A three-cylinder block is an unusual basis for a racing engine. Yet Toyota went there, out of manufacturing efficiency and for the technical achievement of creating one of the most power-dense engines on earth. The 1.6-litre turbocharged unit makes 300 horsepower and 295 pound-feet of torque with smooth and linear delivery, a sonorous intake, and baritone exhaust notes.
Paired with a six-speed manual transmission with tall lower gears, the GR Corolla takes off like it's been rear-ended and does not run out of steam. It's a forceful and steady build of speed, and like the Volkswagen Golf R, the GR Corolla accelerates with a calmness that belies its tuner car appearance. The heavy clutch spring requires a lot of throttle modulation at low speeds and there's drivetrain rattle, but the engagement point is easy to place and the shifter's short throws are satisfying.
Honda's laser-precise manual is still the best, but the GR Corolla's wow factor is the GR-Four AWD system that outpaces VW and Subaru in its uncanny ability to route torque everywhere. Two limited-slip differentials and a multi-plate clutch pack ensure no wheel is spinning under hard acceleration or cornering. In normal mode, the GR-Four system sends 60% of torque to the front wheels. Gravel locks the split to 50-50, and Track mode is the most variable as it can switch from a 60/40 split to a 30/70 split and anywhere in between. This is the type of robust AWD that used to be available on rally-inspired performance cars such as the Mitsubishi Lancer Evo and the Subaru WRX STI.
The GR Corolla is fun and controllable in any weather. The steering is perfectly weighted and quick without being twitchy — a hard feat on a short-wheelbase chassis, which inherently amplifies small movements.
The suspension, however, is rock hard all the time. During a daily commute, the GR Corolla is uncomfortable and plagued with road noise. Insulation and adaptive dampers are not on the order sheet, but riding like a stone also translates to feeling rock solid at higher speeds. A MacPherson strut front and double wishbone rear, along with thick stabilizer bars and high spring rates, keep the car settled without it scampering over dips and bumps. Those inside will bounce around, but the car won't.
For 2026, Toyota added exactly 13.9 metres of structural adhesive to further stiffen the Corolla's body. Combined with that stiff suspension, the forged carbon roof, an optional rear chassis brace, and sticky Michelin Pilot Sport 5 tires, the GR Corolla can outpace cars with double the power on a tight back road. This little car makes it look easy.
Braking is exemplary thanks to 14-inch front rotors and a relatively light curb weight that tops out at 1,515 kilograms (3,341 pounds) on the Premium with the eight-speed automatic transmission. The latter adds more weight and a launch control function, but unlike the dual-clutch automatic in the Hyundai Elantra N, it's not worth the extra cost and detracts from the car's sprightliness. Also worth a cursory mention is Active Sound Control, a new feature that ratchets up the already loud engine in the cabin with a choice of three volume levels. We left it off.
Fuel economy is rated by Natural Resources Canada at 11.1 litres per 100 kilometres in the city, 8.3 on the highway, and 9.8 combined with the manual transmission and 12.1 L/100 km city, 8.6 highway, and 10.5 combined with the automatic. A tiny 50-litre fuel tank, combined with the driver's eagerness, equals mediocre real-world range.
