Sure it’s a tough job but someone’s got to do it and we’re up for the challenge. Enjoy this comparison of the 2018 Mercedes-Benz GLS vs 2019 Infiniti QX80. We’ll get started by approaching the performance of the Mercedes-Benz and the Infiniti side-by-side.

2018 Mercedes-Benz GLS vs. 2019 Infiniti QX80: Performance

The 2018 Mercedes-Benz GLS offers a choice of three powerful engines, each of which pairs with a smooth-shifting transmission. The GLS 450 comes with a twin-turbo 3.0-liter V6 engine that puts out 362 horsepower. You might think a big SUV needs a V8, but this V6 has plenty of power for most driving situations. You can step up to a V8 by opting for a higher trim. The V6 gets the best fuel economy of the group, but the two available V8s deliver outstanding power and acceleration. No matter which engine you choose, you’ll enjoy a smooth ride and, thanks to the GLS’ standard all-wheel drive, plenty of road grip. It’s poised around turns, and the ride quality – especially in Comfort mode – is terrific.

The 2019 Infiniti QX80 is no pushover on the road. It has a powerful V8 engine, a smooth transmission, and a comfortable ride. The QX80 has a 400-horsepower 5.6-liter V8 engine and a seven-speed automatic transmission. The automatic transmission makes smooth, timely shifts. Large SUVs are not renowned for their excellent fuel economy, and the QX80 is no exception. As expected from a luxury SUV, the QX80 glides over imperfections in the pavement. What’s not expected from a vehicle of this size is its nimble handling. The available Hydraulic Body Motion Control system boosts this SUV’s agility by helping limit its body lean around corners. It’s not a sedan, but this SUV isn’t as clunky as you’d expect.
