Introduction:

To help members understand the latest automotive technology so they can purchase vehicles that best suit their needs, the Automobile Club of Southern California's Automotive Research Center (ARC) began testing and reviewing vehicles over a decade ago

For the 2022 edition, we include testing and ranking cars and light trucks with the latest technology, including having at least one advanced driver-assistance system (ADAS) feature. In addition to vehicle evaluation, the guide covers a number of pertinent automotive topics in detail—for example, the latest advanced safety features, how to properly maintain your vehicle, and new vehicles coming to market in the next few years.

Overall Observations

The Prius Prime plug-in hybrid, which debuted in 2017, is the most recent addition to the Prius lineup. It combines a fuel-efficient 1.8-liter 4-cylinder gasoline engine, an electric motor (121 hp total), and a larger, rechargeable battery pack. This enables the Prime to travel farther (about 25 miles) on battery power alone, which is only middling in today’s PHEV world. Overall fuel economy, however, is awesome—54 mpg. Additional strong points include LED headlights, ToyotaCare maintenance (free for 2 years/25,000 miles), and the Toyota Safety Sense 2.0 suite of advanced safety features. High fuel economy comes at a cost, however. The Prius Prime’s hybrid powertrain feels underpowered and exhibits throttle lag. The interior is roomy, but the styling is uninspired. The front seats aren’t particularly comfortable, getting in and out of the backseat is difficult, and the cargo area is small when the seat backs are up. Rear visibility is also limited by the rear window’s angle and the horizontal partition across its center.
