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

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

Minivans don’t get the love and respect they did back in the early 2000s. But the Toyota Sienna Hybrid, redesigned for 2021, continues to thrive as a well-recognized staple in the minivan segment. The redesigned Sienna’s most outstanding feature is the fact that it’s available only as a hybrid (woohoo!). There’s a downside, though: The hybrid powertrain produces just 245 hp, compared with the 296 hp of the previous edition’s V6. That makes the Sienna Hybrid feel much slower - and the powertrain is noisy as well. But the gas-electric powertrain achieves an EPA-estimated 36 mpg in combined driving, compared with just 21 mpg for the previous generation - that’s huge. The Sienna delivers a smooth, comfortable ride for 7 to 8 people and their gear, although maneuvering a vehicle this big takes some practice. Our base model LE tester lacked some niceties we’d have liked - such as heated and cooled front seats and a power liftgate. However, LED headlights, 3-row automatic climate control, and Toyota’s Safety Sense 2.0 suite of advanced safety features are standard issue
