Peterbilt Motors Company and Kenworth Truck Company unveiled new design enhancements for the their medium duty cabovers in the Class 6 and Class 7 markets. Peterbilt's models saved their indexes 210 and 220, while Kenworth's models received new names K270 and K370. The new 2012 designs have paired a lightweight chassis and frame rail with a strategically positioned electrical system to optimize body installation and increase payload capacity. The new models utilize Selective Catalytic Reduction (SCR) technology and are 2010 emissions compliant. In addition, the new designs are available with an Allison 2100 Series automatic transmission which helps provide a smooth, comfortable ride.
Both vehicles of each manufacture are powered by the reliable, lightweight PACCAR PX-6 with horsepower ratings of 220, 240 or 250 and torque ratings of 520, 560 and 660 lbs-ft, respectively. Ideal for medium duty truck owners, the fuel-efficient PX-6 provides an in-line 6 cylinder 6.7-litre devise with four valves per cylinder, a high pressure common rail fuel system and features the best power-to-weight ratio available in its class. New models are differed from the last generation only by a slight change of front grille.
“To expand versatility in Peterbilt’s medium duty line, and to capitalize on market growth, our team of engineers has developed new designs for the Model 210 and 220 to enhance driver productivity,” said Landon Sproull, Peterbilt chief engineer. “The 2012 designs offer optimal maneuverability, comfort and ease of operation, providing drivers an advantage while operating in congested environments.”
“We’re excited to bring Kenworth quality to the cabover market,” said Gary Moore, Kenworth general manager. “Kenworth’s new K270 and K370 cabovers offer excellent maneuverability, durability, styling and ease of service for customers operating in urban operations.”
