Toyota Prius

With the proliferation of hybrid vehicles throughout the new-car market, the Prius’s appeal had been diluted by the early 2020s. Toyota took a radical approach with the car’s 2023 redesign — it made the Prius much sleeker, sexier and sportier. Front-wheel-drive models now produced 194 horsepower, and all-wheel-drive versions made 196 hp — a significant increase over previous generations. Fuel efficiency remained a strong suit, with the base model achieving an estimated 57 mpg combined. The dramatic new look and enhanced performance were aimed at broadening the car’s appeal beyond just traditional hybrid buyers, but it had downsides, as well. The new low-slung body shape significantly compromised interior space, with less headroom and cargo capacity compared to the outgoing model. 

Along with updated styling, the Prius grew for 2016, increasing cargo space. A new platform improved handling and ride. Though output from the carryover engine decreased slightly, fuel economy estimates increased to 54 mpg in the city and 50 mpg on the highway thanks to lighter hybrid components; an Eco version was even more efficient. Lithium-ion batteries were used on some variations.

A 2010 redesign retained similar styling but made the Prius slightly longer and more aerodynamic. A new 1.8-liter four-cylinder engine contributed to a total system output of 134 horsepower, yielding 51 mpg in the city and 48 mpg on the highway. The interior was significantly improved, as was handling. Toyota also added new drive modes, extending electric-only operation and maximizing fuel economy. Five trims and three option packages were available, and seven airbags became standard.

The Prius picked up its trademark hatchback configuration for 2004, moving from a compact to a mid-size with improved backseat room. Horsepower from the gas engine and electric motor increased to 76 and 67 hp, respectively. First advertised at 60 mpg in the city and 51 mpg on the highway, the numbers went to 48/45 with revised EPA ratings. A new gear shifter added a “B” for engine braking. Safety ratings improved, and side airbags were standard.

Debuting in the U.S. as a compact sedan, the Prius had a 1.5-liter four-cylinder engine making 70 hp, paired with a 44-hp electric motor with nickel metal hydride batteries. It was rated 52/45 mpg city/highway on the old EPA rating system, later revised to 42/41. The first Prius was criticized for its nonlinear brake feel, abnormal tire wear and subpar safety ratings.
