The Mercedes-Benz W140 is a car that was manufactured by the German automotive marque Mercedes-Benz. The car premiered at the Geneva Motor Show in March 1991, with the first examples rolling off the production line on August 6 1991. Short (SE) and long (SEL) wheelbase sedans were offered initially, as well as the coupé (SEC) body style from January 1992. Like all Mercedes-Benz lines, the W140 S-Class was rationalized in 1994 using the new "letter-first" nomenclature, dropping the named distinction between body styles. The SE/SEL/SEC cars were renamed the S-Class, with alphanumerical designations inverted. For example the both 500SE and 500SEL became S500 regardless of wheelbase length. The W140 series S-Class was superseded by the W220 S-Class in 1999 after an eight year production run, and C215 CL-Class for 2000.

Design and engineering

As with its predecessor, the W140 was the first of the "next generation" of Mercedes-Benz models to feature the company's new design theme. The W140 introduced new innovations such as double-pane window glazing, self-closing doors and boot lid, electric windows which lowered back down when encountering an obstruction, rear-parking markers which appeared on the rear wings and a heating system which emitted warm air even after the engine was turned off.

For details like this, the W140 is often known as the last Mercedes to be "overengineered", a Mercedes trait that was costing the company in product delays and overbudgeting. For the consumer, the W140 cost a considerable 25% more than its predecessor, the W126. In addition, the intense pressure from Infiniti and Lexus led to adding more features and options as to set the W140 apart from the rest and to justify the higher price.

The W140 was to feature air suspension as an option, but Mercedes was still perfecting the technology and chose to launch air-suspension in the next generation S-Class in 2000. Following the mid-year facelift in 1995, Mercedes-Benz made Electronic Stability Control a standard fixture to both sedan and coupé body styles in the W140 range.

Like its predecessor, the car was available in two wheelbase lengths along with the shorter-wheelbased W140 coupé. In 1992, a new 6 litre 408 horsepower V12 engine joined the lineup for the first time with the 600SE, 600SEL and 600SEC. A "V12" badge was affixed to the C-pillar. In 1995, grille was redesigned on all models, including a new and distinctive one for S600's.

In 1993, the 408 horsepower V12 engine was slightly detuned to 389 horsepower to comply with tighter emission control regulations in the United States and Europe. The V8 models were tuned down from 322 horsepower to 315 horsepower.

The W140 S600 was available with a leather dashboard and a suede headliner, unlike the V8 and inline 6-cylinder models. In 1995 the S600 also came with a wood/leather steering wheel, wood/leather gear shifter, wood rear ashtray covers, and two tone leather seating – further distinctions from its lower rung siblings.

Following the new Mercedes-Benz tradition of mid-life facelifts (starting with the W126 in 1986), the W140 received a minor facelift in 1995. The clear turn signal indicator lenses on the front and rear were the most obvious changes. Headlamps were fitted with separate low H1 and high H7 beam reflectors in 1995, pre 1995 used a H4 bulb and H3 for the fog lamp. In 1997 the two tone exterior bumpers were painted to match the upper portions of the vehicles.

Legacy

Criticised at launch for being overweight, oversized and generally unpleasing on the eye (attributes that were somewhat at odds with the so-called 'caring, sharing 1990s'), the sheer depth of engineering in the W140 has stood the test of time, and there are those that still prefer the car's unwavering capability and strength to that offered by later models. A properly maintained W140 is still a viable proposition today. Over-engineered at launch it may have been, but as a way of showcasing the company's talents, the W140 was unbeatable.
