This SAE Recommended Practice defines a set of measurements and standard procedures for motor vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way. In addition, some dimensions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected. Also, care should be taken to not confuse design intent measurements with those taken on a physical property. It is intended that the dimensions and procedures described in this practice be generic in their application to both the HPM, described in J826, and the HPM-II, described in J4002. In some circumstances, the figures may only reflect one or the other. Unless otherwise specified, all dimensions are measured normal to the three-dimensional reference system (see SAE J182), except ground-related dimensions, which are defined normal to ground. All dimensions are taken with the vehicle at curb weight unless otherwise specified. All dimensions are measured on the base vehicle and do not include Regular Production Options (RPO) or accessory parts, unless otherwise specified. Although many terms and dimensions use human body parts in their name, they should not be construed as measures that indicate occupant accommodation, capabilities, or comfort. The majority of changes in this version of J1100 are editorial in nature. Specifically, fifty-five (55) dimension definitions were modified and thirteen (13) were added to provide better guidance and clarity. Where feasible, procedures and figures were updated to better align to existing standards. Additional code consolidation was implemented, consistent with the 2002 version, and is described in Section 4. Significant revisions were limited to certain HPM measures of leg room (L51-x) and knee clearance (L48-x), particularly for short- and long-coupled seating. Approach, departure, and ramp breakover angles (see Table 24) were revised to be consistent with definitions in the Code of Federal Regulations (49CFR523). Lastly, a metric (W113) was added to define the axle width of a vehicle, independent of any camber or wheel offset.
