The Toyota Mark II GX90 2.5 i 24V, produced between 1992 and 1996, represents a significant iteration of Toyota’s long-running Mark II lineage. This model, falling within the eighth generation (GX90 chassis), was positioned as a mid-to-upper range offering, bridging the gap between the more basic models and the higher-performance variants like the turbocharged models. The GX90 Mark II aimed to provide a blend of comfort, refinement, and respectable performance for the Japanese domestic market, and increasingly, for export markets as well. It was built on the JZX90/GX90 platform, known for its robust rear-wheel-drive configuration and relatively sophisticated suspension design for its time.
Powertrain & Engine Architecture
The heart of the Mark II 2.5 i 24V is the 1JZ-GE engine, a 2.5-liter (2491 cc) inline-six cylinder naturally aspirated gasoline engine. This engine is a key component of the GX90’s appeal, offering a smooth and relatively powerful driving experience. The 1JZ-GE features a double overhead camshaft (DOHC) valvetrain operating four valves per cylinder, contributing to its strong breathing and power output. Fuel delivery is managed by a multi-port fuel injection system, ensuring precise fuel metering for optimal combustion. The engine’s bore and stroke measure 86 mm x 71.5 mm, respectively, resulting in a compression ratio of 10:1. The engine oil capacity is 5.4 liters (5.71 US quarts or 4.75 UK quarts), and the recommended oil specification should be consulted in the vehicle’s owner’s manual.
Paired with the 1JZ-GE is a four-speed automatic transmission. This transmission was chosen to provide ease of use and a comfortable driving experience, aligning with the Mark II’s positioning as a more luxurious and accessible vehicle. While not offering the driver engagement of a manual transmission, the automatic provided smooth shifts and contributed to the car’s overall refinement. The transmission is electronically controlled, optimizing shift points based on throttle position and vehicle speed.
Engine Code Specifics
The 1JZ-GE engine code designates a naturally aspirated version of the 1JZ family. Unlike its turbocharged siblings (1JZ-GTE), the 1JZ-GE prioritizes reliability and smooth power delivery over outright peak horsepower. This makes it a more suitable choice for drivers seeking a comfortable and dependable vehicle for daily use. The engine is known for its durability and relatively straightforward maintenance requirements, although regular servicing is crucial for long-term reliability.
Driving Characteristics
The Mark II 2.5 i 24V with the automatic transmission delivers a comfortable and composed driving experience. The 180 horsepower at 6000 rpm and 235 Nm (173.33 lb-ft) of torque at 4800 rpm provide adequate acceleration for most driving situations. While not a sports car, the GX90 offers a respectable level of performance, particularly when considering its weight of approximately 1370 kg (3020.33 lbs). The automatic transmission’s gear ratios are tuned for smooth cruising and reasonable acceleration, but it doesn’t offer the responsiveness of a manual gearbox. Compared to the turbocharged variants, the 2.5 i 24V feels less urgent in its acceleration, but it provides a more linear and predictable power delivery. The rear-wheel-drive configuration contributes to balanced handling, although it requires careful throttle control in slippery conditions.
Equipment & Trim Levels
The GX90 2.5 i 24V typically came equipped with a range of features designed to enhance comfort and convenience. Standard equipment generally included power windows, power locks, air conditioning, and a basic audio system. Interior upholstery was typically cloth, although leather options were available as upgrades. The dashboard layout was functional and well-designed, with clear instrumentation and easy-to-use controls. Optional extras could include a sunroof, upgraded audio systems, and alloy wheels. The trim level often dictated the availability of these features, with higher trims offering more luxurious appointments.
Chassis & Braking
The Mark II GX90 features a robust chassis with a multi-link suspension system at both the front and rear. This suspension design provides a comfortable ride while maintaining good handling characteristics. The front suspension utilizes several levers and rods to control wheel movement, while the rear suspension is similarly sophisticated. Braking duties are handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) was typically included as standard equipment, enhancing safety by preventing wheel lockup during hard braking. The steering system is a rack and pinion setup with hydraulic power assistance, providing precise and responsive steering feel. The vehicle rides on 195/65 R15 H tires.
Market Reception & Comparison
The Toyota Mark II GX90 2.5 i 24V was generally well-received by critics and consumers alike. It was praised for its comfortable ride, refined interior, and reliable powertrain. Compared to other trims in the Mark II lineup, the 2.5 i 24V offered a good balance of performance and fuel economy. While the turbocharged models provided more exhilarating performance, they also came with higher running costs and potentially lower reliability. The 2.5 i 24V’s fuel consumption of 8.4 l/100 km (28 US mpg / 33.6 UK mpg / 11.9 km/l) was considered reasonable for a vehicle of its size and class. Compared to competitors like the Nissan Laurel and the Mazda Sentia, the Mark II offered a compelling package of features, performance, and reliability.
