Because it's a gas, the fuel tank of a vehicle running compressed natural gas is that bit thicker and stronger. In the United States of America there hasn't been any natural gas vehicle fuel tank rupture in more than 2 years. So what kind of bits and bobs make up the Volvo FE CNG medium duty truck? Firstly, there's an all-new 9-liter engine featuring spark plug technology, which is mated to a six-speed automatic. Although it was designed to run as green as possible, the mill packs 320 horses and 1,356 Nm of torque.
“Spark plug technology is particularly suitable for driving cycles where the truck covers short distances with a lot of start-stop traffic,” declared Christina Eriksson, Volvo Trucks' alternative drivelines business manager. “With the Volvo FE CNG we can now offer companies that drive predominantly in urban environments a truck with a far lower environmental impact. Many cities the world over are looking for alternatives to diesel-powered trucks. In the field of refuse handling, for example, renewable fuels are often a requirement for securing a contract.”
