2017 Mercedes GLS450 GLS550 Review

Benz calls the GLS the S-class among SUVs, and with its rich appointments and power, who can argue? The three rows of seats have room for seven; the interior has leather, wood, and options like an air ionization system. The GLS450 has a 362-hp twin-turbo V-6; the GLS550 has a 449-hp twin-turbo V-8. Both have all-wheel drive and a nine-speed automatic. Safety tech includes cross-wind assist, collision-prevention assist, and brake assist.
