Average MPG: What Different Vehicles Really Get
Is 28 MPG good? It depends entirely on what you drive. Here are the brackets.
Typical real-world MPG: compact sedans 30 to 36, midsize sedans 28 to 34, small SUVs 26 to 32, midsize SUVs 22 to 28, full-size trucks 16 to 22, hybrids 45 to 55. Your number depends on drive cycle, speed, and load as much as the vehicle.
Benchmarks by class
These are real-world figures, roughly 10 to 15 percent below EPA combined ratings. Compact and midsize sedans: high 20s to mid 30s. Small crossovers: mid to high 20s. Three-row SUVs: low to mid 20s. Full-size pickups: high teens to low 20s. Hybrids: mid 40s to mid 50s. Performance cars: whatever the fun costs.
What moves you within the bracket
Highway cruising at 65 beats 80 by 15 percent or more. City short trips in winter can halve a rating. Roof boxes cost 2 to 5 MPG at speed. Underinflated tires cost 1 to 2. All-wheel drive costs 1 to 2 versus the same model in front-wheel drive.
How to compare two cars honestly
Convert both to annual fuel cost: 15,000 miles / MPG x local gas price. A 25 MPG SUV versus a 35 MPG sedan at $3.20 is $1,920 versus $1,371 a year: $549 apart. That is the number to weigh against purchase price, insurance, and utility, not the MPG gap alone.
When below average signals a problem
If your car suddenly drops 15 percent or more with no change in driving, check tire pressure, air filter, and dragging brakes first. A stuck brake caliper or failing oxygen sensor can cost 5-plus MPG and will not fix itself.
Skip the arithmetic
Compare your measured MPG against your vehicle class.
Average MPG questions
What is a good MPG for a car?
For a gasoline sedan, 30 MPG or better is good. For a small SUV, mid-20s is good. For a full-size truck, breaking 20 is good.
What is the average MPG in the US?
New vehicles average around 26 MPG combined. The full on-road fleet, including older trucks and SUVs, averages in the low 20s.
Do hybrids really get double the MPG?
In city driving, hybrids often roughly double comparable non-hybrids because regenerative braking recovers stop-and-go energy. On highways the advantage shrinks to 20 to 40 percent.
Why is my MPG below average?
The usual suspects are short trips, high speeds, cold weather, extra cargo, and underinflated tires. A sudden large drop suggests a maintenance problem.
