There are a lot of things Sarah Martens likes about the 2025 Toyota Highlander hybrid she bought a few months ago. Its pearlescent white paint shimmers in the sunlight. It has lots of safety features. And for a large sport utility vehicle, it sips gasoline, getting nearly 30 miles per gallon at times.

But the thing she likes most: It doesn’t feel like a hybrid.

“It’s so smooth,” said Ms. Martens, a Pilates instructor in Ann Arbor, Mich. “When it starts off from a stoplight or switches from electric to gas, I can’t tell I’m driving a hybrid. It just seems like I’m driving a normal car.”

Not so long ago, it seemed that the heyday of hybrids had come and gone. As Tesla and the potential of electric vehicles grabbed the imaginations of drivers and automakers, hybrids appeared destined to be remembered as an interim step on the way toward a fully electric, emissions-free future.

Just four years ago, for example, General Motors set a goal of ending production of all internal combustion models by 2035, and all but eliminated hybrids from its future product plans. Other manufacturers also bet heavily on electric vehicles and scaled their hybrid plans.

But then a funny thing happened. Car shoppers balked at the high prices of fully electric models and the challenges of charging them. In the last few years, sales of electric vehicles have grown at a much slower rate than automakers once expected. And hybrids have stepped in to fill the gap, accounting for a large and growing share of new car sales.

“People like the attributes that hybrids bring to the table,” said Jessica Caldwell, executive director of insights at Edmunds, a market researcher. “They offer better mileage than pure gasoline models, and the prices are pretty close to pure gas vehicles, so they’re much more affordable than E.V.s.”
