Make Your Commute More Fuel-Efficient With These Sedans

Among the many things to consider when shopping for a new car, fuel economy is an especially important one. Choosing a more fuel-efficient model today can have a big effect on operating costs down the road. If – or rather, when – gas prices increase, the savings will be that much greater.

Some of the most fuel-efficient models use a plug-in hybrid powertrain, which combines a gasoline engine with an electric motor and battery that can be plugged in to charge at home or on the road. As a bonus, plug-in hybrids can often be driven 20 miles or more on electric power alone. Examples include the Honda Clarity and the Toyota Prius Prime.

Some conventional hybrids, meanwhile, can return more than 50 mpg, and tend to have be cheaper than plug-in hybrid vehicles (PHEVs). The Hyundai Ioniq, for example, is EPA-rated at 58 mpg combined, while the excellent Toyota Camry Hybrid returns an impressive 52 mpg overall.

On the following slides, we’ve gathered up the most fuel-efficient sedans from our ranking of hybrid and electric cars. Most vehicles on this list are made by mainstream brands, but you'll find a couple of luxury models sprinkled in, as well. We’ve ranked them primarily in order of their EPA-estimated annual fuel costs, from highest to lowest. The EPA estimates assume 15,000 miles of driving per year, and a combined 55/45 percent city/highway driving mix.
