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.

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.

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.

Related Mercedes-Benz A-Class

The Mercedes-Benz B-Class (codename W245) is a compact MPV introduced by German automaker Mercedes-Benz in March 2005. It is essentially an enlarged A-Class keeping the same engine and suspension system. Like the A-Class, the B-Class is a front wheel drive vehicle.

Mercedes-Benz describes this vehicle as a Compact Sports Tourer instead of hatchback or multi-purpose vehicle, like its R-Class model, which is called a Grand Sports Tourer.

It was released in Europe in the late spring of 2005 and in Canada in the autumn of 2005. Plans to import the car to the US through Mexico were put on hold due to a strong euro.

Design

Keeping in mind its United States' market in comparison with the A-Class and indeed emulating the R-Class, the aspect of the B-Class was stylized from the back to the nose. Some of the tiny stylistic details of the Baby-Benz (popular name of the A-Class) were removed. In particular, the front of the vehicle was lengthened (although maintaining the Sandwich anti-crash system).

Sandwich floor concept

The B-Class W245 maintains the sandwich floor concept.

The powertrain (engine and transmission) moves beneath the passenger cell (located at high seating position) in the event of a big frontal impact. According to a study : "the front section of the A-Class would have to be considerably longer in order to offer the same impressive level of occupant safety in the event of a heavy frontal impact".

These are two innovations, patented by Mercedes-Benz as:

  1. DE 43 26 396 C 2: motor car with drive unit tilted at an acute angle against the horizontal
  2. DE 44 00 132 C1: Firewall construction for a motor car with front-mounted drive unit

As a secondary benefit, because the seats have been raised by 20 cm, the passengers are taken away from the more common area of lateral impact in accidents.

Driving assistants

Pre-facelift B-Class 170

The B-Class presents a wide interior, basically due to the Sandwich floor.

The multifunction steering wheel (standard feature) allows the driver to use his/her thumbs to control the radio, telephone and other systems. There are power assisted steering (standard feature) aids in the control of the automobile, varying according to the speed.

The COMAND APS is a system where Route instructions are given to the navigation system, and the information is provided via SMS. The car radio, DVD and telephone controls are combined into a single unit with a 6.5 inch screen. The options are: standard Audio 20 radio/single CD, Audio 50 APS or COMAND APS.

Parktronic emits warning tones and uses multiple LEDs to indicate how far the car is from an obstacle.

W245 defines the Light & Sight package with several benefits:

  • Bi-xenon HID headlamps (optional feature) with gas-discharge bulbs for the dipped beam
  • Cornering lights (standard feature) where the main-beam dips at road junctions and tight corners
  • Active light system (standard feature) where the beams follows the steering movements
  • Headlamp Assist (standard feature) is a sensor on the windscreen monitoring ambient light levels to automatically switch on the headlamps as required
  • Rain sensor (standard feature) smoothly adjusts the wiper speed, depending on the intensity of the rainfall.

As a standard addition, when entering a tunnel or an underground garage, the Tunnel Mode closes all windows and the panoramic sliding sunroof.

Inside comfort

The multicontour seat (optional feature) is composed of a set of small air cushions individually adjusted to the driver's body, as he/she wishes.

Air conditioning

The W245 units have a powerful car air conditioning system, with separate temperature adjustment for driver and front passenger.

Standard CDI models include a Heater Booster System (standard on CDI models) that instantly floods the interior of the B-Class with hot air. The most advanced system is the Thermotronic (optional feature) that maintains and regulates the temperature in accordance with a sophisticated set of sensors which measure temperature, sunlight, humidity and even pollutant levels in the ambient air, causing all openings to close automatically.

Sunroof

The new optional sunroof is divided in small panels that can be displaced individually. Each one can be controlled separately to selectively administer the shades inside the W245.

Safety

High-strength and ultra-high-strength steel alloys are combined with high-strength bonded joints.

Airbags

The B-Class has several airbags. The front airbag is adaptive with two-stage gas generators (standard feature), where the system evaluates the severity of the accident. The B-Class also includes side airbags for head and thorax (standard for driver and front passenger).

