The last major revision to the Volkswagen Beetle was released for the 1973 model year and designated the 1303 Super Beetle. The most noticeable differences from the 1971-1972 Super Beetle were larger "elephant foot" taillights and a new curved windshield, giving the car a more modern look and allowing for a larger dashboard. The instrument panel, formerly shared with the standard Beetle, was all-new and incorporated a raised speedometer pod, rocker-style switches and side-window defrosters. In the engine bay, the oil-bath air cleaner gave way to a dry element filter, and the generator was replaced with an alternator. To comply with federal regulations in the United States, 5 mph shock absorber bumpers were added in 1974 and fuel injection in 1975. 1976 was the last year of production for the Super Beetle sedan.
