The German Federal Office for Defence Procurement (BAAINBw) has entered a new phase in the Main Ground Combat System (MGCS) project, which is intended to replace the current Leopard 2 and Leclerc tanks. One of the key advancements in this phase is the MGCS Power Pack, which will be developed by Rolls-Royce Power Systems as the main contractor, with ZF as a subcontractor. In addition, the two companies have begun working on developing the world’s first parallel hybrid drive system for heavy tracked platforms.
Next-Generation Power Unit: mtu Series 199
At the heart of the system is a new 10-cylinder engine developed based on the mtu Series 199 platform. This engine produces approximately 1,100 kW of mechanical power and serves as the primary source of the hybrid powerpack’s total output of over 1,400 kW. With multi-fuel capability and high power density, the engine integrates modern electronics to meet field requirements. In particular, its durable injection system, capable of running on low-quality fuels, provides operational flexibility.
Drivetrain and ZF eLSG 5000
The MGCS will feature the ZF-manufactured eLSG 5000 electric powershift steering transmission. This unit, with a continuously variable power layering system, combines by-wire technologies for driving, braking, and steering, while offering energy recovery (regeneration) capabilities. An integrated generator provides high-voltage electricity for the “silent watch” mode, and the new fan drive concept reduces energy losses, thereby extending the vehicle’s range.
Thermal Management and Operational Timeline
The hybridized cooling system, integrated with the adaptively controlled engine, increases overall efficiency while its compact design offers weight advantages and maneuverability within the vehicle. Under the MGCS project, the first prototypes of the powerpack are planned to be tested by the end of this decade, with serial production expected to begin in the early 2030s.
