The most reliable way to get 40 MPG or higher today is by choosing a hybrid or a modern diesel vehicle. While some conventional gasoline-powered subcompacts can approach this figure on the highway, hybrids consistently achieve these numbers in combined city and highway driving, making them the most practical choice. For those open to electric driving, plug-in hybrids (PHEVs) can exceed the equivalent of 100 MPGe, while full electric vehicles (EVs) eliminate gas stops entirely.
The following table provides a clear comparison of 2024 models that reliably meet or exceed the 40 MPG benchmark, based on official EPA estimates.
| Vehicle Model | Powertrain Type | Combined MPG | City MPG | Highway MPG | Key Feature |
|---|---|---|---|---|---|
| Prius | Hybrid | 57 | 57 | 56 | Sleek redesign, improved power |
| Hyundai Elantra Hybrid | Hybrid | 54 | 53 | 56 | Feature-rich, great warranty |
| Toyota Camry Hybrid | Hybrid | 52 | 51 | 53 | Midsize sedan comfort |
| Honda Accord Hybrid | Hybrid | 48 | 48 | 47 | Spacious interior, refined ride |
| Kia Niro | Hybrid | 53 | 53 | 54 | Crossover versatility |
| Ford Maverick Hybrid | Hybrid (Pickup) | 42 | 42 | 33 | Only hybrid pickup truck |
| Chevrolet Malibu | Conventional Gas | 39 | 32 | 49 | Near-miss, high highway mileage |
| BMW 330i xDrive | Mild Hybrid (Diesel) | 40 | 35 | 47 | Luxury diesel option |
Understanding MPG and Your Needs
It's crucial to differentiate between combined MPG (a weighted average of city and highway) and individual figures. A car with a high highway MPG but lower city MPG might not average 40 MPG if you do a lot of stop-and-go commuting. This is where hybrids excel, as their regenerative braking system captures energy during city driving to boost efficiency.
The Plug-In Hybrid and Electric Alternative
If your daily commute is under 30-40 miles, a Plug-in Hybrid Electric Vehicle (PHEV) like the Toyota Prius Prime (127 MPGe) can cover most trips on electricity alone, effectively offering infinite MPG for daily use. For total freedom from the pump, a Battery Electric Vehicle (BEV) like the Hyundai Ioniq 6 converts efficiency into MPGe (Miles Per Gallon Equivalent), often exceeding 140 MPGe.
Your best bet for guaranteed 40 MPG is a hybrid. Your choice should factor in vehicle size, budget, and whether you have a place to plug in a PHEV or EV.

My daily commute is a killer, so 40 MPG was my non-negotiable. I went with the Elantra Hybrid. I'm consistently averaging 52 MPG in mixed driving without even trying hard. It's not a spaceship inside, but it has Apple CarPlay, comfortable seats, and everything just works. For saving a ton of money on gas while still having a normal, comfortable car, it's been perfect. I barely think about gas stations anymore.

Don't overlook diesel if you do a lot of highway miles. I drive a Equinox with a diesel engine for my sales territory. On the open road, it easily cruises past 40 MPG and has way more torque for passing than a gas engine. The fuel cost is sometimes a bit higher, but the range is incredible—over 600 miles on a tank. It's a different kind of efficient, but for the right driver, it's a brilliant solution.

We needed a car that could fit two kids and all their gear but didn't want a gas-guzzling SUV. The Camry Hybrid was the answer. It's a full-size sedan that gets over 50 MPG. The trunk is huge, the ride is super smooth and quiet, and we only fill up once every couple of weeks. It proves you don't have to sacrifice space and comfort to hit that 40 MPG goal. It's the family car that doesn't feel like a compromise.

As someone who tracks every dollar, my advice is to think beyond the sticker price. A car that gets 40 MPG versus 25 MPG saves me over $700 a year in gas, and that's real money. I leased a Niro because the technology is proven, and the warranty is long. It's a small SUV, so it's practical, but the hybrid system is the star. For a budget-focused person, the math is simple: higher MPG means lower running costs, which frees up cash for other things.
