Mercedes-Benz has begun demonstrating its new Citaro G BlueTec hybrid bus with what is claimed to be the world's largest lithium ion battery pack application. The new Citaro G is an 18-meter articulated bus with a series hybrid drive system. A smaller 4.8-liter diesel engine replaces the typical 12-liter engine used in such applications and drives a generator which provides electricity to hub motors mounted at the center and rear axles. The 771 lb lithium battery pack provides 180 kW and is charged both from the generator and from the regenerative braking. The bus can operate for short distances on battery power alone and reduces diesel fuel use and CO2 emissions by a estimated 30 percent compared to a standard bus of this size.
