This powerplant, designated with a 2378 cm³ (145.11 cu. in.) displacement, featured a Double Overhead Camshaft (DOHC) valvetrain with four valves per cylinder, a configuration that was becoming standard for modern engines of its era, ensuring optimal airflow and combustion efficiency. Fuel delivery was managed by a multi-port manifold injection system, contributing to precise fuel metering and consistent performance across the RPM range. As a naturally aspirated engine, it delivered power smoothly and predictably, without the complexity or lag associated with forced induction systems.

The engine produced a respectable 165 horsepower at 6000 rpm, which translated to a power per liter figure of 69.4 Hp/l. This output was more than adequate for a family-oriented station wagon, providing confident acceleration and effortless highway merging. Torque figures stood at 217 Nm (160.05 lb-ft) at a relatively accessible 4000 rpm, ensuring strong mid-range pull and responsiveness in everyday driving scenarios. The engine’s layout was front and transverse, a common and efficient design for front-wheel-drive vehicles, optimizing cabin space and weight distribution.

Power was transmitted to the front wheels via a precise 5-speed manual transmission. This gearbox allowed the driver to fully utilize the engine’s power band, offering an engaging driving experience that many enthusiasts appreciated. The front-wheel-drive architecture, coupled with a kerb weight of 3417.17 lbs (1550 kg), resulted in a weight-to-power ratio of 9.4 kg/Hp (106.5 Hp/tonne) and a weight-to-torque ratio of 7.1 kg/Nm (140 Nm/tonne). These figures indicated a well-proportioned vehicle capable of agile handling and respectable performance for its class and intended purpose as a versatile family hauler.

Engine Specifications Summary

The 2.4-liter engine boasted a compression ratio of 9.5:1, with a cylinder bore of 87 mm (3.43 in.) and a piston stroke of 100 mm (3.94 in.). These dimensions contributed to its smooth operation and robust power delivery. The DOHC valvetrain and multi-port injection system were key technological highlights, ensuring that the Legnum remained competitive in terms of engine efficiency and refinement during its production run.

Design and Features

The design of the Mitsubishi Legnum (EAO) 2.4i ST was characterized by its sleek and aerodynamic station wagon body, a distinct departure from the more traditional boxy wagons of previous generations. Its five-door, five-seat configuration emphasized practicality and versatility, making it an ideal choice for families or individuals requiring substantial cargo capacity without sacrificing aesthetic appeal. The Legnum’s exterior styling was contemporary for its time, featuring smooth lines, a distinctive front fascia shared with the Galant, and a rear design that seamlessly integrated the expanded cargo area.

Dimensionally, the Legnum measured 186.61 inches (4740 mm) in length, 69.29 inches (1760 mm) in width, and 57.87 inches (1470 mm) in height. Its generous 103.74-inch (2635 mm) wheelbase contributed to a stable ride and a spacious interior, particularly for rear-seat passengers. The front track of 60.04 inches (1525 mm) and a rear track of 59.84 inches (1520 mm) provided a solid stance and contributed to the vehicle’s handling characteristics. The maximum load capacity of 606.27 lbs (275 kg) and a fuel tank capacity of 15.85 US gallons (60 liters) further underscored its utility as a long-distance tourer or a capable hauler for everyday errands.

The Legnum’s chassis was designed for comfort and control. It featured an independent coil spring suspension system at both the front and rear, which was adept at absorbing road imperfections while maintaining composure during spirited driving. Braking performance was handled by ventilated discs at both the front and rear, providing strong and consistent stopping power.
