The 2020 Audi Q7 received some major updates for 2020, but the 2020 Mercedes-Benz GLS is all-new! With seating for seven, both of these two German SUVs are very popular with the South Riding region’s growing families. Still, you might wonder which model actually has more to offer! Compare the Audi Q7 vs. Mercedes-Benz GLS below, and make the right choice for your daily drives and adventures.

Interior Dimensions & Cargo Room: Q7 or GLS?

Both of these rivals come standard with seating for seven, but only the new Mercedes-Benz GLS SUV offers optional seating for six, allowing for a more comfortable drive for everyone inside. If you don’t think you’ll make much use of that last available seat, we’re sure that your passengers will appreciate the extra space! However, even if we compare the 7-passenger versions of the Q7 and the GLS, it’s clear that the GLS has the more practical interior:

2020 Audi Q7 Dimensions

  • 1st-Row Legroom – 41.7 inches
  • 2nd-Row Legroom – 38.8 inches
  • 3rd-Row Legroom – 29.2 inches
  • Cargo Volume (Minimum) – 14.2 cubic feet
  • Cargo Volume (Behind 2nd Row) – 35.7 cubic feet
  • Cargo Volume (Behind 1st Row) – 69.6 cubic feet

2020 Mercedes-Benz GLS Dimensions

  • 1st-Row Legroom – 40.3 inches
  • 2nd-Row Legroom – 41.9 inches
  • 3rd-Row Legroom – 34.6 inches
  • Cargo Volume (Minimum) – 17.4 cubic feet
  • Cargo Volume (Behind 2nd Row) – 42.7 cubic feet
  • Cargo Volume (Behind 1st Row): 84.7 cubic feet

Legroom and cargo space are two of the most important factors for SUV drivers near Ashburn and Leesburg, and the GLS SUV has both in spades!

Performance and Utility: Q7 or GLS?

GLS vs. Q7: Base Engines

  • The 2020 Mercedes-Benz GLS 450 comes standard with a 3.0L inline-6 turbo engine with EQ Boost, delivering 362 hp and 369 lb-ft of torque.
  • The baseline Audi Q7 2.0T Premium only offers a 2.0L I4 with 248 hp and 273 lb-ft of torque, but the two engines still get identical fuel economy estimates!
  • The GLS gets a 9G-TRONIC® 9-speed AT, while the Q7 gets an 8-speed AT. This means there’s really no contest at all between the base trims.

GLS vs. Q7: Engine Upgrades

The Audi Q7 SUV’s V6 engine is new-and-improved for 2020, but does it have what it takes to go head-to-head with the GLS?

  • If you do choose the more powerful engine for your Q7, you’ll still only be able to access 335 hp and 369 lb-ft of torque.
  • It’s a closer contest, but you’ll still burn more fuel than you would with a GLS.
  • If it’s power you’re after, upgrade with the GLS 580. You’ll receive a 4.0-liter turbo V8 with 483 horsepower and 516 pound-feet of torque.

Still not convinced? With the right equipment, the Mercedes-Benz GLS can tow up to 7,700 pounds. The Audi Q7, on the other hand, can only tow about 4,400 pounds! Which SUV would you rather have for your adventures in Fairfax and Centerville?
