5 hybrid compact sedans with the best gas mileage

The five new compact hybrid sedans with the best highlights in the gas mileage guide:

  • Provided its battery is charged, the new compact hybrid sedan with the best gas mileage is the 2022 Hyundai Ioniq Plug-in Hybrid
  • The 2022 Hyundai Ioniq Hybrid Blue and Elantra Hybrid Blue take the No. 2 and No. 3 spots, respectively, among compact four-door hybrids
  • The 2022 Toyota Corolla Hybrid takes fourth place, while fifth place goes to the 2022 Honda Insight

On their own, compact sedans already know how to sip their fuel. But they can do it even better with hybrid aid. And they achieve this great gas mileage without the sacrifices made by the “economy cars” of decades past. Yet even within this fuel-efficient fleet, some models stand out for their efficiency. So if you’re shopping for compact hybrid sedans with the best gas mileage, the cars listed below should be on your list.

The 2022 Hyundai Ioniq Plug-in Hybrid has the best gas mileage of any new compact sedan when loaded

Although hybrids already benefit from better gas mileage than non-hybrids, plug-in hybrids go one step further. Because they can run on battery power alone and then recharge on gasoline, PHEVs offer similar benefits to electric vehicles with fewer drawbacks. And if their batteries are charged, they don’t burn fuel. That’s why the compact hybrid sedan with the best gas mileage is a plug-in sedan: the 2022 Hyundai Ioniq Plug-in Hybrid.

Like its non-plug-in sibling, the Ioniq Plug-In Hybrid features a 1.6-liter four-cylinder engine and a six-speed dual-clutch automatic transmission. But while the PHEV model also produces 139bhp, it gets a bigger lithium-ion battery and a more powerful electric motor. As a result, the Ioniq Plug-In Hybrid has a range of 29 miles on battery alone. And in combined electric and gasoline driving, it gets an EPA-estimated 119 mpge.

Certainly, the energy efficiency of the 2022 Hyundai Ioniq Plug-In Hybrid suffers if its battery runs out of charge. On gas alone, this compact hybrid sedan gets “only” a combined 52 mpg, according to the EPA. However, that’s still good for a range of 620 miles. Plus, it has the lowest running costs of any new hybrid.

Unfortunately, if you want one you’ll have to act fast, as Hyundai will discontinue it after 2022.

Among non-plug-in compact hybrid sedans, the 2022 Hyundai Ioniq Hybrid Blue gets the best gas mileage

Because of this PHEV transmission, the Hyundai Ioniq Plug-in Hybrid technically has the best gas mileage of any new compact hybrid sedan. However, there’s another compact four-door hybrid that beats its claims of dead-battery fuel economy. This would be the basis for the 2022 Hyundai Ioniq Hybrid, the Blue.

Although all non-PHEV Ioniq hybrids get great gas mileage, the blue trim is the best of the bunch. It gets an EPA-estimated 58 mpg city, 59 mpg combined and 60 mpg highway. In comparison, the other Ioniq Hybrid trims get 54 mpg city, 55 mpg combined, and 57 mpg highway. And the Ioniq Blue doesn’t just save you money at the pump – as stated before, it’s the cheaper version.

Unfortunately for fuel lovers, like the PHEV version, the Hyundai Ioniq Hybrid Blue will be phased out after 2022. So if you want to buy one of the most efficient new compact hybrid sedans, time is running out.

After 2022, the Elantra Hybrid Blue will be Hyundai’s most fuel-efficient compact car

Rest assured, compact hybrid sedan buyers, Hyundai will still have something to offer you next year. And if you can’t or can’t wait, you can its future holder of the “best gas mileage” compact hybrid crown, the 2022 Hyundai Elantra Hybrid Blue.

As with the Ioniq Hybrid, Blue is the base trim for the Elantra Hybrid. And as with the Ioniq, it’s also the most fuel-efficient form of the hybrid Elantra. The other trim, the Limited, gets an EPA-estimated 49 mpg city, 50 mpg combined, and 52 mpg highway. However, the 2022 Elantra Hybrid Blue gets 53 mpg city, 54 mpg combined, and 56 mpg highway.

If you’re willing to sacrifice some mpg, the 2022 Elantra Hybrid Limited has some nifty extra features. It has a larger touchscreen, for one, as well as a digital gauge cluster, 64-color ambient lighting and leather upholstery. But the Blue isn’t exactly sterile, although its interior is excessively plasticky, says MotorTrend. Still, it’s a neat way to save at the pump.

The 2022 Toyota Corolla Hybrid is the 4th four-door hybrid small car with the best fuel economy.

Although some consider the Prius a compact hybrid, Toyota itself describes it as a mid-size car. Also, it’s really a sedan, not a sedan, so it doesn’t belong on this list. But another Toyota, the 2022 Corolla Hybrid, does.

While not the most fuel-efficient Toyota hybrid, the 2022 Corolla Hybrid boasts one of the best gas mileage ratings among compact sedans. According to the EPA, it gets 53 mpg city, 52 mpg combined, and 52 mpg highway. And while it’s not as efficient as the Prius, it’s noticeably cheaper.

If gas mileage isn’t the only thing you’re concerned about, you might want to hold off on buying this compact hybrid sedan. For 2023, the Corolla Hybrid gets a new touchscreen, improved battery, additional safety features and optional all-wheel drive. This last characteristic will undoubtedly affect its fuel economy somewhat. However, it is not a checkbox. And the other upgrades will fix some of the car’s flaws, MotorTrend claims.

Waiting, however, is not an option for the latest compact hybrid sedan on this “best gas mileage” list. Much like the Ioniq hybrids, the Honda Insight is dead after 2022. But you can still save gas with one before the last one leaves the dealer lot.

Honda offers the 2022 Insight in two versions, and as with Hyundai hybrids, the base version is the most efficient. The Insight EX gets an EPA-estimated 55 mpg city, 52 mpg combined and 49 mpg highway. Meanwhile, the more luxurious Insight Limited gets 51 mpg city, 48 mpg combined and 45 mpg highway.

While not the most efficient compact hybrid sedan, the 2022 Insight is “an excellent sedan, period,” reports MotorTrend. Its rear headroom is a little compromised and its CVT drones a bit, but it rides and handles perfectly. Also, it has a plethora of storage spaces scattered everywhere. So while it doesn’t have the absolute best gas mileage among hybrids, there’s a lot to like about this sedan.
