The 1961 Corvette featured four taillights, a treatment that continues to this day. Engine displacement remained at 283 cubic inches, but power output increased for the two fuel-injected engines to 275 hp and 315 hp. Power ratings for the dual-four barrel engines did not change (245 hp and 270 hp) but this was the last year of their availability. This was the last year for contrasting paint colors in cove areas, and the last two-tone Corvette of any type until 1978. Also debuting in 1961 was a new boat-tail design later used on the C2.