Two other additions are optional: Rear Sidebags (optional feature) for side-on collisions in the back seats and Windowbags: large airbags expanding like a curtain from A- to C-pillars in side-on collisions.

Belts

The belt system of the B-Class W245 is simply surprising. The Adaptive Function (standard feature for driver and front passenger) adapts the force exerted by the belt, relaxing dynamically during the collision. On the contrary, the Tensioners (standard feature) continuously adjust to remove any possible slack, and increase the tightness if necessary. The driver has a report if all the belts are buckled (standard feature).

Head and neck

Lastly, the active head restraints (standard feature) respond actively to a collision, assuring even more protection.

Other standard features

While driving there is the Acceleration-Skid Control (ASR) (standard feature) and Electronic Stability Program ESP (standard feature) that reduce the risk of skidding. There are disc brakes on all four wheels, and emergency stops are improved with the Anti-lock braking system (ABS) and Brake Assist (BAS), standard on the Mercedes Benz A-Class. BAS detects emergency braking (most drivers apply the brakes quickly but without enough pressure) and exerts maximum brake pressure.

Making room

To make more room for transporting goods, it is possible to fold the seats forward and then level them at two different heights. They provide different final modular space combinations.

Its implementation is provided by two systems:

  1. Easy-Vario: Both rear-seat cushion sections are folded forward, while the luggage compartment floor can be set to one of two different heights. (Optional feature)
  2. Easy-Vario-Plus: Both rear-seat cushion and the front passenger seat are folded forward. This increases the load capacity to as much as 1995 litres. (Optional feature)

Engines

The Mercedes Benz B-Class W245 has six engines: four of them are petrol (B150, B170, B200, B200Turbo), and two are diesel (B180 CDI, B200 CDI). All the six powerplants are four-cylinder.

The B200 Turbo reaches 193 hp and 280 Nm of torque. It sprints from standstill to 100 km/h (60 mph) in 7.6 seconds, and has a top speed of 230 km/h (140 mph).

The B200 CDI reaches 140 hp and 300 Nm of torque. The newly developed direct-injection CDI diesel units have a common-rail direct injection (standard on CDI models).

All the engines meet the Euro IV emissions regulation, and a particulate filter system is available as an option for the diesel units (this reduces about 99% of the particle emissions, without the need for additives).

Gearboxes

The B-Class is available with five and six-speed manual transmissions. The six-speed gearbox is the standard on B180 CDI, B200 CDI and B200 Turbo.

As an option there is an Autotronic Continuously Variable Transmission (CVT) in which the ratios are changed continuously by means of a pulley-wheel variator and a steel thrust belt. This allows the car to accelerate with no interruption of tractive power and attains the maximum output more quickly. This is adjustable according to driving style: economical or sporty.

Wheel axles

The B-Class is a front-wheel drive car.

In the W245 the dynamic handling was powered in precision tracking and anti-roll support, with the Parabolic Rear Axle (standard feature) that grants a pivotal role in the driving. The car has a Selective Damping System (standard feature), where the shock absorber forces are administered differentially, in example under normal conditions (soft absorption) and while cornering at speed (full damping force).

The W245 presents light alloy wheels. With the run-flat feature (continuous mobility or zero-pressure tyres can be driven at normal speeds). There is Tirefit tyre sealant and a tire-pressure-loss warning device by ESP technology (standard feature).

2008 B-Class facelift

2008 Mercedes-Benz B-Class (North America)

Mercedes-Benz has recently released a refreshed-look B-Class alongside a refreshed-look A-Class and M-Class.

The newer B-Class has a restyled hood, front bumper, rear tail lamps, side exterior mirrors and is now available in the B170 NGT Blue Efficient. The B170 NGT Blue Efficient can run on either gas or petrol, and when full, can cover up to 1,000 kilometres (620 mi).

The new B-Class is now available with new upholsteries and trims.

Mercedes-Benz Axor

A 2005 model Mercedes Benz Axor in Exeter

The Axor is a truck manufactured by Mercedes-Benz designed to fill the gap between the premium Actros tractors and the mostly rigid Atego trucks and was targeted at fleet customers.

