Best MPG Cars for 2021

By Chris Teague | April 16, 2021

Fuel economy is rightfully a big point of focus for automakers, as tightening regulations and a struggling environment press them to make progress. The world of the electric car is set to explode in 2021, but the humble hybrid is available now and offers stellar fuel economy in familiar and already fuel efficient vehicles like the Toyota Camry and Honda Accord.

The upside to this is that people might be more inclined to buy a hybrid, due to the fact that they are strikingly similar to the standard gas cars with which they share a model name.

The downside is that hybrids can sometimes get lost in the shuffle and have a hard time breaking through all the hype surrounding more popular models.

Hybrid cars are worthy of more attention, however. Their ability to combine an electric motor, batteries, and a traditional gas engine to produce what is sometimes amazing gas mileage should put them on shoppers’ radars, but in many cases the hybrid versions are quicker and smoother than their gas-only counterparts.

Finding a good hybrid that delivers fun, comfort, and stellar fuel economy is easier than ever in 2021.

Here is our list of ten cars – all of which happen to be hybrids. All of these vehicles also return way more than the old-school gas mileage benchmark of 30 mpg.


2021 Honda Accord Hybrid

EPA Rating: Up to 48 mpg combined.

That is on top of a variety of desirable options and equipment that the car gets as standard kit. All Accord models get a full suite of advanced driver aids, such as lane keep assist, adaptive cruise control, traffic sign recognition, and automatic high beams. The cars are also well equipped with entertainment tech, such as an eight-inch touchscreen, Apple CarPlay and Android Auto, and a 160-watt sound system.

It is rated at up to 52 mpg combined, which comes from its 2.0-liter inline-four combined with a permanent magnet synchronous motor. The total system output lands at 192-horsepower, but it is the car’s fuel efficiency and standard equipment that stand out.

The Camry has been duking it out with the Honda Accord for decades, and the same is true on the hybrid front.

Making the Ioniq even more attractive is the fact that it carries a mainstream style that does not advertise its extreme fuel efficiency, which may be appealing to people just looking for a frugal ride to and from work each day. The Ioniq can also be purchased as a plug-in hybrid.

If you are curious about the fuel economy of a specific vehicle, fueleconomy.gov offers a quick way to search the EPA ratings for almost every vehicle in production today.

It is important to remember that, no matter how fuel-efficient they should be, commercial vehicles are not part of the search tool.

Any one of these hybrids will return great fuel economy, but keep in mind that there are plenty of traditional gas cars that are nearly as economical.

Many new cars are able to achieve unbelievable gas mileage without the use of batteries. The tradeoff for these types of cars usually comes in the form of power and performance, but for most people, searching for the best fuel economy usually does not involve looking for the most powerful vehicle around.

It is also important to note that many automakers are reducing the numbers of cars they make, in favor of more popular and profit-driving SUVs and crossovers. Ford is a great example of this, as The Blue Oval has opted to kill off most of its popular cars to build only the Mustang and GT supercar.

Thankfully, companies like Mazda, Volkswagen, Chevrolet, Mini, Nissan, and others continue to make fuel efficient cars with small engines and turbos to get the job done. Some even offer all-wheel drive and other luxuries not often found in fuel efficient cars.
