ZX Landmark 2.4 (126 Hp) 4×2 Automatic

The ZX Landmark 2.4 (126 Hp) 4×2 Automatic was a rear-wheel drive sport utility vehicle (SUV) produced by ZX between 2006 and 2009. Positioned as a mid-range offering within the Landmark lineup, it catered to buyers seeking a spacious, seven-seat vehicle with the convenience of an automatic transmission. This variant occupied a space between the more basic, lower-powered models and potential future higher-specification trims, offering a balance of affordability and practicality. The Landmark series was built upon a body-on-frame chassis, a construction method common in SUVs of the era, prioritizing durability and off-road capability, though this specific 4×2 model was geared more towards on-road use.

Powertrain & Engine Architecture

The heart of the ZX Landmark 2.4 Automatic is the Mitsubishi-sourced 4G64 S4M inline-four cylinder gasoline engine. This 2.4-liter (2351 cm³ or 143.47 cu. in.) engine produces 126 horsepower at 5200 rpm and 193 Nm (142.35 lb.-ft.) of torque at 3000 rpm. The engine features a compression ratio of 9.5:1 and utilizes a multi-port fuel injection system for efficient fuel delivery. The valvetrain is a double overhead camshaft (DOHC) design with four valves per cylinder, contributing to improved breathing and power output. The engine’s power per liter is rated at 53.6 hp/l.

The engine is mated to a four-speed automatic transmission. While not the most modern transmission technology available at the time, it provided smooth and convenient gear changes, appealing to a broader range of drivers. The transmission’s gear ratios were optimized for everyday driving conditions, prioritizing fuel efficiency and comfortable cruising over outright performance. Specific gear ratios are not widely documented, but the four-speed configuration suggests a focus on usability rather than maximizing acceleration.

Driving Characteristics

The ZX Landmark 2.4 Automatic offered a comfortable, if not particularly sporty, driving experience. With 126 hp propelling a relatively heavy vehicle (1710 kg or 3769.9 lbs. kerb weight), acceleration was adequate for everyday driving but not brisk. The 0-60 mph time was likely in the 12-14 second range. The automatic transmission contributed to a smooth driving experience, but it also resulted in some power loss compared to a manual transmission variant, had one been offered. The rear-wheel drive configuration provided decent traction in most conditions, but it lacked the all-weather capability of a four-wheel drive system.

The four-speed automatic transmission, while providing convenience, limited the engine’s ability to stay in its optimal power band. The gear ratios were spaced to prioritize fuel economy and smooth cruising, meaning the engine often felt strained during quick acceleration or when climbing hills. Compared to potential higher-output versions (which were not produced), the 2.4L automatic offered a more relaxed and economical driving experience, sacrificing performance for practicality.

Equipment & Trim Levels

The ZX Landmark 2.4 Automatic came standard with a reasonable level of equipment for its price point. Standard features typically included air conditioning, power windows, power steering (hydraulic), and an anti-lock braking system (ABS). The interior was typically upholstered in cloth, with a functional, if somewhat basic, dashboard layout. The seven-seat configuration provided ample space for passengers, making it a practical choice for families.

Optional extras available for the Landmark 2.4 Automatic could include alloy wheels, a radio/CD player, and potentially upgraded interior trim options. The availability of these options varied depending on the specific market and dealer.

Chassis & Braking

The ZX Landmark 2.4 Automatic utilized a body-on-frame construction, providing a robust and durable chassis. The front suspension consisted of torsion bars, while the rear suspension employed leaf springs. This suspension setup prioritized load-carrying capacity and durability over refined handling. The front brakes were discs, providing adequate stopping power, while the rear brakes were drums, a cost-saving measure common in vehicles of this class. The tires were typically 235/70 R16, mounted on 7J x 16 inch wheel rims.

Market Reception & Comparison

The ZX Landmark 2.4 Automatic was generally well-received as a practical and affordable SUV. Critics noted its spacious interior, comfortable ride, and reasonable fuel economy (13 l/100 km combined, 18.1 US mpg, 21.7 UK mpg, 7.7 km/l). However, it was also criticized for its lack of performance and its somewhat dated automatic transmission. Compared to other SUVs in its class, the Landmark 2.4 Automatic offered a competitive price point and a generous amount of space, but it lacked the refinement and performance of some of its rivals.

In terms of reliability, the Mitsubishi 4G64 engine is generally considered to be a durable and reliable unit, provided it is properly maintained. The automatic transmission, however, could be prone to issues if not serviced regularly. The Landmark’s Euro 2 emission standard was relatively lenient for the time, but it may be a concern in areas with stricter emissions regulations.

Technical Specifications

Legacy

The ZX Landmark 2.4 Automatic, while not a particularly groundbreaking vehicle, served as a practical and affordable SUV for families and individuals seeking a spacious and reliable mode of transportation. Today, these vehicles can be found on the used car market at relatively low prices. The Mitsubishi 4G64 engine continues to be regarded as a durable and relatively easy-to-maintain powerplant. However, potential buyers should be aware of the age of the vehicle and the potential for wear and tear on the automatic transmission and suspension components. Proper maintenance records are crucial when considering a used ZX Landmark 2.4 Automatic. Its simplicity and relatively robust construction mean that, with care, these vehicles can continue to provide reliable service for years to come.
