Powertrain & Engine Architecture
The Haval H6 III 1.5T PHEV utilizes a sophisticated plug-in hybrid powertrain. The core of the system is the GW4B15D 1.5-liter inline-four cylinder gasoline engine. This engine features direct fuel injection and a turbocharger with an intercooler, enabling it to produce 154 horsepower and 233 Nm (171.85 lb.-ft.) of torque. The engine is paired with a 177 horsepower electric motor integrated into the Dedicated Hybrid Transmission (DHT), a two-speed automatic transmission developed by Haval. This DHT system allows for seamless switching between electric, hybrid, and gasoline power modes. The 19.9 kWh lithium-ion battery pack, positioned under the vehicle floor, provides an all-electric range of 86 km (53.44 miles) according to WLTC standards. The engine employs a Variable Geometry Turbocharger (VGT) to optimize performance across a wider range of engine speeds.
Driving Characteristics
The H6 III 1.5T PHEV offers a refined driving experience. In pure electric mode, the vehicle provides near-silent operation and instant torque, resulting in brisk acceleration. The DHT transmission, with its two gear ratios, is optimized for efficiency and smooth power delivery. In hybrid mode, the gasoline engine and electric motor work in tandem, providing a combined output of 326 horsepower and 530 Nm (390.91 lb.-ft.) of torque. This allows for confident acceleration and effortless highway cruising. Compared to non-hybrid H6 variants, the PHEV model offers improved fuel economy and reduced emissions. While the added weight of the battery pack slightly impacts handling, the independent suspension system provides a comfortable and controlled ride.
Equipment & Trim Levels
The Haval H6 III 1.5T 19.9 kWh PHEV typically came well-equipped, even in its base trim levels. Standard features often included a large touchscreen infotainment system with smartphone connectivity, a digital instrument cluster, leather upholstery, automatic climate control, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and automatic emergency braking. Higher trim levels added features like a panoramic sunroof, premium audio system, and ventilated front seats. The interior design emphasized a modern and spacious feel, with high-quality materials and attention to detail.
Chassis & Braking
The H6 III utilizes a front-wheel-drive layout. The chassis features an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride and good handling characteristics. The braking system consists of ventilated discs at the front and solid discs at the rear, coupled with an Anti-lock Braking System (ABS) to enhance safety. The electric power steering system offers precise and responsive steering feel. The vehicle rides on 19-inch alloy wheels with tires sized 235/55 R19.
Market Reception & Comparison
The Haval H6 III 1.5T PHEV was generally well-received in the Chinese market, where it competed with other plug-in hybrid SUVs from both domestic and international brands. Critics praised its fuel efficiency, electric range, and advanced technology features. Compared to the standard gasoline-powered H6 models, the PHEV variant offered a significant improvement in fuel economy and a more refined driving experience. However, the higher price point and added weight were noted as potential drawbacks. Compared to other PHEV SUVs in its class, the H6 III offered a competitive combination of performance, features, and value.
Legacy
The Haval H6 III 1.5T 19.9 kWh PHEV represents a significant step forward in Haval’s development of new energy vehicles. The DHT powertrain technology and plug-in hybrid system demonstrate Haval’s commitment to innovation and sustainability. While production of this specific variant ended in April 2024, the H6 model continues to be a popular choice in the Chinese market, and the technologies developed for this PHEV version are likely to be incorporated into future Haval vehicles. On the used car market, these models are becoming increasingly sought after by buyers looking for a fuel-efficient and technologically advanced SUV.
