30 MPG combined is respectable for the 2020 Audi A4 2.0L 4-cylinder, a car aimed squarely at professionals and small families who want a premium driving experience. This isn’t a hybrid trying to rewrite the rules of efficiency, but a well-engineered sedan delivering solid fuel economy with the expected Audi refinement and performance.

City and highway performance

The A4’s EPA ratings break down to 27 MPG in the city and 35 MPG on the highway. The city figure reflects the A4’s nimble handling and responsive engine, making it well-suited for urban commutes. Stop-and-go traffic will naturally impact fuel economy, but the engine’s start-stop system helps reduce some of the losses. The 35 MPG highway figure is where the A4 excels, showing its ability to cruise efficiently on longer trips. Many owners will find this to be a very achievable number, especially with a light foot on the accelerator. This makes the A4 a good choice for those who regularly split their time between city and highway driving.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2020 Audi A4 2.0L 4-cylinder is $1,950. This calculation is based on driving 15,000 miles per year and using national average fuel prices. This number provides a useful benchmark for comparing the A4’s running costs against other vehicles, but individual spending will vary based on driving habits and local fuel prices. For those covering significantly more or less than 15,000 miles annually, adjusting this figure proportionally provides a more personalized estimate.

Real-world expectations

EPA estimates provide a good baseline, but real-world fuel economy can vary. The A4 buyer typically wants a balance of performance and efficiency. They’re likely to appreciate the responsive acceleration and German-engineered driving dynamics, rather than hypermiling techniques. Expect the real-world average to be somewhere around the EPA combined figure, maybe slightly lower if you frequently drive aggressively. Tire pressure, vehicle load, and driving style all play a significant role, and consistent maintenance is also key to preserving the A4’s fuel efficiency over the long term. You can view A4 MPG across all years.

How it compares

The A4’s fuel economy places it competitively within its class. Compared to the BMW 330i, which offers similar performance and luxury, the A4’s MPG figures are nearly identical. The Mercedes-Benz C300 achieves comparable numbers. However, a Lexus IS 300, while offering Lexus’s reliability, often falls slightly short of the A4’s MPG in real-world driving. For buyers cross-shopping these vehicles, fuel economy is often just one factor among many including styling, handling, and brand preference. If fuel economy is a top priority, a hybrid sedan might be a better choice, but understand that you will be giving up some of the A4’s driving dynamics. Consider checking all Audi fuel economy data before making your final decision.

Tips to maximize efficiency

Use the A4’s drive select modes carefully. In “Efficiency” mode, the car optimizes throttle response, transmission mapping, and climate control settings to minimize fuel consumption. While you might sacrifice a bit of responsiveness, it’s a great option for highway cruising or during periods of consistent low-speed driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Check your A4’s door jamb for the recommended tire pressure and make it a habit to check your tires regularly, especially during seasonal temperature changes.

Avoid unnecessary idling. Modern engines are designed to idle efficiently for short periods, but prolonged idling still wastes fuel. If you’re stopped for more than a minute, it’s usually more efficient to turn off the engine. The A4’s start-stop system is designed to handle this automatically in many situations.

Smooth acceleration and braking are key to maximizing efficiency. Avoid sudden bursts of speed or harsh braking. By anticipating traffic conditions and maintaining a consistent speed, you can minimize fuel consumption and improve your overall MPG.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and spark plug maintenance are essential for optimal engine performance and fuel efficiency. Follow Audi’s recommended maintenance schedule to keep your A4 running smoothly and efficiently for years to come.
