The Toyota Corolla Hatchback XII (E210) GR 1.6, produced from March 2022 to August 2024, represents a significant departure for the Corolla nameplate, transforming it from a traditionally economical compact car into a high-performance hatchback. This variant, designated GR-FOUR iMT, is a limited-production model designed to compete with other hot hatches like the Volkswagen Golf GTI and Honda Civic Type R. It’s built on the E210 Corolla Hatchback platform (also known as the Auris in some markets) and represents Toyota’s commitment to injecting excitement into its lineup through the GR (Gazoo Racing) sub-brand. The GR 1.6 iMT sits at the very top of the E210 Corolla Hatchback range, offering a substantial performance upgrade over the standard gasoline and hybrid models.
GR-FOUR iMT: Positioning and Overview
The GR 1.6 GR-FOUR iMT is the performance flagship of the E210 Corolla Hatchback series. Unlike the standard Corolla Hatchback, which focuses on fuel efficiency and practicality, the GR model prioritizes driving dynamics and outright speed. It’s positioned as a direct competitor to established hot hatches, offering a unique combination of all-wheel drive, a turbocharged three-cylinder engine, and a driver-focused manual transmission. The “iMT” designation stands for Intelligent Manual Transmission, a system designed to enhance the driving experience without fully automating gear changes. This model was not intended for high-volume sales; instead, it was created to showcase Toyota’s engineering capabilities and rally-inspired performance heritage.
Powertrain & Engine Architecture
The heart of the GR 1.6 is the G16E-GTS engine, a 1.6-liter, inline-three cylinder gasoline engine. This isn’t a simple modification of a standard Corolla engine; it’s a completely new design developed specifically for the GR models. It boasts a relatively high compression ratio of 10.5:1 and utilizes a single-scroll turbocharger with an intercooler to produce 304 horsepower at 6500 rpm and 370 Nm (272.9 lb-ft) of torque between 3000-5550 rpm. The engine features multi-port fuel injection and a DOHC (Dual Overhead Camshaft) valvetrain. The engine’s compact size and lightweight construction contribute to the car’s balanced handling. The engine oil capacity is 4.3 liters (4.54 US quarts / 3.78 UK quarts), and requires a specific oil specification (details available through Toyota service documentation).
The “iMT” transmission is a six-speed manual gearbox with an electronically controlled clutch. While it requires the driver to operate the gear lever, the system automatically matches engine speed during downshifts, providing smoother transitions and reducing the risk of stalling. This system doesn’t fully automate the clutch, maintaining driver engagement while simplifying the driving experience. The GR-FOUR all-wheel-drive system is a key component of the car’s performance. It utilizes a multi-plate clutch to distribute torque between the front and rear axles, with the ability to vary the split from 60:40 to 30:70 depending on driving conditions. This allows for both confident traction and a playful, rear-biased handling characteristic.
Driving Characteristics
The GR 1.6 GR-FOUR iMT delivers a distinctly sporty driving experience. The turbocharged three-cylinder engine provides strong acceleration, with peak torque available over a broad rev range. The iMT transmission, while not a traditional manual, offers a satisfying level of driver involvement. The GR-FOUR all-wheel-drive system provides exceptional grip, allowing the car to corner with confidence and maintain stability in various weather conditions. The car’s relatively lightweight construction (1475 kg / 3251.82 lbs) contributes to its agile handling. Compared to the standard Corolla Hatchback, the GR model offers significantly improved acceleration, braking, and cornering performance. The gear ratios are tuned for performance, prioritizing acceleration over fuel economy. The power delivery is linear and predictable, making the car accessible to drivers of varying skill levels.
Equipment & Trim Levels
The GR 1.6 GR-FOUR iMT came with a comprehensive list of standard equipment, reflecting its performance-oriented nature. Interior features typically included sport seats with enhanced bolstering, a leather-wrapped steering wheel, and aluminum pedals. The dashboard configuration featured unique GR-branded instrumentation and a prominent infotainment screen. Standard safety features included ABS (Anti-lock Braking System), stability control, and a suite of driver-assistance systems. Optional extras were limited, as the GR model was already well-equipped. Available options often included premium paint colors and upgraded audio systems. The interior upholstery was typically a combination of fabric and synthetic leather, with a focus on providing support and comfort during spirited driving.
Chassis & Braking
The GR 1.6 GR-FOUR iMT features a reinforced chassis compared to the standard Corolla Hatchback, enhancing rigidity and improving handling. The front suspension utilizes an independent McPherson strut setup with coil springs and an anti-roll bar, while the rear suspension employs a double wishbone configuration with a transverse stabilizer. This suspension setup is tuned for performance, providing a firm but controlled ride. The braking system consists of ventilated discs on all four wheels, with front discs measuring 457.2 mm and rear discs measuring 406.4 mm. The brakes provide strong stopping power and resist fade during repeated use. The steering system is a rack and pinion setup with electric power steering, offering precise and responsive control.
Market Reception & Comparison
The Toyota Corolla GR 1.6 GR-FOUR iMT received overwhelmingly positive reviews from automotive critics. It was praised for its engaging driving dynamics, powerful engine, and effective all-wheel-drive system. Critics noted that it offered a compelling alternative to established hot hatches, providing a unique blend of performance and practicality. Compared to other trims in the Corolla Hatchback lineup, the GR model represents a significant step up in terms of performance and handling. While the standard Corolla models prioritize fuel efficiency and affordability, the GR model focuses on delivering a thrilling driving experience. Fuel economy is understandably lower on the GR model due to its higher output engine. Reliability is expected to be strong, consistent with Toyota’s reputation, although the long-term durability of the turbocharged engine and all-wheel-drive system remains to be fully assessed.