The truck is relatively simple, with manual gearshift as opposed to the electronic paddle shift on the Actros. The Axor is powered by a 12 litre straight 6 engine.

2005

Originally the Axor was only available as a tractor but with the 2005 facelift, former Atego models over 18t are now part of the Axor Range.

>>Mercedes-Benz Atego

Mercedes-Benz Atego

Mercedes Benz Atego

The Mercedes-Benz Atego is a light rigid truck introduced by Mercedes-Benz in 1997.

It is available in weights of 7.5 to 26 metric tonnes (t) and is powered by a straight 4 or 6 cylinder engine. Originally all straight engined rigids by Mercedes were marketed as Atego but from the 2005 facelift Atego models over 18 t were renamed Mercedes-Benz Axor.

The designation is 970.

Race versions of the trucks are simply called Mercedes-Benz Race Truck, built by LARAG in the East Swiss canton St. Gallen. The race trucks have competed in ADAC Truck Grand Prix and NRW Truck Cup.

Electric version

The company is conducting large-scale fleet tests with the Mercedes-Benz Atego BlueTec Hybrid delivery truck of 7.5 and 12 tons GVW, used to deliver mail in Germany.

>>Mercedes-Benz Actros

Mercedes-Benz Actros

A Mercedes-Benz Actros truck in Poland
Mercedes-Benz Actros

The Mercedes-Benz Actros is a heavy duty truck introduced by Mercedes-Benz in 1996. It is normally used for long-distance haulage, heavy duty distribution haulage and construction haulage. It is available in weights of 18 to 250 tonnes and is powered by a V6 or V8 cylinder engine with turbo and intercooler. Mercedes-Benz launched Actros II in 2002.

Gearbox

The second Actros generation comes with an electronic sequential gearbox that Mercedes-Benz has dubbed the "Telligent Gearbox". It pushes forward the principle used in some earlier Mercedes-Benz tractors -- using the gearshift lever to command a pneumatically actuated system that changes the gears. The Telligent gearbox utilizes a computer, together with a load-sensing system on the fifth-wheel coupling, to estimate the proper gear that the truck must be in. For example, if you want to upshift, the computer estimates the load on the tractor and the current engine mode, and gives you the proper gear for decreasing engine RPM. On the other hand, if you want to downshift, the computer assumes you wish to overtake, and gives you a proper gear for acceleration.

There's an automatic version, which works like the Tiptronic system found in Mercedes-Benz cars.

Operation

The system consists of a small lever mounted under the right armrest and a flat switch underneath. The lever is slightly tilted, so that it matches the natural curve of the driver's hand when it's on teh armrest. The lever has two buttons on either side. When at a standstill, the driver must push the left button, then (while holding it), push the lever forward and release it. This always selects second fast. Then the driver could push the lever forward once again to select fourth fast. The current gear is shown as a large number on the main display. After doing this, the driver steps on the clutch pedal and waits for approximately two seconds. After the gearshift has completed, a double click is sounded through the speakers, and the driver proceeds with pulling off as normal.

Once moving, the driver has two choices. He or she may push or pull the lever to let the computer choose the gear for them, or they can use the splitter switch (the small switch under the lever) to pre-select gears. Either way, the gear is selected first, then the clutch is depressed. For example, if you're in fourth fast, pulling the splitter switch up once pre-selects fifth slow.

The right button (known as the 'flush button', as it is flush with the lever) is used to switch to neutral.

Advantages

Since the driver does not directly operate on the gearbox, it significantly reduces the wear and tear on the gearbox itself. The gearbox is fully synchronized, and in some models the computer would even blip the throttle for you for a smoother downshift. Also, it's great for novice drivers, who are not sure of the proper gear.

Drawbacks

The computer rarely estimates the steepness of the road. When driving on extremely steep roads, or under winter conditions, it's better to use the manual pre-selection (by using the splitter switch) instead of letting the computer do the job.

