MISER Hydraulic Hybrid Transmission

A hydraulic hybrid transmission solution to regenerative braking and engine optimization for any size vehicle


The MISER hydraulic hybrid transmission significantly lowers fuel consumption (up to 43%) and reduces harmful emissions (up to 40%).

It is a fully automatic transmission that achieves fuel savings and reduced emissions by optimizing engine performance and regenerative braking. It is ideal for new vehicle designs where the engine can be chosen but can also be fitted to existing vehicles. The MISER design is a mechanically straightforward, infinitely variable dual path system with a relatively complicated microprocessor control system. The hydraulic hybrid transmission has fewer energy flow paths, fewer valves and fewer parasitic losses (e.g. charge pumps) than existing hydraulic hybrid systems. The MISER transmission is both a series (meaning the combustion engine can charge the storage system to use the energy later) and a parallel system (where the energy is decided to AND from any combination of the combustion engine, the storage system and the load).
