Your 2020 Audi A4 should get 24-27 mpg in the city and 32-35 mpg on the highway, depending on whether you have front-wheel or all-wheel drive. If you're seeing lower numbers, several factors are likely at play.
Common Reasons for Lower Fuel Economy
EPA ratings assume ideal driving conditions. Real-world driving rarely matches this. Here's what affects your actual mileage:
Driving Habits Aggressive acceleration and hard braking waste fuel. Speeding over 50 mph reduces efficiency significantly. Frequent stops and starts drain your tank faster than steady highway driving.
Traffic and Road Conditions City driving with traffic lights and congestion uses more fuel. Stop-and-go traffic cuts efficiency compared to open highway driving. Cold weather also reduces mileage because your engine needs more energy to warm up.
Vehicle Maintenance Underinflated tires create more rolling resistance and hurt fuel economy. A dirty air filter makes your engine work harder. Worn spark plugs and misaligned wheels also reduce efficiency. Check your tire pressure monthly and follow your A4's recommended maintenance schedule.
Vehicle Load and Settings Extra weight in your trunk reduces efficiency. Running your air conditioner consumes fuel. Roof racks and cargo carriers increase wind resistance. Using premium gasoline (required for your A4) ensures optimal performance, but won't improve mileage beyond EPA estimates.
What You Can Do
Start with these steps to improve your fuel economy:
- Check tire pressure and inflate to the recommended PSI listed in your driver's door jamb
- Drive smoothly and avoid rapid acceleration
- Reduce highway speeds to 55-60 mph when safe
- Remove unnecessary items from your trunk
- Schedule regular maintenance including air filter replacements
- Avoid using cruise control on hilly terrain
Most owners who improve their driving habits see fuel economy closer to EPA ratings. If your mileage is significantly lower despite these changes, have a mechanic inspect your A4 for maintenance issues.
