The Mercedes-AMG GLS63 is the kind of vehicle nobody asked for, but Mercedes built it anyway because it can. The rationale for this thinking: Who needs another three-row luxury SUV from Mercedes when we already have the GLS450 and GLS580? Maybe the cool moms and dads who want sports car performance in a Clifford the Big Red Dog-size SUV. Or the millennial investor who is trying to impress his entourage by showing them what a nearly 3-ton sport utility can do on back roads.
In any case, we put a 2021 Mercedes-AMG GLS63 through our battery of track testing, drove it on the intense streets of Los Angeles, and had some fun with it on scenic roads in Santa Clarita and Pasadena for a complete evaluation. We wanted to know if the sleeper of luxury SUVs merits a $153,125 price tag and lives up to the AMG nameplate. Does it? Read on to find out.
