When it comes to luxury, two names comes to mind immediately: BMW and Mercedes-Benz. When you're looking for a comfortable, luxurious SUV to support your growing family, you'll likely see the 2021 BMW X7 and Mercedes GLS in your research. Which will be right for you?

Our team at BMW of Rochester Hills has put together this quick comparison so all our friends in the Rochester Hills, Oakland Township, and Sterling Heights, Michigan, areas can make an informed decision on the right luxury SUV for them.

2021 BMW X7 vs. Mercedes GLS Engine Performance: Impressive Levels of Power

Both the 2021 BMW X7 and the Mercedes-Benz GLS offer three engines across three trim levels. The Mercedes GLS's 4.0L V8 biturbo with EQ Boost is available on the AMG GLS 63 trim. This powerful engine offers an impressive 603 horsepower and an EPA-estimated 14 city/18 highway MPG. These features create the ideal ride for getting the kids to and from their after-school activities.

The BMW X7's available 4.4L BMW ALPINA Bi-Turbo V8 engine, however, offers 612 horsepower with an EPA-estimated 15 city/21 highway MPG.1 This is a great mix of power and efficiency-perfect for getting the kids to school and you to work without that usual morning stop at the pump.

2021 BMW X7 vs. Mercedes GLS Dimensions: Room in the Garage

You're a busy professional, and you need a car that has presence on the road but also fits into those tight parking spots at work. Both the 2021 BMW X7 and the Mercedes-Benz GLS have impressive exteriors, but which fits your life-and that cramped parking garage-best?

Though the Mercedes GLS beats out the BMW X7 in size, bigger isn't always best. The almost two inches in length and over five inches in width could mean the difference between that choice spot right next to the front door or a long walk from the back of the lot.

2021 BMW X7 vs. Mercedes GLS: Comfort and Convenience

As expected with a pair of luxury vehicles, both the 2021 BMW X7 and Mercedes GLS come standard with a myriad of comfort and convenience features, such as:

  • Apple CarPlay™ and Android Auto™ integration
  • Power tailgate
  • Universal garage-door opener
  • Automatic 4-zone climate control
  • Heated front seats

However, if you want to ensure you have the connectivity you need-even on road trips through the great stretches of nowhere across the country-consider the BMW X7's standard Wi-Fi hotspot capability. This feature is available on the GLS, but you'll need to upgrade your model with the Mercedes me In-Car Wi-Fi package.

2021 BMW X7 vs. Mercedes GLS: Put the Luxury Giants to the Test Drive

Both the 2021 BMW X7 and the Mercedes-Benz GLS are undoubtably titans in the luxury SUV market, but which fits your lifestyle? If you want power, convenience, and the ability to fit into those cozy spaces in the car pickup lane at your kids' school, consider contacting BMW of Rochester Hills.
