Why RENK’s 800 kW powerpack is the quiet star of Eurosatory

With the 800 kW powerpack, RENK Group AG rolls a chunky, self-contained heart for future tanks onto the Eurosatory floor, all hoses, radiators and gearbox tucked into a surprisingly compact block. You can almost feel the torque waiting under the exhibition hall lights.

What RENK is showing in Paris

The new 800 kW powerpack is RENK’s answer to heavier armor, active protection systems and more electrical loads in modern tracked vehicles, all of which demand significantly more drive power in roughly the same engine bay.

The module combines diesel engine, automatic transmission, cooling system and auxiliary units in one swap-ready package, so mechanics can pull the entire drive out of a tank’s rear within hours instead of days.

Compact muscle for heavy tracked vehicles

RENK targets vehicles in the 50 to 70 ton range with the 800 kW class, from main battle tanks to heavy infantry fighting vehicles that outgrew legacy drivetrains years ago.

Compared with older 1,000 hp powerpacks, the new unit promises higher specific output and better packaging density, freeing room for fuel, batteries or additional electronics without stretching the hull.

Why the power density matters

On the battlefield, more power is not just about top speed. It is about how fast a 60 ton vehicle can pivot, reverse out of cover or climb a muddy embankment without bogging down and exposing its side armor.

The 800 kW output gives commanders extra margin for last-second maneuvers and for keeping speed even as add-on armor, cages or electronic warfare kits add unexpected weight over a vehicle’s life.

Maintenance, logistics, and noise

Because everything is integrated, the powerpack can be pre-tested as a unit at the depot, reducing unpleasant surprises after field installation and making spare modules a tradable asset within alliances.

RENK also talks up improved efficiency and reduced acoustic signature, both crucial when thermal and acoustic sensors are hunting vehicles long before first contact.

Link to RENK’s UGV and hybrid ambitions

The 800 kW powerpack does not stand alone. At Eurosatory, RENK is also visible with Patria on a heavy unmanned ground vehicle concept that uses RENK’s TrackX running gear and HSWL 076 transmission for autonomous operations.

Together, the compact manned-vehicle powerpack and the UGV drivetrain show a company that wants to sell the complete motion chain, from classical tracked tanks to robotic platforms roaming ahead of manned formations.

Where the market pressure comes in

Despite the strong technical story, commentators at the show note that investors now look less at concepts and more at signed multi-year programs, especially as several European armies plan large recapitalization cycles.

RENK’s 800 kW module therefore needs to win integration slots in concrete platforms, whether in upgrades of existing fleets or in future projects such as joint European main battle tank initiatives.

Company context and stock reference
