SUVs - Suddenly Upside-down Vehicles: Document Excerpt: Handling Recommendations

In 1982, engineers recommended a 3 to 4 inch widening of the vehicle track (width) if "major improvements" in "roll characteristics" were to be achieved. The Bronco II/Explorer line of vehicles was not widened until model year 2002, when the Explorer track was widened 2.5 inches. There were 3,826 deaths in 3,802 Bronco II and Explorer rollovers between 1983 and 2001.
