About the Mercedes Benz C-Class W203

The Mercedes-Benz C-Class is a compact executive car produced by the Mercedes-Benz division of Daimler AG. First introduced in 1993 as a replacement for the 190 range (W201, also nicknamed “Baby-Benz”), the C-Class was the smallest model in the marque's lineup until the 1997 arrival of the A-Class. The C-Class is built at Mercedes-Benz factories in Sindelfingen and Bremen, Germany as well as in Mercedes's factories in Brazil and Daimler AG's South African factory in East London. The very first W202 C-Class sedan was produced on June 1, 1993, and the second generation W203 C-Class rolled off the assembly line on July 18, 2000. The third generation W204 C-Class was launched in 2007. The C-Class is the entry-level offering in Mercedes-Benz's United States lineup. The C-Class platform has been used for several coupes, including the CLC-Class (and its predecessor, the C-Class Sportcoupe), the E-class Coupe (and its predecessor, the CLK-Class), and again for the 2012 model year with the C-Class coupe.

The second generation C-Class was introduced in 2000. The sedan debuted with a range of straight-four and V6 gasoline engines and straight-four and straight-five Diesels. Most of the engines were carried over from the W202, but the C 320 was exclusive, offering 218 PS (160 kW; 215 hp). The diesels now featured common rail direct injection and variable geometry turbochargers. Six-speed manual gearboxes were now standard for nearly the entire range (except the C 320). For the first time, the number designations were no longer equivalent to the engine displacement, more specifically in the C 200 (1.8 L), C 240 (2.6 L) and C 200 CDI (2.2 L).

In 2001, Mercedes increased the range, with the introduction of the new T-Model station wagon and Sportcoupé. The Sportcoupé was a three-door liftback made to counter the BMW Compact. Removed from the North American lineup in 2005, replaced by the Mercedes-Benz B-Class in Canada, it continued on sale in other markets. From October 2000 until 2007, a total of 230,000 Sportcoupés were built in the Bremen factory and in Brazil. In 2003, a new family of supercharged four-cylinder engines debuted, called M271. All of them used the same 1.8 L engine, with different designations according to horsepower levels, including a version powered by natural gas. The 193 PS (142 kW; 190 hp) C 230 K was initially available only in the Sportcoupé (replacing the 2.3 L engine in 2002 and older models). The newer 1.8 L was less powerful but smoother and more efficient than the older 2.3 L (192 PS (141 kW; 189 hp) compared to 193 PS (142 kW; 190 hp). 4MATIC four-wheel drive versions were also offered for the C 240 and C 320.

The C-Class was refreshed in early 2004. In this year, the interior styling was changed in all three body styles. The instrument cluster was revised to display a set of analog gauges, and the center console and audio systems were revised. A fully integrated iPod connection kit was available as was a better bluetooth phone system made optional. For the USA market C230, the "sport" package was made standard which included AMG edition bumpers, side skirts and front 4 caliper cross-drilled brakes from the C55. Widebody rear suspension with sport tuned springs and dampers completed the package for 2005 Mercedes c180 2005 280 bhp.

Several all-new M272 and OM642 V6 engines were introduced later in the year. The C 230, C 280, C 350 replaced the C 240 and C 320, the new-generation 6-cylinder engines developed substantially more power than the older version, by as much as 24% more, whilst also increasing fuel economy and reducing C02 emissions. The C 230, C 280 and C 350 developed 204 PS (150 kW; 201 hp), 231 PS (170 kW; 228 hp) and 272 PS (200 kW; 268 hp) respectively. The three-valve twin spark design was replaced by a four-valve design, now with variable valve timing. On the diesel side too, things were much improved, with a brand-new V6 3.0-litre CDI diesel. The new V6 diesel offered masses of more power compared to the C 270 CDI, by as much as 32% more, the CO2 emissions and fuel economy were also bettered, the output of this engine 224 PS (165 kW; 221 hp) and its torque of 510 N·m (380 lb·ft) made it the worlds most powerful diesel at the time. The C 220 CDI received a power increase from 143 PS (105 kW; 141 hp) to 150 PS (110 kW; 148 hp) In addition, these engines also received the new seven-speed 7G-Tronic automatic transmission, a more economical naturally aspirated 1.8 L (C 160) was added to the Sportcoupé lineup.

The last W203 C-Class sedan was produced on December 14, 2006 at the Sindelfingen plant. However, the W203 Sportcoupé liftback will continue to be produced in Brazil beyond this date, since Mercedes-Benz does not foresee producing a W204 Sportcoupé. Indeed, it has decided to offer an updated W203-2 or CL203 Sportcoupé with a new restyled front end inspired by the W204 sedan and an improved engine range parallel to the one of the W204. It was also spun off into its own separate line as the CLC-Class.
