The Toyota GR Corolla (Japanese: トヨタ・GRカローラ, Hepburn: Toyota Jīāru Karōra) is a compact car manufactured by Japanese marque Toyota since 2022 with assistance from the company's Gazoo Racing (GR) division. It is a hot hatch variant of the E210 series Corolla.

The GR Corolla was introduced on March 31, 2022. The GR Corolla is built mainly for the North American market as Europe received the GR Yaris (which is not sold in Canada and the United States). Both vehicles are assembled at the "GR Factory" inside the Motomachi plant, a production line dedicated to GR-branded vehicles. Aside from North America, the GR Corolla is also sold in Japan, Thailand (limited to nine units),^[2] Malaysia,^[3] Australia, New Zealand, Philippines, Brazil, South Africa, and Indonesia.^[4]

Overview

In 2020, Toyota unveiled the GR Yaris, a hatchback developed by the company's Gazoo Racing (GR) division for its World Rally Championship (WRC) team.^[5] It is not sold in the United States and Canada because the regular Yaris, upon which it is nominally based, isn't sold in those markets due to lack of demand.

The decision led to years of speculation that Toyota would eventually bring a hot hatch to the United States and Canada. The introduction of the vehicle was delayed by a year, because Akio Toyoda, then CEO of Toyota, also a racing driver, was not satisfied with the tuning of a prototype, and asked the GR team to make changes.^[6] Development of the vehicle was led by chief engineer Naoyuki Sakamoto.^[7]

On March 31, 2022, the GR Corolla was introduced, which while based on the larger E210 series Corolla compact hatchback, includes several features originally developed for the GR Yaris. The vehicle is powered by the 1.6-liter G16E-GTS turbocharged straight-three engine that powers the GR Yaris. The version of the engine found in the GR Yaris makes up to 200 kW (268 hp; 272 PS), but the version for the GR Corolla generates 221–224 kW (296–300 hp; 300–304 PS) and 370–400 lb⋅ft (502–542 N⋅m) of torque. Among other strategies to achieve this increased power output, the GR Corolla has three tailpipes for reduced backpressure.^[8][9] A six-speed manual transmission is standard in the GR Corolla.^[10]

The GR Corolla also uses the GR-Four all-wheel drive system first developed for the GR Yaris. The standard setting is a 60:40 front to rear torque distribution, but it can go as rear-wheel biased as 30:70.^[8]

The vehicle is equipped with Toyota Safety Sense 3.0 suite of advanced driver-assistance systems and Toyota's updated audio multimedia system that debuted on the XK70 series Tundra.^[8]

The GR Corolla is produced alongside the GR Yaris at the "GR Factory" inside Toyota's Motomachi plant. Unlike most automobile plants, the "GR Factory" does not use a conveyor belt assembly line. Instead, vehicles are built at stations with more manual assembly processes. The "GR Factory" employs experienced technicians recruited from throughout the company.^[11]

Special editions

Circuit Edition

The Circuit Edition is a special edition of the GR Corolla which offers performance upgrades such as Torsen limited-slip differentials for the front and rear axles (optional for the Core trim level). It also offers a forged carbon fiber roof, hood bulge with functional vents, matte-black rear spoiler, and other upgrades.^[12]

Morizo Edition

The Morizo Edition (stylized "MORIZO") is a limited-production "track-ready" variant of the GR Corolla with reduced weight, increased performance figures, and enhanced handling, which is both available in Japan and North America. The curb weight was reduced by approximately 45 kg (100 lb) from the Circuit Edition model to 1,445 kg (3,186 lb) by removing the rear seats, adding forged carbon fiber roof (also available on the Circuit Edition), removing the speakers and window regulators from the rear doors, and removing the rear wiper blade and motor. The engine torque output was increased by 30 N⋅m (22 lb⋅ft) to 400 N⋅m (295 lb⋅ft), while the horsepower figure remain unchanged. To improve handling, the suspension was re-tuned with monotube shock absorbers, 10 mm (0.4 in) wider tires on lighter rims were used, and body rigidity was increased with 349 additional spot welds, over an additional 6 m (19.7 ft) of structural adhesive, and body reinforcement braces. Engineers adjusted the transmission gear ratios, differential gear ratio and engine tuning to support sustained acceleration at peak torque on the Morizo Edition.^[13][14][15]

The special edition was named after "Morizo", the pseudonym used by Akio Toyoda when participating in races.
