27 MPG combined is a reasonable compromise for the 2018 Audi A5 quattro 2.0L. Buyers of this car aren’t *solely* focused on maximizing fuel efficiency. They want a stylish coupe or Sportback with a premium interior, engaging handling, and the reassurance of quattro all-wheel drive. Gas mileage is a consideration, of course, but performance and image often take precedence. This A5 strikes a decent balance, offering respectable fuel economy without sacrificing the driving experience Audi owners expect.

City and highway performance

The 2018 Audi A5 quattro achieves an EPA-estimated 24 MPG in the city, where its responsive engine and quick-shifting seven-speed automatic transmission provide ample power for navigating urban traffic. The all-wheel-drive system ensures confident grip in all conditions, adding to the feeling of security during stop-and-go driving.

Out on the open road, the A5 performs well, delivering an impressive 34 MPG on the highway. This makes it a comfortable and efficient long-distance cruiser, capable of covering miles effortlessly while keeping fuel consumption in check. The overdrive ratios in the transmission help maintain low engine speeds at cruising speeds, further contributing to fuel savings.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Audi A5 quattro 2.0L at $2,150. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes the current national average fuel price. Individual spending on fuel will vary depending on driving habits, local fuel prices, and the actual number of miles driven annually. However, $2,150 provides a solid baseline for budgeting fuel expenses for this model.

Real-world expectations

While the EPA estimates offer a useful benchmark, real-world fuel economy can vary significantly. Factors like driving style, weather conditions, and terrain all play a role. Aggressive acceleration, frequent hard braking, and prolonged idling will all negatively impact fuel consumption. Similarly, cold weather can reduce fuel efficiency as the engine takes longer to reach its optimal operating temperature. Hilly or mountainous terrain demands more power from the engine, leading to increased fuel usage. However, drivers who adopt a smooth and consistent driving style, minimize idling, and practice proper vehicle maintenance are more likely to achieve or even exceed the EPA estimates.

How it compares

The 2018 Audi A5 quattro stacks up competitively against other luxury coupes and Sportbacks in its class. The BMW 430i xDrive coupe, similarly equipped with a 2.0L turbocharged engine and all-wheel drive, achieves an EPA-estimated 27 MPG combined, matching the A5. The Mercedes-Benz C300 4MATIC coupe achieves a slightly lower 25 MPG combined. The Lexus RC 300 AWD, with its V6 engine, lags further behind at 22 MPG combined. For A5 buyers, the comparison reveals that opting for the quattro all-wheel-drive system doesn’t come with a significant fuel economy penalty compared to its direct competitors. Buyers can review A5 MPG across all years to determine how this model year stacks up against others.

Tips to maximize efficiency

Pay attention to tire pressure. Maintaining the correct tire pressure, as specified on the door jamb sticker, minimizes rolling resistance and improves fuel economy. Underinflated tires create more friction, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, especially with changes in temperature.

Use the Audi Drive Select system wisely. The A5 offers selectable driving modes, including an “Efficiency” mode that optimizes various vehicle settings for maximum fuel savings. Use this mode when possible, particularly during steady-state highway cruising or in low-speed city traffic. It adjusts throttle response, shift points, and even the climate control system to conserve fuel.

Avoid aggressive driving habits. Quick acceleration and hard braking consume significantly more fuel than smooth, gradual inputs. Anticipate traffic conditions, maintain a steady speed, and avoid unnecessary acceleration and deceleration. Gentle driving not only improves fuel efficiency but also reduces wear and tear on your vehicle.

Minimize idling time. Idling wastes fuel and contributes to emissions. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and the fuel saved by turning off the engine will outweigh the energy required to restart it.

Keep your vehicle properly maintained. Regular maintenance, including oil changes, filter replacements, and spark plug replacement, ensures that your engine runs efficiently. A poorly maintained engine will consume more fuel and produce more emissions. Follow the manufacturer’s recommended maintenance schedule to keep your A5 in optimal condition.
