Rolls-Royce Corniche - Corniche IV

Corniche IV

The car was reworked for 1992 as the Corniche IV, presented at the Detroit Auto Show in January. By this time production had moved to Crewe, in preparation for the 1994 closure of Mulliner Park Ward. Mechanically, the IV benefitted from the four-speed GM4L80 automatic transmission rather than the old three-speed GM400 unit. Adaptive suspension was also introduced. Visually there is nearly no difference between the Corniche III and IV although a glass rear window was now fitted, a major upgrade from the previous plastic unit. The rest of the top mechanism was improved as well, and no longer required manual latching. CFC-free air conditioning was specified, as were driver and passenger airbags. In October 1992 a 21st anniversary Corniche was presented. 25 cars were built, all finished in Ming Blue with a cream hood with a silver plaque on the dash.

In August 1993 an improved engine with 20 percent more power became standard fitment. The last 25 Corniche models to be built, completed in the summer of 1995, were unique turbocharged versions and were called the Corniche S. In total, 5,146 Corniche Convertibles had been built, plus 1,108 Saloons (Coupés, that is), and 140 Bentley Corniches.
