The 2021 Audi A5 Sportback quattro with the 2.0L 4-cylinder engine achieves 28 MPG combined, which is a respectable figure. This fuel economy reflects the car’s blend of style, practicality, and performance with reasonable fuel efficiency. This isn’t a hybrid or an economy car. It’s a sleek, all-wheel-drive hatchback designed for drivers who appreciate driving dynamics and a premium experience, and who also need everyday usability. The A5 Sportback owner likely prioritizes design and driving enjoyment over outright fuel savings, so the 28 MPG is a welcome bonus rather than the primary deciding factor.

City and highway performance

The EPA estimates for the 2021 Audi A5 Sportback quattro are 25 MPG in the city and 34 MPG on the highway. The city MPG is adequate, reflecting stop-and-go traffic with a turbocharged engine and all-wheel drive. The A5 Sportback excels on the highway. Its relatively aerodynamic shape and well-calibrated 7-speed automatic transmission (AM-S7) allow it to cruise efficiently at higher speeds. Long road trips are easily within this car’s comfort zone, both for the driver and the fuel budget. The transmission’s higher gears help to lower fuel consumption on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Audi A5 Sportback quattro at $2,050. This figure is based on driving 15,000 miles per year, with a roughly 55/45 split between city and highway driving, using the national average fuel price at the time of calculation. Individual fuel costs will vary depending on driving habits and local fuel prices. Those who do more city driving or live in areas with higher fuel costs will likely see a higher annual expenditure. The $2,050 figure offers a useful benchmark for understanding the A5 Sportback’s running expenses.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy can vary. Expect to see numbers slightly below the EPA figures if your daily commute involves heavy traffic congestion or many short trips in cold weather. Consistent highway driving at moderate speeds could yield fuel economy exceeding the 34 MPG estimate. Aggressive driving habits, frequent use of “Sport” mode, and carrying heavy loads will negatively impact fuel consumption. Drivers realistically achieve the EPA combined figure with mindful driving.

How it compares

The 2021 Audi A5 Sportback quattro is competitive within the luxury compact segment. The BMW 430i xDrive Gran Coupe, another stylish hatchback with all-wheel drive, offers similar fuel economy around 24 MPG city and 33 MPG highway. The Mercedes-Benz C300 4MATIC sedan, while not a hatchback, posts figures around 23 MPG city and 33 MPG highway. The Acura TLX SH-AWD, known more for its performance, manages about 21 MPG city and 31 MPG highway. Compared to other similar performance vehicles, the A5 Sportback offers good fuel economy.

Tips to maximize efficiency

Optimize your tire pressure. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on the sticker located on the driver’s side doorjamb. Underinflated tires increase rolling resistance, impacting fuel economy.

Anticipate traffic flow. Maintaining a steady speed and avoiding hard acceleration and braking can improve fuel efficiency. Look ahead and anticipate changes in traffic flow to minimize unnecessary speed adjustments.

Use “Efficiency” or “Comfort” driving modes. These modes optimize the engine and transmission settings for less gas. Sport mode may provide quicker acceleration, but it consumes more fuel. For everyday driving, the calmer modes work best to improve your A5 MPG across all years. See A5 MPG across all years.

Reduce excess weight. Carrying unnecessary items in your vehicle adds weight and increases fuel consumption. Remove any items from your trunk or backseat that you don’t need regularly, such as sporting equipment or tools.

Avoid prolonged idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to be restarted without significant wear and tear, and idling consumes fuel without moving the vehicle.
