GM8 has a combined fuel consumption of 10.1L/100km. Below is the relevant information about the Trumpchi M8: Body dimensions: The dimensions of the Trumpchi GM8 are: length 5066mm, width 1923mm, height 1822mm, with a wheelbase of 3000mm. Model: The GAC Trumpchi GM8 is an MPV with a fuel tank capacity of 68L and a curb weight of 2002kg. Powertrain: The GAC Trumpchi GM8 features a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 201PS, maximum torque of 320Nm, and maximum power of 148kW, paired with a 6-speed automatic transmission.

My GM8 has been running for almost two years now, and it's particularly stable on long trips. The fuel consumption is indeed a bit higher in city traffic, showing around 12 liters per 100 kilometers on the dashboard when I drive. However, it drops immediately on the highway, cruising at 100 km/h generally consumes about 8.5 liters. Using the air conditioning adds roughly 0.5 liters to the consumption, especially during summer traffic jams when it's most fuel-intensive. The most fuel-efficient way to drive is to ease off the accelerator and avoid aggressive lane changes. With more passengers onboard, the fuel consumption increases by about 1 liter, especially when the trunk is fully loaded with luggage. Honestly, this fuel consumption is quite normal for such a large vehicle, and it's even slightly more economical than my neighbor Lao Zhang's GL8.

I mainly use the GM8 for intercity shuttle services, covering 300-400 kilometers daily, so I'm very clear about its fuel consumption. When running empty on highways, it averages 9.2 liters per 100km, but fully loaded with passengers and luggage, it goes up to around 10.5 liters. The manufacturer's claim is 8.7 liters – not far off on highways, but during urban rush hours, it can hit 14 liters. The 74-liter fuel tank gives a range of about 650km when full. My fuel-saving trick is using cruise control frequently. I change the engine oil every 5,000 kilometers religiously – fully synthetic oil seems to save 0.3 liters per 100km compared to semi-synthetic. Winter warm-ups increase consumption, but with current good weather, it stays between 9-10 liters.

The key to driving the GM8 efficiently lies in your footwork. Sudden braking and rapid acceleration will immediately spike the fuel consumption, while smooth driving can keep it under 9 liters on the highway. I've experimented with different engine oils, and fully synthetic oil does save more fuel compared to mineral oil. Maintaining tire pressure at 2.6 is optimal, as underinflated tires significantly increase fuel consumption. The eco-mode indicator on the rearview mirror is quite helpful; following its prompts can save a lot. I've tried both 92 and 95 octane fuels, and the actual fuel consumption difference is minimal. Taking expressways in the city is more fuel-efficient than regular roads, and your route in advance really helps. The most fuel-efficient state for this car is cruising at a steady 80 km/h, where it can achieve 7.8 liters.

The fuel consumption of the GM8 largely depends on how you maintain it. I check the tire pressure every month and refill them immediately if they're low, which can save half a liter of fuel. I regularly clean the air filter, as a clogged one affects air intake and significantly increases fuel consumption. In summer, I always open the windows for a few minutes before turning on the AC to reduce the engine's load. When the fuel consumption warning light on the rearview mirror comes on, I ease off the accelerator, and this habit has proven effective. Before hitting the highway, I always remove the spare tire, reducing the weight by 30 kg. I only refuel at reputable gas stations, as low-quality gasoline can cause a sharp increase in fuel consumption. After four years and 60,000 km, my car's combined fuel consumption remains stable at 10.2 L/100km.

Attention to friends to buy an MPV: The fuel consumption of the GM8 depends on specific usage scenarios. When I frequently take my whole family on trips, with all seven seats occupied and the air conditioning on while driving on the highway, it consumes about 10 liters per 100 km. For daily commuting in the city with just me driving, it's around 9 liters normally. The latest model has been upgraded with an 8AT transmission, which is nearly 1 liter more fuel-efficient than the older version. I recommend installing a fuel consumption monitoring app to understand in real-time how driving habits affect fuel efficiency. The tire pressure chart inside the fuel tank cap should be checked regularly—a difference of 0.3 in tire pressure can lead to a 5% difference in fuel consumption. The most cost-effective option is the hybrid version, which can achieve around 6 liters per 100 km in the city, though it's over 50,000 yuan more expensive than the gasoline version.
