Audi Q7 vs. Mercedes-Benz GLS: Performance Specs 

While the Mercedes-Benz GLS is offered at a higher starting price than the Audi Q7, it compensates with a more powerful engine. The Audi Q7 has two engine options to choose from–a standard 2.0L four-cylinder and a 3.0L V6 hybrid–but the Mercedes-Benz GLS outmatches both of them with its 3.0L six-cylinder hybrid engine. The GLS also offers a more powerful nine-speed automatic transmission and a much faster acceleration time than the Audi Q7’s standard engine, and gets better fuel economy than the Q7’s upgraded engine. Here are the full performance specs for both models:
