Great track record: At Eurosatory 2026, ZF highlights expanded portfolio for tracked vehicles
- World premiere: ZF unveils the new LSG 4000 powershift steering transmission
- Electrification milestone: eLSG 5000 reinforces ZF’s future-ready driveline strategy for defense applications
- Proven expertise in transmissions for tracked vehicles from 3 to 60 tons vehicle weight
Friedrichshafen, Germany/Paris, France. At Eurosatory 2026, ZF will present its expanded portfolio of driveline solutions for tracked vehicles. The centerpiece of ZF’s exhibition appearance is the world premiere of the new LSG 4000 powershift steering transmission, being developed for heavy tracked vehicles weighing up to 70 tons. Also on show will be the eLSG 5000, ZF’s electrified powershift steering transmission, underscoring the company’s ability to combine proven mechanical expertise with forward-looking electrification concepts. ZF will exhibit in Hall 6, Booth G379 at Eurosatory 2026 in Paris from June 15–19.
Immense weight. Massive Torque. Harsh Terrain. Tracked defense vehicles are built to withstand heavy stress during deployment. This, of course, puts substantial stress on their systems and components. “These types of platforms face incredible challenges on missions,” explains Ralf Boss, Head of the Special Vehicle Systems Product Line at ZF. “The driveline shouldn’t be one of them.”
That’s why at Eurosatory 2026 – and true to its “Together on Mission” slogan – ZF emphasizes its position as a long-standing and reliable partner to the defense industry. While the company is particularly well established in wheeled vehicle solutions, ZF also draws on decades of experience in tracked vehicle mobility. Its portfolio reflects deep system expertise, proven technologies and extensive application know-how.
ZF premiers the all-new LSG 4000
A special highlight is the LSG 4000, a new generation of powershift steering transmissions for heavy tracked vehicles up to 70 tons. A core element of the LSG 4000 is its efficient drive and cooling concept, which contributes to optimized overall efficiency. The transmission system, with integrated steering and braking, is fully controlled by-wire, opening up entirely new possibilities in vehicle design, user interaction, remote operation, and autonomous capabilities. Additionally, it features an integrated retarder, which enables high, wear-free braking performance and supports safe vehicle operation under demanding conditions.
This state-of-the-art control concept enables smooth shifting, precise steering behavior and high driving comfort. The LSG 4000 uses mechanical radius steering, providing an efficient, proven solution, with a clear path toward near-stepless steering enabled by a future electronic control concept.
The LSG 4000 also focuses on maintenance-friendly design and lifecycle efficiency. While maintenance intervals are generally defined by the engine, the transmission itself requires minimal maintenance effort thanks to a simplified maintenance concept and modular architecture. Service-relevant components are accessible from the outside, reducing maintenance time and vehicle downtime.
eLSG 5000: Electrified steering transmission for future drive architectures
At Eurosatory, ZF also shows the eLSG 5000, an electrified steering transmission for heavy tracked vehicles, which marks a significant step toward next-generation defense mobility. By integrating electrification directly into the powershift steering transmission, the eLSG 5000 enables future operational concepts, including hybrid drive systems and further electrified subsystems. The system furthermore enables silent mobility and supports a significant reduction in acoustic and thermal signatures – both critical factors for modern defense operations. At the same time, electrification allows for highly efficient energy management, supporting increasingly electrified vehicle architecture and onboard power demands.
From a system perspective, the eLSG 5000 is designed to deliver high maneuverability and precise steering behavior under demanding operating conditions, partly due to its complete by-wire functionality (driving, steering and breaking). Its architecture supports seamless superimposition of steering input, contributing to smooth vehicle handling and enhanced agility. The system is engineered for robustness, scalability and integration, enabling use across different heavy tracked vehicle platforms and mission profiles.
Proven portfolio in defense drivelines
ZF’s current portfolio builds on established solutions such as the LSG 1100 (for vehicles up to 27 tons), which have been in the market for many years. This heritage underscores ZF’s long-standing expertise in tracked vehicle technology and provides a solid foundation for the latest generation of driveline systems.
ZF will demonstrate its future-ready mobility and digital solutions for the defense sector at Eurosatory 2026 (Hall 6, Booth G379) in Paris from June 15 to 19. In addition, the new mtu hybrid drive system featuring ZF’s eLSG 5000 will be unveiled on Monday, June 15, at 1:00 p.m. at the Rolls-Royce Power Systems booth J335 in Hall 6.
