This is the first commercially viable hybrid bus that should see the market place by 2010. Using a combo diesel and lithium ion battery the 7700 Hybrid decreases CO2 emissions by 30%, doesn’t idle at lights and stops, reduces particle and nitrous oxide emissions by 40-50%, carries more passengers, and runs quieter than its fully diesel counterpart.
The cost for the 7700 Hybrid could add to profits for fuel savings over its diesel version after 5-7 years of operation. With the addition of the batteries, which are extremely heavy, the hybrid weighs only 100kg more and can accommodate an extra 7 passengers. The batteries are recharged by the energy created while braking and the resistance can be so strong it stops the bus itself.
When the 7700 is at stops or idle the engine is off and when it’s time to start the electric motor almost silently accelerates the bus to 25-30mph before the diesel takes over. This means less noise and pollution for passengers and bystanders.
The 7700 also has some comparatively sleek and sweeping design lines as well.
