Powertrain & Engine Architecture
The Haval Xiaolong Max Hi4 utilizes a sophisticated plug-in hybrid system. The core of the powertrain is the GW4B15H 1.5-liter inline-four cylinder naturally aspirated gasoline engine. This engine produces 116 horsepower and 140 Nm of torque. It features direct fuel injection and a Start & Stop system for improved efficiency. The engine is paired with a Dedicated Hybrid Transmission (DHT), a two-speed automatic transmission designed to seamlessly integrate with the electric motors. The DHT allows for efficient power delivery and optimized fuel consumption. Two electric motors are employed: a 95 hp motor driving the front wheels and a more powerful 204 hp motor powering the rear wheels, resulting in a combined system output of 279 horsepower and 585 Nm of torque. The 19.27 kWh lithium nickel manganese cobalt oxide (Li-NMC) battery pack is positioned under the floor, providing an all-electric range of 83 kilometers (51.57 miles) according to WLTC standards.
Driving Characteristics
The Hi4’s dual-motor all-wheel-drive system provides confident traction and handling in various conditions. In electric mode, the vehicle offers near-silent operation and brisk acceleration, particularly in urban environments. The DHT transmission is tuned for smooth transitions between electric and gasoline power, minimizing any noticeable shift shock. The two-speed nature of the DHT allows for optimized efficiency at cruising speeds and strong acceleration when needed. Compared to versions of the Xiaolong Max with solely internal combustion engines, the Hi4 offers significantly improved fuel economy and a more refined driving experience. While the 1.5-liter engine isn’t particularly powerful on its own, the combined output of the hybrid system delivers competitive performance within its class. The all-wheel drive system enhances stability and control, especially on slippery surfaces.
Equipment & Trim Levels
The Haval Xiaolong Max Hi4 is generally well-equipped, reflecting its positioning as a modern and technologically advanced SUV. Standard features typically include a large touchscreen infotainment system with smartphone connectivity, a digital instrument cluster, automatic climate control, and a comprehensive suite of safety features such as ABS, electronic stability control, and multiple airbags. Higher trim levels add features like leather upholstery, a panoramic sunroof, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane-keeping assist, and premium audio systems. The interior design emphasizes a clean and modern aesthetic, with high-quality materials and comfortable seating.
Chassis & Braking
The Xiaolong Max Hi4 utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride and responsive handling. The suspension is tuned to balance ride comfort with body control. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The electric power steering system offers precise and responsive steering feel. The vehicle’s relatively low center of gravity, thanks to the underfloor battery pack, contributes to its stability and handling characteristics. The 235/55 R19 tires provide a good balance between grip and ride comfort.
Market Reception & Comparison
The Haval Xiaolong Max Hi4 has been well-received in the Chinese market, where demand for plug-in hybrid vehicles is rapidly growing. Critics have praised its fuel efficiency, all-electric range, and comfortable driving experience. Compared to other plug-in hybrid SUVs in its class, the Xiaolong Max Hi4 offers a competitive combination of performance, features, and price. Its all-wheel-drive system is a notable advantage over some rivals that offer only front-wheel drive. The vehicle’s fuel economy of 1.78 l/100 km is significantly better than that of comparable gasoline-powered SUVs. Reliability data is still emerging, but Haval has been steadily improving the quality and reliability of its vehicles in recent years.
Legacy
The Haval Xiaolong Max Hi4 represents a significant step forward for Haval in the development and production of new energy vehicles. Its advanced plug-in hybrid technology and all-wheel-drive system demonstrate Haval’s commitment to innovation and sustainability. As the Chinese automotive market continues to shift towards electrification, the Xiaolong Max Hi4 is poised to become a popular choice for consumers seeking a fuel-efficient, technologically advanced, and practical SUV. The long-term reliability of the powertrain remains to be seen, but the use of proven components and Haval’s ongoing efforts to improve quality suggest a positive outlook. The Hi4’s success will likely influence Haval’s future product development and accelerate the adoption of plug-in hybrid technology in the Chinese market.
