The Mercedes 2008 C230 Sport Sedan with the AMG Sport Package exterior side angle view closer - White
The Mercedes-Benz C-Class is a luxury compact car produced by the Mercedes Car Group division of Daimler AG. First introduced in 1993 as a replacement for the 190 range, the C-Class was the most affordable 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 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.

Mercedes-Benz F700 Concept
On starting and at full load, the air-fuel mixture is not ignited by a sparkplug as in a conventional gasoline engine. The controlled auto ignition (homogeneous combustion) to which the DIESOTTO automatically reverts within its working cycle occurs under partial load conditions, i.e. at low and medium engine speeds.
As a result of homogeneous combustion at reduced reaction temperatures, very low emissions of nitrogen oxides are produced. The rest of the emission control work in the DIESOTTO drive is handled by a standard three-way catalytic converter. In addition, in order to combine the individual subsystems into one drive concept, a highly efficient engine management and control system has been implemented.
The drive unit of the F 700 is a compact four-cylinder with a displacement of 1.8 liters, and yet it ensures that feeling of effortless, superior power afforded by a luxury sedan: a two-stage turbocharger system ensures good response and torquey pulling power. In addition, when the car moves off the internal combustion engine is assisted by the electric motor of the hybrid module. The maximum output is 175 kW (238 hp), the electric motor pitches in another 15 kW (20 hp), and the system�s maximum torque is about 400 Newton meters. The 0 to 100 km/h (62 mph) sprint time of 7.5 seconds attests to the dynamics of the F 700, whose top speed is limited to 200 km/h. Despite these outstanding performance figures, the consumption of the F 700 in the standard cycle is only about 5.3 liters, equivalent to CO2 emissions of 127 grams per kilometer � extremely low for an automobile of this category.
Anticipatory intelligence packed into the suspension
Similar advances are made by the F 700 in the area of ride comfort. Mercedes-Benz has always been a leader in the area of road roar/tire vibration characteristics and suspension comfort: the Active Body Control suspension system in the CL-Class, S- and SL-Class sets the standard worldwide with its unrivaled combination of comfort, handling safety and dynamics. This system is now surpassed by the new technology of the F 700.
For here, once again, the new research car takes an important step to the future: thanks to its active PRE-SCAN suspension, the vehicle not only responds with great sensitivity to roadway unevenness; more than that, it acts with foresight.
PRE-SCAN uses two laser sensors in the front headlamp units as �eyes�. They deliver a precise image of the condition of the roadway. Based on the image supplied by the laser sensors and the information on the vehicle state, the control unit figures out a specific strategy which the high-pressure hydraulics translate into precisely calculated fluid flows and pressures for each single wheel.

Mercedes SLR
The McLaren Mercedes-Benz SLR is inspired by the Mercedes-Benz 300 SLR of 1955 which was actually based on the W196 F1 car, yet named after the road-going 300SL Gullwing.
The McLaren Mercedes-Benz SLR is a Anglo-German supercar jointly developed by Mercedes-Benz and McLaren Automotive. Built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England. Daimler AG, owner of Mercedes-Benz, also owns 40% of the McLaren Group.
Classified as a supercar and compared to cars like the Porsche Carrera GT and Enzo Ferrari, the presence of the automatic gear box, front mid-engined arrangement and its driving characteristics lead some commentators to classify the SLR McLaren as a Super GT whose closer rivals are the Aston Martin V12 Vanquish and Ferrari 599 GTB. One of the goals of the SLR was to combine both supercar and GT characteristics.
The SLR sports a 232-kilogram (511.8 lb), hand-built, 5.4-litre (5439 cc/331.9 cu in), supercharged, all-aluminum, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 milimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The Lysholm-type twin-screw supercharger produces 0.9 bar (13 psi) of boost, the turbine rotates at 23000 revolutions per minute, and the air is cooled via two intercoolers. The engine generates a maximum power of 626 PS (617 hp/460 kW) at 6500 revolutions per minute and a maximum torque of 780 newton-metre (575 ft�lbf) at 3250 revolutions per minute.
Unlike most of its contemporaries, its engine is front-mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metre behind the front bumper, and around 50 cm behind the front axle. They also optimized the design of the center firewall.

Mercedes pace car
In motorsport, a safety car or pace car is a car which limits the speed of competing cars on a racetrack in the case of a caution period such as a major accident or obstruction on the track. During a caution period the safety car enters the track ahead of the leader. With few exceptions, competitors are not allowed to pass the safety car or other competitors during a caution period, and the safety car leads the field at a pre-determined safe speed, which may vary by series and circuit. At the end of the caution period, the safety car leaves the track and the competitors may resume racing.
In production automobiles, a safety car is one which highlights safety features (see automobile safety).
