Most Fuel-Efficient Cars in America

© Hyundai Motor AmericaFuel-Efficient of 2018
Electrified vehicles continue to be the most fuel efficient in America, and in 2018 there are more plug-in models to choose from than ever before. But with relatively low gasoline prices, sales of pure electric cars remain a mere fraction of their gasoline-powered counterparts, largely due to the primary drawbacks of electric cars — the time they take to recharge, and how far they can travel on a single charge. All 20 vehicles on this most fuel-efficient list have some level of electrification; either pure electric or plug-in hybrid. What follows are the most fuel-efficient vehicles in America, sorted in ascending order by combined MPGe (miles per gallon equivalent, which measures the miles a vehicle can travel on the energy equivalent to a gallon of gasoline). Note: the EPA does not report city / hwy fuel economy for plug-in hybrids.

Starting MSRP: $85,500
MPGe (city / hwy / combined): 91 / 95 / 93
Range: 238 miles
As the only fully-electric crossover on the market, the Model X certainly stands out from the crowd in both style and capability. The Model X offers impressive performance both in efficiency and acceleration, thanks to its two independently-controlled electric motors for full-time all-wheel drive. Available with three different power levels, the Model X 75D is listed as the most efficient, according to the EPA. The 75D may feature the base-level power, but it can still accelerate to 60 mph in under 5 seconds. Slightly less efficient, the Model X P100D provides acceleration on par with most exotic sports cars. Sporting aerodynamic styling, innovative Falcon Wing doors and a versatile interior, the Model X is unique within the American crossover market.
