The changes primarily affected the cabin design, its appearance became more aggressive and recognizable, while retaining elements of the recognizable Astra corporate identity. The cab of the truck was inherited from a cousin of the Iveco Trakker. Astra has introduced the new HD9 with a ROPS heat treated steel cab. The interior of the cabin itself has been completely changed, it is designed specifically for greater spaciousness and comfort. Passenger access has been improved, thanks to the ideal distance between the first two steps and the last one, as well as the double first handle on both sides of the door, and the doors themselves open 90o.
