Bumpers for 1968 changed to a smooth, round, one-piece design, constituting a relatively dramatic alteration to the rarely-updated Beetle exterior, and enthusiasts consider any Beetle built after 1968 a "late model." The 1968 "sarcophagus" seat backs had large, integrated headrests.
Handling was significantly modernized with a new independent rear suspension in 1969, and advertisements boasted 89 improvements for the 1971 debut of the Super Beetle, including a larger trunk, coil-spring front suspension, and 60-hp engine. Super Beetles (1971-1974) are most easily distinguished from Standard Beetles by the spare tire oriented flat inside the trunk, rather than upright.
Windshields were bigger for 1973, as were the new 5 mph government-mandated bumpers. The front seats adjusted "77 ways." Electronic fuel injection became standard in 1975, but the next year would be the very last for the sedan in the U.S., and Beetle convertibles would be phased out after 1980.
Production would continue elsewhere until 2003, adding another million-plusBeetles to roadways beyond U.S. borders.
