24 MPG combined is the fuel economy for open-air driving with all-weather confidence in the 2017 Audi A5 Cabriolet quattro 2.0L. Owners of this vehicle aren’t primarily focused on efficiency, they want the combination of great styling, turbocharged performance, and the stability that only a German-engineered, all-wheel-drive convertible provides. It’s a reward, not a necessity.

City and highway performance

The EPA estimates of 21 MPG in the city and 29 MPG on the highway realistically reflect the A5 Cabriolet quattro’s behavior. In town, the turbocharged 2.0L engine doesn’t need to work hard, but stop-and-go driving will impact fuel consumption. The S tronic dual-clutch transmission’s responsiveness is a plus, though it won’t deliver hybrid-like savings. The A5 shines on the open road. Cruising at highway speeds, the engine settles into a relaxed rhythm, and the aerodynamics, sleek for a convertible, help achieve respectable fuel economy. You can expect to see numbers close to 29 MPG on longer trips, if you avoid using the available power too much.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2017 Audi A5 Cabriolet quattro 2.0L at $2,400. This is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, and assumes national average fuel prices. Individual fuel costs will vary depending on driving habits, location, and prevailing fuel prices. Owners who spend more time in congested urban environments or drive aggressively will likely exceed this estimate. However, those who primarily drive on highways or are fuel-conscious could potentially spend less.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary considerably. Owners report figures in line with the EPA numbers, but aggressive driving and frequent use of the sport mode will lower the average. Factors like ambient temperature, tire pressure, and using accessories like air conditioning can also affect fuel consumption. Expect a range of 22-27 MPG in mixed driving conditions, but figures outside this range are possible depending on how it’s used.

How it compares

The 2017 A5 Cabriolet’s fuel economy is comparable to its closest competitors. The BMW 430i Convertible, for example, achieves an EPA-estimated 28 MPG combined with rear-wheel drive. The Mercedes-Benz C300 Cabriolet with rear-wheel drive also lands around 25 MPG combined. The Audi’s slightly lower MPG figure comes with quattro all-wheel drive, a key difference for buyers who want year-round usability. If fuel economy is a primary concern, there are other convertible options in different segments that offer better numbers, but they lack the A5’s premium feel and sporty character.

Tips to maximize efficiency

The turbocharged 2.0L engine responds well to a light foot. Avoid aggressive acceleration and braking, especially in city driving. Anticipate traffic flow and maintain a steady speed when possible. The A5’s engine management system is designed to optimize fuel efficiency, but it can only do so if you drive smoothly.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder, consuming more fuel as a result. Check your tire pressure regularly and maintain the recommended levels specified in the owner’s manual or on the driver’s side doorjamb. A simple tire pressure gauge can make a big difference.

Minimize unnecessary weight. Carrying extra cargo in the trunk or storing items on the rear seats increases the vehicle’s overall weight and reduces fuel efficiency. Remove items you don’t need to carry regularly, especially heavy objects. Even small changes can add up.

Consider using the Economy driving mode (if equipped). Many Audis feature selectable driving modes that allow you to prioritize fuel efficiency. The Economy mode typically adjusts the throttle response and transmission shift points to optimize fuel consumption. It might not be as exciting as the Sport mode, but it can make a noticeable difference on long drives.

Schedule regular maintenance. A well-maintained engine is a fuel-efficient engine. Follow the recommended maintenance schedule in your owner’s manual, including regular oil changes, air filter replacements, and spark plug inspections. Addressing minor issues promptly can prevent them from escalating into more serious problems that can negatively impact fuel economy.
