The 1980 Corvette The 1980 Chevrolet Corvette was the first since 1974 to have more than one engine displacement. Unfortunately the new option was a 305 cubic inch destined for the California market to meet the stringent smog laws. This engine was required for California and was only available with the automatic transmission. The good news is that the '80 was 250 pounds lighter than the 1979. The hood and doors were made thinner saving weight.
The tops decreased in density due to the use of microscopic beads in their construction. The rear differential housing and supports were manufactured from aluminum which also decreased weight.
On the 350 cubic inch cars the intake manifold was made from aluminum. The California 305 ci engine got a stainless steel exhaust manifold. The front and rear spoilers from the '78 pace car were now molded into the front and rear bumper pieces and were standard. All '80 Vettes now had the 85 MPH speedometer.
