S 350 BlueTEC (W 221)

Enhanced efficiency, safety and luxury

Mercedes-Benz is now combining the V6 diesel engine in the S 350 BlueTEC with an ECO start/stop function. As a result, the fuel consumption of the luxury class saloon has been brought down to 6.2 l/100 km (37.93 mpg/US, 16.12 km/l) (NEDC combined). The S 350 BlueTEC is also one of the world’s cleanest diesel models.

The V6 diesel engine in the S 350 BlueTEC develops an output of 190 kW (258 hp) from a displacement of 2987 cc, and generates 620 Nm (457 lb-ft) of torque . It also comes with excellent fuel consumption and emission values as standard. Thanks to BlueTEC with AdBlue®exhaust treatment, the S-Class model – which made its debut in 2010 – currently already fulfils the emission values planned for 2014 in accordance with the EU6 standard, and as such is one of the world’s cleanest diesel vehicles. The new ECO start/stop function fitted as standard now helps to improve the efficiency of the luxury class saloon even further. With a combined consumption of 6.2 l/100 km (37.93 mpg/US, 16.12 km/l), the S 350 BlueTEC improves on the figures of its predecessor by 0.6 litre, or nine percent. CO2 emissions have dropped from 177 to 164 grammes per kilometre.

The ECO start/stop system developed by Mercedes-Benz switches the engine off when the vehicle comes to a standstill – for example at traffic lights. The engine then immediately starts again as soon as the driver takes his foot off the brake pedal. Thanks to the intelligent control system, all of the vehicle’s functions and comfort systems continue to operate during the stop phase.

The increase in efficiency was also achieved, among other things, through the use of TWAS (twin-wire-arc-sprayed) coating technology.

AMG has been using TWAS coating technology since 2005 in the 6.3-litre V8 in all model series, including the new SLS. Based on the positive experiences gained, Mercedes has now also developed this technology further for diesel engines. It is currently being introduced in the new Mercedes V6 diesel engine.

The benefits are impressive. Taking the diesel engine as an example, the potential savings are around 3%. At the same time, the weight has been reduced by 4.3 kg.

BlueTEC is a technology developed by Mercedes-Benz to reduce emissions from diesel vehicles, in particular nitrogen oxides. To this end AdBlue®, an aqueous urea solution, is injected into the exhaust flow. This releases ammonia, which converts up to 80 percent of nitrogen oxides into harmless nitrogen and water in the downstream SCR (Selective Catalytic Reduction) catalytic converter. As a result, the S 350 BlueTEC already complies with the emission levels which are planned for 2014 with the introduction of the EU 6 standard. The AdBlue® tank is installed under the luggage compartment floor and has a capacity of 25.7 litres (6.78 US gallons). The tank is replenished at the regular maintenance intervals every 25,000 kilometres.

Active Lane Keeping Assist and Active Blind Spot Assist

In parallel with the CL-Class, Mercedes-Benz is also introducing two new safety systems for the S-Class which can help to avoid dangerous situations and accidents. When the wheels pass over a broken lane marking, the system activates an electric motor in the steering wheel which triggers brief vibrations – a subtle but effective warning signal. Active Lane Keeping Assist takes effect when the vehicle unintentionally passes over a continuous line to the right or left of the lane. In this case it gently brakes the rear wheel on the opposite side of the vehicle to counteract the drift away from the lane. Active Lane Keeping Assist employs the ESP® electronic stability programme for this purpose.

Active Blind Spot Assist is now available as a further new feature for the S-Class. This system warns the driver by means of a red signal in the glass of the exterior mirror when it detects that changing the lane may lead to an accident. Close-range radar sensors scan the area directly alongside and behind the car for this purpose. If the driver ignores the warnings and a vehicle in the neighbouring lane comes dangerously near – when cutting in after overtaking, for example – gentle corrective braking intervention will take place via ESP® on the wheels on the opposite side of the vehicle. This results in slight yawing of the saloon around its vertical axis as a result of the varying brake force distribution. Where an accident is nevertheless unavoidable, braking intervention by Active Blind Spot Assist helps to reduce the severity of impact. Active Lane Keeping Assist and Active Blind Spot Assist are available for the S-Class now as part of the Driving Assistance package PLUS.

New leather appointments with stitching

To personalise the interior of the S-Class, Mercedes-Benz is also offering new, high-quality leather appointments which underscore the luxury saloon’s exclusive character. A defining feature is the contrasting stitching on the PASSION leather package and the Exclusive PASSION leather package (standard for S 600). Colours and scope of appointments vary according to upholstery and package contents.

The PASSION leather package features the stitching on the fine leather of the seats and armrests as well as on the top and bottom of the instrument panel support and the door panelling, all of which are finished in ARTICO, a man-made leather which is pleasant to the touch. The Exclusive PASSION leather package features seats, armrests, instrument panel support, door linings, ruffled pockets and a rear shelf in fine leather with contrasting stitching. Alcantara is used for the roof liner and to cover the A-, B- and C-pillars.

Tailor-made high-end sound system

Bang & Olufsen BeoSound AMG Soundsystem

The new Bang & Olufsen BeoSound AMG sound system tailored to the luxury saloon’s interior is available as a further new feature for the S-Class (standard for S 65 AMG). A combination of 15 loudspeakers and two amplifiers with a total output of 1200 W ensure a thrilling quality of sound from this high-end system. The algorithm of the digital sound processor allows a choice between high-end studio sound and surround sound, and the audio output can be focused exactly on the seat positions of the driver, front-passenger, rear seats or the centre of the interior. Music can be enjoyed on long trips without tiring the listeners, thanks in particular to the dynamic compensation of driving noise. The digital sound processor analyses all the frequency bands and increases the volume according to the vehicle’s speed – via individual adjustment of each loudspeaker and the different frequency ranges.

Technical data, equipment and appointments may vary from country to country.
