Frequently Asked Questions

The average new car in 2024 gets about 28–32 MPG combined. SUVs typically get 22–26 MPG. Hybrids get 40–55 MPG. Electric vehicles are measured in MPGe (miles per gallon equivalent).

Maintain steady speed, use cruise control on highways, keep tires properly inflated, remove excess weight, and get regular maintenance. Aggressive acceleration and braking can reduce MPG by 15–30%.

Divide the trip distance by your MPG to get gallons needed, then multiply by the gas price. This calculator does it automatically.
