The Mercedes-Benz CL-Class is a full-sized grand tourer produced by the German automaker Mercedes-Benz, which stands for Comfort Leicht in German, or Comfort Light in English.

Originally derived from the SL-Class roadster, it has since been based on the S-Class sedan. Known at first as the SEC and later S coupe, it was spun off into its own line and current name in 1998. The CL continues to follow the same development cycle as the S, though riding on a slightly shorter wheelbase and offering smaller selection of engines, mostly tending towards the high-powered of the range.

The closest competitor was the now-discontinued BMW 8 Series coupe. However, while the performance-oriented 8 series had a cramped 2+2 seating arrangement, the rear passenger volume of the CL and its previous incarnations is large enough to classify them as 2-door sedans by the SAE, making the CL one of the few full-sized coupes that offer a combination of engine power and luxury accommodation.

The present generation of the CL-Class, or C216, is currently available in four models: CL500 4Matic (CL550 4Matic in America), CL600, CL63 AMG and CL65 AMG. The 2009 price ranges from $108,775 to $204,575. The most powerful model of the CL is the most expensive Mercedes-branded vehicle (with the exception of the SLR and the S Class Pullman), slightly edging out its equivalent in the flagship S-Class.

W126

The CL-class can most directly trace its roots back to the W126-chassis SEC-class of 1981-1991. The SEC was itself a replacement for the R107 series SLC cars, which were essentially lengthened SL roadsters with a fixed roof and rear seat. The W126 SEC was more directly related to the S-Class sedans. The first generation SEC-Class came in four models: 380 SEC, 420 SEC, 500 SEC and 560 SEC. Like all subsequent models, the rear passenger volume of the SEC coupes was large enough to classify them as 2-door sedans by the SAE.

W140

Main article: Mercedes-Benz W140

The next generation was the sleek, redesigned W140-chassis coupe of 1993-1999. Though the coupe’s physical appearance changed little over these years, the class underwent a name change several times. The V8 and V12 coupes were called the 500 SEC and 600 SEC, respectively, in 1993 only. The 600 SEC was the first V12 coupe ever offered by Mercedes-Benz. From 1994-1997, the model names were changed to the S500 coupe and the S600 coupe. The name "CL" was adopted in 1998, and the W140 coupes were called the CL500 and CL600 from 1998-1999.

W215

Main article: Mercedes-Benz W215

The third generation of the CL is the W215-chassis coupé of 2000 to 2006. It is based on the 1999-2004/5 Mercedes-Benz S-Class, though it rides on an 8-inch (203 mm) shorter wheelbase. It is offered as four models: the V8-powered CL500, the supercharged V8-powered CL55 AMG, the V12-powered CL600 and the rare bi-turbo V12-powered CL65 AMG. The limited-edition V12-powered CL63 AMG was sold in 2001 only. All models seat four.

The CL coupes come equipped with the very latest in Mercedes-Benz technology, and the CL is always the first model to receive new technological features (it introduced the refined Active Body Control fully-active suspension system and Bi-Xenon HID lights).The CL-class has among the most popular luxury coupes in the world, outselling rivals such as the Jaguar XK8 coupe and the Bentley Continental GT.

The CL-class has a lengthy list of available features. The following features come standard: climate control, full air suspension, all-leather interior, wood trim, trip computer, CD, navigation system, front heated seats, power moonroof, as well as power door and trunk closing assist. Optional features include a heated steering wheel and voice-activated telephone, as well as front fan-cooled seats.

Exclusive “designo” packages are also available. These packages add custom color metallic paint, custom color Nappa leather interior and exotic wood trims. They are available in three variants: designo Cashmere, designo Espresso and designo Silver.

In European markets, there was even an optional granite trim that took the place of wood. This was never available in the United States.

In 2003 the cars were upgraded with a newer electronics package that included a DVD-based navigation system instead of the CD-based COMAND system. Also, the engine options changed. The CL55 AMG became supercharged and the V12 CL600 had turbochargers added. Both cars produced 500 hp (370 kW).

Engines

As with all major German manufacturers (except Porsche) Mercedes electronically limits their cars to 250 km/h (155 mph).

The justification for having two models with the same power (CL600 and CL55 AMG) is that the CL55 AMG is sportier and more responsive, while the more expensive CL600 is more luxurious with a smoother ride. The CL65 AMG is made to order in very small numbers, and is the most powerful CL to date.

