The designation scheme for U.S. Mercedes-Benz models was changed effective with the 1994 model year. The designation "E320" was used for all the E-class models with that engine. The previous suffixes of "CE" and "TE" were eliminated. Instead the cars were referred to as "E320 Coupe," etc.
The Sportline package was an option on the coupe and sedan.
