The Lexus IS dates back to 1998, when it was introduced as an entry-level luxury car mainly in Japan and the United States. Initially launched as a four-door sedan and five-door wagon, the IS didn’t receive a two-door version until the second-generation model came in 2006. However, the Japanese only built a convertible, postponing the coupe for a few more years. The much-anticipated coupe has finally arrived for the 2015 model year, about 12 months after Lexus unveiled the third-generation IS. But unlike the latter, the coupe carries the RC F nameplate.
