Mercedes-Benz S-Class

Four years after the market launch of the W 221 model series, Mercedes-Benz is presenting the 2009 S-Class. Trailblazing innovations in the areas of comfort and drive engineering combined with state-of-the-art technology for enhanced safety consolidate the Mercedes-Benz flagship's position as the brand's innovation driver and underscore its pioneering role in the automotive industry as a whole. The technology highlights include the world's first standard production hybrid drive with a lithium-ion battery in the S400 HYBRID, which makes the top-of-the-line Mercedes-Benz model the most economical petrol-engine luxury saloon. The fuel consumption of 7.9 litres per 100 kilometres corresponds to carbon dioxide emissions of just 186 grams per kilometre.

The engine range further includes eight modern petrol and diesel engines that require up to seven per cent less fuel. With an average fuel consumption of 7.6 litres of diesel, the S 350 BlueEFFICIENCY is one of the most efficient models in the luxury segment. The S-Class's traditionally exemplary standard of safety is further enhanced by a unique combination of innovative camera- and radar-based driver assistance systems which turn the luxury saloon into an "intelligent" partner on the road. These systems include Adaptive Highbeam Assist, Lane Keeping Assist, Speed Limit Assist and the advanced Night View Assist PLUS facility. Other innovations are the ATTENTION ASSIST drowsiness detection function and automatic crosswind stabilization.

With 270,000 units sold since its market launch in autumn 2005, the W 221-series S-Class is the world's most successful luxury saloon, and seamlessly continues the success story of the flagship model in the Mercedes line-up. Since 1951, when the model 220 began the lineage of the S-Class, Mercedes-Benz has delivered around 3.3 million passenger cars from this model series to customers.

The 2009 S-Class once again represents the cutting edge of automotive development. Mercedes-Benz's technology leadership is demonstrated by the new S 400 HYBRID, which is the first production vehicle in the world to feature a hybrid drive with a lithium-ion battery. "The S 400 HYBRID is an important milestone on the way to emission-free mobility," notes Dr Dieter Zetsche, CEO of Daimler AG and head of Mercedes-Benz Cars. "Our first series production hybrid car exemplifies Mercedes-Benz's long-standing development strategy geared towards sustainability, with its clearly defined aim of producing economical and environment-friendly premium cars without compromising on safety, comfort and superior performance."

The first hybrid drive in a series production car from Mercedes-Benz makes this S-Class model the most economical petrol-engined luxury saloon. The fuel consumption of 7.9 litres per 100 kilometres corresponds to carbon dioxide emissions of just 186 grams per kilometre. This is the lowest level worldwide in this vehicle segment, confirming the new S400 HYBRID as the "CO2 champion of the luxury class".

The new S400 HYBRID is the first car to be designed on the basis of the highly intelligent modular concept developed by Mercedes-Benz to give its customers the best hybrid solution for their requirements.

The compact hybrid module combines the hybrid functions of an automatic start-stop system and energy recuperation. In all, this means that the S400 HYBRID sets a new standard in its class, making it the world's most economical luxury saloon with a petrol engine.

The excellent fuel consumption and the low CO2 emissions of the S400 HYBRID are accompanied by truly superior performance potential: the modified 3.5 litre petrol engine generates 205 kW/275 hp, while the electric motor produces 15 kW/20 hp and starting torque of 160 Nm.

The Mercedes-Benz S400 HYBRID is based on the S 350, and features an extensively modified drive train. This encompasses a further development of the 3.5-litre V6 petrol engine, an additional magneto-electric motor, the 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary power and control electronics, the voltage converter and the high-voltage lithium-ion battery.

Apart from the trailblazing hybrid of the S400 HYBRID, the range of engines for the 2009 S-Class comprizes eight other powerful units: two diesel variants and six petrol engines with six, eight and twelve cylinders. Detailed fine-tuning of these engines has been supplemented with addition fuel economy measures as part of the BlueEFFICIENCY package. These include aerodynamic optimization, demand-controlled fuel pumps and the fuel-efficient gearshift programme for the standard 7G-TRONIC automatic transmission. These measures have enabled Mercedes-Benz developers to reduce fuel consumption and CO2 emissions by up to seven percent compared to the preceding models. By means of additional well-aimed aerodynamic measures, the Mercedes-Benz engineers have also managed to reduce wind noise, thus further enhancing the standard of ride comfort.

