In 1981, there was only one powerplant available, a engine that, like the L-48 base engine the previous year, produced the , but was now designated the L81. The motor was certified in all states and available with manual or automatic transmissions. Chrome air cleaner lids and cast magnesium valve covers dressed up all engines. The light weight 4 into 1 stainless steel exhaust manifolds and computer control system introduced on the California engines the previous year were now standard, as was an auxiliary electric engine cooling fan. This, the last C3 available with a manual transmission, so equipped, had a published 0-60 mph in 8.1 seconds. This model year was the first corvette to use a fiberglass rear leaf spring, now a Corvette trademark. The spring saved thirty-six pounds, but was limited to base suspensions with automatic transmission. When equipped with Delco's brand new optional ETR (Electronically Tuned Receiver) radio with a digital clock, the quartz analog instrument panel clock was replaced with an oil temperature gauge. The cast aluminum wheels, optional since ’76, were now ordered on 90 percent of the cars at a cost of $428. New options included a power adjustable driver’s seat and power remote outside mirrors. In mid-1981 production relocated from St. Louis to Bowling Green, Kentucky, and several two-tone paint options were offered.
