Shape of Things to Come

| May 01, 2012

Peterbilt is taking 579 orders now, with the first production trucks likely to arrive at fleets and dealerships by late summer. The new truck is a fine addition to Peterbilt’s overall lineup and one that fuel conscious fleets and owner-operators will want to consider as fuel prices continue to rise. Peterbilt knows that aerodynamics and styling are not mutually exclusive factors when it comes to designing a dependable and productive truck.