Also, the Actros has been designed as a highway tractor. However, even highway tractors have to drive through cities at times. The two-second delay could be very unpleasant when having to pull out of a stoplight. Also, this two-second delay is practically dangerous when overtaking. A driver would slam their manually-controlled gearbox in a lower gear for less than a second, in order to get acceleration. Whereas failing to do this at a stoplight simply slows down other traffic, when overtaking it could leave you in the opposite lane with no power.

Another safety consideration is the situation when the brakes and/or retarder have failed during a long descend. With a manually-controlled gearbox the driver would be able to downshift no matter the grinding, whereas the Telligent would not allow the downshift, thus leaving the truck coasting down.

Also, in an automatic version overtaking is nearly impossible, as the gearbox switches up as soon as the engine goes past the redline, thus slowing down acceleration.

Cab

The cab of the Actros is built with consideration of the driver. It provides silent, smooth and pleasant ride. Pneumatic suspension of both the cab and the tractor itself makes for a really smooth feeling even on the roughest road. The high-roof sleeper version provides two bunks (the upper one not usable while driving, as the seats must be folded). The upper bunk is somewhat wider, but all the controls (radio, windows, auxiliary heater, etc.) are available from the lower bunk. However, most of the controls one would need (auxiliary heater, sunroof, etc.) while resting doubled overhead of the driver, and the width of the upper bunk allows for a person to use them by merely stretching their hand.

The auxiliary heater can be programmed to turn on, for example, 30 minutes before the driver enters the truck, so in the winter a driver would be able to enter a warm cab instead of waiting for it to warm up.

There are large storage spaces, especially in the MegaSpace cab. Additional storage spaces are available under the lower bunk. In some cab types there are boxes behind the doors, that open from the inside, but are accessible on the outside - for storing tools, lashing belts, ratchets, etc.

The driver seat is a fully adjustable Grammer pneumatically suspended seat, and the passenger seat only allows for backrest adjustment. The steering wheel is fully adjustable as well, and allows the driver to control functions of the on-board computer as well as the built-in radio/CD player.

The cab has excellent sound isolation and provides almost car-like noise-levels.

The Actros cabs come in three types:

  • S - designed for daily operation and construction vehicles such as cement trucks. The daily cab has its front bumper lower to the ground to prevent under-run, whereas the construction version of the S cab has its front bumper higher to prevent hitting an obstacle when driving off-road on the site.
  • M - designed for distribution vehicles. It offers a sleeper, though comfort has not been focused on as in the L cab. It comes in short and long sleeper versions.
  • L - Low-roof long-haul cab, providing comfortable driving and rest for the driver.
  • LH "MegaSpace"- Long-haul high-roof cab, providing comfort for long driving, as well as enough space for the driver and/or passenger to freely move around the cab when needed.

Electronics

The Actros comes with ASR and ABS as a standard. Also, it has load-sensing compatibility with most of the modern trailers. On the versions equipped with a digital tachograph, basic information (like current driver's working hours) are displayed on the main display. The computer's interface is very intuitive, and it is fully controllable from the steering wheel.

There is a wide range of other electronic features, offered as extras. These include lane assist (warns the driver if they inadvertently leave their lane), distance measuring radar (which engages the brakes if the vehicle in front suddenly stops), side looking radar for warning the driver about a vehicle in their blind spot, and many more, mostly oriented towards safety. All of them are marketed as "Telligent".

Problems with electronics

In some cases, when the electronics of the trailer (especially the ABS sensors in the wheels) get wet, the brake pedal would not operate as normal, and even the slightest touch would result in a wheel-lock. There are problems with the calculation of the mileage available for the remaining fuel. Cases have been reported when the fuel has run out with the computer showing 25 more miles to go. Also, the statistics of average speed and fuel consumption are prone to failure when driving a digital tachograph truck without a driver card.

Variants

Actros Armoured Heavy Support Vehicle System (AHSVS) is a military armoured truck (86 ordered by Canadian Forces Land Force Command in 2007) using the civilian Actros platform with a protected cab developed by Land Mobility Technologies in South Africa for Mercedes-Benz.
