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

As BMW aficionados know, the automaker produces a seemingly endless variety of vehicles—nearly 20 models in all. The 4 Series coupe is basically a 2-door version of the popular 3 Series sedan, with the same 2.0-liter turbocharged 4-cylinder engine (255 hp) and 8-speed automatic transmission; it’s also available as a convertible. Redesigned for 2021, the current 430i picked up a few horsepower, and, most noticeably, a huge new grille that evokes an immediate love-it-or-hate-it response. The modern interior features a fully digital instrument cluster, and straightforward controls, including an iDrive infotainment system that’s easy to manipulate. In the performance department, the 430i checks most of the important boxes—a powerful engine and tight handling. Nits to pick? Value, for one. To get luxury basics like heated front seats, lumbar support, and keyless entry, for example, you have to shell out $3,200 for a Premium Package—this in a car with a base price north of $45,000. However, a suite of advanced safety features is standard, and 3 years/36,000 miles of maintenance is complimentary
