As an early Haval owner, the first-generation Haval H6 gasoline version's main model was equipped with Mitsubishi's 4G63 engine, the 2.0L displacement one. Back then, you could still see the big logo on the engine cover. The diesel version used Great Wall's own GW4D20 diesel engine, which was a bit noisy but had plenty of power. I remember when it was first launched in 2011, these were basically the only two options. It wasn't until the minor facelift that they switched to Great Wall's self-developed 1.5T engine, but by then it was considered the second generation. If you pop the hood of an early H6 still on the road today, chances are you'll spot that Mitsubishi red-top engine.

With a decade of experience repairing hundreds of Haval vehicles, the first-generation H6 gasoline engines came in two variants: The primary one was the Shenyang Aerospace 4G63S4M, a 2.0L naturally aspirated engine, most commonly found in models with VINs starting with LF. Later, some 2012 models used Mitsubishi's 4G69 2.4L engine. The diesel versions uniformly featured Great Wall's self-developed GW4D20 Green Quiet engine, which was turbocharged. Here's a handy tip: Open the hood and check the left-side nameplate—the 6th digit of the 4G63 engine number is usually a G. While these older engines aren't cutting-edge in technology, their maintenance is affordable, with timing belt replacements costing just a few hundred yuan.

From the technical documentation, the engine configurations of the first-generation 2011-2014 Haval H6 were quite characteristic of their era: the base model used the 4G63S4M inline-four engine, featuring a cast iron block paired with an aluminum alloy cylinder head and a SOHC valve train. The higher-end variant briefly experimented with the 2.4L 4G69 version, but the sales leader remained the 2.0L. The diesel-powered GW4D20 utilized BOSCH high-pressure common rail technology, delivering 310N·m of torque at just 1600 rpm. Notably, a 1.5T turbocharged engine (coded GW4G15B) was added during the 2013 facelift, which later became the flagship powerplant for the second generation.

Back when I was selling cars at a 4S dealership, customers always asked about engine specs. The first-gen H6's 2.0L gasoline engine delivered 98kW max power – acceleration was indeed sluggish, but it ran reliably on 92-octane fuel. The diesel version was actually more popular, especially with bosses who loved the GW4D20 diesel engine for its strong low-end torque and fuel efficiency. The most interesting case was in 2012 when some automatic models equipped with Mitsubishi 4G69 engines surprisingly achieved better fuel economy than manuals, thanks to excellent transmission tuning. Nowadays in the used car market, if you find a first-gen diesel model with over 200,000 km, its engine condition often outlasts gasoline counterparts of the same era.

A veteran driver who took the first-gen H6 to Tibet tells you that the 4G63 engine actually performs steadily at high altitudes. Although the RPM often hits 4000 when climbing slopes, it rarely breaks down as long as you change the oil on time. The 2011 model had a common issue with the intercooler design - it tended to overheat when climbing long slopes with AC on in summer, which was later fixed by a recall that added air deflectors. Remember to pay special attention to fuel quality for the diesel version - repairing the high-pressure fuel pump costs over 5,000 yuan. But frankly speaking, for those first-gen H6s still running on the road today, some oil seepage from the engine hood gaps is considered normal. Real capability lies in being classic and durable.