The CL63 AMG is the rarest W215 CL of all. It was produced only in November 2001, and just 26 examples were ever built for sale. The V12-powered CL63 AMG was only sold in Europe and Asia. Mercedes-Benz never offered the W215 CL63 for sale; all were sold exclusively through AMG with a base price of £110,000 (~US$200,000).

From 1999 through 2002, the V12-equipped cars feature a cylinder deactivation system called Active Cylinder Control. The feature was dropped when the 500 hp (370 kW) bi-turbo V12 was introduced.

C216

Main article: Mercedes-Benz C216

The new model was officially unveiled at the end of June 2006 and was presented at the 2006 Paris Salon. The W216 is offered in four models, the V8-powered CL550 4Matic, the high-performance V8-powered CL63 AMG and the high-end V12-powered CL600 and CL65AMG . The CL500 is sold as the CL550 in North America. The class is based on the chassis of the W221 S-Class and shares similar design cues together with the CLS-Class. The two-door coupe weighs 2185 kg (4817 lb) and like its predecessor, has no B-pillar interrupting the sleek curve of the side windows. The C216 makes use of the Distronic Plus cruise control, which debuted on the 2007 S-Class. This system is able to bring the car to a complete stop, and accelerate again to the pre-set speed, to keep a pre-set distance away from the car ahead of it. This Mercedes-Benz CL has also debuted with the new Active NightVision program that enables drivers to view the conditions in front of the car despite the dark surroundings. As of the 2009 model year, Mercedes-Benz offers the CL550 in only 4Matic, while the CL600, CL63 AMG, and CL65 AMG are in the standard rear-wheel drive.

>>Mercedes-Benz C292

Mercedes-Benz C292

The Mercedes-Benz C292 was a stillborn Group C prototype race car intended for the 1992 World Sportscar Championship season as an evolution of the Mercedes-Benz C291, but never raced due to Mercedes-Benz withdrawing from sportscar racing after a dismal 1991 season.

Built by Sauber for Mercedes-Benz, the C292 featured the same Mercedes-Benz M291 3.5L Flat-12 which had initially disappointed in 1991, but during the offseason continued development and testing and was finally able to produce power similar to Jaguar, Peugeot, and Toyota.

However, given the large amount of money Mercedes-Benz had invested in sportscar racing since their return, while receiving very little returns even after winning two championships and a 24 Hours of Le Mans, the decision was made to cancel the project after only a few C292s had been produced by Sauber. The exact number of C292s that were built is unknown, however one remaining copy is on display in the Sauber museum.

With the cancellation, the C292 was never tested, and therefore its potential in comparison to its competitors was never able to be seen. It is unknown if Mercedes even got to the point of installing the M291 engine in the C292.

This would be the last Mercedes-Benz sportscar until the launch of the CLK-GTR in 1997.

>>Mercedes-Benz C291

Mercedes-Benz C291

The Mercedes-Benz C291 was a Sports-prototype racing car introduced for the 1991 World Sportscar Championship season.

Introduction

The 1991 season marked the introduction of the FIA’s new, and controversial, 3.5 litre formula which replaced the highly successful Group C category that had been used in the World Sportscar Championship since 1982, though due to a small number of entries for the 3.5 litre formula heavily penalised Group C cars (which were subject to weight penalties and started behind the new-style C1 entries on the grid) were allowed participate in the season's C2 category.

To meet the new regulations Mercedes-Benz came up with an all-new car; the C291 which was designed by its racing partner Sauber.

Engine

The primary feature of the new regulations was the use of a 3.5 litre naturally-aspirated engine. This made it impossible for Mercedes-Benz to use the engines from its previous Group C cars. Also, to produce similar power to the Group C cars a 3.5 litre naturally-aspirated engine had to be very high-revving and be constructed from different materials in order to rev highly.

Unlike Jaguar’s XJR-14 who had the readily available and proven Ford HB V8 engine from the Benetton B190B Formula One car (the engine regulations for the new 3.5 litre formula were identical to Formula One), Mercedes-Benz had to design an all-new purpose-built racing engine and its M291 3.5L Flat-12 unit was the result. The engine produced about 650 brake horsepower (480 kW) compared to about 730 brake horsepower (540 kW) produced by 5.0 litre V8 twin turbo found in the C291’s predecessor, the Mercedes-Benz C11.

