NEW FLYER Download PDF Report
New Flyer of America submitted a model XD60, diesel-powered 50 seat (including the driver) 60-foot bus, for a partial STURAA test in the 12yr/500,000 mile category. The Federal Transit Administration determined that the following tests would be performed: 4.1 Performance Test, 4.2 Brake Test, 6. Fuel Economy, 7.1 Interior Noise Test, 7.2 Exterior Noise Test and 8. Emissions Test. Testing started on January 22, 2013 and was completed on May 22, 2013. 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 50 passengers including the driver. Free floor space will accommodate 73 standing passengers resulting in a potential load of 123 persons. At 150 lbs per person, this load resulted in a measured gross vehicle weight of 58,600 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 47.59 seconds. Top speed acquired on the dynamometer was 66.34 mph. The Stopping Distance phase of the Brake Test was completed with the following results; for the Uniform High Friction Test average stopping distances were 30.11’ at 20 mph, 60.06’ at 30 mph, 102.90’ at 40 mph and 131.22’ at 45 mph. The average stopping distance for the Uniform Low Friction Test was 31.21’. There was no deviation from the test lane during the performance of the Stopping Distance phase. During the Stability phase of Brake Testing, the test bus experienced no deviation from the test lane but did experience pull to the left during both approaches to the Split Friction Road surface. The Parking Brake phase was completed with the test bus maintaining the parked position for the full five-minute period with no slip or roll observed in both the uphill and downhill positions.
A Fuel Economy Test was run on simulated central business district, arterial, and commuter courses. The results were 2.73 mpg, 3.12 mpg, and 5.56 mpg respectively; with an overall average of 3.34 mpg.
A series of Interior and Exterior Noise Tests was performed. These data are listed in Section 7.1 and 7.2 respectively.
The Emissions Test was performed. These results are available in Section 8 of this report.
