The 2020 Audi SQ8 4.0L 8-cyl gets 17 MPG combined. It’s a machine engineered for strong performance and striking looks, not to compete with a Prius on fuel efficiency. To be clear, someone interested in the SQ8 probably cares more about power than saving fuel. They want the sound of a potent twin-turbo V8 go with their fast driving, all in a head-turning design.

City and highway performance

The SQ8’s EPA estimates are 15 MPG in the city and 21 MPG on the highway. The city number, which seems low, shows how much gas a powerful engine uses in stop-and-go traffic. The temptation to use all 500 horsepower is always there, and quick bursts of acceleration burn a lot of fuel. The 21 MPG highway rating is better, which means you can save some fuel when cruising steadily. The eight-speed automatic transmission helps keep the engine running efficiently when you are not pushing it hard.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Audi SQ8 at $3,400. This is based on driving 15,000 miles per year and using average national fuel prices. Premium fuel is required for best performance and to keep the engine running well. Fluctuations in fuel prices change this annual cost, and could make it higher.

Real-world expectations

Fuel economy depends on how and where you drive. The EPA figures are a starting point, but driving fast, taking many short trips, or driving in heavy traffic will probably lower your MPG. On the other hand, someone who drives more carefully, mainly on open highways, could see slightly better numbers. Still, expecting to consistently beat the EPA estimates in an SQ8 is optimistic because its design encourages spirited driving, and it is hard to resist the temptation.

How it compares

The SQ8’s fuel economy is similar to its competitors. The BMW X6 M, which also has a high-performance V8, gets almost the same 15 MPG city, 20 MPG highway. The Mercedes-AMG GLE 63 S Coupe, another competitor, gets about the same numbers. These comparisons show that fuel efficiency is less important in this class of vehicle. Owners are okay with using more fuel to get more power and something exclusive. You can find all Audi fuel economy data here and SQ8 MPG across all years.

Tips to maximize efficiency

While the SQ8 is not designed for maximum fuel savings, some habits can help you save gas. Accelerate gently and anticipate traffic to reduce hard braking and acceleration, which minimizes fuel consumption. Using adaptive cruise control on the highway helps keep a steady speed and save fuel on long trips.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure and inflate them to the recommended levels on the tire placard on the driver’s side doorjamb.

Avoid carrying unnecessary weight. The heavier the vehicle, the more fuel it consumes. Remove any items from the trunk or passenger compartment that are not essential. Even small amounts of extra weight can add up and affect fuel economy.

Minimize idling. Letting the engine idle wastes fuel. If you expect to stop for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you don’t need to keep them running.
