Audi Q7 vs. Mercedes-Benz GLS: Engine and Performance

Neither of these German SUVs will disappoint on the roads near Weston or Trumble, but but the GLS is the cleaner winner on performance: Audi Q7

  • The standard 2.0-liter turbocharged engine gets you 248 horsepower
  • If you want more power, you can upgrade with a 3.0-liter six-cylinder engine that gets you a 335 horsepower
  • Although the Audi Q7 can tow up to 7,700 pounds with the right equipment, you’ll need to pay extra for a trim upgrade.
  • This model only comes with an 8-speed automatic transmission.

Mercedes-Benz GLS

  •  A 3.0L biturbo V6 engine is standard on the GLS 450 4MATIC®. With it, you’ll enjoy 362-hp. Even if you opt to upgrade the Q7 with its optional V6, you won’t have that much power.
  • All you need to do to reach the 7,700-pounds towing maximum is equip the optional trailer hitch!
  • With the GLS, you’ll receive the well-loved 9G-TRONIC® 9-speed automatic transmission.

Audi Q7 vs. Mercedes-Benz GLS: Cargo and Passenger Space

Drivers searching for the perfect SUV typically search for a vehicle that can accommodate friends and family and their belongings while still keeping everyone comfortable. Both luxury SUVs are able to seat seven passengers, but the GLS provides more overall space. In terms of passenger comfort and cargo space, the GLS outshines the Q7: 2020 Audi Q7

  • Cargo Volume (seats up): 14.2 cubic feet
  • Cargo Volume (seats down): 69.6 cubic feet
  • Front Headroom: 39.9 inches
  • Rear Headroom: 35.9 inches

2020 Mercedes-Benz GLS

  • Cargo Volume (seats up): 17.4 cubic feet
  • Cargo Volume (seats down): 84.7 cubic feet
  • Front Headroom: 39.4 inches
  • Rear Headroom: 40.2 inches

Despite the Audi Q7 squeaking ahead in front headroom, the rear headroom and spacious cargo space of the Mercedes-Benz GLS SUV make it very competitive.