Design

Unlike the Jaguar XJR-14 the C291 resembled previous sports-prototype, despite the fact that the redesign of the Le Mans Circuit de la Sarthe in 1990 meant cars with their low drag design, top-end power, straight-line acceleration and top-speed characteristics were no longer required. Unlike the Jaguar (and latterly the Peugeot 905B) the Mercedes still featured a full width low-drag single-tier rear wing and no front wing. This resulted in the car having a higher top speed that the Jaguar (and only slightly less than Group C cars) .

However, this, allied to the characteristics of the 3.5 litre engine, meant the car would be less accelerative above 150-170 mph than Group C cars, therefore not taking advantage of the low-drag design, and conversely the low-drag design meant the car was slower in the corners than the Jaguar and Peugeot’s 905B, this time not taking advantage of the lower kerb weight of 750 kilograms (1,653 lb). Overall the C291 was not as fast as a contemporary Formula One car around some circuits used by the Grand Prix fraternity, and was a lot slower at Le Man’s Circuit de la Sarthe in 1991.

Race results

During the development and testing of the new M291 powerplant, it become apparent to Sauber Mercedes that there were problems in the engine design and construction. Thus the team was forced to start the 1991 season with a lone C291, while at the same time running an older C11. Unfortunately, in the first two races of the season, the C291 failed to finish while the C11 managed to finish 2nd and 3rd. By the third race, the C291 was able to finish and score a 2nd place, ahead of the C11. For the fourth round, the 1991 24 Hours of Le Mans, the team decided that the C291 would not be capable of completing the race, and thus were forced to enter three C11s.

After Le Mans, Sauber Mercedes decided that the C291 had been developed enough to compete on its own, and it finished the season without running a C11 alongside. However, the C291 failed to finish the next three races of the season. Only in the final race of the year at Autopolis was the C291 not only able to finish, but also able to score its only win. Sauber Mercedes managed to only finish the season third in the teams championship.

After much disappointment the C291 was planned to be replaced by the more radical C292 for the 1992 season, but unfortunately Mercedes-Benz decided to pull out of sportscar racing before the C292 could compete and turned to Formula 1 in 1993, although it did not continue to use the troublesome M291 powerplant.

>>Mercedes-Benz C112

Mercedes-Benz C112

The Mercedes-Benz C112 was an experimental mid-engined sportscar created in 1991 by Mercedes-Benz as a test bed, similar to the later versions of the Mercedes-Benz C111. Despite using the same number, it was not related to the 1960s Mercedes-Benz W112 series of limousines and coupes of the 1960s. The C112 also was a road-legal counterpart for the Sauber-built Mercedes-Benz C11 Group C prototype race car for the 1990 World Sportscar Championship.

The C112 which also featured gullwing doors was equipped with the new 6.0-litre V12 engine, with the standard 300 kW (408 hp) and peak torque of 580 Nm. The major systems tested on this vehicle were:

Active Body Control

This was designed to control the vehicles stability through a combination of active springs and hydraulics at each wheel, plus sensors that monitor the vehicle’s movements. The vehicles computer assesses the information from the sensors and adjusts the suspension accordingly.

Other systems

The most recent updates in anti-locking braking (ABS) and anti-skid control system (ASR) which split the braking pressure between the front and rear wheels

Active Aerodynamics

This was provided through the cars front spoiler and rear wing which could be moved to ensure the optimum combination of low drag and high downforce. The rear wing was also used to improve the car's braking in emergency situations. Although this was not seen in production until the Mercedes-Benz SLR McLaren.

Even though Mercedes-Benz received 700 orders for the car it never went into production.

>>Mercedes-Benz C11

The Mercedes-Benz C11 was a Group C prototype race car introduced in 1990 for the World Sportscar Championship. Built by Sauber as a successor to the Sauber C9, the C11 used the same Mercedes-Benz M119 5.0L Turbocharged V8 from the C9. It was the first time that Mercedes-Benz chose to put their name on the car, instead of simply using Sauber.

Debuting at the first race of the 1990 World Sportscar Championship season, the car did not actually race, choosing instead to run only in practice while the team used the reliable C9 from the previous year. However, for the 2nd race the C11 did race, and was able to successfully come home with first and second. Throughout the rest of the season, the C11 won all but one race and easily took the team's championship for the year.

