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 Allision bus on display in Washington DC.
The sign on the side reads,
"Up to 90% reduction in emissions."
