In the autumn of 2006, the 7.1-liter engines of the Diamond and R8 models received common rail injection and 4-valve technology. A year later, the engines were further improved, among other things with a new intercooler, and torque figures were enhanced. Otherwise, the range remained almost unchanged. The transmissions, including creep gears, had 40+40 speeds. The quick shift was 4-speed, and range changes were also handled by the transmission automation.

The load-sensing hydraulic system had a capacity of 120 l/min, and four electrically controlled valve blocks were standard. The headland automation could be programmed with 16 functions. There were engageable 100% locking differentials at both front and rear. The front axle had hydraulic suspension. The cab suspension was pneumatic and equipped with level control. The turning circle diameter was reported as 13.5 meters.
