The first generation W202 C-Class was introduced in 1993, as a replacement for the Mercedes-Benz W201 (190), and proved immensely popular, quickly becoming Mercedes-Benz's best-selling class of vehicles worldwide. Much of its popularity was accredited to the lower pricing point, when compared to other Mercedes-Benz models. The C-Class sedan was the company's entry-level model up until 1997, when Mercedes launched the A-Class supermini. Styling themes were carried over from the previous W201 series, but the new series had a smoother and rounder design than the previous generation of compact Mercedes.
Engine: On its debut, the C-Class was the only Mercedes model with a complete lineup of multivalve engines. The new family of four cylinder petrol units, called M111, debuted in the C 180 (1.8 L, 122 PS (120 hp/90 kW)), C 200 (2.0 L, 136 PS (134 hp/100 kW) and C 220 (2.2 L, 150 PS (148 hp/110 kW), the only four cylinder of the range sold in the U.S.). In 1996 the C 220 was replaced by the C 230, enlarged to 2.3 L displacement but with the same output, although with torque increased to 220 N·m (162 ft·lbf). . The top of the range was the C 280, with a four-valve-per-cylinder straight-6 engine, capable of reaching 193 PS (190 hp/142 kW).
Four cylinder diesel models were equipped with the same OM601 engine of the 190, in the 2.0 L and 2.2 L versions. Many of these diesel variants were sold as taxis, due to their low fuel consumption and strong reliability. There were also more powerful five cylinder engines (OM605) which were available in naturally aspired (C 250 D) and turbocharged (C 250 TD) forms. The Turbodiesel was introduced in 1995 and is one of the novelties in the engine range available from this year. The most important was a supercharged version of the M111 straight four, the C 230 Kompressor, using a Roots-type supercharger to generate 193 PS (190 hp/142 kW) at 5300 rpm: Mercedes-Benz reused supercharger technology after 50 years. Export models in Portugal and Italy featured a supercharged version of the smaller 2.0 L (C 200 Kompressor), which had a similar output of the C 230 Kompressor.
With the 1997 restyling, a lot of things changed under the hood of the Baby Benz. The most important innovation was the OM611, the first turbodiesel engine equipped with a Common rail direct injection system (developed by Bosch and FIAT). The new model was named C 220 CDI, and had an output improvement of 30 PS compared with the C 220 Diesel, better fuel average and lower emissions. Another revolution regarded six cylinder engines: the legendary straight six were replaced by an all new family of V6. These new engines, the M112, featured SOHC heads instead of the previous DOHC, three valves per cylinder, instead of four, and twin sparkplugs. So the four cylinder C 230 was replaced by the C 240 (2.4 L) and the I6 C 280 by the V6 C 280. These changes theoretically reduced emissions and fuel consumption without sacrificing power (the C 280 in fact had a slight 4 PS increase with the change).
In the last four years of production the W202 received a few changes in the engine range. In 1998 a less powerful version of the 2.2 L turbodiesel was added, called C 200 CDI, which replaced the C 220 Diesel. In 2000 the C 200 Kompressor T's output was cut to 163 PS (161 hp/120 kW), the C 240 T displacement was enlarged from 2.4 L to 2.6 L, but output remained at 170 PS (168 hp/125 kW) and the C 180 got a 2.0 L engine.
Transmissions: At the launch all W202 variants were equipped with a 5-speed manual gearbox. The 722.4 4-speed automatic transmission, also called 4G-TRONIC, was available as extra cost (standard on the C 36 AMG). In 1996 this old transmission, it was on sale since 1981, was replaced by a 5-speed automatic gearbox (aka 722.5 or 5G-TRONIC), which received the manual shifting in 1999 (722.6). In 2000 the T-Modell, the only still on sale, was equipped with the G56 6-speed manual transmission.
Safety: The W202 confirms the typical attention of the brand to active and passive safety. At the launch the C-Class had standard driver airbag, ABS and integrated side-impact protection; the front passenger airbag became standard from 1994 onwards, and from the same period Traction control (ETS in the 4-cylinder models, combined with limited slip differential (ASD) or ASR in the 6 cylinders models) was available as extra cost. In 1997 ASR became standard in the C 280s equipped with the automatic transmission and in the C 36 AMG, as ETS in the 4-cylinder models, except for the C 180 and the C 220 Diesel.
