DENTON, Texas --- Peterbilt Motors Co. delivered its first medium-duty hybrid vehicles into the market in August to McCoy's Building Supply. Peterbilt made the announcement during a press conference at the 2007 Great American Trucking Show. Two Model 335 hybrid electric vehicles were introduced into McCoy's fleet of delivery trucks used to deliver lumber and other supplies throughout the greater San Antonio, Texas, area. "Peterbilt is proud to be at the forefront in the development and production of green technologies that not only help save the environment, but contribute to our customers' bottom line by providing greater fuel savings and reduced maintenance costs," said Bill Jackson, Peterbilt general manager and PACCAR vice president. "We support responsible environmental management practices that result in long-term economic and environmental benefits," said Art Johnson, McCoy's vice president of store development and asset management. The hybrid electric Model 335 uses an electric motor that works with the mechanical diesel engine to supply supplemental torque. The system stores energy during stopping through regenerative braking and then reuses it for acceleration. During typical stationary operation of the PTO, the engine needs to run only about one-sixth of the time versus non-hybrid vehicles. The engine automatically starts when batteries require recharging, which takes approximately 4.5 minutes. Fuel use, emissions and noise are greatly reduced. Maintenance requirements are also reduced from less wear on the engine and the brakes. "While our hybrid trucks have just been put into our daily operations, we anticipate receiving a 30-35 percent savings in fuel costs in addition to the reduction in maintenance costs," Johnson said. McCoy's Building Supply, headquartered in San Marcos, Texas, has 86 stores and two manufacturing facilities located throughout five states. The company has 350 trucks in its fleet.
