The “Old” Morizo Edition

If the Circuit Edition isn’t enough, the Toyota GR Corolla Morizo Edition took things even further with weight saving and performance measures. Even though you can’t buy one new anymore, it is still worth talking about.

Like the previous and current Circuit model, the Morizo has a forged carbon-fiber roof, and the package deletes the rear seats, speakers, window regulator, and wiper blade for a total savings of about 100 pounds. The suspension has a stiffer spring rate and is lowered 0.2 inch to bring ground clearance down to just 5.1 inches. With a stiffer suspension, it was important to stiffen the body, even more than the improvements over the standard Corolla Hatchback. The Morizo added a rear-suspension tower brace and a floor brace where the rear seats were mounted. Structural adhesive is more than double what the Core and Circuit added, for nearly 20 feet more material that reinforces the front, rear, and hatch door openings. The Morizo does not share the sport spoiler with the Circuit edition; it keeps the standard lip spoiler, but all GR Corollas share the same 0.35 drag coefficient.

Peak horsepower remains the same, but upping the turbo boost from 25.2 to 26.3 psi narrows the torque band to 3,250–4,600 rpm. Toyota swapped first and third gear in the Morizo’s transmission for a closer-ratio gearset to take advantage of the new torque curve with quicker shifts, which are made even quicker thanks to a short-throw stick. The weight savings, extra boost, and gear changes don’t add up to much on paper, not even one-tenth quicker to 60 mph by Toyota’s estimates, but it should be enough to change the car’s on-track behavior so skilled drivers can take advantage of the differences.

Despite the seemingly bare interior with so much stripped out of it, the Morizo is still a looker inside. It has a red seat belt with red and black trim details, heated semi-bucket seats, and a heated steering wheel wrapped in Ultrasuede with a red stripe. Toyota offered the model in Windchill Pearl and a new-for-2023 matte Smoke Gray.

Unfortunately, if you want a Morizo, you’ll have to find someone willing to part with theirs. Of course, enterprising individuals could rip stuff out of the back themselves and fabricate some extra braces. If the hot hatch community has taught us anything, it’s that we won’t be surprised to see at least one GR Corolla owner out there do so. Sans the DIY approach, the Core, Premium, and Circuit Edition GRs should be enough to keep everyone content.
