BMW X7 vs Mercedes GLS Size Comparison: Which SUV Fits Your Lifestyle?

When it comes to premium luxury SUVs, the BMW X7 and Mercedes GLS stand out as top contenders, each offering commanding space and refined performance.

The Mercedes GLS, meanwhile, sets benchmarks in interior volume and rearmost legroom, measuring 197.7 inches—slightly longer than the X7—making it the spacious option in the segment. Powered by a robust V6 or hybrid powertrain, the GLS combines bold styling with advanced comfort features like rear-seat entertainment and ambient lighting. While both vehicles are similar in length, the GLS slightly edges out in rear passenger comfort due to its elongated cabin.

Ultimately, choosing between them depends on whether you prioritize compact efficiency (X7) or maximum room (GLS).
