MAN first announced in late 2003 that the HX range of tactical trucks would replace the FX and lighter LX ranges. Four HX models have so far been detailed, although others will certainly follow.

The HX range is based on MAN'S latest TGA commercial driveline components and the chassis is fitted with the latest version of the modular military cab, which is also fitted to the SX range.

To achieve maximum commonality between the commercial and military products, revisions to the military version's TGA driveline involved relocating the HX's cooling pack to behind the cab. This enhances the vehicle's hot climate operating capability and enables certain models to fit the C-130 envelope. An applique armour kit has been developed for the cab.

The HX60 4x4 (six-tonne payload) mirrors the concept of the LX range. It is designed to be lighter and more mobile, both tactically and strategically and, as such, is air-portable in a C-130 Hercules with little preparation.

With minimal alterations, the HX60 meets the criteria for high mobility. It is possible an LX-mirroring light' 6x6 high-mobility chassis with independent rear-axle suspension could be introduced.

The heavier-duty high towing loads HX58 6x6, HX76 (8x8 tractor truck) and HX77 8 x 8 are air-portable on wide-body aircraft and are more closely related to the outgoing FX range.

Motive power for the HX60 is provided by a latest-generation MAN Common Rail small block diesel engine developing 326hp and 1,250Nm torque. The HX58 (nine-tonne payload) and HX77 (15-ton ne payload) have the option of latest-generation MAN Cormmon Rail diesel engines developing 430hp and 2,1 OONm torque or 480hp and 2,300Nm torque. The HX76 is powered by a V-10 diesel engine developing 700hp.

All HX models are fitted with a 12-speed ZF AS-Tronic automatic constant mesh gearbox and MAN two-speed transfer box. Driveline enhancements for the HX76 include a ZF torque converter. The latest 'single tyre specific' MAN hub-reduction drive axles sprung by leaf springs, with bogie-type suspension for the rear axles, complete the driveline.
