Fresh styling, more power, and new features highlight the 2007 redesign of Acura's premium midsize SUV. MDX gains 2 inches in wheelbase and overall length vs. the 2001-06 model, but keeps seven-passenger seating. MDX retains a V6 as its only engine, but a new 300-hp 3.7-liter version replaces a 253-hp 3.5. The sole transmission remains a 5-speed automatic. New and standard for '07 is Acura's Super-Handling All-Wheel Drive (SH-AWD), which does not include low-range gearing but apportions power between the rear wheels to enhance cornering ability. ABS and antiskid control are also standard. So are front side airbags and curtain side airbags that cover all three seating rows and include rollover deployment. Other standard features: sunroof, leather upholstery, heated front seats, and wireless cell phone link