With the 1997 restyling ASR became standard in all the models, except in the C 180 and C 220 Diesel. This last model continued to offer ETS available as extra cost. Moreover front side airbags and Brake assist (BAS) came in the list of standard safety features. The two basic models finally joined ASR in 1998, and, in 1999, the W202 was the first mid-size sedan to offer ESP as standard in all the range.
Crash Test Ratings: EuroNCAP tested the W202 in 1997 and results were not great: the car obtained only two stars (top score is five) and 16/35 points for the driver and front passenger protection. Pedestrians' safety was better: the W202 scored 2/4. NHTSA tested the C 220 and C 230 models: these always obtained 4/5 stars in the frontal crash. The C 230 was tested also in the side crash: it rated three stars for the front side and four stars for the rear side.
Present Model: DaimlerChrysler introduced a new generation of the C-Class on January 18, 2007 and displayed it in the 2007 Geneva Auto Show. Sales started on March 31, 2007 in almost all European countries. The new vehicle has an extended wheelbase and tracks, a stiffer bodyshell and a design inspired by the most recent S-Class and some hints from the CLS-Class. The model has three levels of equipment - Classic, Elegance and Avantgarde. A high performance AMG version with a 6.2 L engine followed in September 2007, labelled C 63 AMG with 457 PS (335 kW)to rival the Audi RS4 and BMW M3. The Classic and Elegance lines retain the traditional Mercedes-Benz radiator grille, with a three-point star bonnet emblem. The Avantgarde line has a grille similar to that on Mercedes' sport coupe models, with two horizontal bars and a large centre-mounted star. In the UK the Classic line is known as the SE and the Avantgarde line is known as the C-Class Sport , and comes with an AMG bodykit, and AMG alloy wheels as standard. The North American version is slightly different, as the Classic model is dropped. The Elegance is known as the C-Class Luxury and the Avantgarde wearing the AMG sports package is known as the C-Class sport. Both lines have an additional amber light in front of the front wheel well. New saloon and estate versions were announced in 2007, while the Sportcoupé will remain based on the W203 chassis. There will be an increase of component-sharing with other Mercedes' models, namely the redesigned E- and S-Class, as well as the upcoming GLK-Class compact SUV.
Versions of the car are available with a choice of rear- and all-wheel drive (in the latter case an improved version of the 4MATIC system, not available in right-hand drive format), along with a variety of four and six-cylinder engines (and a 6.2 litre V8 in the C 63 AMG). Engines are the straight-4 M271 and V6 M272 petrol engines, straight-4 OM611 + OM651, and V6 OM642 Diesel engines. Six-speed manual transmissions are standard on all models (except the C 350), with the 7G-Tronic seven-gear automatic transmission available for six-cylinder engines (7G-Tronic is available for C 230K, C 280, C 300, C 320 CDI and standard for C 350) and a five speed automatic transmission available for the four cylinder models. In the United States, the C 300 Luxury and C 350 Sport are only available with the 7G-Tronic transmission, and the C 300 Sport comes with a six-speed manual transmission, and the 7G-Tronic automatic transmission as an option.
The development of the W204 C-Class involved the use of a "digital prototype", which put a 2.1 terabyte digital replica of the car through a 15 million mile road course. This is an industry first which allowed for crash testing and more, before a physical prototype was actually constructed.
The C 63 AMG is reportedly the first AMG Mercedes designed from the ground up for performance, as compared to previous AMG cars which were more or less focused on the engine. The C 63 has a revised front end architecture that is taken from the CLK 63 AMG Black series. The revised 7-speed automatic transmission now has three shift modes - Comfort, Sport and Manual - with the last one running with the converter locked allowing the driver to hold the engine at the rev limit. The ESP can now be completely turned off, interfering only under heavy braking. The car also has the quickest, most responsive steering of any Mercedes to date. Car and Driver recently tested the car and got a 0-60 mph time of 3.9 seconds; a 0-100 mph time of 9.2 seconds and a quarter-mile time of 12.3 seconds at 116 mph. The top speed is electronically limited to 151 mph. This makes the C 63 the fastest production 4-door sedan in terms of acceleration.
