The 2018 Audi A4 quattro 2.0L gets 27 MPG combined, which is a practical compromise. It isn’t a hybrid focused on ultimate efficiency. It’s a German sport sedan for drivers who want confident handling, a refined interior, and year-round capability. The fuel economy is good enough, so drivers aren’t disappointed while still getting an engaging experience.

City and highway performance

The EPA estimates the A4 quattro gets 24 MPG in the city and 34 MPG on the highway. The city figure shows what happens in stop-and-go driving, where the 2.0L turbo engine and seven-speed S tronic dual-clutch transmission are constantly shifting and adjusting. The quattro all-wheel-drive system adds weight and complexity, which slightly reduces efficiency compared to the front-wheel-drive A4. On the highway, the engine settles into its most efficient range, taking advantage of its tall gearing and relatively low drag. This A4 is best on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Audi A4 quattro 2.0L at $2,150. This is based on driving 15,000 miles per year using national average fuel prices. Your actual spending will vary depending on your driving habits and local fuel costs. This is a useful benchmark for budgeting. Premium fuel is recommended for the best performance, which will impact your real-world costs.

Real-world expectations

The EPA provides a standard estimate, but real-world fuel economy can vary. Aggressive driving, frequent short trips, and cold weather can negatively impact efficiency. Gentle acceleration, consistent highway speeds, and proper tire inflation can help you get close to or even exceed the EPA estimates. Owners who track their fuel economy often report numbers within a few MPG of the EPA combined rating, showing the A4’s efficiency is achievable with good driving habits. Don’t expect Prius-like numbers, but responsible operation won’t be excessively expensive.

How it compares

The 2018 Audi A4 quattro competes with other luxury sport sedans. The BMW 330i xDrive, a common rival, has similar performance and all-wheel drive, with EPA estimates around 23 MPG city and 33 MPG highway. The Mercedes-Benz C300 4MATIC gets approximately 23 MPG city and 31 MPG highway, trading some highway efficiency for a smoother, more comfort-oriented ride. The Acura TLX SH-AWD isn’t a direct competitor in terms of brand reputation, but it provides all-wheel drive and a more affordable price, achieving around 21 MPG city and 30 MPG highway. For buyers who want to minimize gas consumption, the Lexus IS 300h hybrid, not available with AWD, gets a combined 41 MPG, showing the gains possible with electrification. The A4’s fuel economy is competitive but not exceptional, reflecting the balance between performance, luxury, and all-weather capability.

Tips to maximize efficiency

Use the Audi Drive Select system. In “Efficiency” mode, the A4 will change engine and transmission settings for maximum fuel economy. This includes earlier upshifts, reduced throttle response, and coasting. It can improve your MPG, especially during highway driving, even though it might reduce the car’s sporty feel.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check the sticker on the driver’s side doorjamb for the recommended tire pressure and use a reliable gauge to ensure accuracy. Keeping your tires properly inflated is a simple way to improve fuel economy and extend tire life.

Avoid aggressive acceleration and braking. Smooth, gradual inputs are important for maximizing fuel efficiency. Anticipate traffic flow and maintain a consistent speed when possible. Hard acceleration and sudden braking waste fuel and cause wear and tear on your vehicle.

Consider premium fuel. The A4 can run on regular fuel, but Audi recommends premium for the best performance and efficiency. Premium fuel’s higher octane rating allows the engine to operate at its peak, potentially resulting in slightly better fuel economy and increased power.

Minimize unnecessary weight. Carrying extra cargo in your trunk or roof rack increases the vehicle’s weight, impacting fuel economy. Remove items you don’t need regularly, such as golf clubs, sporting equipment, or unnecessary tools. A lighter vehicle is more fuel-efficient.
