Mercedes-Benz popularized the luxury sport-utility class seven years ago with its first ML 320, its first product built in the U.S. since the early 1900s and its first consumer-oriented SUV, built to a price under $30,000. A lot of water has gone over the dam since then, and this brand new
M-Class has been completely re-engineered for a new generation of luxury SUV buyers.
Instead of the original body-on-frame truck-style design, this new one has welded unibody construction with isolated front and rear subframes, a technique that emphasizes high strength and low weight, and reduces the overall height, making it easier for families to get in and out of.
It's been re-proportioned, too. The wheelbase is almost four inches longer, the body almost six inches longer, and nearly three inches wider, all the better to accommodate larger American individuals and families, and an indication that the original was simply too small. In the bargain, the coefficient of drag or Cd number, has dropped from a bricklike 0.40 to a sylphlike 0.34, on a par with many passenger cars that are much lower to the ground. This means quieter highway ride and better fuel economy.
