Verdict: The Mercedes‑AMG GLS 63 outpaces the BMW X7 M60i in straight‑line performance, posting 603 hp and a 4.1‑second 0‑60 (Car and Driver) versus 523 hp and 4.5 seconds for the X7. However, the X7’s lower price and slightly better fuel economy (18 mpg vs 16 mpg) give it stronger value (Edmunds). If outright speed and AMG branding are top priorities, the GLS 63 wins; for a more balanced luxury SUV with lower running costs, the X7 is the smarter pick.

BMW X7 M60i xDrive: 7.5/10
