    Will a Plug-In Hybrid Save You Money?

    We've calculated the cost of owning three CR Recommended PHEVs, comparing them with their gas, hybrid, or EV counterparts

    A plug-in hybrid electric vehicle (PHEV) will almost always cost less to fuel than a conventional car and will usually cost less than a hybrid, too, says Jake Fisher, senior director of CR’s Auto Test Center. But on average, the purchase prices of PHEVs we tested were 15 percent higher than their gas-only counterparts and 13 percent higher than hybrids. Whether your fuel savings will cover the additional purchase cost depends on a number of factors.

    More on PHEVs

    We calculated for drivers who put 40 miles a day on their cars, plug in their EVs and PHEVs nightly, and take four 500-mile road trips each year. We assumed a blend of city and highway driving in optimal temperatures for electric range, used the latest fuel and energy prices available in January 2024, and chose gas and electric prices for states with energy costs that represent most of the country.

    "PHEVs give you the flexibility to pick whichever energy source costs less," Fisher says. But if you live somewhere with high gas prices and relatively low electricity costs, such as Washington state, we found that a PHEV will save you more money per mile than if you lived somewhere with lower gas prices and higher electricity prices, such as Massachusetts. The savings are less significant in states such as California, where electricity and fuel costs are high, and Florida, where both costs are relatively low.

    PHEV vs. Gas: BMW 3 Series

    The winner: PHEV

    In general, a PHEV will save you money on fuel over a gas-only version of the same vehicle as long as you regularly plug it in. The payback period depends on your fuel and energy costs. The BMW 330e PHEV costs $1,390 more than the conventional 330i. Even with a modest electric-only range of 20 miles, the 330e pays for itself in just under three years in Washington but over seven years in California.


    PHEV vs. Hybrid: Hyundai Tucson

    The winner: Hybrid

    By and large, a PHEV will cost more to purchase than a conventional hybrid. In the case of this Tucson, any fuel savings might not make up the $3,395 difference in cost—especially if electricity is expensive where you live.


    PHEV vs. EV: Kia Niro

    The winner: PHEV

    Fueling costs are similar between the two vehicle types, and EVs almost always cost more upfront to purchase than PHEVs. The Niro EV would make financial sense only if you could take advantage of state and local incentives that apply to EVs and not PHEVs, if the manufacturer is offering a lease deal on an EV, or if you have solar panels at home.
