After an all-new look for 2006, the 2007 M-Class adds the ML320 CDI diesel and high-performance ML63 AMG to its lineup. The diesel-powered ML320 CDI boasts 215-horsepower and 398 lb-ft of torque and can travel over 600 miles at highway speeds on one tank of fuel according to Mercedes. The ML63 AMG sports an athletic design with bolder front and rear aprons, an AMG front grille, flared fenders, AMG side skirts, tinted taillights, and two sets of chromed twin exhaust pipes. The interior is fitted with AMG sport seats, a leather AMG sport steering wheel, special instrument cluster with AMG graphics, AMG door sills, leather wrapped dashboard, and stainless steel pedals with rubber studs. Power comes from a 6.3-liter naturally aspirated V8 engine that produces 503 horsepower and 465 lb-ft of torque with zero to 60 mph track times in less than five seconds.
