Photos of the Allison Parallel Hybrid-Electric Bus

The Allison bus, quite frankly, surprised me. The encapsulation of the two electric motors in the transmission, and using them to start the diesel engine, drive the bus at slow speed, and control the speed and torgue transfer of the vehicle is quite sophisticated.

The sign on the side reads, "Up to 90% reduction in emissions."
