The 2018 Audi A5 Sportback quattro with the 2.0L 4-cylinder engine gets 27 MPG combined. While that won’t win any hypermiling awards, it’s a respectable figure for a car that blends coupe-like styling with the practicality of a hatchback and the confidence of all-wheel drive. This isn’t a vehicle bought solely for saving money on gas. It’s a style statement, a functional choice, and a performance-oriented machine engineered for drivers who appreciate both form and function. The A5 Sportback owner prioritizes a blend of aesthetics, usability, and sure-footed handling over outright fuel efficiency.

City and highway performance

The EPA estimates the 2018 A5 Sportback quattro achieves 24 MPG in the city and 34 MPG on the highway. The city number reflects the demands of stop-and-go traffic, where the engine works harder and the all-wheel-drive system can contribute to increased consumption. The highway figure highlights the A5 Sportback’s comfortable cruising ability, with its efficient 2.0L engine settling into a relaxed rhythm. The 7-speed dual-clutch automatic transmission (AM-S7), known for its quick and smooth shifts, plays a crucial role in optimizing fuel economy at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Audi A5 Sportback quattro to be $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits, local fuel prices, and the proportion of city versus highway driving. While fuel prices fluctuate constantly, the $2,150 benchmark provides a reasonable estimate for budgeting purposes.

Real-world expectations

Real-world MPG often differs considerably from EPA estimates. Drivers who frequently accelerate quickly, navigate congested traffic, or live in hilly areas might see lower numbers than the official ratings. However, those who drive smoothly and spend more time on open highways might achieve figures closer to, or even slightly exceeding, the EPA’s 34 MPG highway estimate. Remember that quattro all-wheel-drive always adds a small fuel consumption penalty because of the extra weight and mechanical drag.

How it compares

Considering the A5 Sportback’s style, utility, and all-wheel drive, its fuel economy compares well to competitors. The BMW 430i xDrive Gran Coupe, a direct rival, achieves a similar 27 MPG combined. However, the Mercedes-Benz C300 4MATIC Sedan offers a comparable luxury experience, but posts a slightly lower 25 MPG combined. The Acura TLX SH-AWD, with its V6 engine, comes in at 24 MPG combined. These differences, while seemingly minor, can add up over the course of a year. Drivers seeking better fuel efficiency might consider the front-wheel-drive A5 Sportback, which does without the quattro all-wheel-drive system for better MPG. Compare all Audi fuel economy data to better understand where the A5 Sportback places within the broader Audi lineup.

Tips to maximize efficiency

Gentle acceleration and smooth braking are key to maximizing fuel economy in the A5 Sportback. The 2.0L turbocharged engine delivers ample power, so avoid excessive throttle application, especially when accelerating from a standstill. Anticipate traffic flow and maintain a consistent speed whenever possible to minimize unnecessary braking and acceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which significantly reduces fuel economy and can also lead to premature tire wear. Check your tire pressures regularly, ideally weekly, and inflate them to the recommended levels listed on the doorjamb sticker.

Reduce unnecessary weight. Carrying extra items in the trunk or backseat adds to the vehicle’s overall weight, forcing the engine to work harder and consuming more fuel. Remove any items you don’t need regularly, such as sports equipment or tools.

Take advantage of the A5 Sportback’s drive select modes. Experiment with the “Efficiency” mode, if equipped. This mode optimizes various vehicle parameters to improve fuel economy and might adjust throttle response, shift points, and even climate control settings to prioritize efficiency.

Maintain your vehicle according to the recommended service schedule. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs efficiently and reliably. A poorly maintained engine can experience reduced fuel economy and increased emissions.
