The 1977 Corvette
The 1977 Corvette was no longer badged with the "Sting Ray" script. The tried and
true orange engine color was changed to blue between August and September of 1976.
Some early production 1977 Corvettes were still built with the orange painted engines
but most have the new blue engines. Leather seats were standard but cloth seat inserts
were optional. A voltmeter replaced the previous ammeter in the gauge cluster. The
"Door Ajar" and "Headlamp Up" warning lights were removed. The Manual shift lever
grew an inch but with shorter travel. Power steering and brakes were standard for
the first time. The steering wheel as wrapped in leather to match the interior and
the steering column was shortenend. The padded sun shades could be swiveled to cover
the side windows now. A new crossed flags badge adorned the front of the hood between
the headlights as well as on the fuel filler door. The glass roof panels that were
announced this year were never deliverd on a production car. The 500,000 Corvette
rolled off the line this year.
