22 MPG combined is what prospective 2016 Audi A8 L 4.0T buyers should expect. It’s not terrible, but performance is usually why someone chooses a long-wheelbase A8 with a twin-turbo V8. This car signals success and a desire for a refined driving experience. Fuel economy is a secondary, but still relevant, concern.

City and highway performance

The EPA estimates the 2016 Audi A8 L 4.0T gets 18 MPG in the city and 29 MPG on the highway. The city figure shows the demands of stop-and-go traffic, and the engine’s need to work harder to overcome the car’s weight. The highway number is more attractive, showing the engine’s efficiency at cruising speeds, aided by the smooth eight-speed automatic transmission that allows the engine to run at lower RPMs. This difference shows that driving style and conditions significantly impact the A8 L’s real-world fuel consumption. The turbochargers add fun, but that fun comes straight from the gas tank.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Audi A8 L 4.0T at $2,650. This is based on driving 15,000 miles per year, split evenly between city and highway driving, and using the EPA’s estimate of national average fuel prices. Fluctuating fuel prices and individual driving habits can change this number. If you primarily drive in the city, your annual fuel cost will likely exceed $2,650. On the other hand, mostly highway driving could lower it. Premium fuel is recommended, which impacts the overall cost.

Real-world expectations

The EPA provides a standardized estimate, but real-world MPG for the 2016 Audi A8 L 4.0T will vary depending on driving style, traffic conditions, and maintenance. Aggressive acceleration, frequent hard braking, and neglecting scheduled maintenance will all negatively affect fuel economy. A smooth driving style, anticipating traffic flow, and keeping the car properly maintained will help you achieve closer to the EPA estimates.

Expect to see numbers ranging from the mid-teens in heavy city traffic to low 30s on long highway journeys. Those considering an A8 L need to understand that the V8 engine likes to be driven hard, and that comes at a price.

How it compares

The 2016 Audi A8 L 4.0T’s fuel economy is competitive compared to its rivals, but not class-leading. The BMW 750Li xDrive, with its similar twin-turbo V8, achieves roughly the same 22 MPG combined. The Mercedes-Benz S550 4MATIC, another direct competitor, is around a similar figure as well. However, a six-cylinder version of these luxury sedans, like Audi’s own A8 L 3.0T, boosts fuel economy considerably, achieving closer to 25 MPG combined. This is a worthwhile compromise for some.

Examining A8 MPG across all years shows how Audi has worked on this over time. Buyers should weigh the performance benefits of the V8 against the slightly higher fuel costs when deciding. Consider all Audi fuel economy data to find the right fit.

Tips to maximize efficiency

One crucial factor is tire pressure. Ensure your tires are inflated to the recommended pressure, found on the doorjamb sticker. Underinflated tires create more rolling resistance, forcing the engine to work harder and decreasing fuel efficiency. Regularly checking and maintaining proper tire pressure is a simple way to improve MPG without sacrificing performance.

Anticipate traffic flow and avoid aggressive driving habits. Sudden acceleration and hard braking waste fuel. Maintain a smooth and consistent speed, anticipating traffic signals and slowing down gradually. This improves fuel economy and enhances the driving experience.

The A8’s selectable drive modes (Comfort, Auto, Dynamic) can influence fuel consumption. Dynamic mode unleashes the V8’s full potential, but it also consumes more fuel. Use Comfort or Auto mode for everyday driving instead. These modes prioritize fuel efficiency by adjusting the engine and transmission settings.

Reduce unnecessary weight in the car by removing any items from the trunk or backseat that aren’t essential. Extra weight forces the engine to work harder, reducing fuel economy. A lighter vehicle is a more efficient vehicle.

Finally, adhere to the recommended maintenance schedule. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs efficiently. A well-maintained engine delivers optimal performance and fuel economy.
