The interior follows a similar vein, with the top of the dash, the tops of the door panels and the roof being upholstered in black leather and Alcantara, while the rest is upholstered in green leather with diamond stitching. Technically, the Mercedes-Maybach GLS 600 4Matic has not changed, retaining the standard 550-horsepower 4.0-liter V8 petrol engine, combined with a 21-horsepower EQ Boost starter-generator, 9-speed automatic transmission and all-wheel drive.
