DAF has launched their new PACCAR Aero body as a factory fit option on the DAF LF at 7.5 to 12 tonnes GVW. The PACCAR Aero body is designed to be more streamlined than conventional bodies and has a moulded roof fairing and cab collars which are aerodynamically integrated with the LF cab, a curved front part of the body and rear tailgate air diffuser over the rear frame.
Using Computational Fluid Dynamics in its design, the PACCAR Aero body has been developed to reduce fuel consumption at cruising speed by up to 8% compared to a similar capacity conventional ‘square’ box body with a simple roof fairing.
The overall cubic capacity of the new Aero body is still more than 98% of a square box body of similar overall dimensions and, by taking advantage of the DAF LF’s low frame height, a rear aperture height of 2260mm is available within an overall laden vehicle height of 3560mm, even with the rear diffuser incorporated. The interior of the front bulkhead is designed to be the same size as the rear aperture, so that if the load will fit through the rear shutter, it can be stacked against the front bulkhead (or elsewhere in the body) which is important for taller load items such as ‘American’ style refrigerator deliveries.
The new Aero body sits along side DAF’s existing conventional box and curtain-sided bodies which are designed and built in the Leyland Trucks plant in Lancashire. The number of PACCAR factory built bodies now in use now total over 2,000. The PACCAR Aero body is available in a range of body lengths from 5150mm to 6810mm and is available at two overall widths of 2480mm or 2350mm, with a choice of roller shutter or double rear doors.
“We’ve deliberately designed our body to not only save fuel but also deliver maximum productivity for our customers”, said DAF’s Marketing Director Tony Pain. “Indeed we have researched and tested more extreme designs but they often compromised day-to-day practicalities of operation and load capacity. We believe the PACCAR Aero body is uniquely productive – just like the truck which goes underneath it”!