Although Sauber-Mercedes had been successful in winning the 1989 24 Hours of Le Mans, the team choose not to defend the title in 1990 due to the race not being part of the World Sportscar Championship schedule. The team chose instead to concentrate on winning the championship.

Although the C11 was to be replaced by the Mercedes-Benz C291 for the 1991 World Sportscar Championship season, problems with the C291's new engine led Mercedes-Benz to continue to campaign the C11 alongside the C291. The C11 was able to gain three more class wins in the 1991 season before the C291 fully replaced it.

It should be noted that the reason that Sauber skipped from C9 to C11 is due to the difficult pronunciation of C10 in German, with C and 10 being pronounced nearly identically.

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, the C-Class was nicknamed the "Baby Benz" as it 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 and DaimlerChrysler'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 platform has been used for several coupes, including the CLC-Class (and its predecessor, the C-Class Sportcoupe) and CLK-Class.

The first generation W202 C-Class was introduced in 1993, as a replacement for the Mercedes-Benz W201 (190), and proved successful among high-end car buyers. 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.

Engines

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 lb·ft). . 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 Portuguese 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 improved 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 - which 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.

T-Model

W202 T-Model

In the 1980s the Mercedes-Benz 190 suffered from the lack of an estate version, which was available in the range of competitors BMW 5 Series and Audi 80. Mercedes-Benz finally introduced an estate model in 1996, called T-Modell (T for Touring or Transporter). It shared the same versions of the sedan, with the exception of the AMG versions.

US-spec models

W202s exported in North American market included the C 220 (later replaced by the C 230), 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.

Restyling

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.

AMG

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. The 3.6 L engine had a maximum output of 280 PS (276 hp/206 kW) at 5750 rpm and 385 N·m (284 lb·ft) at 4000 rpm. Top speed was electronically limited to 250 km/h (155 mph). Only 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 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 lb·ft) at 3250 rpm. It was also available as a station wagon. Again, only 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.

There was also a very rare AMG C55 version of the W202 C Class, of which fewer than 100 cars were produced. This version used the 5.5 litre V8 engine from the E55 AMG.

W203-2 CLC-Class

The second generation C-Class was introduced in 2001, with a sportier look than the previous generations, with a steeper front-end and shorter rear-end. The styling cues were similar to that of the W220 S-Class. 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), also the C240 now had 2597 cc but output was unchanged at 170 PS (125 kW/168 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 C320 and C 270 CDI). For the first time, the number designations were no longer equivalent to the engine displacement, more specifically in the C 180 (2.0 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-Modell station wagon and Sportcoupé. The Sportcoupé was a three-door liftback made to counter the BMW Compact, but like its competitor, it proved unpopular with the younger buyers it was targeted towards, due to high prices compared to the lower entry-level models it was competing against, and unfavorable exchange rates. Although removed from the North American lineup in 2005, 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 Canada, it was replaced by the Mercedes-Benz B-Class. In 2003 new family of supercharged four cylinder engines, dubbed M271, also debuted. 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 230K 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. Different taillights were added to the Sportcoupé and several all-new M272 and OM642 V6 engines were introduced later in the year. These were available in both petrol and diesel configuration, ranging between 2.5 L and 3.5 L, and the three-valve twin spark design was replaced by the more standard four-valve design, now with variable valve timing. The C 350 could now reach 272 PS (200 kW/268 hp), while the C 320 CDI was good for 224 PS (165 kW/221 hp). In addition, these engines also received the new seven-speed 7G-Tronic automatic transmission as optional, the diesel four cylinder's power was slightly increased, and a more economical naturally-aspirated 1.8 L (C 160) was added to the Sportcoupé lineup.

The C-Class is arguably one of the highest performing automobiles in its class in many of the European markets. In 2002 it achieved success in the field of safety by scoring the maximum five stars in a EuroNCAP crash test.

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.

AMG models

After the performance of the AMG models in the previous generation, Mercedes-Benz attempted to increase sales among high-end buyers by introducing two different AMG versions in the new model, also in 2001. The C 32 AMG scaled back down to a 3.2 L V6 engine, to match the E46 M3 displacement and improve weight distribution, but it required a twin-screw type supercharger (manufactured by IHI) to reach 354 PS (260 kW/349 hp)) at 6100 rpm and 450 N·m (332 lb·ft) at 4400 rpm. Like its predecessors, it used a five-speed automatic, helping it to complete a 0-100km/h sprint within 5.2 seconds. The second version was C 30 CDI AMG, using a 3.0 L five-cylinder engine, capable of 231 PS (170 kW/228 hp) at 3800 rpm and 540 N·m (398 lb·ft) at 2000 rpm. Both were available in all three body styles, but the diesel model did not reach sales expectations and was retired in 2004, as well as the C 32 AMG Sportcoupé.

