Powertrain & Engine Architecture
The Haval Xiaolong’s powertrain centers around the 4G15H 1.5-liter inline-four cylinder naturally aspirated gasoline engine. This engine produces 101 horsepower and 132 Nm of torque. It utilizes a multi-port fuel injection system, a common setup for maximizing fuel efficiency in this class of vehicle. The engine is paired with a 9.41 kWh Lithium Iron Phosphate (LiFePO4) battery pack, positioned under the floor of the vehicle to optimize space. The electric motor, a synchronous type, delivers 156 horsepower and 250 Nm of torque. The combined system output is a respectable 252 horsepower and 375 Nm of torque. The key to the Xiaolong’s hybrid functionality is Haval’s Dedicated Hybrid Transmission (DHT). This transmission, featuring only two gears, isn’t designed for traditional shifting but rather for seamlessly blending power from the engine and electric motor, optimizing efficiency and responsiveness. The DHT system allows for all-electric driving for up to 45 kilometers (27.96 miles) based on the WLTC cycle.
Driving Characteristics
The Xiaolong 1.5L PHEV offers a driving experience geared towards comfort and efficiency. The two-gear DHT transmission prioritizes smooth acceleration and minimizes engine noise, particularly during low-speed urban driving where the vehicle can operate in all-electric mode. Compared to potential gasoline-only versions of the Xiaolong, the PHEV variant provides significantly improved low-end torque thanks to the instant response of the electric motor. While not a performance-oriented vehicle, the combined 252 horsepower provides adequate power for everyday driving and highway merging. The automatic transmission is tuned for fuel economy, meaning it may not offer the same level of driver engagement as a traditional multi-gear automatic or a manual transmission. The steering is light and precise, making it easy to maneuver in city traffic.
Equipment & Trim Levels
Specific trim levels and standard equipment for the Haval Xiaolong 1.5L PHEV can vary depending on the market and optional packages selected. However, generally, this variant includes features such as automatic climate control, a touchscreen infotainment system with smartphone connectivity, keyless entry, and a suite of safety features including ABS, electronic stability control, and multiple airbags. Interior upholstery typically consists of cloth or synthetic leather, with higher trims offering genuine leather options. Optional extras may include a panoramic sunroof, upgraded audio system, and advanced driver-assistance systems (ADAS) like adaptive cruise control and lane keeping assist.
Chassis & Braking
The Haval Xiaolong utilizes an independent McPherson strut suspension setup at the front and an independent multi-link suspension at the rear, providing a comfortable ride quality and good handling characteristics. The front brakes are ventilated discs, offering good stopping power, while the rear brakes are solid discs. The electric power steering system provides a light and responsive feel. The vehicle is equipped with ABS (Anti-lock Braking System) as standard, enhancing safety during emergency braking situations. The 18-inch alloy wheels, fitted with 225/60 R18 tires, contribute to both the vehicle’s aesthetics and its on-road grip.
Market Reception & Comparison
The Haval Xiaolong 1.5L PHEV has been well-received in the Chinese market, where it competes with other compact PHEV SUVs from both domestic and international manufacturers. Critics have praised its fuel efficiency, comfortable ride, and relatively spacious interior. Compared to other trims in the Xiaolong lineup, the PHEV variant offers a significant advantage in fuel economy and reduced emissions. However, it typically comes at a higher price point than the gasoline-only models. Its fuel economy of 2.4 l/100 km is competitive within the PHEV segment, and its all-electric range of 45 km is sufficient for many daily commutes.
Legacy
As a relatively new model, the long-term reliability of the Haval Xiaolong 1.5L PHEV is still being established. However, Haval has been steadily improving the quality and reliability of its vehicles in recent years. The LiFePO4 battery technology used in the Xiaolong is known for its stability and long lifespan. The DHT transmission, while unconventional, has proven to be relatively reliable in other Haval models. In the used car market, the Xiaolong 1.5L PHEV is expected to hold its value reasonably well, particularly as demand for electric and hybrid vehicles continues to grow. Its combination of fuel efficiency, practicality, and modern features should make it an attractive option for buyers seeking a well-rounded compact SUV.
