Different SUVs have varying fuel consumption due to differences in their engines, transmission tuning, and vehicle weight, making it difficult to specify an exact figure. Generally speaking, for most family-oriented SUVs with engine displacements typically ranging from 1.6 to 2.0 liters and equipped with automatic transmissions, the actual fuel consumption is around 10 liters per 100 kilometers. On long highway trips, fuel consumption may drop to 7-8 liters per 100 kilometers, while urban commuting with traffic congestion often exceeds 10 liters per 100 kilometers. This represents a fairly common range of fuel consumption. Factors affecting fuel consumption: While engine displacement has some correlation with fuel consumption, larger displacement does not always mean higher fuel usage. Relatively speaking, the size of a car's engine displacement does not directly proportionally relate to its fuel consumption. Besides displacement, factors such as the vehicle's aerodynamics, weight, and engine technology also significantly influence fuel efficiency. Among vehicles with the same displacement, those with more advanced engine technology tend to be more fuel-efficient.

Last time I took my brother's compact SUV on a long-distance trip and specifically measured the fuel consumption. With the 1.5T engine paired with a CVT transmission, it averaged around 7.5 liters when cruising at 120 km/h on the highway, but during morning and evening rush hour traffic, it shot up to over 10 liters. The mechanic said that for an SUV of this size, a combined fuel consumption of 8-10 liters is considered reasonable. If it had a 2.0T engine or a four-wheel-drive system, it would typically consume 10-12 liters. I once drove a friend's Highlander Hybrid, and it was very fuel-efficient, only about 6 liters in the city. Indeed, newer technology can save a lot of fuel. I recommend calculating the actual fuel consumption when refueling; it's more accurate than the displayed value.

Our fleet has been transporting goods on plateaus for years, so we're very familiar with SUV fuel consumption. For popular models like the Haval H6, fuel consumption is around 9 liters with air conditioning on in plain areas, but it increases by at least 2 liters when driving above 4,000 meters in altitude. Vehicle load also has a significant impact – I've tested that a fully loaded rear seat with tools consumes 1.5 liters more than an empty vehicle. Also, never overlook tire pressure. Last time when the tire pressure dropped to 2.0, it directly increased fuel consumption by 0.8 liters per 100 kilometers. Newer models are generally more fuel-efficient than those from ten years ago. My old 2013 Tiguan can still maintain around 11 liters, and timely replacement of spark plugs and air filters is particularly crucial.

Recently compared fuel consumption data of three mainstream SUVs: Honda CR-V hybrid tested at 5.8L, Tiguan L 330TSI combined 9.2L, and Highlander 2.0T requiring 10.5L. Discovered several patterns: every 100kg increase in vehicle weight consumes approximately 0.5L more fuel; part-time 4WD saves about 15% fuel compared to full-time 4WD; 48V mild hybrid systems can indeed save around 8% fuel. It's recommended to pay attention to WLTC cycle values when selecting a car, as they are more realistic than the old NEDC standards. For example, two cars both rated at 8L may actually differ by 2L in real-world driving.
