BAE Systems and Caterpillar are teaming up to build parallel hybrid systems for heavy-duty trucks using BAE’s HybriDrive System.  The deal has BAE merging the Cat CX family of transmissions into their parallel HybriDrive propulsion system.  This will establish a sales outlet as well as aftermarket field services model to leverage the global reach of Caterpillar with the technology of BAE.

This diesel electric hybrid truck system will improve fuel economy up to 30% on most heavy-duty truck applications, including refuse collection, construction, pickup-delivery, and utility vehicles.  It is not expected to give significant economy improvements to highway-centric over-the-road (OTR) applications.

“Building upon our initial relationship to develop the parallel hybrid electric system, this supply agreement cements Caterpillar as a key supplier and partner on a system that will lower fuel and ownership costs and emissions for fleet owners,” said Steve Trichka, General Manager of BAE System’s HybriDrive Solutions.
