24 MPG combined offers only a glimpse of the 2016 Audi A6 quattro 3.0L’s appeal. It’s not just about squeezing every last mile from a gallon; it’s about balancing performance and efficiency in a well-designed sedan. Owners aren’t solely shopping for low fuel costs. They want reliable all-weather traction, a smooth and powerful six-cylinder engine, and a premium driving experience, all within Audi’s understated elegance. Fuel savings are merely a bonus to this buyer’s priorities.

City and highway performance

The EPA estimates for the 2016 A6 3.0T quattro are 20 MPG in the city and 29 MPG on the highway. That highway figure is achievable on long road trips if speeds are kept reasonable. The city MPG is more dependent on driving style and traffic conditions. Drivers with a heavier foot, or those stuck in stop-and-go traffic, should expect numbers closer to the high teens. The eight-speed automatic transmission is well-tuned for both quick acceleration and relaxed cruising, contributing to efficient power delivery in various driving situations.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Audi A6 quattro 3.0L at $2,400. This is based on driving 15,000 miles per year, with a roughly 55/45 split between city and highway driving at prevailing national average fuel prices for premium gasoline. Remember that as fuel prices change, and as the ratio of city versus highway driving changes, the actual fuel cost will vary. For example, if annual mileage falls below 10,000, the annual fuel expenditure will be lower, and this could be offset by less fuel efficient driving habits.

Real-world expectations

While the EPA provides a standard, real-world MPG often differs. Expect to see figures slightly below the combined 24 MPG in mixed driving, especially if you like to use the supercharged V6’s power. Quick acceleration and frequent short trips will reduce fuel economy.

On the other hand, those who prioritize smooth driving and spend time on the open road should find it relatively easy to match or exceed the EPA highway figure. Tire inflation and vehicle maintenance are also important, neglecting these will harm fuel efficiency.

How it compares

The A6’s fuel economy is competitive, though there are differences. A similarly equipped BMW 535i xDrive from the same year gets roughly the same combined MPG. The Mercedes-Benz E400 4MATIC, another close competitor, posts similar numbers. The Lexus GS 350 AWD, offers similar luxury and performance, and might get slightly better gas mileage on the highway, coming in at 26 MPG Combined and 29 MPG Highway, depending on the model year. The A6’s slight dip in fuel economy compared to some rivals may be worth it for many buyers who want its sharp styling and engaging driving. For all Audi fuel economy data, it is below more fuel-efficient models like the A3 e-tron, but above performance-oriented S and RS models.

Tips to maximize efficiency

Anticipate traffic flow to minimize unnecessary braking and acceleration. The A6’s quattro all-wheel-drive system provides exceptional grip, but fast starts use extra fuel. A smooth and steady approach is more efficient.

Regular maintenance, particularly tire inflation and oil changes, is important. Underinflated tires increase rolling resistance, forcing the engine to work harder. Using the correct grade of synthetic oil and ensuring timely oil changes will help the engine run smoothly.

Use the Audi Drive Select system’s “Efficiency” mode when you can. This setting optimizes engine and transmission settings for maximum fuel economy. It changes throttle response and encourages earlier upshifts, promoting a more fuel-conscious driving style.

Minimize idling. Modern engines consume fuel even when stationary. If you expect a long stop, consider switching off the engine. Restarting is quick and easy, thanks to the A6’s technology.

Reduce aerodynamic drag by removing unnecessary items from the roof rack or trunk. Added weight and wind resistance hurt fuel economy. Keeping the vehicle streamlined will help MPG, especially on highway driving. Consider consulting A6 MPG across all years for more information.
