Sterling has a press release announcing their new Natural Gas-Powered truck. It is powered by a Cummins Westport ISL G that is LNG or CNG capable. I’m only seeing horsepower ratings to 320 but they have a statement on their site that says the Westport LNG system is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque.
