Q5's actual fuel consumption ranges from 10-14 liters per 100 kilometers, with specific figures varying based on driving habits, weather conditions, and road situations. Detailed information is as follows: Fuel consumption under different road conditions: In urban areas, the Audi Q5 typically consumes around 10-12 liters per 100 km. In cities with severe traffic congestion and air conditioning usage, this can increase to 20-25 liters or more, while the average urban consumption is 11-14 liters. On highways, fuel consumption drops to 8-9 liters. Therefore, the combined average is 11-13 liters, which is quite good for an SUV weighing 1.9 tons. However, since numerous factors affect fuel consumption, the 10-14 liter range should be considered as a reference value rather than an absolute figure.

Last year, driving the older Q5L 40TFSI on long-distance trips, the dashboard showed a combined fuel consumption of 8.3L. However, it's a different story in the city—during morning and evening rush hours with heavy traffic, it often jumps above 13L. I recommend installing a fuel consumption app to track it. I tested the data over three months: gentle driving can keep it around 10L, but if you're impatient and floor the accelerator, you can literally see the fuel gauge drop. Pay special attention to the break-in period and winter, as fuel consumption tends to be higher. Additionally, the quattro system consumes about 0.8L more than the front-wheel-drive version. The 2023 new model with mild hybrid is said to save around 1L, but actual road conditions will determine the real savings.

I've been driving my 45TFSI Sport edition for two and a half years, and have already filled two fuel record notebooks. With AC on in pure city driving (Beijing's Third Ring Road during rush hours), it averages about 13-14L/100km. On highways, it's very fuel-efficient at a stable 7.6L. Last month I specifically tested: a full tank could cover 850km at longest on highways, but only 500+km for city commutes. After upgrading to larger rims, fuel consumption increased by 0.5L. Surprisingly, using 98-octane gasoline gives me 30km more range than 95-octane. After , switching to full synthetic engine oil reduces consumption by about 0.3L.

To focus on fuel consumption, you need to understand the nuances in the official data. The 40TFSI front-wheel-drive model's official rating of 7.7L is an ideal value; in actual city driving, it starts from at least 11L. The new plug-in hybrid version has a pure electric range of 61km, making it almost oil-free for short trips. The older 3rd-gen EA888 engine paired with an 8AT transmission is most fuel-efficient at a steady 90 km/h, as wind resistance increases significantly beyond 120 km/h. Maintaining tire pressure at 2.5bar saves fuel, and keeping the trunk free of unnecessary items also helps. Upgrading to off-road tires increases fuel consumption by 15%, as tested, and snow mode is a real gas guzzler.

Last week, I accompanied a friend to test drive the new Q5. The salesperson said the 40 version has a combined fuel consumption of 8L, but in the old owners' group, everyone is complaining that the actual consumption is around 10L. Actually, it depends on personal driving habits: anticipating traffic lights and braking less can save a lot, while the start-stop function is rather useless. In northern winters, warming up the car for five minutes can make the displayed fuel consumption soar to a scary 20L. It's recommended to regularly clean the throttle body, as cars with severe carbon buildup can consume 3L more. I've observed the onboard computer, and using the air conditioning compressor consumes more fuel than the heater.

A veteran who has driven three generations of Q5 reminds: don't just look at the fuel consumption numbers. The third-generation EA888 engine was modified three times. The 2017 model burned oil and was particularly fuel-thirsty, and after the 2020 model solved that issue, it encountered problems with particulate filter clogging. For urban commuting, the 40TFSI is sufficient, while the 45 performance version increases fuel consumption by 30%. The transmission is crucial: the old 8AT was jerky at low speeds and consumed more fuel, while the new dual-clutch has significantly improved. During highway cruising at 100 km/h, the instantaneous fuel consumption can reach 5.9L, but it jumps to 8L once exceeding 130 km/h. Don't overfill the engine oil—exceeding the upper limit increases resistance and fuel consumption.
