Fuel efficiency endures as a top criterion among new-car shoppers, but how do they know which cars are most fuel efficient? The U.S. Environmental Protection Agency tests new light vehicles and ranks them according to fuel mileage potential. Only pure electric vehicles, plug-in gas-electric hybrids and standard gas-electric hybrids made this list — here’s a look at the 20 models with the best combined EPA fuel-economy ratings. Notes: Annual fuel cost estimate based on 55% city / 45% highway driving and 15,000 annual miles. Electric vehicles ranked by Miles Per Gallon equivalent (MPGe): 33.7 kW-hrs = 1 gallon of gas. Vehicle prices listed do NOT include the federal tax credit of up to $7,500. Model year 2016 data shown when 2017 EPA data unavailable.

Starting MSRP: Not Released
MPGe (city/hwy/combined): 150 / 122 / 136
Charge time: 4 hours at 240V
Annual fuel cost: $500
Driving range: 124 miles
The Ioniq Electric is one of three different powertrain choices for Hyundai’s sleek new vehicle platform. The Electric’s 88kW (120-horsepower) electric motor sources power from a 28 kW-hour lithium-ion polymer battery. Charging the battery to 80 percent takes approximately 20 minutes using a 100-kW fast charger; as an alternative, an integrated in-cable control box also lets owners charge Ioniq from a standard household socket. In terms of design, the Electric version differentiates itself from the Hybrid and Plug-In via a clean grille surface, LED low-beam headlights and rear combination lamps that have a unique pattern.

Starting MSRP: $42,400
MPGe (city/hwy/combined): 137 / 111 / 124 (60 amp-hour battery)
Charge time: 4 hours at 240V
Annual fuel cost: electricity = $550
Driving range: 81 miles
On the market since 2014, the BMW i3 is available as a pure EV with a 60- or 94-amp-hour battery, or as a plug-in gas-electric hybrid. Although the i3 is not the cheapest entry-level EV, it is one of the coolest. Built on an aluminum frame with a carbon fiber body, the i3 has a low center of gravity and quick acceleration; it reaches 60 mph in just over 6 seconds. The 170-horsepower electric motor provides a range of 81 miles with the 60 amp-hour battery, but with the 94 amp-hour battery the range jumps to 114 miles. The plug-in gas-electric hybrid has a total range of 180 miles.

© General Motors2017 Chevrolet Bolt EV
Starting MSRP: $37,495
MPGe (city/hwy/combined): 128 / 110 / 119
Charge time: 9.3 hours at 240V
Annual fuel cost: $550
Driving range: 238 miles
Voted 2017 Motor Trend Car of the Year, the Bolt EV promises a range of more than 200 miles with a starting price calculated by GM bean counters to hit just below $30,000 when including the full $7,500 federal tax credit. The 200-mile range exceeds almost every other electric car currently on the market — the one exception being Tesla. However, the Bolt EV is about half the price of a Model S. In addition to its impressive stats, this new EV is loaded with innovations. A Bolt-specific Bluetooth low-energy system connects to a smartphone as the driver approaches the car. A large 10.2-inch touchscreen display and rear camera mirror are available, and a dedicated EV nav system plans a route while considering terrain that will affect the battery’s depletion rate. Social bonus: Bolt EV owners will be able to compete against each other and see who is driving most efficiently.

© Volkswagen of America, Inc.2016 Volkswagen e-Golf*
Starting MSRP: $28,995
MPGe (city/hwy/combined): 126 / 105 / 116
Charge time: 3.7 hours at 240V (7.2 kW charger)
Annual fuel cost: $550
Driving range: 83 miles
Considering all the issues surrounding their diesel engines, Volkswagen has decided to go long in electrification, vowing to have 30 EV models on roads by 2025. The German automaker says the e-Golf can hit 60 mph in a little more than 10 seconds, but it feels faster with its instantly-available 199 lb-ft of torque. The e-Golf is available at participating dealers in California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Vermont and Washington, D.C. *Note: The EPA has not posted data for the 2017 e-Golf.

© Nissan North America, Inc.2017 Nissan LEAF
Starting MSRP: $30,680
MPGe (city/hwy/combined): 124 / 101 / 112
Charge time: 6 hours at 240V
Annual fuel cost: $600
Driving range: 107 miles
The most significant change for the 2017 LEAF is battery size — the 30-kWh pack is the standard battery across the entire range. The larger battery provides a driving range of 107 miles, which Nissan says is a 27 percent increase over the previous LEAF battery. A favorite of corporate eco-fleets, the LEAF is a stalwart performer and well on its way to being the best-selling pure EV ever.

Starting MSRP: $31,800
MPGe (city/hwy/combined): 121 / 103 / 112
Charge time: 4 hours at 240V
Annual fuel cost: $600
Driving range: 84 miles
Quicker than its gas-powered sibling, the 500e is a blast to drive around the city. That said, the space needed for the battery renders the rear seat virtually unusable. The 2017 500e has Uconnect 5.0, which uses a 5-inch touchscreen and has Bluetooth capability. Availability continues to be exclusively in Oregon and California.

© Mitsubishi Motors North America, Inc.2017 Mitsubishi i-MiEV

A crossover SUV unlike any other on the market, the Model X’s unique powertrain resides at the core of this game-changer — although it’s not the only innovation. Two independently controlled electric motors power the all-wheel-drive Model X. The base 90D has a range of 257 miles and can reach 60 mph in a quick 4.8 seconds. One of the most notable innovations on the Model X are its Falcon Wing doors, which need only 12 inches of side clearance to operate. Inside, a medical-grade HEPA filter removes pollen, bacteria, viruses and pollution from the air before circulating it into the cabin. This versatile crossover can also tow up to 5,000 pounds. *Note: The EPA has not posted data for the 2017 Model X.
