To mark Corvette's 25th anniversary, the 1978 model received a major aerodynamic restyling with large wraparound back window and a fastback roofline.

Inside was a restyled, padded instrument panel with face-mounted round instruments and a new locking glove box that replaced the former map pocket. As in 1977, the seats had leather side bolsters, with either leather or cloth seating areas in a fine rib pattern.

Corvette's optional L82 high-performance 350-cid V-8 reached 220 hp as a result of a new dual-snorkel cold-air intake system, larger-diameter exhaust and tailpipes and lower-restriction mufflers.

Glass roof panels, which had been promised earlier, actually became available this year.
What Chevrolet described as "aggressive" 60- series white-letter tires also joined the option list for the first time.
