Electric Power Train on a Bus 160km Range

This would make me take the bus if it was my only alternative:

City buses traveling a total of 210 km per day will have an effective fuel economy of 4.7 liters per 100 km, or 50 miles per gallon. MESA should be an Olympic triple jump past the 47L/100 km (5 mpg) performance of traditional diesel buses. That translates to an estimated annual reduction in greenhouse-gas emissions of 4250 metric tons per bus, or 5.5 billion tons per year if all of China’s 1.3 million diesel buses were replaced with MESA power trains.
