To meet different threat levels the Fuchs 2 has been designed to be fitted with enhanced passive armour packages developed by IBD.
To enhance survivability while conducting Military Operations in Urban Terrain (MOUT), Rheinmetall has developed a modular upgrade package for installation on tracked and wheeled armoured vehicles.
Continued development of the Fuchs 1 resulted in the Fuchs 2, the first example of which was shown in public for the first time at the 2001 MSPO in Poland.
Normal amphibious payload for Fuchs 1 is 4000 kg, but, depending on configuration and protection options, up to 5,000 kg of cargo can be carried on land. Motive power for the Fuchs 1 is provided by a Mercedes-Benz Model OM 402A V8 12.8-litre water-cooled diesel engine developing 320 hp, this coupled in a powerpack set-up to a six-speed planetary gear torque converter transmission.When closed up, the periscopes fitted in the roof of the vehicle to the front of the driver's hatch allow visibility out of the cabin. The troop/cargo compartment, which is at the rear of the vehicle, is 3.2 m long, 1.25 m high and 1.5 m wide at its widest point.On the Fuchs 2, the roof height has been raised by 145 mm for greater internal volume.The work was carried out between 2004-2007 at Kassel, where the vehicles were originally built.Vehicles upgraded under this contract were given the TPz A7 designation.
The latest upgraded Fuchs 1 are given the TPz A8 designation, deliveries of these first made to the German Army in March 2008.
