Fuel Economy, 7.1 Interior Noise Tests and 7.2 Exterior Noise Tests.  Testing started on June 14, 2006 and was completed on June 23, 2006. The Check-In section of the report provides a description of the bus and specifies its major components.

The interior of the bus is configured with seating for 40 passengers including the driver. Free floor space will accommodate 40 standing passengers resulting in a potential load of 80 persons. At 150 lbs per person, this load results in a measured gross vehicle weight of 40,780 lbs.
