The Haima S7 (facelift 2017) 1.8 (188 Hp) Automatic represents a significant iteration of Haima’s foray into the compact SUV segment. Introduced in 2017, this version of the S7 aimed to bolster Haima’s presence in the rapidly growing Chinese automotive market. Positioned as a mid-range offering within the S7 lineup, it bridged the gap between the more basic trims and the potentially higher-equipped, though less common, variants. The facelift brought styling updates and, crucially, a more powerful turbocharged engine option paired with a six-speed automatic transmission, intended to appeal to buyers seeking a blend of practicality, comfort, and performance. The S7 itself is built upon Haima’s own platform, reflecting the company’s increasing independence in vehicle development.

Powertrain & Engine Architecture
The heart of the Haima S7 1.8 Automatic is the HM484Q-T, a 1.8-liter inline-four cylinder gasoline engine. This engine is turbocharged and features both intake and exhaust Variable Valve Timing (DVVT, iVVT), a technology designed to optimize engine performance and fuel efficiency across a wider range of engine speeds. The multi-port fuel injection system delivers fuel directly to the intake ports, contributing to efficient combustion. The engine produces 188 horsepower at 5500 rpm and 230 Nm (169.64 lb-ft) of torque between 1800 and 4500 rpm. This torque curve is relatively flat, providing usable power throughout the engine’s operating range. The engine is transversely mounted in the front of the vehicle. Paired with the engine is a six-speed automatic transmission. While not known for being particularly sporty, this transmission provides smooth shifts and contributes to the overall ease of driving. The transmission’s gear ratios are tuned for fuel economy and comfortable cruising, rather than outright acceleration.
Driving Characteristics
The driving experience in the Haima S7 1.8 Automatic is geared towards comfort and practicality. The 188 hp engine provides adequate power for everyday driving situations, including highway merging and overtaking. However, it doesn’t offer the brisk acceleration of some competitors with larger displacement or more powerful turbocharged engines. The automatic transmission contributes to a relaxed driving experience, particularly in city traffic. The suspension, featuring McPherson struts in the front and a multi-link setup in the rear, is tuned for ride comfort, absorbing bumps and imperfections in the road reasonably well. Steering feel is generally light and precise, making it easy to maneuver in urban environments. Compared to lower-powered S7 variants, the 1.8T Automatic offers a noticeable improvement in performance, making it a more enjoyable option for drivers who frequently travel on highways or carry passengers and cargo.
Equipment & Trim Levels
The Haima S7 1.8 Automatic typically came equipped with a reasonable level of standard features. These generally included air conditioning, power windows and locks, a basic audio system with USB connectivity, and ABS. Higher trim levels, often denoted by additional packages, could add features such as a touchscreen infotainment system, rearview camera, alloy wheels, and upgraded interior upholstery. Interior materials were generally of acceptable quality for the price point, with a focus on durability rather than luxury. The dashboard layout is functional and straightforward, with easy-to-reach controls. Optional extras often included a sunroof, leather seats, and parking sensors.
Chassis & Braking
The Haima S7 utilizes a front-wheel-drive chassis. The front suspension employs independent McPherson struts with coil springs and an anti-roll bar, while the rear suspension features an independent multi-link setup. This configuration aims to balance ride comfort with handling stability. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the vehicle’s weight and performance. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking situations. The steering system is a rack and pinion type with electric power steering, offering light and responsive steering feel.
Market Reception & Comparison
The Haima S7 1.8 Automatic was generally well-received in the Chinese market as a practical and affordable SUV option. Critics noted its comfortable ride, spacious interior, and improved performance compared to lower-powered variants. However, some reviewers pointed out that the interior materials and overall refinement were not on par with some of its more established competitors. Fuel economy was considered average for its class. Compared to other S7 trims, the 1.8T Automatic offered a significant performance upgrade, making it a more appealing choice for drivers who prioritized power and responsiveness. Its price point positioned it competitively against other compact SUVs from both domestic and international brands.
Legacy
The Haima S7 1.8 Automatic, while not a groundbreaking vehicle, played a role in establishing Haima as a credible player in the Chinese SUV market. The HM484Q-T engine, while not without its quirks, proved to be a relatively reliable powertrain when properly maintained. On the used car market, these S7s represent an affordable entry point into SUV ownership. Potential buyers should be aware of the importance of regular maintenance, particularly regarding the turbocharger and timing chain. Overall, the S7 1.8 Automatic remains a viable option for budget-conscious buyers seeking a practical and reasonably well-equipped compact SUV.