By the revision of the C-Class in 2005, C 32 AMG was also replaced, giving way to a new 5.5 L naturally-aspirated V8-powered C 55 AMG. This was an evolution of the V8 engine found in the previous E-Class, with power raised to 367 PS (270 kW/362 hp) at 5750 rpm and torque climbing to 510 N·m (376 lb·ft) at 4000 rpm. Unlike the less-powerful V6s and V8s in the rest of the Mercedes-Benz lineup, it continues to use Speedshift five-speed automatic. Though maximum speed is still limited to 250 km/h (155 mph) and 4.9 seconds from 0 to 100 km/h (62 mph) is improved, this model is considered the sportiest AMG model in the C-Class history before the recent release of the W204 (third generation) C63 AMG.

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 four trim levels of equipment - Classic, Elegance, Avantgarde, and AMG. 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. In the United States, the Classic is not sold, while 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. In Canada, only the Avantgarde and AMG models are sold, with the Avantgarde line simply labelled as the C-Class.

One of the most technological breakthroughs of this car is a special system exclusive to this class, named 'Agility control' package. This is an innovative system, which through its unique concept provides drivers with excellent agility and the traditional, luxurious Mercedes ride quality. It achieves this feat through a complex hydro-mechanical set up, which constantly analyses road conditions and driving 'habits', resultantly it adjusts damper & suspension settings accordingly to provide the driver the best possible balance between ride comfort and agility. To take things still further , there is even an 'Advanced agility control' package drivers can opt for, this system is an upgrade to the standard one, offering a 'sport' mode button. The 'Advanced agility' package is a first for the C-class, and will be seen in future models, as the GLK.

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. Most of the engines are from the W203 C-class, but the C180K, C200K, C200 CDI & C220 CDI derivatives are new offering power outputs of 156hp, 184hp, 136hp & 170hp respectively, also with improvements with respect to emissions and fuel consumption. In 2008 new generation V6's are expected to replace the current V6 powerplants. Six-speed manual transmissions are standard on all models (except the C 350),(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. In Canada, 7G-Tronic automatic transmission comes with any 4MATIC model.

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 tested the car in their December 2007 issue and got a 0-60 mph time of 3.9 seconds and a quarter-mile time of 12.3 seconds at 116 mph (187 km/h). This makes the C 63 one of the fastest production 4-door sedans in the world.

In 2004, C-Class DTM debuted for the first time.

Concepts

Siemens employing prototype hybrid technology, showed off a modified Mercedes C-Class Sport Coupe that boasts faster acceleration, more torque -- and better fuel economy -- than its gasoline-powered equivalent. However, the company admitted that the car was "far from ready for production", and too expensive to manufacture or sell.

The Mercedes-Benz Bionic was a concept car created by DaimlerChrysler AG under the Mercedes Group. It was first introduced at DaimlerChrysler Innovation Symposium in Washington. The bionic was modelled after a type of fish, the Ostracion cubicus (a boxfish), and also has 80% lower nitrogen oxide emissions with its SCR technology.

Engine and Performance

The Bionic is powered by a 103 kW direct-injection diesel engine that gives out around 70 MPG (~3.36 L/100 km). This engine also gives out around a total of 140 horsepower (100 kW) and a little over 221 ft·lbf (300 N·m) of torque at around 1600 rpm. The Bionic can go from 0-60 in about 8 seconds and has a top speed of a little over 190 km/h (118 mph) .

Design

The exterior design was modelled after the yellow boxfish (Ostracion cubicus), a tropical fish that lives in coral reefs. Mercedes-Benz decided to model the Bionic after this fish due to the low coefficient of drag of its body shape and the rigidity of its exoskeleton; this influenced the car's unusual looks. Other parts of the design include the fact that the rear wheels are partially fitted with plastic and that it's considered as a lightweight vehicle. Mercedes-Benz reported a drag coefficient of 0.19; for comparison, the production vehicle with the lowest ever Cd value was the GM EV1, at 0.195, and this had a much smaller internal volume than the Bionic.
