The 2022 Audi A5 Cabriolet quattro, with its 2.0L 4-cylinder engine, achieves 26 MPG combined. Nobody buys a stylish, open-top convertible with all-wheel drive primarily for fuel efficiency. They buy it for the experience: the wind in their hair, the sleek design, and the confidence of quattro all-wheel drive. In this context, 26 MPG is an acceptable compromise for the style and driving enjoyment the A5 Cabriolet delivers.

City and highway performance

The EPA estimates the A5 Cabriolet at 23 MPG in the city and 31 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine spends more time idling or accelerating from a standstill. The highway number shows the engine’s efficiency when cruising at a steady speed. These figures are largely attributable to the 7-speed S tronic dual-clutch transmission. It offers quick shifts and helps keep the engine in its most efficient rev range, especially on the open road.

Annual fuel cost

The EPA calculates that the average driver of the 2022 Audi A5 Cabriolet will spend $2,250 per year on fuel. This figure assumes 15,000 miles of driving annually, with a specific proportion of city versus highway miles, using the national average fuel price. Note that your actual fuel costs will vary depending on your driving habits, the type of roads you frequent, and local fuel prices. Aggressive driving will lower your MPG and increase your fuel bill, while conservative driving will improve your fuel economy.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy can vary. Drivers who frequently engage the “sport” mode or drive aggressively can expect to see mileage closer to the 23 MPG city estimate, or even lower. However, drivers with a light foot who prioritize fuel efficiency on longer trips can potentially exceed the 31 MPG highway estimate. The A5 Cabriolet’s quattro all-wheel-drive system provides enhanced traction and stability, adding weight and contributing to a slight decrease in fuel economy compared to front-wheel-drive competitors.

How it compares

The A5 Cabriolet sits in a niche market, with few direct convertible competitors offering all-wheel drive. The BMW 430i Convertible, a rear-wheel-drive alternative, achieves 28 MPG combined, offering a slight edge in fuel economy. However, it lacks the all-weather capability of the quattro system. Looking at other Audi models, you can compare the A5 Cabriolet to A5 MPG across all years. The Audi A4 sedan with quattro and the same 2.0T engine nets a combined of 28 MPG, though it is not a convertible. The Mercedes-Benz C300 Cabriolet, also rear-wheel drive in its base form, posts a similar 25 MPG combined. The A5 Cabriolet’s fuel economy is competitive within its class, considering its standard all-wheel drive.

Tips to maximize efficiency

Consider using Audi’s Drive Select system to prioritize efficiency. Selecting the “Efficiency” drive mode can alter the engine mapping, transmission behavior, and even climate control settings to maximize fuel economy. It might slightly diminish the car’s sporty character, but it can make a noticeable difference on longer trips. Familiarize yourself with all Audi fuel economy data to improve your knowledge.

Minimize unnecessary weight in the vehicle. Extra cargo in the trunk adds weight, forcing the engine to work harder and consume more fuel. Regularly remove any items you don’t need to carry, optimizing the car’s weight-to-power ratio. Also be extra careful with larger fuel-economy obstacles such as roof racks, which will only reduce speed and efficiency.

Proper tire inflation is important. Check your tires regularly and inflate them to the recommended pressure listed on the doorjamb. Underinflated tires increase rolling resistance, which hurts fuel economy, and results in accelerated wear. A simple tire pressure monitoring system (TPMS) is convenient but does not replace the need to check pressure manually.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth, deliberate driving enhances the driving experience and significantly improves fuel economy. Maintaining a consistent speed and avoiding sudden stops or starts allows the engine to operate more efficiently.
