Sources & notes

This record describes the stated 2018 U.S. GLS 450 4MATIC configuration only, not every model year or trim in the generation.
Body dimensions use factory-published inches converted to millimeters; width excludes mirrors.
Fuel economy uses the current EPA vehicle record for the exact model year and drivetrain. EPA’s broad 4-Wheel Drive category is displayed as AWD when the manufacturer specifies 4MATIC all-wheel drive.
The X166 generation began as the U.S. GL in model year 2013 and continued under the GLS name after its facelift. The rename does not create a new generation.
