differs from the earlier versions (IV and V) in three ways. The description of intrusion measurements provides methods for establishing the reference coordinate systems for intrusion measurements in cars, passenger vans, and utility vehicles (previously version IV) as well as for pickup trucks and vehicles with removable or convertible roofs (previously version V). Also, the calculation by which intrusion measurements are adjusted to reflect movement of the steering wheel, instrument panel, and toepan relative to the driver has been added. Finally, the sign convention and digital filtering for electronically recorded measurements has been changed to comply with the Society of Automotive Engineers (SAE) recommendations for impact testing
