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 2023 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

The LX 600 is Lexus’ biggest, most expensive SUV. In 2022 it replaced the venerable (but dated) LX 570. The LX 600’s twin-turbocharged V6 puts out plenty of power and has a higher estimated fuel-economy rating than its V8 predecessor. Its roomy, quiet cabin is exquisitely furnished with first-rate materials, and the Mark Levinson audio system delivers premium sound. Lexus provides a full complement of advanced safety features with its Safety System+ 2.5. We tested the top-level Ultra Luxury trim, which replaces the second-row bench seat with ultra-swanky captain’s chairs and eliminates third-row seating altogether—and loses some utility in the bargain. It seems designed mainly to chauffeur rear-seat passengers in high levels of comfort. Rare among large SUVs, the LX 600 is capable of venturing off the pavement. Drivers can choose from 6 off-road driving modes plus a crawl-control feature for improved traction at slow speeds. These features might be appropriate for lower trim levels, but let’s get real: How many owners are going to use a $130,000 vehicle as an off-road rock crawler? The LX 600 exhibits other missteps, such as its enormous grille, which detracts from its overall appearance. Inside, the dual-screen instrument/infotainment setup feels busy, nonintuitive, and outdated. Transmission shifts are rough, the ride is too soft and floaty, and large rear roof pillars limit side and rear visibility.
