Powertrain & Engine Architecture
The heart of the ASX 1.8 DI-D 4×4 is the 4N13 engine, a 1.8-liter inline-four cylinder diesel. This engine utilizes a common-rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for improved efficiency and reduced emissions. A turbocharger with an intercooler is employed to boost power output, providing 114 horsepower at 3500 rpm and a substantial 300 Nm (221 lb-ft) of torque between 1750 and 2250 rpm. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing gas flow for enhanced performance. The 6-speed manual transmission was standard, chosen for its balance of fuel economy and driver engagement. The engine is known for its relatively robust construction and ability to handle moderate tuning.
Driving Characteristics
The 1.8 DI-D 4×4 offered a practical and capable driving experience. While not a performance-oriented variant, the engine’s torque output provided adequate acceleration for everyday driving and highway cruising. The 0-60 mph time of around 10.1 seconds reflects this. The manual transmission allowed for precise control, and the all-wheel-drive system enhanced traction in various conditions, particularly on slippery surfaces. Compared to the petrol-powered ASX variants, the diesel offered significantly better fuel economy. However, it lacked the responsiveness of the higher-output engines available in the range. The gear ratios were tuned for fuel efficiency, meaning the engine could feel slightly strained when accelerating quickly or climbing steep hills.
Equipment & Trim Levels
The 1.8 DI-D 4×4 typically came equipped with a reasonable level of standard features. These included air conditioning, power windows, central locking, and an audio system with USB connectivity. Safety features such as ABS, electronic brakeforce distribution (EBD), and multiple airbags were also standard. Higher trim levels offered options like alloy wheels, a sunroof, rear parking sensors, and a more advanced infotainment system. Interior upholstery was typically cloth, with options for leather upgrades. The dashboard layout was functional and straightforward, prioritizing usability over luxury.
Chassis & Braking
The ASX I utilized a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and decent handling characteristics. The all-wheel-drive system employed a viscous coupling to distribute torque between the front and rear axles as needed. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The braking system was adequate for the vehicle’s weight and performance, with ABS providing enhanced stopping power and stability. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Mitsubishi ASX 1.8 DI-D 4×4 was generally well-received by automotive critics as a practical and fuel-efficient crossover. It was praised for its spacious interior, comfortable ride, and capable all-wheel-drive system. However, some reviewers noted that the engine could feel underpowered, especially when fully loaded. Compared to other diesel-powered crossovers in its class, such as the Nissan Qashqai and Volkswagen Tiguan, the ASX offered a competitive price point and a generous level of standard equipment. Fuel economy was a strong point, consistently achieving around 45-55 mpg in real-world driving conditions.
Legacy
The 4N13 engine, found in the ASX 1.8 DI-D, has proven to be a relatively reliable powertrain when properly maintained. Common issues include turbocharger wear and potential problems with the diesel particulate filter (DPF), particularly on vehicles that primarily see short-trip driving. On the used car market, the ASX 1.8 DI-D 4×4 represents a good value proposition for buyers seeking a practical and economical all-wheel-drive crossover. Its robust construction and relatively simple mechanicals make it a relatively affordable vehicle to maintain, although regular servicing is crucial to ensure long-term reliability. The model helped establish Mitsubishi as a key player in the European crossover segment.
