As the Fuel efficiency Face-off winds down, Fleet Equipment’s Jason Morgan and I-Torque super spec’er Joel Morrow make their way up through the hills of Fancy Gap, Virginia – behind the wheels of two very different Volvo trucks. While Jason enjoys relative ease behind the wheel of Joel’s Purple Haze, Joel finds himself making mental calculations on the fly to track his fuel efficiency numbers. The crowning of our Fuel Efficiency Face-off champion has arrived. Who will win?
