Freedom Motors USA, Inc. submitted a model 2009, gasoline-powered 4 seat (including the driver) plus 2 wheelchair positions,  converted Toyota Sienna LE mini-van, for a 4 yr/100,000 mile STURAA test. The odometer reading at the time of delivery was 18,728 miles. Testing started on September 8, 2009 and was completed on November 25, 2009. 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 September 21, 2009 and was completed on November 13, 2009.


The interior of the test vehicle configured with seating for 4 passengers including the driver plus 2 wheelchair positions. There is no free floor space. At 150 lbs per person plus 2 wheelchair positions (600lbs each), this load results in a measured gross vehicle weight of 5,960 lbs. In order to avoid exceeding the GAWR (2,845 lbs) of the front axle and (2,845 lbs) of the rear axle, ballast for 2 seated passengers was eliminated. This reduction from full capacity resulted in an adjusted measured gross vehicle weight of 5,740 lbs and was used for all dynamic testing. The middle seated load weight segment was performed at the same 5,740 lbs and the final segment was performed at a curb weight of 3,960 lbs. Durability driving resulted in no unscheduled maintenance.


Accessibility, in general, was adequate, components covered in Section 1.3 (Repair and/or Replacement of Selected Subsystems) along with all other components encountered during testing, were found to be readily accessible and no restrictions were noted.


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 vehicle encountered no failures during Structural Durability Testing.


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. 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 10.66 seconds.


The Shakedown Test produced a maximum final loaded deflection of 0.173 inches with a permanent set ranging between -0.006 to 0.003 inches under a distributed static load of 2,700 lbs. The Distortion Test was completed with all subsystems, doors and escape mechanisms operating properly. No water leakage was observed throughout the test. All subsystems operated properly.

The test vehicle was not equipped with any type of tow eyes or tow hooks, therefore the Static Towing Test was not performed. The Dynamic Towing Test was performed by means of a front-lift tow. The towing interface was accomplished using a hydraulic under-lift wrecker. The test vehicle was towed without incident and no damage resulted from the test. The Jacking and Hoisting Tests were also performed without incident. The bus was found to be stable on the jack stands, and the minimum jacking clearance observed with a tire deflated was 4.4 inches.


A Fuel Economy Test was run on simulated central business district, arterial, and commuter courses. The results were 14.35 mpg, 15.34 mpg, and 24.00 mpg respectively; with an overall average of 16.56 mpg. A series of Interior and Exterior Noise Tests was  performed. These data are listed in Section 7.1 and 7.2 respectively.
