HMPT Series Transmissions

The HMPT 800 delivers exceptional performance in with industry-leading power density while retaining the same envelope and interfaces as the HMPT 500 Series. This lightweight package enables maneuverability and agility that will be needed for system survivability on the battlefields of the future.

This transmission has been in production in Korea (K21) since 2009 and in the United States since 2014 with Bradley Fighting Vehicle Systems (BFVS), Paladin Integrated Management (PIM), Armored Multi-Purpose Vehicle (AMPV) and Multiple Launch Rocket System (MLRS).

RENK America is currently in development on an upgrade to the HMPT, known as Project Wolverine. Wolverine is designed for 1,000 HP and retain the same interfaces as the HMPT 800.

The upgrade will drive improved dash speed, efficiency, and reliable operation at 50 tons. Wolverine adds Drive-by-Wire and High Speed Reverse to meet the requirements of new vehicles, while still maintaining the cost and logistics benefits of the HMPT in the current fleet.
