The 2020 Audi A5 Sportback quattro gets 27 MPG combined, which isn’t going to win any hypermiling contests, but that number is precisely the point. This isn’t a vehicle bought for ultimate frugality; it’s for buyers who prioritize style, driving experience, and a touch of practicality in a compact package, and who accept the fuel cost that comes with those attributes.

City and highway performance

The EPA estimates the A5 Sportback quattro at 24 MPG in the city and 32 MPG on the highway. The city figure reflects brisk acceleration from stoplights and the demands of navigating urban traffic, situations where the quattro all-wheel-drive system and seven-speed automatic transmission are frequently engaged. The 32 MPG highway number better reflects relaxed cruising, where the engine operates more efficiently and aerodynamic factors become important. However, pushing the A5 Sportback on the highway, as its drivers are often inclined to do, will drop that figure quickly.

Annual fuel cost

Based on EPA estimates of 15,000 miles driven annually and national average fuel prices, the 2020 Audi A5 Sportback quattro 2.0L is projected to cost $2,150 per year in fuel. This figure provides a standardized benchmark for comparing running costs against other vehicles. It assumes a relatively balanced mix of city and highway driving. Drivers who primarily operate in urban environments, or those with a heavy foot, should expect to exceed this amount. Understanding how this figure is calculated allows drivers to adjust the estimate based on their specific driving habits and local fuel prices.

Real-world expectations

The EPA provides a useful standardized estimate, but real-world fuel economy often varies. Factors such as driving style, traffic conditions, weather, and even tire pressure can all impact the numbers you’ll see on your own A5 Sportback’s trip computer. Owners who prioritize smooth acceleration, anticipate traffic flow, and maintain proper tire inflation often report figures closer to or even slightly exceeding the EPA estimates.

Aggressive driving, frequent short trips in cold weather, or neglecting maintenance can easily reduce fuel efficiency significantly. The quattro system, while beneficial for traction and handling in all weather conditions, does add a slight penalty to fuel consumption compared to front-wheel-drive models.

How it compares

The A5 Sportback quattro exists in a competitive segment. The BMW 430i xDrive Gran Coupe, a direct rival, lands around a similar 27 MPG combined. Another consideration might be the Acura TLX SH-AWD, which delivers a slightly lower 24 MPG combined with its more powerful V6 engine. For those prioritizing efficiency above all else, the Lexus IS 300h delivers around 44 MPG combined, but it does comes with a different driving experience and less practicality in terms of cargo space. The choice often comes down to a balance between fuel economy, performance, and the overall driving experience. Comparing these models alongside all Audi fuel economy data and A5 MPG across all years can provide valuable perspective.

Tips to maximize efficiency

Use the Drive Select modes. The “Efficiency” setting optimizes the engine and transmission for fuel conservation, softening throttle response and shifting earlier. Understanding how this mode adapts the car’s behavior can lead to noticeable improvements over time, especially during routine commutes.

Monitor your tire pressure consistently. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Adhering to the recommended tire pressure, typically found on a sticker inside the driver’s side doorjamb, will not only improve fuel economy but also extend tire life and enhance handling.

Minimize unnecessary weight. Removing excess cargo from the trunk and rear seats reduces the overall load the engine has to propel. While this effect isn’t dramatic on a per-trip basis, it can add up to a measurable difference over the long run.

Use cruise control judiciously on the highway, but with awareness. Cruise control maintains a consistent speed, but it may sometimes downshift aggressively on inclines, negating its intended efficiency benefits. Observe how the transmission behaves and manually adjust speed if necessary to maintain momentum without excessive downshifting. Smart cruise control with predictive efficiency assist can further optimize your driving efficiency.
