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 Cadillac XT6 Premium Luxury AWD, new for 2020, is a nicely appointed - albeit pricey - midsized SUV in a vehicle category with many capable competitors. Our testers gave the XT6's exterior and interior styling and layout high marks, noting its particularly nice dashboard and the balance of hard and touch-screen soft keys on its center stack. The XT6 is powered by a 3.6-liter V6 engine with 310 hp, paired with a 9-speed automatic transmission. Ride quality and handling received high marks as well, aided by an AWD system that provides improved traction. The XT6's fuel-economy ratings (17 mpg city/24 mpg highway/20 mpg combined) are low, typical for a big SUV. And when going up steep driveways, it's easy to scrape the bottom of the car's front end. The XT6 comes equipped with a host of standard and available advanced driver-assistance systems, such as forward-collision warning, lane-keeping assist, automatic emergency braking, pedestrian detection, and night vision, to name a few.
