The Mercedes-Benz GLS-Class, formerly Mercedes-Benz GL-Class, is a full-size crossover luxury SUV produced by Mercedes-Benz since 2006. In each of its generations it is a three-row, seven-passenger vehicle positioned above the GLE-Class (formerly Mercedes-Benz M-Class before 2016).[1] The GLS-Class is considered the flagship of the marque's SUV lineup, although the body-on-frame G-Class (originally intended for military off-roading but also offered in luxurious trims) is more expensive and has been in production longer.
