All-new last year, the MDX returns unchanged for 2015. Under its hood, we still find a 290-hp 3.5L V6 with active cylinder management attached to a classic six-speed automatic gearbox. The 267 lbs.-ft. of torque is sent to all four wheels through Acura’s SH-AWD system. While the base version is already very well equipped, technology aficionados can opt for the Navi, Tech or Elite versions of this seven-seater for even more content.
