Motor Coach Industries submitted a model D4500, diesel-powered 58 seat (including the driver) 45-foot bus, for a partial STURAA test in the 12 yr/500,000 mile category. The Federal Transit Administration determined that the following test would be performed; 1.3 Replacement and/or Repair of Selected Subsystems, 4. Performance, 6. Fuel Economy, 7.1 Interior Noise (stationary only) and 7.2 Exterior Noise (stationary only). Testing started on April 11, 2008 and was completed on June 10, 2008. 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 58 passengers including the driver. Free floor space will accommodate 31 standing passengers resulting in a potential load of 89 persons. At 150 lbs per person, this load results in a measured gross vehicle weight of 49,900 lbs.
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 29.21 seconds.
A Fuel Economy Test was run on simulated central business district, arterial, and commuter courses. The results were 2.33 mpg, 2.60 mpg, and 5.23 mpg respectively; with an overall average of 2.87 mpg.
A series of Interior and Exterior Noise Tests was performed. These data are listed in Section 7.1 and 7.2 respectively.
