The production version of the MD-X concept we saw at the New York show last spring is cleaner and less snarly looking. These spy shots show a big brother to the new RDX, with a more expressive interior featuring motorcycle-style gauges. The second-gen MDX carries forth some of the 2001-2006 models' underpinnings, but with a longer wheelbase and wider track to provide a sportier look and feel. It's expected to get the RL's 290-horsepower, 3.5-liter V-6, with cylinder deactivation.
