The Gepanzerter Mannschaftstransportwagen Kätzchen was a German armoured personnel carrier of late World War II. Auto-Union delivered two prototypes during 1944-45. The hull's shape was similar to the hull of the Panzerkampfwagen Tiger II, but much smaller. The vehicle had front wheel drive with five or six overlapping steel road wheels, possibly resembling the never-built E-25 "replacement tank"'s suspension system in appearance. Power was provided by a Maybach HL50 engine.
