The new Acura MDX offers a quiet ride and brisk acceleration performance. With the five-speed automatic, the MDX is rated to tow up to 5000 pounds.The 2007 Acura MDX benefits from a completely new platform, suspension, and unit-construction body with a built-in frame and subframes front and rear. The MDX is really stout, some 15 percent stronger in torsional bending and seven percent stronger in lateral bending. This time out, it has 56 percent of its body in high-strength steel as opposed to the original MDX's 13-percent HSLA steel content. It's longer and wider, with a 2.5-inch longer wheelbase and similar gain in overall length.
All that adds up to a quieter ride quality, with zero squeaks, creaks, groans or rattles.
The 300-hp 3.7-liter V6 engine is all-new for this application. Compared to the old 3.5-liter, it has been treated to a hot-rod upgrade, with a bigger bore, bigger stroke, higher compression (11:1, necessitating the use of premium unleaded fuel), and a higher redline (maximum rpm). It makes 47 more horsepower and 25 additional pound-feet of torque compared to the old engine. Acura says it's the most powerful V6 engine in any SUV sold in the U.S. market. It's quick, fast, and quiet, like every Acura engine before it, only more so.
