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

Acura isn’t the first automaker to come to mind when you’re considering midsize luxury vehicles. But if you dig a little deeper, you’ll come across the TLX, all new for 2021. It may not have the cachet of German rivals, but there’s no denying that it’s a rewarding sports sedan. In the looks department, this longer, wider TLX’s sleek styling will definitely turn heads. The upgrades continue inside, with a handsomely designed cabin replete with upscale materials. The highly supportive sport seats are very comfortable, but rear passengers may find their quarters a bit tight. There’s an abundance of technology, too, but using the console-mounted trackpad to access the features on the center-mounted display requires a steep learning curve. Propulsion comes from a 2.0-liter turbocharged 4-cylinder engine (272 hp) which, in the case of our test car, fed power to all 4 wheels via the automaker’s Super Handling All-Wheel Drive setup. Acceleration is brisk, but the engine noise and vibration doesn’t befit a luxury car, and the car’s considerable weight restricts performance and reduces fuel economy. However, the sport-tuned suspension delivers a good balance between crisp handling and ride comfort
