Allison Transmission has invested in a non-controlling equity stake in Odyne Systems LLC, which designed and developed a plug-in hybrid power system that interfaces with the Allison family of commercial vehicle transmissions.

The new relationship between Allison and Odyne will directly benefit hybrid vehicle operators in vocations such as utility bucket trucks, digger derricks, cranes and other applications that require worksite stationary power, according to the company.

Allison Transmission has been producing hybrid-propulsion technology since the early 1990s. During that time, Allison developed hybrid propulsion systems for city buses which went into production in 2003. By the end of 2011, city buses equipped with the Allison H 40/50 EP hybrid system were operating in 230 cities worldwide. It has been estimated that these vehicles have saved more than 26 million gallons of diesel fuel and prevented more than 259 metric tons of carbon dioxide from being emitted into the atmosphere.
