Fuel economy is measured in miles per gallon (MPG) and varies by engine, transmission, body style, and driving conditions. Smaller, lighter vehicles typically use less fuel; trucks and large SUVs use more. Check the EPA fuel-economy label on every new car for city, highway, and combined MPG estimates.

### Shopping smart
Decide your priority: if you commute mostly highway, focus on highway MPG. If mostly city driving, city MPG matters more. Hybrid and electric vehicles offer better efficiency in stop-and-go traffic. Compare vehicles in the same class to see the range-for example, all compact sedans won't be identical.

### Real-world results
Actual MPG depends on your driving habits, maintenance, and road conditions. Proper tire pressure, regular service, and smooth driving boost efficiency.
