The 2022 Audi RS 5 Sportback delivers 21 MPG combined, a figure that won’t win any awards but also doesn’t deter its core buyer. This is an RS model, a designation that prioritizes performance above all else. Fuel economy is acknowledged, but it’s far down the list of priorities for someone signing on the dotted line for a car that can accelerate to 60 mph in under four seconds.

City and highway performance

The EPA estimates the RS 5 Sportback achieves 18 MPG in the city and 25 MPG on the highway. These numbers reflect the realities of stop-and-go traffic versus sustained cruising speeds. The city figure suffers because the engine is thirsty under acceleration and the frequent need to tap into its power reserves. The highway number is better, but still limited by the car’s performance gearing and the fact that even at cruising speed, the turbocharged V6 is ready to deliver instant power for overtaking.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Audi RS 5 Sportback at $2,750. This is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which this engine requires. This figure provides a benchmark for understanding the long-term running costs associated with owning a high-performance vehicle. While the initial purchase price is significant, the ongoing fuel expenses add up, so it’s important to factor them in. See all Audi fuel economy data here.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Aggressive driving habits, traffic conditions, and even the terrain can all impact the numbers you see on the fuel economy display. Owners who frequently exploit the RS 5’s performance potential will likely see figures below the EPA estimates. Those who prioritize smooth acceleration and anticipate traffic flow might achieve numbers closer to, or even slightly above, the EPA’s estimates. Ultimately, your driving style dictates your fuel bill. Check out RS MPG across all years models here.

How it compares

The RS 5 Sportback’s fuel economy lags behind some of its competitors, but it’s also important to consider the trade-offs. The BMW M3 Competition Sedan offers comparable performance, but achieves roughly 16 MPG in the city and 23 MPG on the highway, potentially leading to higher real-world fuel costs. The Mercedes-AMG C43 Sedan, with its less powerful engine, fares slightly better, averaging around 19 MPG combined. The Porsche Panamera 4S, a larger and more luxurious vehicle, lands in the same ballpark with around 18 MPG combined. This comparison matters to the RS 5 buyer because it highlights the performance-versus-efficiency equation. Some buyers will happily sacrifice a few MPG for the RS 5’s unique character and driving experience, while others might prioritize slightly better fuel economy from a competitor.

Tips to maximize efficiency

Understanding your driving style is important because a heavy foot can significantly decrease fuel economy. Try to anticipate traffic flow and maintain a steady pace whenever possible. Avoiding sudden acceleration and aggressive braking will help keep the engine operating in its most efficient range.

The RS 5’s driving mode settings can also influence fuel consumption. Selecting the “Comfort” or “Efficiency” mode will prioritize fuel economy by adjusting throttle response and transmission mapping. While these modes may not unleash the car’s full potential, they can make a difference on longer journeys.

Regular maintenance, including timely oil changes and air filter replacements, is critical for maintaining optimal fuel economy. A well-maintained engine operates more efficiently, ensuring that you get the most out of every drop of fuel. Dirty air filters and old oil can hinder performance and reduce gas mileage.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly, especially during temperature changes, as pressure can fluctuate.
