The auto industry is abuzz with the arrival of the 2025 Second-Generation Haval Big Dog Hi4 Plug-in Hybrid SUV. This vehicle, manufactured by Great Wall Motor (GWM), showcases a powerful hybrid system and advanced driving assistance systems, making it a formidable contender in the plug-in hybrid SUV market.
Key Powertrain Features
At the heart of the Hi4 is a 1.5-liter turbocharged gasoline engine, producing around 156-167 PS, paired with two electric motors—one at the front and one at the rear. This combination results in a total system power of up to 449 horsepower (PS) and a maximum torque of 750 Nm.
The Hi4 system offers three lithium iron phosphate (LFP) battery packs, providing pure electric ranges of approximately:
- 18.7 kWh battery: 81 km (WLTC)
- 27.5 kWh battery: 115 km (WLTC)
- 35.4 kWh battery: 151 km (WLTC)
The powertrain is equipped with a two-speed dedicated hybrid transmission (DHT), managing power delivery at the front axle. The smaller battery variant accelerates from 0 to 100 km/h in around 6.0 seconds, while the larger battery variant, which is heavier, takes slightly longer at 6.2 seconds.
The Hi4 Intelligent Torque Vectoring system dynamically distributes torque between the front and rear axles every 10 milliseconds, enhancing grip and reducing slippage by 50% on low-friction surfaces like ice and snow.
The system also includes a rear-axle electronic differential lock and offers seven driving modes for versatile terrain handling. At speeds above 70 km/h, the rear motor disconnects automatically to reduce friction losses and fuel consumption by 0.4 to 0.7 L per 100 km, with re-engagement occurring within milliseconds.
Advanced Driving Assistance Systems
The Hi4's advanced driving assistance systems incorporate a new ice and snow algorithm, improving torque prediction and accuracy by 6.5% and reducing mode switching time by 25% during wheel slippage. This indicates sophisticated real-time monitoring and adaptation, improving safety and traction control in adverse weather or low-grip road conditions.
Additional Details
Design updates include a smaller brand logo with an illuminated LED strip, similar to the latest Haval Big Dog styling cues. The focus on hybrid AWD performance and electric-only range makes this SUV competitive in the plug-in hybrid SUV market segment in China and potentially other markets.
Inside the cockpit, the Second-Generation Haval Big Dog Hi4 boasts a 14.6-inch central control screen, a 12.3-inch full LCD instrument panel, a HUD (head-up display), a four-spoke steering wheel, and a row of physical buttons below the central control screen.
The lithium iron phosphate battery pack provides a pure electric cruising range of 102 km (NEDC). The truck volume can be expanded to 1,362 L after the rear row is folded down. The maximum power of the front and rear motors is 70 kW and 150 kW, respectively.
The SUV supports seven driving modes including economy, sports, mud, and sand. The size of the car is 4705/1908/1780 mm, and the wheelbase is 2810 mm. DC fast charging is supported for the Haval Second-Generation Big Dog Hi4.
The new car's front face is designed with a matrix structure polygonal grille and round headlights. The powertrain consists of a 1.5T engine (GW4B15E) and dual motors, mated to a 2-speed DHT. The Haval Second-Generation Big Dog Hi4 is powered by Great Wall Motor's Hi4 plug-in hybrid system.
The Haval Second-Generation Big Dog Hi4 Plug-in Hybrid SUV is now available in markets with a price of 179,800 yuan (approximately 24,900 USD). With its powerful hybrid system, advanced driving assistance systems, and competitive pricing, this vehicle is sure to turn heads and raise the bar in the plug-in hybrid SUV market.
