The U.S. model CRX (sometimes called a "Rex") was made from 1984 to 1991. The first generation was from 1984 to 1987, the second from 1988 to 1991. The Del Sol was known as the CR-X in all markets other than North America.
In 1984 the CRX was only available carburated and in two trim packages, the 1.3 and the base. The 1.3 had a SOHC 8V 1.3L inline four and a manual transmission. The base model had a SOHC 12V 1.5L inline four and was available with a manual or an automatic transmission. Power ratings were 55hp and 72hp respectivly. All models were equiped with CVCC.
In 1985 the Si became available with a power sunroof standard and a 1.5L fuel injected 12V inline four, an automatic transmission was not offered. The 1.3 became the HF and the base became the DX, both remained carburated. All carburated models were equiped with CVCC.
In 1986 and 1987 the CRX remained unchanged except for minor styling updates.
In 1988 the second generation was introduced. The DX again became the base model, and all models were fuel injected. The Hf was updated with a 1.5L SOHC 12V, the DX recieved a 1.5L SOHC 16V, and the Si a 1.6L SOHC 16V.
1989 saw door mounted seatbelts on the base and the Si.
In 1990 all models now recieved door mounted seatbelts and more side impact crash protection. The Si has rear disck brakes as standard.
1991 was the final year for the CRX in the United States, there were no major changes from 1990.
