Powertrain & Engine Architecture
The Haval H6 III 1.5T HEV DHT utilizes a 1.5-liter turbocharged inline-four cylinder gasoline engine (GW4B15D) paired with an electric motor and a dedicated hybrid transmission (DHT – Dedicated Hybrid Transmission). The gasoline engine produces 154 horsepower and 233 Nm (171.85 lb-ft) of torque. Direct fuel injection and a variable geometry turbocharger (VGT) contribute to both power output and efficiency. The electric motor generates 177 horsepower and 300 Nm (221.27 lb-ft) of torque. The combined system output is rated at 243 horsepower and 530 Nm (390.91 lb-ft) of torque. The DHT transmission, a key component of the system, is a two-speed automatic designed to seamlessly blend power from the engine and electric motor, optimizing for efficiency or performance as needed. The 1.8 kWh lithium-ion battery pack is located under the floor, minimizing impact on passenger space.
Driving Characteristics
The 1.5T HEV DHT offers a noticeably different driving experience compared to the standard gasoline-only H6 models. The electric motor provides instant torque, resulting in brisk acceleration, particularly from a standstill. The DHT transmission contributes to smooth transitions between electric and gasoline power, and the two-speed configuration is geared for both efficient cruising and responsive acceleration. While not a performance-oriented SUV, the combined 243 hp provides adequate power for everyday driving and highway merging. Compared to higher-output gasoline engines available in the H6 range, this hybrid variant prioritizes fuel economy and refinement over outright speed. The front-wheel-drive configuration provides predictable handling, though it lacks the all-wheel-drive capability of some other H6 trims.
Equipment & Trim Levels
The 1.5T HEV DHT trim typically includes a comprehensive suite of standard features. These commonly include leather upholstery, a large touchscreen infotainment system with smartphone integration (Apple CarPlay and Android Auto), a panoramic sunroof, automatic climate control, and a range of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras often include upgraded sound systems, ventilated front seats, and a 360-degree camera system. Interior design emphasizes a modern aesthetic with a focus on comfort and technology.
Chassis & Braking
The Haval H6 III utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride quality. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard, enhancing safety and control. The chassis is designed to balance ride comfort with handling stability, catering to a broad range of driving conditions.
Market Reception & Comparison
The Haval H6 III 1.5T HEV DHT has been well-received in the Chinese market, where demand for hybrid and electric vehicles is rapidly growing. Critics have praised its fuel efficiency, smooth powertrain, and comprehensive feature set. Compared to the standard gasoline-powered H6 models, the HEV variant offers significantly improved fuel economy, albeit at a slightly higher purchase price. Compared to other hybrid SUVs in the Chinese market, the H6 HEV offers a competitive combination of price, features, and performance. Reliability reports are still emerging, but early indications suggest that the powertrain is proving to be reasonably durable.
Legacy
The Haval H6 III 1.5T HEV DHT represents Haval’s commitment to developing more fuel-efficient and environmentally friendly vehicles. The DHT transmission technology is expected to be rolled out to other models within the Haval lineup. As the used car market matures, this variant is likely to be sought after for its fuel economy and relatively advanced technology. The long-term reliability of the hybrid powertrain will be a key factor in its continued success and resale value. The H6 III, and specifically this HEV variant, is helping to establish Haval as a significant player in the global SUV market.
