THE ENVIRONMENTAL Protection Agency's (EPA) SmartWay Program has recognized Peterbilt's Model 386 liquefied natural gas (LNG) truck as meeting the established fuel-saving, low-emission equipment requirements set for Class 8 trucks.
The Model 386 LNG will join Peterbilt's family of SmartWay-designated vehicles, which includes the Model 587, Model 386, and Model 384.
“Peterbilt is proud that the Model 386 LNG has been recognized as the industry's first alternative fueled vehicle to obtain SmartWay designation,” said Bill Jackson, Peterbilt general manager and PACCAR vice-president. “The Model 386 LNG SmartWay designated vehicle offers optimal fuel and emissions efficiency with horsepower and torque equal to a diesel-fueled engine, making it the ultimate environmentally sound performance solution for customers, and further demonstrates Peterbilt as an industry leader in developing innovative quality products.”
The alternative fueled vehicle is poweredby the EPA-certified Westport GX engine, offering up to 475 horsepower and 1,750 lb-ft of torque. The 15-liter engine uses high-pressure direct injection technology (HPDI), specialized cryogenic fuel tanks, and associated electronic components. This technology uses a lower cost, cleaner-burning fuel than diesel without compromising engine torque, power, fuel economy, or drivability, in addition to reducing greenhouse gas emissions by 25%.
The aerodynamic package for the SmartWay vehicle features roof fairings with trim tabs that help propel air up and over the cab and trailer, re-contoured chassis fairings with a “flair” design pushing airflow around the tires and wheels, and an exclusive Peterbilt transition fairing positioned between the cab and detachable sleeper directing airflow over and around the sleeper.
