Mercedes Benz C-class W202 Development

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.
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. Due to Italian and Portugese car tax rules, 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 (co-developed with Bosch). 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).
W202s exported in North American market included the C 220 (later replaced by the C 230 and C 240), C 280 (both I6 and V6) and the AMG variants. It was launched in the U.S. in 1994 and differed from Euro-spec models due to a third stop light, no specific trim levels and side lights at the end of the front turn signals.
In 1997, the C-Class was given a small midlife freshening, with new darker rear lights and new wheel rims as well as subtle interior trim changes, especially the door mouldings. Front and rear bumpers also changed in shape for a more modern, even sporty, look.
In 1995, the C-Class received its first genuine performance model, the C 36 AMG, to counter the new six-cylinder BMW M3. Developed with AMG, the tuning house that had now become a subsidiary of Daimler-Benz, it had a racing-tuned suspension (lowered by 25 mm (1 in)) and in the USA, a four-speed automatic gearbox, followed by a standard five-speed automatic gearbox with Tiptronic function in 1996. The 3.6 L engine had a maximum output of 280 PS (276 hp/206 kW) at 5750 rpm and 385 N•m (284 ft•lbf) at 4000 rpm. Top speed was electronically limited to 250 km/h (155 mph). A total of 5200 C 36 AMGs were produced.
In 1998 AMG developed a new flagship for the C-Class, the C 43 AMG, powered by a smoother 4.3 L V8, which could now achieve 306 PS (302 hp/225 kW) at 5850 rpm, with a torque of 410 N•m (302 ft•lbf) at 3250 rpm. It was also available as a station wagon. 4200 AMG units were produced, with only 25 C 43 vehicles of the 2000 model year imported to the US. This vehicle bears four gear assembly each side by side to impart better fuel efficiency & performance.
