The Latest Developments in Automotive Technology
Unveiling significant developments in the automotive industry, Toyota has introduced the 2026 GR Corolla for the North American market, closely following the model’s debut in Japan. Noteworthy updates include an increase of approximately 15 yards in structural adhesive, enhanced cooling mechanisms, and a premium sound system featuring a subwoofer.
However, a particularly intriguing announcement for existing GR Corolla owners in Japan involves a “software-inclusive upgrade program,” which offers a torque enhancement of 22 lb-ft, aligning older models with the specifications of 2025 and subsequent vehicles. Regrettably, this upgrade will not be available to customers in North America.
According to a representative from Toyota North America, there will be no software upgrade for U.S. GR Corollas. This decision is disappointing, as the update not only facilitates a torque increase, raising the total to 295 lb-ft for newer models, but it also modifies the hot hatch’s torque-splitting system.
The 2023 and 2024 GR Corollas offered three torque distribution options: a default setting of 60/40 (60% to the front axle, 40% to the rear), a 30/70 setting, and a “Track” mode that provided equal power distribution.
However, Toyota has refined these settings for the latest models. The current configuration retains the 60/40 “Normal” mode, while “Track” mode now accommodates a dynamic torque distribution ranging from 60/40 to 30/70, presumably to optimize grip and maintain rear clutch pack temperature.
Additionally, a 50/50 mode has been rebranded as “Gravel.” At left, the GR-Four dial in a 2023 GR Corolla. At right, the same dial in a 2025 model. Notice the difference in the labeling.
Despite Toyota’s attempts to elucidate these torque distribution options, the intricate nature of their operation remains somewhat perplexing. Unfortunately, it appears that North American owners will miss out on the opportunity to explore these enhancements for themselves.
In contrast, Japanese consumers should expect the availability of the upgrade program beginning in the spring of the coming year, though specific pricing details have yet to be disclosed.
This situation is undeniably disappointing. As a staunch advocate for technological advancement within the automotive realm, it’s disheartening to witness missed opportunities for innovation without necessitating physical modifications.
While the GR Corolla may embody traditional engineering with its gasoline reliance and six-speed transmission, it is still heavily governed by software. Japanese customers will gain the ability to enhance their vehicles, a feature that North American enthusiasts will regrettably forfeit.
Often, we are exposed to the drawbacks of rapidly evolving technology—such as subscription services that monetize features previously standard—while failing to enjoy the benefits. This software update represents a distinct advantage.
Although skeptics may question a company’s intent in selling performance upgrades via software, it is important to recognize that the GR Corolla and Yaris demand considerable performance from their compact turbocharged engines.
If Toyota initially opted to limit torque for safety reasons and has since deemed it unnecessary, that shift is entirely reasonable.
Ultimately, it is imperative to provide consumers with a choice. As a low-volume offering, GR Corolla owners are likely aware of the existence of this upgrade, yet they have been unjustly excluded from it.
Given the consistent improvements made to the GR Corolla each year, implementing this update could significantly alleviate owners’ feelings of being left out.
