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
To be clear right up front: The Cadillac CT5 is no sport sedan. Better instead to look at it as heir to all the things the GM luxury brand has stood for over the years, including classy good looks, a comfortable ride, and upscale amenities. Although the midsize CT5 has generally secure handling, the reality is that this sedan feels and drives like the heavy car it is. What it lacks in nimbleness, though, it makes up for with a luxury-car ride and an available 3.0-liter twin-turbocharged V6 (335 hp) that delivers attention-getting acceleration. From the driver's seat, you'll appreciate some unexpected creature comforts, like a wireless phone-charging pad and a 10-inch infotainment touch screen with an Apple CarPlay/Android Auto smartphone interface. Our test car was decked out with a long list of desirable options, including an oversize panoramic sunroof, heated/cooled front seats with massage, and a host of driver-assistance features, including adaptive cruise control and rear automatic emergency braking. The interior offers spacious accommodations up front, but taller passengers may find headroom limited in the rear seats. It's also worth noting that the CT5 has a relatively small trunk, with just under 12 cubic feet of cargo space.
