Mercedes-Benz S-Class Sedan (W140)

The W140 S-Class was Mercedes-Benz at its most imposing — a flagship of extraordinary scale, weight, and engineering depth that arrived in the early 1990s as the ultimate expression of the traditional German luxury saloon.

Double-glazed windows, hydraulically damped closing aids, short and long wheelbases, and engines from a 2.8-liter six through 4.2- and 5.0-liter V8s to the company’s first passenger-car V12 made the W140 the most comprehensively equipped S-Class yet. In June 1993 the whole range was renamed — 300 SE became S 320, 500 SEL became S 500 lang — and the SEC coupé on C140 shared the platform in two-door form. Critics called it excessive; owners called it exactly right.

Mercedes-Benz built 406,710 saloons between 1991 and 1998; with the 26,022 C140 coupés, the 140 series came to 432,732 cars.
