A car like the GR Corolla needs to back up its aggressive styling with equally aggressive performance chops. Luckily, Toyota is offering a very compelling spec sheet with this new hot hatch, headlined by an angry little engine.
At 1.6 liters with a single-scroll turbocharger and a grand total of three cylinders, the GR Corolla’s powerplant looks and sounds like the mechanical equivalent of a little dog with a Napolean complex. Luckily, the Shih Tzu also knows jiu-jitsu.
In Core and Circuit trims, the 1.6-liter turbo-three powertrain makes an even 300 horsepower and 273 pound-feet of torque. In the Morizo trim, that torque figure gets a healthy bump up to 295 lb-ft. A six-speed manual is the only available gearbox, and all-wheel drive (AWD) comes standard on every GR Corolla.
The manual transmission is equipped with rev-matching technology, making downshifts accurate and easy, and although the clutch travel is long, the bite point is easily identified. A mechanical handbrake sits between the front seats, making automotive hooliganism easy, too.
The GR Corolla Core model operates with open differentials at the front and rear, but both the Circuit and Morizo trim levels swap in front and rear limited-slip differentials. Toyota has also fitted the AWD system with three settings: “front,” which splits power so 60% goes to the front axel and 40% goes to the rear, “track,” which keeps a 50:50 balance, and “rear,” which directs 70% of the engine’s output to—you guessed it—the rear axle.
Be warned: despite the GR Corolla’s spec sheet, it doesn’t fully reveal itself as a performance car until the tachometer rises past 3,500 RPM. In fact, below that threshold, it feels surprisingly like a regular Corolla.
Take it over 3,500 RPM, though, and we’re telling a completely different story. 60 miles per hour arrives in roughly 5 seconds (4.9 for the Morizo trim level). The top speed measures 142.9 mph, which seems ludicrous in a car this size.
Better, while the engine is easy to focus on, it’s the GR Corolla’s rigidity and transmission gearing that make it a special performer.
Yes, the GR Corolla is fast, but it screams with the Morizo treatment. The closer gear ratios in the Morizo trim mean it’s pushing the rev-limiter sooner and faster when all other elements are equal. While testing the GR Corolla on a track, we’d approach some corners in the Core and Circuit trim comfortably at the top of third gear. But when we tackled those same lines in the GR Corolla Morizo trim, we found ourselves shifting to fourth well before the brake point.
Once we hit the corner and the laws of physics started making themselves known, the Morizo’s better tires (Michelin Pilot Sport Cup 2 vs Michelin Pilot Sport 4) and stiffer underpinnings also made themselves known.
The GR Corolla’s short, 103.9-inch wheelbase wants to rotate, and when equipped with the Pilot Sport 4 tires, the Core and Circuit trims feel a bit more playful in spirited driving.
There’s also very little flex in the GR Corolla’s chassis, especially in the Morizo trim, which benefits from significantly more structural adhesives, plus a rear-seat delete and two braces spanning the rear of the cabin. The added rigidity is noticeable.
Yet, considering how rigid the GR Corolla feels on a race track, the suspension proved relatively compliant when driving around the beaten-up ring road circling said race track. We’re not sure the Morizo would be ideal, what with its stiffer architecture and missing rear seat, but the Core and Circuit trims could be daily drivers.
