Fuel economy is measured in miles per gallon (MPG)-how many miles you travel on one gallon of gas. Higher MPG means fewer fill-ups and lower fuel costs over time.

**How it works:**
EPA ratings come in city (stop-and-go driving), highway (steady speeds), and combined. Check the window sticker or EPA website for official figures. Real-world results vary based on your driving habits, traffic, terrain, and how well you maintain the vehicle.

**Quick wins:**
Sedans and compact cars typically beat larger SUVs in MPG. Hybrid models (which pair a gas engine with electric power) deliver even bigger savings. Keeping tires inflated, regular maintenance, and steady driving all boost your actual MPG.

**The math:**
A car that does 25 MPG versus 30 MPG doesn't sound like much-but over 100,000 miles, that's a real difference in your wallet.
