If you’re feeling squeezed at the gas pump, you’re not alone. Gas prices are inching closer to their all-time highs once again, and this has a significant impact on what it costs to own a vehicle. The average price of fuel has increased by over 77% over just the last 5 years. This guide reviews the best gas mileage cars to consider if you’re looking to save money or reduce your carbon footprint. 

Best Gas-Only Cars For Fuel Efficiency

The primary trade-off you make with most gas-efficient cars is power. Most fuel-efficient cars with gas-combustion aren’t necessarily as sporty and responsive as a traditional muscle car. If a powerful performance vehicle brings you joy, consider some of the best electric cars which can hit 0 to 60 speeds in under four seconds.

Fuel economy isn’t the only thing that affects the cost of owning a vehicle. Some vehicles are more expensive to insure or repair, so be sure to consider the age and condition of a vehicle and get an insurance quote before you buy a used car. Surprisingly, many of the best fuel-efficient cars are more expensive to insure. You can often reduce the cost of your insurance premium by selecting vehicles with enhanced safety features. 

Here are the top picks in fuel efficiency for gas-only cars based on manufacturer data, the NHTSA and IIHS Safety Ratings:

Best Electric Cars For Mileage Range

Plug-in hybrids and full-electric vehicles are more expensive but offer considerable fuel savings over time. Be sure to factor in increased insurance costs, utility bills and repair bills when shopping for an electric vehicle. The MPG equivalent (MPGe) estimates the cost of charging your vehicle comparatively with the expense of filling a tank with gas. 

You need to either charge your vehicle at home or find a charging station, so consider how many charging stations you have access to where you live and the range of the electric vehicle. If you intend to travel frequently, you need a car that can go the distance.  

Here are the top picks in fuel efficiency for electric cars based on manufacturer data:

Top Pick: Tesla Model S Long Range

Choosing a more economical trim means less power but gives a range of up to 412 miles, making it ideal for road trips, and you still get plenty of luxury amenities. It also has available all-wheel drive and advanced safety features. 

You can get about 34 miles of range per hour of charge at home, which means you’re able to charge it completely overnight. If you charge it at a Supercharger station on the road, you can get 200 miles of range in 15 minutes. The estimated battery life is between 300,000 – 500,000 miles. 

Compared to a gas vehicle with a fuel rating of 24 mpg, the 2021 Model S can save you $18,160 over 10 years on fuel expenses. If you compare it with a hybrid that offers a combined 44 mpg, it can still save you $7,700 in fuel expenses over 10 years.*
