First introduced in 1969, the Corvette ZR1 has been offered for all generations since the C3, except for the C5 model. This pretty much makes it a constant presence in the Corvette lineup. However, when Chevy revised the ZR1 for the first time in 1990 after a 21-year absence, it didn’t offer a convertible version. The drop-top was ignored with the C6 model, produced between 2009 to 2013, too. Chevrolet finally took the roof of the ZR1 at the 2017 Los Angeles Auto Show, unveiled the convertible model only weeks after it launched the beefed-up coupe. This makes the C7-gen Corvette ZR1 Convertible the first topless ZR1 in 48 years, and the event requires a bit of celebration with a proper comparison between the two.
