Most Fuel-Efficient Cars in America

Fuel-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.

20. 2017 Tesla Model X 75D
Starting MSRP: $85,500
MPGe (city / hwy / combined): 91 / 95 / 93
