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 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.

How The Car Guide Rating Works

Test Results and Rankings:
The green cars tested by the ARC are evaluated on the basis of 13 categories: emissions, fuel economy, crashworthiness, braking, acceleration, handling, cargo-carrying capacity, ride quality, interior noise, ease of entry and exit, maneuverability, roominess, and visibility. The scores for the categories are totaled, and the cars are ranked from high to low.

Overall Observations
The Prius Prime is the plug-in version of the iconic Toyota Prius hybrid. It costs about $3,000 extra, but many car buyers think it's worth it, especially if they drive less than 25 miles a day, which would be covered by the Prime's all-electric range. The Prime's interior is spacious, with comfortable and supportive front seats and very good front headroom. Visibility to the rear is compromised by a horizontal bar across the back window, however. The center stack is dominated by an available high-tech 12-inch by 6-inch display, which is somewhat difficult to use and prone to misoperation because of its small switches. The hybrid powertrain combines a 1.8-liter 4-cylinder engine with an electric motor and an 8.8-kWh lithium-ion battery. Total system output is just 121 hp, resulting in slow acceleration. The powertrain is smooth but noisy under load; the ride is comfortable but firm. Fuel economy in combined driving is 54 mpg in hybrid mode and 133 MPGe in all-electric mode. New in 2020 is a backseat that seats three instead of just two, and standard Apple CarPlay and Android Auto.
