The Mitsubishi Legnum (EAO) represents a significant chapter in the Japanese automaker’s history, specifically designed as the station wagon variant of the eighth-generation Galant sedan. Produced from 1997 to 2002, the Legnum (EAO) was primarily targeted at the Japanese Domestic Market (JDM), with limited availability in select international markets such as Australia and parts of Europe, where its combination of practicality and dynamic styling found an appreciative audience. Unlike its sedan counterpart, which was more widely exported, the Legnum maintained a distinct identity, catering to families and individuals who required greater cargo capacity without sacrificing driving engagement. The 2.4i ST (165 Hp) Automatic model, the focus of this article, offered a compelling blend of a capable four-cylinder engine, a smooth automatic transmission, and the inherent versatility of a station wagon body, establishing itself as a reliable and well-equipped contender in its segment.
Mitsubishi Legnum (EAO): A JDM Wagon
The Mitsubishi Legnum, designated as the EAO series, was conceived as the wagon derivative of the Galant, offering a practical alternative for buyers seeking increased cargo space. It occupied the mid-size segment, competing with other Japanese wagons and offering a blend of comfort, reliability, and a degree of sporting character. While not officially sold in the United States, the Legnum found a following in Japan, Australia, and select European markets, appealing to those who valued a versatile vehicle with a more engaging driving experience than typically found in conventional wagons.
Engine & Performance: The 2.4-Liter Powertrain
The Mitsubishi Legnum (EAO) 2.4i ST is powered by a 2.4-liter (2378 cc) inline-four cylinder engine. This engine, a hallmark of Mitsubishi’s engineering during the late 1990s, utilizes a Double Overhead Camshaft (DOHC) configuration with four valves per cylinder. This design optimizes airflow, contributing to both efficient combustion and a broad powerband. The engine features a compression ratio of 9.5:1 and employs a multi-port fuel injection system for precise fuel delivery.
Producing 165 horsepower at 6000 rpm, the engine provides adequate power for everyday driving and longer journeys, even when the vehicle is fully loaded. Torque output is rated at 217 Nm (160.05 lb-ft), peaking at 4000 rpm, delivering responsive acceleration and sufficient pulling power for a family-oriented vehicle. The front, transverse engine layout, coupled with a front-wheel-drive drivetrain, contributes to predictable handling and maximizes interior space. Power is transmitted to the front wheels via a smooth-shifting 4-speed automatic transmission, prioritizing comfort and ease of use. The Legnum 2.4i ST boasts 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), resulting in a spirited driving experience for its class.
Design & Features: Practicality and Styling
The Mitsubishi Legnum (EAO) is a five-door station wagon designed to maximize cargo versatility. Its exterior styling shares design cues with the Galant sedan, featuring sleek lines and a contemporary profile that distinguishes it from more traditional wagon designs. The vehicle measures 186.61 inches (4740 mm) in length, 69.29 inches (1760 mm) in width, and 57.87 inches (1470 mm) in height, providing a substantial road presence. A wheelbase of 103.74 inches (2635 mm) contributes to a stable ride and ample interior space for five passengers.
The interior of the Legnum prioritizes practicality and comfort, typical of Japanese vehicles from this era. Ample storage solutions and a well-organized dashboard layout enhance usability. The vehicle’s kerb weight of 3417.17 lbs (1550 kg) reflects its solid construction and contributes to a sense of stability. The suspension system utilizes coil springs at both the front and rear, providing a balanced ride quality that effectively absorbs road imperfections while maintaining composure during cornering. Ventilated disc brakes on all four wheels enhance stopping power and reduce brake fade, particularly important when carrying heavy loads. An Anti-lock Braking System (ABS) is standard, providing increased stability during emergency braking maneuvers. The rack and pinion steering system, assisted by hydraulic power steering, offers ease of maneuverability at low speeds and a connected feel at highway speeds. The vehicle is equipped with 16-inch wheels fitted with 225/50 R16V tires, providing a balance of grip and ride comfort.
