Which has higher fuel consumption, the Audi Q5L or the Audi A6L?

[VonClayton]

The Audi Q5L has a fuel consumption of 10.4L/100km, which is higher than the Audi A6L's 9.6L. Introduction to the Audi Q5L: The all-new Audi Q5L is the world's first long-wheelbase premium midsize SUV, with a wheelbase extended by 101mm compared to the previous generation Audi Q5 and 88mm longer than the overseas standard-wheelbase version, reaching a body length of 4,765mm. The Audi Q5L retains the overseas version's 2.0T gasoline engine, with a maximum output of 252 horsepower, mated to a 7-speed dual-clutch transmission, and comes standard with the quattro all-wheel-drive system. Introduction to the Audi A6L: The Audi A6L is a vehicle series developed by FAW-Volkswagen Audi based on the new German A6, serving as the successor to the A6.

I usually drive an Audi Q5L and A6L. During daily commutes, the Q5L has noticeably higher fuel consumption. As an SUV, it's heavier with a higher drag coefficient, consuming more fuel during stop-and-go traffic at traffic lights, averaging 9 to 10 liters per 100 km in urban conditions. In contrast, the A6L, being a sedan, has a lighter and more aerodynamic body, consuming only 7 to 8 liters in city driving. The difference is slightly smaller on long-distance trips, but overall, the Q5L is more fuel-intensive. If you frequently drive in congested urban areas, choosing the A6L can save a significant amount on fuel costs. I've also noticed that seasons have a big impact—using the heater in winter or air conditioning in summer further increases the Q5L's fuel consumption. In summary, based on my experience, SUVs are at a disadvantage in this aspect, especially for commuters who need to consider daily expenses. While the Q5L offers better visibility, you'll need to be prepared to spend more on fuel.

As someone who frequently helps family members choose cars, I've compared the fuel consumption between the Audi Q5L and A6L, and the Q5L is noticeably higher. With its heavier front end and thicker tires, the SUV faces greater wind resistance on highways, averaging 8 to 9 liters per 100 km as the norm. The A6L, being lower with less wind resistance, typically stays around 7 liters on highways. The difference is even more pronounced in city driving—the Q5L often exceeds 10 liters, while the A6L stays under 8 liters. Over the long term, if you drive 10,000 km annually, the Q5L will cost you several hundred yuan more in fuel. From an economic standpoint, the A6L is a more cost-effective choice for daily commuting. Driving habits also matter—my son's aggressive acceleration pushes the Q5L's fuel consumption even higher. If you frequently carry heavy loads or drive on rough roads, the SUV's fuel consumption will worsen, but for regular commuting, sedans are more fuel-efficient. Don’t just focus on cabin space when choosing a car; the fuel consumption gap shouldn’t be overlooked.

I'm familiar with Audi's technical designs. Why does the Q5L consume more fuel than the A6L? The main reasons lie in vehicle weight and aerodynamic drag. The Q5L is an SUV, weighing close to 2 tons with a drag coefficient of approximately 0.34. With the same engine output power, its driving efficiency is lower. In contrast, the A6L is over 0.1 ton lighter, with a drag coefficient of 0.26, offering better aerodynamics. Engine data shows both models are equipped with a 2.0T engine, but the Q5L averages 9L/100km in urban conditions, while the A6L only consumes 7.5L/100km. In real-world driving, the SUV's suspension height also affects fuel consumption. On long-distance drives, the A6L maintains steady engine RPMs, delivering better fuel efficiency. Ultimately, the Q5L's higher fuel consumption is due to its physical characteristics. Regular maintenance should include checking tire pressure, as underinflation can increase fuel consumption. When choosing a model, consider your usage—sportier needs come with this trade-off.
