1993 was the 40th anniversary for Corvette. In order to celibrate the 40th Anniversary package was created. The 40th Anniversary package included special Ruby Red Metallic paint and a Ruby Red interior. It also has headrest embroidery and bright emblems on the hood, deck and side-gills. All leather seats had the 40th anniversary badge on the headrest, the base black cloth seats did not. Three changes were made to the base engine to make it much quieter. The ZR-1 got a huge boost this year jumping 15 horsepower from 385 to 405. Torque was also improved from 370 lb-ft to 385 lb-ft. This was accomplished through porting changes on the head and valvetrain, an electric EGR valve improving emissions, platinum tipped spark plugs, and four bolt main bearing caps. A new passive entry system that unlocked the car when a special key fob was near the car was optional. A new polished wheel was standard and the tire and wheel sizes were reduced by 1 all around on all 1993 Vettes except ZR-1.nbsp
