The Environmental Protection Agency has recognized Peterbilt's Model 386 liquefied natural gas (LNG) truck as its first SmartWay-designated alternative fuel vehicle, according to the company.

The Model 386 LNG will join Peterbilt's family of SmartWay designated vehicles which includes the Model 587, Model 386 and Model 384.

Equipped with a fuel-efficient, aerodynamic package, the Model 386 LNG SmartWay designated vehicle is ideally suited for a variety of applications, including line, bulk and tanker hauling.

The alternative fueled vehicle is powered by the EPA-certified Westport GX engine, offering up to 475 horsepower and 1,750 pounds-feet of torque. The 15-liter engine uses high pressure direct injection technology (HPDI), specialized cryogenic fuel tanks, and associated electronic components to facilitate robust performance and reliable operation. This technology uses a low cost, cleaner-burning fuel than diesel without compromising engine torque, power, fuel economy, or drivability, in addition to reducing greenhouse gas emissions by 25%.

"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."

Peterbilt offers a full range of compressed natural gas (CNG) and liquefied natural gas (LNG) power platforms.
