Are the engines of the new and old Haval M6 models the same?
4 Answers
Haval M6's new and old models do not have the same engine. The 1.5T turbocharged engine equipped on the Haval M6 is the same as the 1.5T engine on the old H6 model, with the model number GW4G15B, a maximum power of 110kW/5600rpm, and a maximum torque of 210N·m/2200-4500rpm. In terms of the transmission system, it is matched with a 6-speed automatic transmission from Hyundai Group. Below is additional information: 1. Introduction to Haval M6: As the first compact model of the Haval M series, the Haval M6 is positioned as a cost-effective family compact SUV. The first model was launched on July 21, 2017. Designed by an international design team, the new car showcases its fashionable side under the premise of 'simple, refined, and safe' styling design, making it a 360° fashion icon in the compact SUV segment. 2. Hardware Configuration: The interior continues the classic design of the Haval family. The wing-shaped center console, designed with the concept of 'simple and practical,' perfectly matches the classic three-spoke multifunctional steering wheel. The intelligent combination instrument panel is paired with an 8-inch LCD central control display screen, making all functions easily accessible and reflecting humanized care.
I've compared the spec sheets of the old and new Haval M6 models, and indeed the engines are different. The older version still used the classic 1.5T engine coded GW4G15B, while the new model switched to the GW4G15M engine after 2021. The new engine features CVVL (Continuous Variable Valve Lift) technology, maintaining around 150 horsepower but delivering significantly improved low-speed torque, making it much more responsive to drive. Maintenance costs are roughly similar, though the new engine has slightly higher fuel requirements, with 95-octane gasoline recommended. Another detail is the optimized ECU programming - the older model often felt jerky in congested traffic due to transmission hesitation, while gear shifts in the new version are noticeably smoother.
Last week, my brother-in-law picked up the new M6, and I specifically compared it with their old model. The old version had an orange label in the engine bay, while the new one has a blue label. The biggest change is that the new engine uses an electronically controlled turbocharger, making turbo lag much less noticeable when stepping on the gas. We used an OBD device to test the data: the old model reached maximum torque at 1,500 rpm, while the new one delivers peak torque at 1,300 rpm. This difference is particularly noticeable when climbing hills. In terms of fuel consumption, the new model saves about 0.8L/100km in city driving. When buying used, pay special attention to this dividing line—cars from 2019 and 2020 can easily be confused.
Helped a friend inspect a used car and found a key point: M6 models before December 2019 used the old engine, while those after March 2020 mostly have the new version. The old engine cover is made of silver cast iron, whereas the new one is replaced with black aluminum alloy—you can tell just by opening the hood. The new engine relocated the water pump, making it easier to service the coolant hoses. However, the intake pipe design has changed, so you’ll need a new kit if you want to install a performance air filter. Real-world testing shows the new engine has quieter cold starts, but at highway speeds, the RPMs don’t drop as much, likely because the power tuning prioritizes everyday driving comfort.
