Diesel drive system from MTU

Together with the compact 10V 890 engine, the MTU drive system for Puma includes a six-speed transmission unit, a starter-generator, and an air cooling and filtering plant.

The German Armed Forces spent two years driving around and testing the prototype of a new armored tank, the Puma, before finally getting word that the Budget Committee of the German Bundestag had decided to procure 405 of the vehicles.

Propelling the tanks will be a drive system from Tognum’s MTU Friedrichshafen. The engine for the system will be based on MTU’s Series 890 engines, specifically the 10V 890 engines that are offered with a power output of 800 kW (1072 hp). The 890 engines are a modular family of diesel engines that range from four to 12 cylinders. It is a fourth-generation combat vehicle engine that evolved from applications in the Leopard I and II tanks and culminated in the U.S. Marine Corps Expeditionary Fighting Vehicle currently slated for deployment in 2015. The four-stroke engines range from 300 to 1100 kW (400 to 1475 hp). MTU claims that compared to other compact military diesel engines, the 890 diesels have 50% the volume and weight as other current diesels with an equivalent power range.

MTU’s drive system will consist of the 10V 890 being mated to a newly developed six-speed transmission from Renk and a starter-generator developed jointly with ESW.

By this August, the entire vehicle is to undergo final tests. The full order for the delivery of 405 drive systems could be placed by the end of 2008. The order volume will probably amount to €350 million and delivery will start in 2010. The armored carrier will be built by PSM Projekt System & Management, a joint venture between the German defense technology companies Rheinmetall-Landsysteme and Krauss-Maffei Wegmann.
