The comprehensive fuel consumption (L/100km) as per the Ministry of Industry and Information Technology is 7.2. Below is relevant information: 1. Exterior: breaks traditional design concepts by combining the spindle grille and flared fenders to emphasize the UX's non-conformist character, while flexible performance and outstanding maneuverability are further highlighted through aerodynamic body design and blade-style headlights composed of 120 LED lights. 2. Configuration: The Cadillac XT4 is equipped with the eighth-generation Ecotec 2.0T engine, with the most notable feature being the Tripower variable valve management technology. Many people may not be very familiar with this variable valve management technology.

















I drove my friend's XT4 for over half a year. In city traffic jams, the displayed fuel consumption can soar to over 10L, but it's quite fuel-efficient on highways, around 7L with the AC on. The car's 2.0T engine with cylinder deactivation technology consumes the most fuel during frequent stop-and-go in traffic. I tried inflating the tire pressure to 2.6, which is 0.1 higher than the factory standard, and surprisingly reduced highway fuel consumption by 0.3L. Fueling habits are crucial now; using standard fuel from reputable stations can save half a liter per 100km compared to small gas stations. If you drive 2,000km monthly, developing the habit of anticipating road conditions and braking less can save you 2,000 yuan in fuel costs annually.

I've been paying attention to the XT4's fuel consumption data for quite some time. The official combined figure is 8L, but real-world feedback from owner groups generally falls in the 9-10L range. The 2.0T engine has a decent displacement, and 237 horsepower pulling a 1.6-ton body is actually quite reasonable. Compared to the XT5 on the same platform, it's even more fuel-efficient, thanks to the lightweight body and the optimized gear ratios of the 9AT transmission. The other day, I watched an engineer's teardown video, and that variable valve lift system really does shut down two cylinders at a steady 70 km/h. If a hybrid version were to be released, it could probably bring it down to 6L. For now, this fuel consumption level is normal for a luxury brand.

Last week, I just completed a long-distance trip in the XT4 with a full tank showing a range of 720 km. On the highway, cruising at a constant speed of 110 km/h, the fuel consumption stabilized at 7.2L. However, city commuting consumes much more fuel, often reaching 11L during peak hours when shuttling kids to and from school. Friends considering the four-wheel-drive version should note that the multi-plate clutch increases transmission losses, with actual tests showing 0.8L more fuel consumption per 100 km compared to the front-wheel-drive version. The 66-liter fuel tank is quite spacious; each time the fuel light comes on, refueling takes about 55 liters, which lasts me for ten days of commuting.

Researching the cylinder deactivation technology in the XT4 is quite fascinating. When it switches from four cylinders to two, fuel consumption drops significantly. However, frequent start-stop in city driving is particularly fuel-intensive, so I recommend friends driving this car to turn off the auto start-stop function. Running the AC in summer has a noticeable impact on fuel economy, with actual tests showing an increase of 1.2L/100km. Keeping the spare tire compartment free of clutter is crucial—after clearing out the trunk, my fuel consumption dropped by 0.4L. Also, avoid filling the tank completely; filling it to three-quarters is the most economical.

Just helped my cousin pick up a used XT4 and specifically tested three driving conditions: 10.8L/100km fuel consumption during evening rush hour traffic, 8.3L on smooth suburban roads, and achieved an impressive 6.9L at a constant 100km/h on the highway. Discovered that misaligned front wheel positioning data unnecessarily increases fuel consumption - after the last wheel alignment, it saved 0.7L per 100km. Using 5W30 engine oil instead of 40 viscosity saves more fuel, and monthly air filter cleaning improves intake efficiency. The Sport mode makes the throttle overly sensitive in this car, while Standard mode proves most fuel-efficient for city driving.
