The third generation was released in 1984. The separate five-door hatchback and wagon models were merged into a four-door "shuttle wagon." An additional two-seat coupe style—labeled CRX—was introduced, noted for its compact dimensions and light weight. The third generation Civic saw the introduction of the long running four-cylinder D series engine including a new 1.5 L (91.5 cu in) CVCC engine. 1984 also saw the release of a high-performance Si model for the Japanese market, featuring upgraded suspension and the 1.6 L (97.6 cu in) DOHC ZC engine which was rated at 130 PS. Si models were offered in the US as a 3-door Civic Si hatchaback and the CRX Si variant with a 91 horsepower (68 kW) fuel injected SOHC 12-valve engine. A 4WD model was introduced for the first time in 1984, and later upgraded in 1987.
