Allison Transmission reached a milestone in its manufacturing of bus and coach hybrids by producing its 5,000th H 40/50 EP system. Since 2001, Allison says that since 2001, its hybrid-equipped buses have accumulated an estimated 389 million in-service miles.
“We believe that proves the reliability, durability and performance of our H 40/50 EP system,” says Lawrence Dewey, chairman and chief executive officer. “The build of our 5,000th H 40/50 EP is a major milestone for our company and the industry. Certainly, it is a tribute to everyone at Allison who has contributed to the success of this important program.”
Allison currently is developing another family of hybrid products, the first of which is the H 3000, targeted for trucks and other medium-duty commercial applications; production will begin in 2013. The second member of this family of hybrid products, the H 4000, is expected to be available in 2014.
