In 1983 for the 1984 model year, Honda introduced an all-new two-seater that shared the drivetrain with the Civic but offered unique styling and interior furnishings. At its introduction, the CR-X was available in Japan through Honda Verno dealership sales channels, and accompanied the Vigor, the Quint, and the Prelude. In North America, the CRX was marketed in two versions: economy and sport. The economy model used a new aluminum 1.3-liter CVCC four-cylinder engine. The sportier model featured an aluminum 1.5-liter 12-valve engine and was available with either a 5-speed manual or a 3-speed automatic transmission.
