If you're going to build another luxury SUV, you may as well build one like the R-Class - an intriguing vehicle that has a free flowing and spacious interior design. Combined with two very capable engines - the 268-horsepower V6 for the R350 and a 302-horsepower 5.0-liter V8 for the R500, Mercedes should have no trouble selling their allotment in the United States. Ultimately, the 2006 Mercedes-Benz R-Class will do what every luxury crossover is intended to do: make rich people feel comfortable AND powerful, on their way to the store, work, or the country club.
