The Mercedes-Benz W140 was a series of flagship vehicles 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 late 1993 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. In 1996 the coupé models following a mid-life update where separated into the CL-class. The W140 series S-Class was superseded by the W220 S-Class in 1999 after an eight year production run, the coupé by the C215 CL-Class for model year 2000.
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 upon encountering an obstruction, rear-parking markers which rose from the rear wings (discontinued on later vehicles, and replaced with sonar-assisted parking) and a heating system which emitted warm air after the engine was turned off. The vehicle is believed to have cost Mercedes-Benz over $1 billion to develop.
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 percent 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.[citation needed]

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 1994, Mercedes-Benz made Electronic Stability Control an optional fixture to both sedan and coupé body styles in the W140 range. Both the sedan and coupé body styles were equipped with Acceleration Slip Regulation (ASR) as a standard feature.
Like its predecessor, the car was available in two wheelbase lengths (short W140 and long V140) along with the C140 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 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 1994 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 1994. The clear turn signal indicator lenses on the front were the most obvious change, as was the grille including a new and distinctive one for S600's. Headlamps were fitted with separate low H7, H1 fog, and high H1 beam reflectors in 1995, pre 1995 used an H4 bulb and H3 for the fog lamp. In 1994 the two tone exterior bumpers were painted to match the upper portions of the vehicles and the rear indicator lenses became clear.
Height of the W140 production models varied between years (1992-94 W140 Sedan: 58.7 in; 1992-94 V140 Sedan: 58.9 in; 1995-96 W140 Sedan: 58.4 in; 1995-99 V140 Sedan: 58.3 in; C140 Coupe: 56.7 in; 1997-99 W140 Sedan: 58.5 in).

[edit] Princess Diana's death
Main article: Death of Diana, Princess of Wales
It has been noted that Diana, Princess of Wales died while travelling in a Mercedes-Benz S280 (W140), and it was an unfortunate side-effect of her high-profile death that the Mercedes' safety record was called into question. However, it is important to note that all of the car in question's safety systems functioned as designed, expanding both drivers' and passenger airbags and saving the life of Trevor Rees-Jones, Dodi Al-Fayed's bodyguard, who benefited from the front-passenger airbag. The fact that three of the car's four occupants were killed in the crash should be attributed more to the high speed of the vehicle, the intoxication of the driver and the fact that three of the four of the occupants were not wearing a seatbelts(only the suvivor). The Mercedes safety systems were circumvented by the driver's and passengers' decisions.

[edit] Features

[edit] Safety
The W140 S-Class introduced several safety innovations which have since become commonplace among many vehicles.[2]
Braking system. The V8 and V12 W140 models distributed more braking power to the rear wheels, increasing stopping effectiveness. In 1996, the W140 received Brake Assist, which engaged during emergency maneuvers to boost braking power to maximum.
Electronic Stability Program (ESP) was introduced in 1996. ESP used on-board computers to improve vehicle handling response during difficult driving conditions. This was a Mercedes developed system, which has since been licensed to other manufacturers.
Side airbags and seat occupancy sensors were introduced in 1996.

[edit] Comfort and convenience
Double-paned soundproofed glass was a new S-Class innovation first fitted on the W140. This form of window glazing allowed for improved soundproofing, reduced condensation, and other insulation benefits.
Electrically-operated exterior mirrors could be folded at the flick of a switch to ease driving in narrow spaces.
'Parameter steering' was a system which made low-speed driving easier by reducing the effort required to maneuver in speed-sensitive situations such as parking.
Rear-parking markers, or guide rods. These rods extended from the rear corners of the trunk lid when in reverse, providing the driver with a guideline for rear maneuvers. In 1995, this system was replaced by the sonar-based Parktronic system which measured the distance of the bumpers to nearby obstacles.
Rain-sensing windshield wipers.
Electrically-operated automatic-dimming inside rear-view mirror that tied into the seat and steering wheel memory (first introduced on the R129 SL convertible).
Orthopedic seats were an expensive option from the factory but consisted of several different air cushions in the seat that the user can inflate and deflate to find the perfect driving position.
Dual-zone climate control.
Reclining and heated rear seats (introduced with the W126 S-Class sedans).
The climate control sytem could be set to operate for 20 minutes after the engine had been turned off.

[edit] Drivetrain technologies
The W140 featured a newly-developed double wishbone front axle and a multi-link independent rear suspension.
