In 1971 A new 5.3 L twelve-cylinder Jaguar V12 engine was introduced, with uprated brakes and standard power steering. The short wheelbase FHC body style was discontinued and the V12 was available only as a convertible and 2+2 coupé. The convertible used the longer-wheelbase 2+2 floorplan. The Series 3 is easily identifiable by the large cross-slatted front grille and flared wheel arches, and a badge on the rear that proclaims it to be a V12. Cars for the US market were fitted with large projecting rubber bumper over-riders to meet local collision regulations, but those on European models were considerably smaller. US models also have side indicator repeats on the front wings. There were also a very limited number of six-cylinder Series 3 E-Types built. These were featured in the initial sales literature.
