2018 Acura RLX
KBB.com Review
Kbb.com Expert Rating
If you prioritize high-tech engineering and value over driving a luxury sedan that everyone immediately recognizes and envies, the 2018 Acura RLX is worth considering. Of the two trims, we recommend the RLX Sport Hybrid, which has standard all-wheel drive, more power, added features and higher fuel efficiency.
Compared to rivals, the RLX offers far fewer trims, doesn’t have CarPlay or Android Auto smartphone integration, and isn’t as well known. And while Acura vehicles have a good record of reliability, the RLX’s resale value is below average.
