The Mercedes-Benz Maybach GLS 600 4MATIC is a very luxurious variant of the X167 GLS-Class that debuted for the 2021 model year. It is powered by Mercedes' M177 4.0L engine and a 48V MILD Hybrid EQ Boost electric motor, which generate a combined 624hp. This powerplant is paired to a 9-speed 9G-Tronic automatic transmission that sends power to all four wheels. These cars are focused on luxury, with the Maybach branding helping indicate this.
