Gas mileage comparison
Compare fuel costs between vehicles side by side.
How to compare gas mileage
Comparing fuel economy between vehicles helps you understand the real cost difference. A car with better MPG doesn't just save you money at the pump, the savings compound over years of ownership.
Annual fuel cost = (Miles per year ÷ MPG) × Gas price
For example, driving 12,000 miles/year: a 25 MPG car costs $1,680/year in gas at $3.50/gal, while a 35 MPG car costs only $1,200/year: saving you $480 annually.
Average MPG by vehicle type
Use these as benchmarks when comparing vehicles:
- 🚛 Full-size trucks and SUVs: 15–20 MPG combined. Expect $2,100–$2,800/year in fuel at 12,000 miles.
- 🚙 Midsize SUVs and crossovers: 25–30 MPG combined. A solid middle ground at $1,400–$1,680/year.
- 🚗 Sedans and compact cars: 30–38 MPG combined. The most economical non-hybrid option at $1,100–$1,400/year.
- 🔋 Hybrids: 45–55 MPG combined. Under $1,000/year in fuel for most drivers.
What to consider beyond MPG
- ⛽ Fuel type matters. Diesel and premium gas cost more per gallon. A diesel car with better MPG might not save money if diesel costs 20% more.
- 🛣️ Your driving mix. If you mostly drive highway, the highway MPG rating matters more. City commuters should focus on city MPG.
- 📊 Real-world vs EPA ratings. EPA numbers are tested in a lab. Most drivers get 10–15% worse fuel economy in real conditions.
