This AMG SUV will have you saying OMG ASAP, thanks to the 577 hp from its twin-turbo 5.5-liter V-8. That power routes through a seven-speed automatic to a rear-biased AMG Performance all-wheel-drive system. The roomy cabin has space for seven in three rows of seating and coddles them with leather and wood trim throughout. Standard safety tech includes collision-prevention assist, crosswind assist, and brake assist; options include active lane keep, active cruise control, and blind-spot assist.
