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 in the AAA Green Car Guide, which initially focused entirely on rating fuel-efficient, low-emitting vehicles.

For the 2021 edition, we've expanded the focus of the guide to 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 the development of autonomous vehicles.
