The Supreme Corporation submitted a model 34’ HD Chevy, diesel-powered 33 seat (including the driver) 32-foot bus, for a 10 yr/350,000 mile STURAA test.  The odometer reading at the time of delivery was 7,989 miles.  Testing started on August 8, 2005 and was completed on November 21, 2005.  The Check-In section of the report provides a description of the bus and specifies its major components. 

 The primary part of the test program is the Structural Durability Test, which also provides the information for the Maintainability and Reliability results.  The Structural Durability Test was started on August 9, 2005 and was completed on November 17, 2005.

 The interior of the bus is configured with seating for 33 passengers including the driver.  Free floor space will accommodate 20 standing passengers resulting in a potential capacity of 53 persons.  At 150 lbs per person, this load results in a measured gross vehicle weight of 22,890 lbs.  The first segment of the Structural Durability Test was performed with the bus loaded to a GVW of 22,890 lbs.  The middle segment was performed at a seated load weight of 19,860 lbs and the final segment was performed at a curb weight of 15,070 lbs.  Durability driving resulted in unscheduled maintenance and failures that involved a variety of subsystems.  A description of failures, and a complete and detailed listing of scheduled and unscheduled maintenance is provided in the Maintainability section of this report.

 The Reliability section compiles failures that occurred during Structural Durability Testing.  Breakdowns are classified according to subsystems.  The data in this section are arranged so that those subsystems with more frequent problems are apparent.  The problems are also listed by class as defined in Section 2.  The test bus encountered no Class 1 or Class 2 failures.  Of the twenty-five reported failures, eighteen were Class 3 and seven were Class 4.

          The Safety Test, (a double-lane change, obstacle avoidance test) was safely performed in both right-hand and left-hand directions up to a maximum test speed of 45 mph.