With diesel fuel consumption of 7.6 litres per 100 kilometres and CO2 emissions of 199-201 grams per kilometre, the S 350 CDI BlueEFFICIENCY (173 kW/ 232 hp) likewise boasts outstanding figures for the luxury class. Mercedes-Benz achieves this exemplary efficiency with a tailor-made BlueEFFICIENCY package, which also includes closed underbody panelling and decoupling of the 7G‑TRONIC automatic transmission at standstill.

The 3.0 litre diesel engine is also used in the S 350 CDI 4MATIC. The second diesel variant is the eight-cylinder S450 CDI(235 kW/315 hp) with a displacement of 4.0 litres. The range of petrol engines comprizes the six-cylinder S 350/ S 350 4MATIC (200 kW/268 hp) with a displacement of 3.5 litres and the two eight-cylinder units in the S450/S450 4MATIC (250 kW/335 hp; displacement 4.7 litres) and S 500/S 500 4MATIC (285 kW/382 hp; displacement 5.5 litres). The flagship model is still the S600 with the 380 kW/510 hp twelve-cylinder biturbo unit (displacement 5.5 litres), which accelerates the luxury saloon to 100 km/h in 4.6 seconds. The Mercedes-AMG high-performance contributions to the range are the S63 AMG with its 386 kW/518 hp V8 engine (displacement 6.2 litres) and the S65 AMGwith a 450 kW/603hp twelve-cylinder engine (displacement 6.0 litres).

In line with its self-assured character and its claim to be a technological trendsetter, the 2009 S-Class also sets standards where onboard infotainment is concerned. As a world first, on request Mercedes-Benz will equip its flagship model with the new SPLITVIEW technology for the COMAND control and display system centrally located in the centre console. This innovative display concept allows the driver and front passenger to view different content simultaneously on one and the same screen. While the driver uses the map-based navigation system, for example, the front passenger can be watching the latest film on DVD.

Mercedes-Benz has also extended the standard control and display system COMAND with additional functions, for example an SD memory card slot. Other new features include a modified Bluetooth® interface, which provides for a wireless link between a mobile phone and the standard onboard hands-free system, and a USB interface. These enable customers to export saved data and import them into any other S-Class. It is also possible to transfer navigation data. As an optional extra Mercedes-Benz also offers a Media Interface – a universal interface in the glove compartment for mobile audio devices such as an iPod® and USB stick (standard for S400 HYBRID and S600).

The optionally available COMAND APS (standard for S400 HYBRID and S600) is additionally equipped with a Europe-wide navigation system whose data are stored on a 40 GB hard disc. This allows particularly fast route calculation. The high level of navigating convenience is also aided by the detailed three-dimensional city map mode.

Musical entertainment is provided by a radio, a CD/DVD player with MP3 function, an equalizer with speed-dependent volume control and the Music Register with a 7.2 GB hard disc which stores around 2500 digital music files in MP3, AAC or WMA format. The system recognizes music files played on CD, DVD or from the Music Register using its stored Gracenote® database, and shows the title, album and performer in the colour display. The new Music Search function enables S-Class drivers and passengers to search SD memory cards, USB sticks, CDs and DVDs for specific music titles and performers. COMAND APS also includes the latest-generation LINGUATRONIC voice-operated control system, which operates the navigation, telephone and audio devices by whole-word commands. This has the advantage that the driver no longer has to spell out his commands.

Mercedes-Benz has also increased the range of rear-seat entertainment functions in the 2009 S-Class. Passengers in the rear now have a remote control unit which enables all the audio and telematics functions of COMAND to be operated, plus access to external devices via the Media Interface. Mercedes-Benz also offers a rear-seat entertainment package with two eight-inch displays on the rear surfaces of the front seat head restraints, two wireless headphones and a separate CD/DVD player with connections for external audio and video devices.

The "Logic7" surround sound system developed by Mercedes-Benz together with the audio specialists harman/kardon® delivers outstanding performance with three-dimensional sound as a natural 360-degree musical experience for all passengers.

The modified design reflects the effortless superiority and power of the S-Class Saloon. It is characterized by the more pronounced arrow-shape of the radiator grille, plus a new front bumper with a discreet light-catching contour and a chrome strip below the cooling air intakes. In future the exhaust tailpipes of all S‑Class variants will be visibly integrated into the rear bumper. The headlamps have bi-xenon technology as standard.

An even more dynamic look is ensured by the LED Light package with its striking LED arrays for daytime driving lights, indicators and marker lights (standard for S400 HYBRID and S600). These lend an unmistakable day-and-night design to the front end. The rear end is characterized by tail lights in an innovative LED design. Here too, a total of 52 LEDs in the form of a double-C form an unmistakable light signature.
