The XT4 squares off well against German rivals such as the BMW X1 and Audi Q3, both of which are smaller but a little more polished in their moves and especially their interiors.
The slightly larger Mercedes-Benz GLB-Class offers room for more passengers in a pinch, and its boxy lines mean more cargo room as well.
Acura’s RDX has great moves paired with tech that may take a while for some drivers to master.
Though it’s been around for a while, the Volvo XC40 is fun, stylish, and well-realized inside for passengers and their cargo.
Don’t skip it.
