Molly Corporation submitted a model MB55 Freightliner Molly Trolley, propane-powered 31 seat (including the driver) 30-foot bus, for a partial STURAA test in the 10- yr/350,000 mile category. The Federal Transit Administration determined that the following tests would be performed: 4. Performance, 6. Fuel economy, 7.1 Interior Noise Tests and 7.2 Exterior Noise Tests. The odometer reading at the time of delivery was 1.7 miles. Testing started on July 17, 2006 and was completed on July 27, 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 31 passengers including the driver. Free floor space will accommodate 16 standing passengers resulting in a potential load of 47 persons. At 150 lbs per person, this load results in a measured gross vehicle weight of 23,800 lbs. In order to avoid exceeding the GAWR (8,000 lbs) of the front axle, ballast for all 16 standing passengers and 4 front seated passengers was eliminated. This reduction from full capacity resulted in an adjusted measured gross vehicle weight of 21,050 lbs and was used for all dynamic testing.
The performance of the bus is illustrated by a speed vs. time plot. Acceleration and gradeability test data are provided in Section 4, Performance. The average time to obtain 50 mph was 34.58 seconds.
A Fuel Economy Test was run on simulated central business district, arterial, and commuter courses. The results were 4.93 mpg, 5.69 mpg, and 9.03 mpg respectively; with an overall average of 5.91 mpg.
A series of Interior and Exterior Noise Tests was performed. These data are listed in Section 7.1 and 7.2 respectively.
