The 1993 model year

Overview

For 1993, the U.S.-era W140 sedan roster expanded to five models: 300 SE, turbodiesel 300 SD, and long-wheelbase 400 SEL, 500 SEL, and 600 SEL. These are the final pages in this catalog to use the engine-first SE/SD/SEL naming before Mercedes-Benz's June 1993 nomenclature change appears in the following model year.

Year over year

What changed

The 300 SD added a turbodiesel sedan, and the 4.2-liter model moved from 400 SE to long-wheelbase 400 SEL form.
The 500 SEL and 600 SEL continued as long-wheelbase V8 and V12 flagships.

Worth knowing

Notable

The year is an important naming boundary: the sourced 1993 roster is not relabeled retroactively with 1994-style S-prefix badges.

Living with it

Reliability & ownership notes

Service records matter on every W140; inspect the pneumatic convenience system, all electronic equipment, rear window regulators, power-steering leaks, and engine mounts before purchase.
The club guide identifies pre-1996 evaporator leakage and 1993–1995 biodegradable wiring harnesses as specific inspection points; verify repairs on the individual car rather than assuming every example is affected.
Match service parts to the exact engine, transmission, market, and build date shown on the data plate; a shared W140 body does not make six-cylinder, V8, V12, and diesel fitment interchangeable.
