Comparing the 2017 Mercedes-Benz GLS 450 against the 2017 Lexus GX demonstrates just how great the difference can be between a front-line model and one that barely makes the luxury grade. The three-pointed Star of Mercedes-Benz acts as a hallmark of precise craftsmanship and an unflagging obligation to push the industry further. When you match the GLS 450 against the GX, you can see just how a dedicated luxury manufacturer is distinguished from one with its roots in the standard segment.

Power and Efficiency

2017 Mercedes-Benz GLS450The vast distances that separate the 2017 Mercedes-Benz GLS 450 from entry-level competitors like the 2017 Lexus GX becomes obvious when you compare their performance and efficiency specs.

The 2017 Lexus GX has stuck with the common formula, fitting each model with a 4.6L V8 engine that provides up to 301 horsepower. This V8’s power might sound impressive, but Mercedes-Benz innovated beyond the need for eight cylinders with their 3.0L bi-turbo V6, which delivers V8-level power without the associated fuel consumption. In fact, performance upgrades, such as rapid-multispark ignition and high-pressure Direct Injection, make the GLS 450 SUV’s V6 even more forceful than the GX’s V8, coming in at a striking 362 horsepower.

That power is refined by a new 9-speed automatic transmission that shifts almost instantly, resulting in a quiet, soothing, and seamless ride, plus the ability to earn up to 17 mpg in the city and 22 on the highway. The Lexus GX retains an antiquated six-speed; that might be fine for a run-of-the-mill Toyota, but its jerkier drive and maximum 15 mpg city/20 mpg highway ratings make it less appealing next to the clean-burning sophistication of the 2017 Mercedes-Benz GLS 450.


Boasting up to 93.8 cubic feet of storage room vs. a mere 64.7 in the Lexus GX, the GLS 450 will impress you with its generous interior. However, the first thing to strike you is likely to be the incredible array of exclusive technologies on offer, including:

  • COMAND® with Optional Touchpad Controller: Enjoy intuitive access to infotainment and connectivity systems though a touchpad that responds to a variety of finger motions.
  • Optional Bang & Olufsen® BeoSound Premium Sound System: Uses 14 active speakers with two Acoustic Lenses and 900 total watts of power to develop an immersive surround-sound experience.
  • Optional In-Car WiFi Hotspot: Provides a stronger and more stable connection to the internet than your smartphone, and without digging into your data plan.
