The 2019 Audi A3 Cabriolet quattro 2.0L achieves a combined EPA-estimated 25 MPG. This is acceptable, but not outstanding, for a small, turbocharged luxury convertible with all-wheel drive. Consider this number in light of what the car is: a stylish and sporty open-top experience. It is aimed at buyers who prioritize panache and year-round usability over saving on gas. They understand that fuel consumption is the price you pay for a premium driving experience with the security of quattro all-wheel drive.

City and highway performance

The EPA breaks down the A3 Cabriolet’s fuel economy, estimating 22 MPG in the city and 30 MPG on the highway. The city figure reflects urban driving with its stop-and-go conditions, where the engine works harder and uses more fuel while idling. The highway number is more promising. It shows the efficiency the A3 can achieve when cruising at a steady speed. The seven-speed automatic transmission (AM-S7) is important here. It optimizes revs for efficiency and performance, depending on driving conditions. Drivers who commute in congested areas should expect consumption closer to the city estimate. Those who spend more time on open roads will likely see figures closer to the highway rating, or even slightly exceeding it.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Audi A3 Cabriolet quattro 2.0L to be $1,750. This is based on driving 15,000 miles per year and using national average fuel prices. This is an estimate. Individual fuel costs will vary depending on driving habits, local fuel prices, and the grade of fuel used. However, the figure provides a useful benchmark. It helps prospective buyers factor fuel expenses into the overall cost of ownership.

Real-world expectations

While the EPA provides a standardized measure, real-world fuel economy can vary. Aggressive driving, frequent short trips, and carrying extra weight can all negatively impact fuel consumption. Smooth acceleration, consistent speeds, and proper tire inflation can help drivers achieve figures closer to the EPA estimates.

The A3 Cabriolet’s all-wheel-drive system provides enhanced traction and stability, but it also adds weight and drivetrain friction. This can reduce fuel efficiency compared to a front-wheel-drive variant. Given that A3 Cabriolet buyers typically enjoy the car’s performance, expecting figures consistently above the EPA combined rating might be optimistic.

How it compares

Compared to its competitors, the 2019 Audi A3 Cabriolet’s fuel economy is competitive, but not class-leading. For example, the BMW 230i Convertible, with its rear-wheel drive, achieves around 28 MPG combined. The Mercedes-Benz C300 Cabriolet, typically equipped with a slightly larger engine, lands in a similar range as the A3.

The all-wheel-drive configuration of the A3 quattro is a key differentiator, offering superior all-weather capability that the rear-wheel-drive BMW can’t match. Buyers who prioritize all-weather security are generally willing to accept the slight fuel economy penalty. Weigh the benefits of all-wheel drive against the potential fuel savings of a comparable rear-wheel-drive or front-wheel-drive alternative. You can also research A3 MPG across all years to see how the A3 has evolved.

Tips to maximize efficiency

Optimizing tire pressure is a simple way to improve fuel economy. Check your tires regularly and maintain the pressure recommended on the sticker inside the driver’s side doorjamb. Even a few PSI below the recommended level can increase rolling resistance, leading to a noticeable decrease in MPG.

Avoid aggressive acceleration and hard braking. The A3’s turbocharged engine is responsive, but using its full power frequently will lower fuel economy. Smooth and steady driving will keep the engine in its most efficient operating range.

Minimize idling. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, and idling burns fuel without covering any distance.

Consider using the Audi Drive Select system to optimize fuel economy. Many A3 models have this feature, which allows you to choose different driving modes. Selecting “Efficiency” mode will adjust the engine and transmission settings to prioritize fuel savings, often at the expense of quicker acceleration.

Remove unnecessary weight from the car. Extra cargo adds to the vehicle’s overall weight, forcing the engine to work harder and consume more fuel. Clean out your trunk and remove any items you don’t need regularly. This small change can make a noticeable difference, especially during city driving.
