Fuel economy measures how far a vehicle can travel on a given amount of fuel. Understanding your vehicle's efficiency helps you save money and reduce environmental impact.
| Measurement | Used In | Description |
|---|---|---|
| MPG (US) | United States | Miles per US gallon (3.785 L) |
| MPG (UK) | United Kingdom | Miles per Imperial gallon (4.546 L) |
| L/100km | Europe, Canada, Australia | Liters needed per 100 kilometers |
| km/L | Japan, India, some Asia | Kilometers per liter |
US MPG to L/100km: 235.215 × MPG
L/100km to US MPG: 235.215 × L/100km
UK MPG to US MPG: UK MPG × 0.833
Example: 30 US MPG = 7.84 L/100km
Maintain consistent speed and use cruise control on highways. Aggressive acceleration wastes fuel.
Save 10-20%Keep engine tuned, air filters clean, and use recommended oil grade. Proper maintenance improves efficiency.
Save 5-10%Check tire pressure monthly. Under-inflated tires increase rolling resistance and reduce MPG.
Save 3-5%Air conditioning uses extra fuel. At lower speeds, open windows; at highway speeds, use AC (less drag).
Save 5-15%Every 100 lbs reduces fuel economy by about 1%. Remove unnecessary cargo and roof racks.
Save 1-3%Combine trips, avoid rush hour, and use GPS to find the most efficient routes. Less idling = more savings.
Save 5-10%| Vehicle Type | City MPG | Highway MPG | Combined |
|---|---|---|---|
| Compact Car | 28-32 | 35-42 | 30-35 |
| Midsize Sedan | 24-28 | 32-38 | 27-32 |
| SUV | 18-24 | 24-30 | 20-26 |
| Pickup Truck | 15-20 | 20-25 | 17-22 |
| Hybrid | 45-55 | 40-50 | 45-52 |
| Electric (MPGe) | 100-130 | 90-110 | 100-120 |
The US EPA tests and publishes official fuel economy figures for all new vehicles. These are the 2025×2026 model year averages by vehicle category, along with annual fuel cost estimates at the national average gas price of $3.25/gallon:
| Vehicle Type | City MPG (avg) | Highway MPG (avg) | Est. Annual Fuel Cost |
|---|---|---|---|
| Compact car (non-hybrid) | 28×32 | 35×42 | $1,300×$1,600 |
| Compact hybrid (Toyota Camry Hybrid) | 44×52 | 47×53 | $850×$1,000 |
| Midsize SUV (non-hybrid) | 20×24 | 27×32 | $1,900×$2,400 |
| Full-size pickup truck (4WD) | 14×18 | 18×22 | $2,800×$3,500 |
| Electric vehicle (EV) × full BEV | equivalent 90×130 MPGe | equivalent 85×120 MPGe | $450×$700 (electricity) |
| Minivan | 19×22 | 25×29 | $2,000×$2,500 |
