoiler has been added to cut front lift and sharpen overall balance — a component included after race driver feedback suggested the aero setup needed an extra layer of stability.
Fender ducts channel trapped air from the front wheel arches, improving steering feel under heavy braking and enhancing stability when turning in. Underneath, a redesigned fuel tank cover smooths airflow across the floorpan, taking inspiration from the flat-bottomed design of the Super Taikyu race car’s safety tank.
At the rear, the upgrades get even more serious. A large adjustable wing increases downforce and helps keep the car steady under hard braking, reducing the “snaking” effect at high speeds. Drivers can alter its angle depending on whether they’re pushing hard on track or cruising on the road. The rear bumper has also been reworked with integrated ducts to reduce drag and eliminate the parachute effect, a solution born out of real racing conditions where bumpers were being ripped off under extreme aerodynamic loads.
Altogether, the Aero Performance Package transforms the GR Yaris into a sharper, more track-focused machine while retaining the usability that makes it so popular among enthusiasts. It’s a clear example of motorsport lessons being fed directly back into road cars — and one that should make the already ferocious GR Yaris even more exciting to drive.
