Western Star introduced its new, aerodynamic 5700XE highway tractor at a press launch in Las Vegas Thursday.
The new truck features a highly sculpted, sleek design that retains the bold styling and robust stance of years past while delivering fuel economy numbers that place the truck firmly in the most aggressive Greenhouse Gas emissions regulation category.
The 5700XE can be spec’d with the DD13, DD15 or DD16 engine and comes standard with the Detroit DT12 automated manual transmission that can be mated to any of the Detroit engines offered.
