The signature Acura grille forms the centerpiece for the tapered front end. The MDX's angular headlights house projection-type beams. An aerodynamic chin spoiler integrated into the front bumper directs air smoothly to the sides of the car. The rear end sports large taillights and dual exhaust tips.
In other words, the MDX still looks like an MDX. Limited overhang at either end contributes to a dense, compact demeanor that belies this SUV's heft and somewhat exaggerates the size of the MDX's mid-section. Some believe the large greenhouse adds to the straightforward sense and strong presence. Others claim it makes the MDX seem more like a minivan than a big SUV. We say, both.
What's most interesting, and isn't obvious except in a body-off view, is the duality of construction under the MDX. It is both unibody and body on frame. This approach gives uncommon rigidity and strength gained from longitudinal rails with eight box-section cross members. It's the thinking engineers' path to making a car/truck both a car AND a truck, whichever is appropriate to the occasion. The hoped-for effect is noise, vibration and harshness control on par with a car and load and stress management characteristic of a truck. Within the MDX frame, there's even a vent tube that wicks moisture away from the differential when the vehicle is sitting in 18 inches of water.
Two safety points: The 2006 MDX achieved a five-star federal crash rating for front impacts and side impacts (the best, indicating a 10 percent or less chance and a 5 percent or less chance of serious injury, respectively) and a four-star in rollover (next to best, indicating a rollover risk of between 10 percent and 20 percent). The company also claims its SUV can be hit from behind by a vehicle going 35 mph without the third row of seats being breached. The MDX's comparatively high fuel economy ratings are a testimony to the efficiency of its design and engine technology, and all models sold nationwide meet the government's strict ULEV-2 emissions standards (Ultra Low Emissions Vehicle).
