HybriDrive® Series – The world's most successful series
hybrid electric propulsion system for transit bus.
Hybrid City Bus
At BAE Systems we are proud to be part of the effort to keep our environment safer and greener. Our HybriDrive® Series powers the world’s largest hybrid bus fleet and carries over 3 million passengers every day. Our systems have traveled over 500 million miles, prevented over 460,000 tons of CO2 emissions and saved over 30 million gallons of diesel fuel.
The series design is optimized for city bus duty cycles that typically have low average speeds and frequent stops. In this type of environment, series provides better bus fuel economy and emission reductions than a parallel solution. Our HybriDrive® Series solution for hybrid buses also offers the only true path to an all Electric Vehicle (EV).
The successful HybriDrive® Series system for hybrid buses is available on more OEMs and fleets than ever before and our offerings continues to grow.
Hybrid Electric Solution for Articulated Buses
The new HybriDrive® Propulsion System for Articulated Buses is a powerful hybrid bus solution able to drive vehicles up to 63,000 pounds. It provides superior acceleration, making it easy to climb steep hills, and sustains a top speed of 65mph. And, most importantly, it meets or exceeds APTA guidelines for sustainability.

Why HybriDrive®?
Independent measurements have shown that HybriDrive® consistently provides the greatest energy savings in city bus propulsion tests. Our integrated hybrid power systems also maximize your operational budget due to their superior efficiency and impressively low maintenance costs, making HybriDrive® the best hybrid solution. Altoona Bus Research and Testing Center study results show that HybriDrive® bus fuel economy is noticeably better than alternative electric drive propulsion systems, making HybriDrive® the best source of hybrid electric savings.
A comprehensive test conducted at the Altoona Bus Research and Testing Center in Pennsylvania showed that in some cases HybriDrive® hybrid buses achieved almost double the MPG of equivalent conventional diesel buses.
The hybrid electric motor offers a smooth, powerful, shift-free ride that your passengers will really appreciate. See what real people have to say about hybrid electric buses:
