The V-12 was offered from 1971–1975. During the four-year production run, a total of 15,287 examples were produced. The Series III cars are very refined among the E-Types. The new V-12 production engine did not fit into the two-seat E-Type coupé, so the new motor was offered in roadster and 2+2 configurations only. Jaguar widened the front and rear track to accommodate the bigger and more powerful motor, which also necessitated a longer hood and chassis with a bigger air intake and grille.
