The 2015 Audi A5 quattro, with its 2.0L turbocharged engine and 6-speed manual transmission, achieves 26 MPG combined. This isn’t hybrid-level fuel economy, but it’s a good compromise for drivers who value performance and an engaging driving experience in a stylish coupe or convertible. Many seeking a sporty, all-weather car with an appealing design find this acceptable, trading some efficiency for a well-tuned chassis and a satisfying manual gearbox.

City and highway performance

EPA estimates for the 2015 A5 quattro manual are 22 MPG in the city and 32 MPG on the highway. The city figure reflects stop-and-go driving, which can challenge any turbocharged engine, and the tendency to use the available power for quick acceleration. The highway number demonstrates the efficiency possible at steady speeds. Achieving 32 MPG depends on the engine operating efficiently and the vehicle’s aerodynamic design. Smart gearing helps keep the engine speed down on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for this A5 configuration at $2,250. This is based on driving 15,000 miles per year with a mix of city and highway driving, and using the national average fuel price at the time. Individual driving habits and fuel price changes can affect the actual cost, but this provides a standard for comparison. While this might seem high to some, owners often accept it for the overall experience.

Real-world expectations

EPA estimates are standardized, but actual fuel economy varies. Drivers who frequently drive aggressively, take short trips, or live in areas with heavy traffic might see numbers closer to the city estimate. On the other hand, those who spend more time on the highway, use a lighter touch on the gas pedal, and maintain their vehicle well may exceed the EPA’s highway rating. The 2.0T engine responds well to driving style; smooth and consistent driving helps achieve better MPG.

How it compares

The 2015 Audi A5 quattro manual compares well to other sporty vehicles of its time. A BMW 428i Coupe with a manual transmission, for instance, offered very similar fuel economy. A Mercedes-Benz C300 Coupe, typically equipped with an automatic transmission, showed comparable figures. A V6-powered Infiniti Q60 consumed more fuel, averaging around 22 MPG combined. These comparisons are important to buyers cross-shopping vehicles with similar performance and luxury. Those exploring the Audi lineup can find all Audi fuel economy data useful.

Tips to maximize efficiency

Proper tire inflation is critical for fuel economy. Underinflated tires increase rolling resistance, making the engine work harder. Check pressure regularly and inflate tires to the pressure on the door jamb sticker.

Avoid aggressive acceleration and hard braking. The turbocharged engine provides plenty of power, but using it excessively uses more fuel. Anticipate traffic and maintain a consistent speed. The manual transmission allows greater fuel economy control.

Minimize idling. If you’ll be stopped for more than a minute or two, turn off the engine. Modern engines restart quickly and efficiently, and idling wastes fuel. This is helpful in city driving.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the recommended schedule, including oil changes, air filter replacements, and spark plug inspections. Dirty oil and clogged air filters can hurt performance and reduce fuel economy.
