When you're shopping for a car — or wondering if your current one is burning too much gas — MPG (miles per gallon) is the number that matters most for your fuel costs. But "good" is relative. A 30 MPG rating is excellent for a full-size truck and mediocre for a compact sedan. This guide gives you real benchmarks so you know exactly where your car stands.
MPG tells you how many miles your car can travel on a single gallon of fuel. A car rated at 35 MPG combined will travel 35 miles for every gallon burned. The higher the number, the more efficient the car — and the less you spend on gas over time.
The EPA tests every new vehicle and assigns two ratings: city MPG (stop-and-go driving) and highway MPG (steady freeway speeds). The combined MPG is a weighted average — 55% city, 45% highway — and is the most useful single number for comparison.
The EPA's combined MPG rating is calculated as a weighted average of 55% city driving and 45% highway driving. Real-world MPG is typically 15–20% lower than the EPA estimate depending on your driving habits.
There's no single answer to "what is good MPG" because the standard varies dramatically by vehicle class. Here's a breakdown by type:
| Vehicle Type | Poor MPG | Average MPG | Good MPG | Excellent MPG |
|---|---|---|---|---|
| Compact Sedan | Below 28 | 28–32 | 33–38 | 39+ |
| Midsize Sedan | Below 24 | 24–29 | 30–35 | 36+ |
| Compact SUV / Crossover | Below 24 | 24–28 | 29–33 | 34+ |
| Midsize SUV | Below 20 | 20–24 | 25–29 | 30+ |
| Full-Size SUV / Minivan | Below 16 | 16–20 | 21–24 | 25+ |
| Compact Pickup Truck | Below 20 | 20–24 | 25–28 | 29+ |
| Full-Size Pickup Truck | Below 15 | 15–19 | 20–23 | 24+ |
| Sports Car / Performance | Below 18 | 18–22 | 23–27 | 28+ |
| Hybrid Sedan | Below 40 | 40–48 | 49–55 | 56+ |
| Plug-In Hybrid (gas mode) | Below 35 | 35–42 | 43–50 | 51+ |
These ranges reflect 2026 EPA ratings for new vehicles in each category. If your car is older, slightly lower numbers are normal — engines lose some efficiency over time, and older models had lower baseline standards.
The average fuel economy of new vehicles sold in the US in 2025 was approximately 26–28 MPG combined across all types. That includes trucks and SUVs, which have dragged the fleet average down even as sedans and hybrids have improved significantly.
If you're driving a non-hybrid passenger car and getting less than 28 MPG combined, your car is below the current fleet average. That doesn't necessarily mean something is wrong — older cars and larger engines naturally score lower — but it does mean you're spending more on fuel than most new-car buyers.
Find your car's real fuel efficiency based on your fill-ups and mileage — not just the EPA estimate.
Use the MPG Calculator →The EPA estimate is a useful benchmark, but most drivers see lower numbers in practice. The gap between EPA and real-world MPG exists because:
The most accurate way is to calculate it manually from your fill-ups:
For example: if you drove 320 miles and added 11.5 gallons, your real-world MPG is 320 ÷ 11.5 = 27.8 MPG. Do this 2–3 times and average the results for the most accurate picture.
A gap of 10–15% below EPA is normal. If you're seeing 20–30% below the rated figure, something may be off. Common causes include:
A basic tune-up addressing these items can often recover 10–15% of lost fuel economy on a high-mileage vehicle.
At $3.40 per gallon (the approximate US average as of mid-2026), the difference between a 25 MPG car and a 35 MPG car on 15,000 miles per year is significant:
| MPG | Gallons Used (15K miles) | Annual Fuel Cost | 5-Year Fuel Cost |
|---|---|---|---|
| 20 MPG | 750 gallons | $2,550 | $12,750 |
| 25 MPG | 600 gallons | $2,040 | $10,200 |
| 30 MPG | 500 gallons | $1,700 | $8,500 |
| 35 MPG | 429 gallons | $1,458 | $7,291 |
| 40 MPG | 375 gallons | $1,275 | $6,375 |
| 50 MPG (hybrid) | 300 gallons | $1,020 | $5,100 |
The difference between a 20 MPG vehicle and a 35 MPG vehicle is about $1,100 per year in gas costs, or $5,500 over five years. This is why MPG matters more than many buyers realize — it's a cost that compounds every year you own the car.
Going from 20 MPG to 25 MPG saves more fuel per year than going from 35 MPG to 50 MPG. Improving efficiency is most impactful at the lower end of the scale.
Hybrid vehicles use the same MPG scale as gas cars — the Toyota Camry Hybrid, for example, gets around 51 MPG combined. Plug-in hybrids (PHEVs) run on electricity for short trips and switch to gas, so they have both an electric range and a gas-mode MPG rating.
Electric vehicles use MPGe (miles per gallon equivalent), a unit that converts the energy content of electricity into a gasoline equivalent. A car rated at 120 MPGe is extremely efficient; most EVs fall in the 80–130 MPGe range. However, MPGe and MPG aren't directly comparable for cost purposes — electricity costs much less per mile than gasoline for most drivers.
