E-Class

The Mercedes-Benz E-Class is a range of executive cars manufactured by Mercedes-Benz in various engine and body configurations. The E initially stood for Einspritzmotor, (German for fuel injection engine); a new feature in volume production vehicles at the time that the E-Class first appeared, with the E as a suffix to the engine nomenclature (e.g. 230E) in the 1950s. It was not until the launch of the facelifted W124 that the E was used as a prefix (i.e., E220) and the model referred to officially as the E-Class (or E-Klasse). At this time all Mercedes cars used fuel injection and the company felt it was not necessary to add this as a distinguishing feature. Due to the E-Class's size and durability, the cars also frequently serve as taxis in European countries. Older models like the W123 and W124 are used in Malaysia as inter-state taxis, and the W211 is used in Singapore as a taxi. Mercedes-Benz also offers special-purpose vehicles (e.g., police or ambulance modifications) from the factory.

Tuning AMG

Several companies have become car tuners (or modifiers) of Mercedes Benz, in order to increase performance and/or luxury to a given model.

AMG is Mercedes-Benz's in-house performance-tuning division, specialising in high-performance versions of most Mercedes-Benz cars. AMG engines are all hand-built, and each completed engine receives a tag with the signature of the engineer who built it. AMG has been wholly owned by Mercedes-Benz since 1999. The 2009 SLS AMG, a revival of the 300SL Gullwing, is the first car to be entirely developed by AMG.

There are numerous independent tuners including, Brabus, Carlsson, Kleemann, Renntech and MKB.

Mercedes Innovations

Numerous technological innovations have been introduced on Mercedes-Benz automobiles throughout the many years of their production, including:

• The internal combustion engined automobile was developed independently by Benz and Daimler & Maybach in 1886
• Daimler invented the honeycomb radiator of the type still used on all water-cooled vehicles today
• Daimler invented the float carburetor which was used until replaced by fuel injection

Environmental Record

Mercedes-Benz has developed multi concept cars with alternative propulsion, such as hybrid-electric, fully electric, and fuel-cell powertrains. At the 2007 Frankfurt motor show, Mercedes-Benz showed seven hybrid models, including the F700 concept car, powered by a hybrid-electric drivetrain featuring the DiesOtto engine. In 2009, Mercedes-Benz displayed three BlueZERO concepts at the North American International Auto Show. Each car features a different powertrain - battery-electric, fuel-cell electric, and gasoline-electric hybrid. In the same year, Mercedes also showed the Vision S500 PHEV concept with a 19 miles (31 km) all-electric range and CO₂ emissions of 74 grams/km in the New European Driving Cycle.

In Formula One

Mercedes-Benz took part in the world championship in 1954 and 1955, but despite being successful with two championship titles for Juan-Manuel Fangio, the company left the sport after just two seasons. He is considered by many to be the best F1 driver in history.

Mercedes-Benz returned as an engine supplier in the 1990s and part-owned Team McLaren for some years, to which it has supplied engines engineered by Ilmor since 1995. This partnership brought success, including drivers championships for Mika Häkkinen in 1998 and 1999, and for Lewis Hamilton in 2008, as well as a constructors championship in 1998. The collaboration with McLaren had been extended into the production of roadgoing cars such as the Mercedes-Benz SLR McLaren.

In 2007, McLaren-Mercedes was fined a record US$100 million for stealing confidential Ferrari technical data.

In 2009, Ross Brawn's newly conceived Formula One team, Brawn GP used Mercedes engines to help win the constructor's championship, and Jenson Button to become champion in the F1 drivers' championship. At the end of the season, Mercedes-Benz sold its 40% stake in McLaren to the McLaren Group and bought 70% of the Brawn GP team jointly with an Abu Dubai based investment consortium. Brawn GP was renamed Mercedes GP for the 2010 season and is, from this season on, a works team for Mercedes-Benz.

The Alphanumerics

Until 1994, Mercedes-Benz used an alphanumeric system for categorising their vehicles, consisting of a number sequence approximately equal to the engine's displacement in liters multiplied by 100, followed by an arrangement of alphabetical suffixes indicating body style and engine type.

• "C" indicates a coupe or cabriolet body style.
• "D" means the vehicle is equipped with a diesel engine.
• "E" (for "Einspritzen") means the vehicle's engine is equipped with petrol fuel injection. In most cases (the 600 limousine being the exception), if neither "E" or "D" is present, the vehicle has a petrol engine with a carburettor.
