TCC’s Bottom Line
The 2021 Acura RDX satisfies sport-sedan drivers and crossover needers alike with strong performance and scads of space. The 2022 Audi Q3 parks in the small-SUV space, but fills it to the lines with technology and safety. The 2022 Cadillac XT4 fits compact-car moves into a worthy entry-level SUV, but the interior could be better.
