The fourth generation Corvette was the
first complete redesign of the Corvette since 1963. Production was
to begin for the 1983 model year but quality issues and part delays
resulted in only 43 prototypes for the 1983 model year being
produced that were never sold.
Regular fourth generation production began on January 3, 1983; the
1984 model year and delivery to customers began in March 1983. The
1984 model carried over the 350 cu in (5.7 L) L83 slightly more
powerful (5 bhp) "Crossfire" V8 engine from the final 1982 third
generation model. New chassis features were aluminum brake calipers
and an all-aluminum suspension for weight savings and rigidity. The
new one piece targa top had no center reinforcement. A new
electronic dashboard with digital liquid crystal displays for the
speedometer and tachometer was standard. Beginning in 1985, the 230
bhp (170 kW) L98 engine with tuned port fuel injection became the
standard engine
