The Mercedes-Benz W116 is a series of flagship luxury sedans produced from September 1972
History
The W116's development began in 1966, which was only a year after the launch of the W108/09. This was the first Mercedes-Benz sedan to feature the brand-new corporate styling theme, which endured until 1993, when the 190 was discontinued. The design, finalized in December 1969,
The W116 was presented in September 1972. The model range initially included two versions of the M110 engine (straight-six with 2746 cc displacement) — the 280S (using a Solex carburetor) and the 280SE (using Bosch D-Jetronic injection), plus the 350SE, powered by the M116 engine (V8 with 3499 cc displacement). After the 1973 oil crisis, a long-wheelbase 280SEL was added to the model range.
The larger 4.5-litre M117 V8 engines were developed in response to US emission regulations and initially fitted to the 350SL and 350SLC for the US market in 1972, which were renamed as the 450SL and 450SLC in 1973. Mercedes-Benz introduced the 450SE and 450SEL for both US and international markets in 1973. The 4.5-litre models were available with three-speed automatic gearboxes only, while the models with smaller 3.5-litre V8 engine could be ordered with a four-speed (and later five-speed) manual gearbox. The 450SE and 450SEL received a plusher interior, with velour or leather seats rather than the checkered cloth of the lesser models. The door cards had the velour or leather inserts.[6]
The 4.5-litre M117 V8 engines had 225 PS (165 kW) in most European and international markets, 190 hp (142 kW) for the US market, and 200 PS (147 kW) for Swedish and Australian markets.[5] The 450 models received a plusher interior as well, with velour or leather seats rather than the checkered cloth of the lesser models. The door cards were also of a different design, with pads being pulled up around the windows.[6]
The W116 had independent suspension and
The most notable W116 model was the high-performance, limited-production
Exclusive to the North American and Japanese markets was the 300SD, the world's first passenger car with a turbocharged diesel engine, which was introduced in 1978. No 300SD model was offered in Europe (where diesel engines were well-received and had tax advantages) until 1991, when the W140 300SD was finally introduced in Europe and international markets.
The 450SE was named the
Production totaled 473,035 units. The W116 was succeeded by the W126 S-Class in 1979. The W116 was sold throughout Europe, the Americas, Asia, the Middle East, Africa, and Australia.
Fuel injection
In 1975, the W116 was upgraded with a new fuel injection system to comply with revised exhaust emission standards in European markets. A slight power reduction was a result of this update. In 1978, a series of engine upgrades restored original performance levels with new fuel injection systems. Initially the early models (1973-1974) of the W116 with the Twin Cam inline 6 used the D-

Hydropneumatic suspension
W116 was first model from Mercedes-Benz to feature the hydropneumatic suspension system. While the principle is similar to Citroën’s, Mercedes-Benz made some changes. The hydraulic pump was driven by the timing chain instead of rubber belt for more reliability (Citroën’s system would lead to loss of hydraulic power if belt failed). Mercedes-Benz utilised the hard rubber dampers as temporary dampers in event of hydraulic failure. The height adjustment had a smaller range of height as compared to Citroën (5 cm versus 50 cm). Unlike Citroën, the car did not “sink” to the ground after shutting off the engine, and the driver did not have to wait for the hydraulic power to spool up and lift the car to the operating height.
The full hydropneumatic suspension system was fitted to the 450SEL 6.9 as standard. In 1977, the self-levelling rear suspension system was offered for 450SEL as extra cost option outside the North American market.
North American sales
North America was a key market for the W116. The model range for the U.S. market at launch was 280SE, 450SE, and 450SEL. For 1975, 280S was launched as a response to the 1973 oil crisis. The 6.9 was added in 1977 with the MSRP of $38,230 while 280S and 450SE were dropped due to slow sales. 300SD, the world’s first passenger car with turbocharged diesel engine, was launched in the United States and Canada in 1978: the S-Class model with turbocharged diesel engine was exclusive to the North American and Japanese markets until 1991.
[10] It had a turbocharged 3.0-litre inline-five diesel engine developed from that of the C111 experimental vehicle. It was developed to help Mercedes-Benz keep from falling afoul of the Corporate Average Fuel Economy (CAFE) standards introduced in 1975; it became a best seller and helped considerably raise Mercedes-Benz' average fuel economy.[10]
Due to the modifications demanded by the U.S. Government, U.S. Models of the Mercedes-Benz W116 were described by journalists as if a "beautiful car was beaten with the malaise ugly stick."[11]

_sedan_(2016-01-29)_02.jpg)
The W116 S-Class incorporated a broad variety of Mercedes-Benz safety innovations.
- Four wheel anti-lock brakeswere first featured as an option on the 1978 W116 S-Class. This system prevents the wheels from locking while braking. The system improves steering control during hard braking situations, and to shorten brake distances.
- Strengthened body structure. The W116 featured a more stable security passenger cell with a stiffened roof frame structure. High strength roof and door pillars, along with other reinforced zones, provided enhanced vehicle occupant protection.
- Deformation zones (crumple zones) in the front and rear.
- A padded dashboard, deformable switches and controls, and a four-spoke steering wheel with impact absorber and broad impact cushion aimed to reduce occupant injury during collisions.
- The fuel tank was no longer fitted at the rear end, but was now placed above the rear axle for added protection.
- Wraparound turn signals made it easier to communicate with nearby drivers.
