Toyota GR Yaris Upgrade 2025: Toyota continues to show its commitment to passionate drivers by offering an exciting software upgrade for the pre-facelift GR Yaris. For just £995, owners of the original version of this rally-bred hot hatch can now access a boost in torque and several new dynamic driving settings. This is not just a routine update—it’s an enhancement that transforms the already potent GR Yaris into an even sharper performance machine. Installed by Toyota technicians as a “while-you-wait” upgrade at local dealerships across the UK, this new offering highlights Toyota’s dedication to continuous improvement and customer satisfaction.
The update, which Toyota itself describes as “a software update not to be ignored,” brings substantial benefits without compromising the warranty or emissions compliance. The most notable change is a torque increase from 266 lb-ft to 280 lb-ft, achieved through an ECU remap. This allows drivers to experience improved mid-range pull and quicker acceleration, especially useful on twisty roads and track days. Alongside this, Toyota has added advanced customization options, giving drivers even more control over how their car behaves in various conditions.
In a world where most updates are cosmetic or infotainment-related, Toyota’s focus on mechanical and performance tweaks through software is refreshing. The GR Yaris already enjoys a cult-like status thanks to its rally roots, turbocharged engine, and GR-Four all-wheel-drive system. Now, with added torque and bespoke drive mode settings—including adjustable power distribution ratios (55:45, 50:50, or 45:55)—the hot hatch gets closer to full race-bred flexibility. Even features like power steering weight and throttle responsiveness can be tuned by the driver, adding a layer of personalization that is often reserved for far more expensive performance cars.

Performance Upgrades You Can Feel
While the horsepower remains unchanged at 257 bhp, the increase in torque dramatically changes the car’s in-gear acceleration and low-end responsiveness. The GR Yaris, already known for its ferocious performance and tight handling, now becomes even more dynamic. Drivers will especially notice the changes in corner exits and overtaking scenarios, where extra torque makes a tangible difference.
What truly elevates the update is the added control over vehicle dynamics. The ability to shift power balance between the front and rear axles on the fly gives the GR Yaris a level of agility and adjustability that’s usually found in high-end performance cars. Combine that with the new throttle and steering settings, and you essentially have a car that adapts to your driving style with the push of a button.
Exterior and Interior Design
The design of the GR Yaris remains unchanged with the software update, retaining its wide stance, aggressive front fascia, flared wheel arches, and rally-inspired aerodynamic design. However, the updated driving modes make the car feel more performance-oriented even though its looks are already razor sharp.
Inside, the cabin continues to reflect its motorsport DNA with bolstered sport seats, a focused cockpit layout, and high-grip materials. With the added steering and throttle responsiveness modes, the driver experience becomes even more immersive and tailored—especially for those who live for precision driving.
Price and Availability
The upgrade is priced at £995 and is now available across Toyota UK dealerships. It’s a one-time install that can be completed during a regular service appointment, making it convenient for owners to upgrade without leaving the car overnight.
