TCC’s Bottom Line
Consider the 2018 Acura RDX if you’re after a budget-conscious crossover that rides and drives well. The Audi Q5 is certainly the segment's most modern offering, delivering a high degree of technology, comfort, and conservative style. The 2018 Lexus NX is an expressively styled and comfortable compact luxury crossover, but its mix of features faces significant new competitors this year.
