22 MPG combined isn’t going to win any hypermiling competitions, but for the 2019 Audi RS 3 and its explosive 2.5L turbocharged five-cylinder, it’s a figure most owners happily accept. This isn’t a car bought for sipping fuel, but for its distinctive engine note, tenacious grip, and surprisingly practical four-door format. RS 3 buyers prioritize performance above all else, and they know this means more trips to the pump than, say, a Prius.

City and highway performance

The EPA estimates the 2019 RS 3 at 19 MPG in the city and 28 MPG on the highway. Those numbers reflect the realities of a high-strung engine designed to deliver maximum power on demand. The city figure suffers from frequent stops, where the turbocharger is constantly spooling and the engine is often operating out of its most efficient rev range. The highway number, while respectable, can easily dip if you’re tempted to exploit the RS 3’s impressive overtaking ability, and who isn’t?

Annual fuel cost

The EPA calculates that the average owner of a 2019 Audi RS 3 will spend $2,650 per year on fuel. This figure is based on driving 15,000 miles annually, a mix of city and highway driving, and assumes national average fuel prices. Of course, these costs can change depending on your driving style, typical routes, and current gasoline costs. The RS 3 also requires premium fuel, which will contribute to higher overall running costs.

Real-world expectations

While EPA estimates provide a useful baseline, real-world fuel economy often changes. RS 3 drivers who like aggressive acceleration and frequent track days will likely see numbers lower than the official figures. Conversely, those who mostly commute on the highway and drive gently might achieve slightly better fuel economy. Don’t be surprised to see averages hovering around 20 MPG in mixed driving. The RS 3’s personality invites spirited driving, impacting fuel consumption. For those seeking to minimize fuel costs, understanding this car’s purpose is important.

How it compares

Compared to other compact performance sedans, the RS 3’s fuel economy is in the middle of the pack. The BMW M2 Competition, with its 405-hp inline-six, achieves a slightly better 20 MPG combined. The Mercedes-AMG CLA 45, with its potent 375-hp four-cylinder, is rated at 23 MPG combined. The Acura Integra Type S with a turbocharged 2.0 liter delivers 24 MPG combined. However, none of these options offer the unique character and soundtrack of the RS 3’s five-cylinder engine. Ultimately, buyers drawn to the RS 3 knowingly trade a few MPGs for the distinct driving experience it provides. More broadly, you can review RS MPG across all years to understand how this model’s fuel economy has evolved.

Tips to maximize efficiency

Use the Audi Drive Select system and choose the “Efficiency” mode for everyday driving. This mode reduces throttle response and optimizes shift points to prioritize fuel conservation. While it won’t transform the RS 3 into an economy car, it can make a noticeable difference when cruising on the highway.

Pay close attention to tire pressure. Maintaining the correct inflation not only improves fuel economy but also enhances handling and extends tire lifespan. Check your tire pressure regularly, especially before longer trips.

Anticipate traffic flow and avoid unnecessary acceleration and braking. Smooth driving conserves fuel. The RS 3’s powerful brakes are great on the track, but gentle deceleration in everyday driving is more efficient.

Resist the urge to constantly exploit the engine’s performance. The RS 3’s turbocharger is fun, but frequent bursts of acceleration significantly decrease fuel economy. Save the full throttle for when you need it. Understanding all Audi fuel economy data can also offer broader context.
