      This week, Toyota introduced the 2026 GR Corolla for the North American market, just a week after its Japanese counterpart was launched. As expected, many of the updates and enhancements are consistent across both regions; the new GR Corolla now incorporates about 15 additional yards of structural adhesive, improved cooling, and a new premium sound system featuring a subwoofer. However, one announcement from Toyota for existing GR Corolla owners in Japan caught our eye: an optional “software-inclusive upgrade program” that would provide earlier models with the same 22 lb-ft torque increase offered in the 2025 and later versions. Naturally, we hoped that Toyota would extend this option to other markets, but we regret to inform you that's not going to happen.

      A spokesperson from Toyota North America stated to The Drive that “unfortunately, there won’t be a software upgrade for the U.S. GR Corollas,” which is disappointing. Not only does this update unlock additional torque, aligning it with the 295 lb-ft of the new models, but it also modifies the torque-splitting system of the hot hatch.

      To explain, the 2023 and '24 GR Corollas offered three options for power distribution: a standard 60/40 mode (with 60% to the front axle and 40% to the rear), a 30/70 option, and a “Track” mode that was fixed at 50/50. However, starting with the last model year, Toyota made adjustments. There remains a 60/40 “Normal” mode, but the “Track” mode has been updated to dynamically shift from 60/40 to 30/70 to optimize grip (and presumably keep the rear clutch pack cool). Additionally, a 50/50 mode still exists but is now labeled “Gravel.”

      Still confused? Yes, despite Toyota's efforts to clarify the torque distribution options for drivers, the subtleties of their functions remain somewhat unclear. That said, it appears that Toyota North America will not provide owners here the chance to discover this for themselves. In Japan, the automaker indicates that the program's availability is expected to commence in the spring of next year, with pricing yet to be revealed.

      This is indeed disappointing. Look—when it comes to technology, I’m generally optimistic. I believe it can enhance our vehicles, even if it sometimes feels otherwise. Many automakers tout that one of the major advantages of this new software-defined automotive era is the potential for formerly static products to evolve and improve without the need for new components or hardware. Although the GR Corolla may be traditional in the sense of being gas-powered and equipped with a six-speed transmission, it is still reliant on software. Japanese customers will have the opportunity to benefit from this and enhance their cars. Fantastic.

      The issue often lies in experiencing the downsides of technology—consider unwanted subscription services that continually charge for features that previously were either included or absent, or automakers releasing glitchy and unfinished infotainment systems with the mindset that they can always be finalized later—while missing out on the benefits. And this would indeed be a benefit! While I understand that skeptics may doubt any company offering performance enhancements through software updates, the reality is that the GR Corolla and Yaris demand a great deal from their spirited little turbo three-cylinders. If Toyota initially chose to be cautious and limit torque, but now believes it's unnecessary, that's perfectly acceptable to me.

      Ultimately, just provide consumers with the option. This is a low-volume car, and owners are aware that this update exists somewhere—they're just being denied access. Given how the GR Corolla has seen improvements each year, this update could significantly alleviate their feelings of missing out.
