23rd February, 2011

With the new engines for the S-Class, Mercedes-Benz once again raises the standard for efficiency and exclusivity in the luxury saloon segment. The Mercedes-Benz S-Class comes with highly efficient engines with direct petrol injection whose output has been increased by as much as 12.5 per cent and petrol consumption has been reduced by as much as 24 per cent.

The new S 350 BlueEFFICIENCY with a petrol V6 engine, for example, is content with just 9.0 litres of premium petrol per 100 kilometres (combined cycle). That corresponds to CO2 emissions of 210 g/km (previous model 9.8 l/100 km, 234 g/km CO2).

In the new S 500 BlueEFFICIENCY, the combined fuel consumption is 10.5 litres per 100 kilometres; that is equivalent to 244 g/km CO2. Crucial to this enhanced efficiency is the newly developed BlueDIRECT technology with third-generation spray-guided direct petrol injection in combination with the 7G-TRONIC seven speed automatic transmission.

Innovations like the Active Blind Spot Assist and Active Lane Keeping Assist ensure that the S-Class remain the yardstick for automotive progress also in the area of active safety.

S 350 BlueEFFICIENCY: the most economical petrol model in the luxury class

Compared with the previous power plant with the same displacement, the output of the new V6 petrol engine of the S 350 BlueEFFICIENCY has increased by 12.5 per cent from 200 kW to 225 kW. The torque has increased by 5.7 per cent from 350 to 370 Newton metres. Parallel to the increase in output, consumption has been reduced by 8.2 per cent from 9.8 litres of premium petrol per 100 kilometres to 9.0 litres per 100 kilometres The CO2 emissions likewise have declined by 10.3 per cent from 234 grammes per kilometre to 210 grammes per kilometre.

New V8 biturbo engine for S-Class with great potential for savings

The new V8 biturbo engine in the S 500 BlueEFFICIENCY and as recently seen in the new CL 500 BlueEFFICIENCY, with its 4,663 cubic centimetres displacement, produces 320 kW despite 0.8 litres less displacement. It is still around 12 per cent more powerful than its predecessor, which had an output of 285 kW.

The fuel consumption of the S 500 BlueEFFICIENCY is 10.5 litres 100 kilometres, 3.7 per cent (short wheelbase) and 1.8 per cent (long wheelbase) better than that of the previous model. An outstanding value in this output category, it equates to CO2 emissions of 244/249 grammes per kilometre.

S 350 BlueTEC: most fuel-efficient S-Class in Australia

The series of highly efficient Mercedes-Benz internal combustion engines is made complete by the new 3.0-litre diesel of the S 350 BlueTEC. The combined fuel consumption is only 7.0 litres of diesel fuel per 100 kilometres – eleven per cent less than in the previous model. That equates to CO2 emissions of 185 grammes per kilometre. The S 350 BlueTEC is thus the most fuel-efficient S-Class in Australia. Thanks to AdBlue® emission control as standard, the 190 kW S 350BlueTEC additionally ranks among the world's cleanest diesel models.

The 380 kW 12-cylinder biturbo engine in the S 600 remains the most powerful engine for the S-Class and now also complies with the Euro 5 emissions control standard.

S 63 AMG

The top-of-the-range S-Class V8 model, the Mercedes-Benz S 63 AMG, is to benefit from a completely newly developed powertrain. The AMG 5.5-litre V8 biturbo engine with a peak output of up to 400 kW and torque of up to 800 Nm, in combination with the unique AMG SPEEDSHIFT MCT 7-speed sports transmission, contributes towards a considerable reduction in consumption and emissions, while at the same time increasing maximum power and torque. With a fuel consumption of 10.6 litres per 100 kilometres, the new high-performance Saloon not only undercuts its direct competitors – it is also more than 25 per cent more economical in terms of its fuel consumption than the previous model with naturally aspirated V8 engine.

The new S 63 AMG marks the start of a new chapter in the "AMG Performance 2015" drive strategy: Mercedes-AMG is continuing this impressive story and is meeting its promise to continuously reduce both the fuel consumption and emissions of new models with the new engine/transmission combination – while reaching new heights with the central AMG brand value of "performance".

According to Ola Källenius, head of Mercedes-AMG GmbH: "We are heading into a new era with the S 63 AMG: for the first time we have combined spray-guided direct petrol injection with biturbocharging and the start/stop system. Together with the AMG SPEEDSHIFT MCT 7-speed sports transmission, we have reduced both fuel consumption and emissions significantly – while at the same time increasing output and torque."

The new AMG 5.5-litre V8 biturbo engine will play a significant role in the Mercedes-AMG model strategy over the coming year. The unique AMG SPEEDSHIFT MCT 7-speed sports transmission will also help to ensure that future high-performance AMG vehicles benefit from an exciting and at the same time economical transmission of power. The new engine/transmission combination marks a further milestone in the history of Mercedes-AMG, which began in 1967.

Direct petrol injection with spray-guided combustion and twin turbocharging

Designated internally as the M157, the new V8 engine is a prime example of efficiency and features a whole host of impressive technological highlights: for the first time AMG is taking advantage of direct petrol injection with sprayguided combustion and piezo injectors. This technology enables improved fuel economy thanks to higher thermodynamic efficiency, which in turn leads to lower exhaust emissions. AMG has combined the spray-guided combustion with biturbo charging. Other highlights of the innovative, original eight-cylinder engine from Affalterbach include full aluminium crankcase, four-valve technology with variable intake valve timing, air/water charge air cooling, generator management and also standard Controlled Efficiency start/stop function. Compared with the AMG 6.3-litre naturally aspirated V8 engine with a displacement of 6,208 cc, the new AMG 5.5-litre V8 biturbo engine achieves all this with a displacement of 5,461 cc. This high-tech package leads to a high output and torque yield, together with fuel consumption figures that are unrivalled in the competitive line-up. The AMG 5.5 litre V8 biturbo engine develops a peak output of 400 kW and maximum torque of 800 Nm. A look at the performance diagrams shows that no other engine in this output class achieves the figures delivered by the new AMG biturbo. The major difference between the two performance classes is an increase in the maximum charge pressure from 1.0 to 1.3 bar.

Quantum leap: fuel consumption reduced by more than 25 per cent

With a fuel consumption figure of only 10.6 litres per 100 kilometres, the new S 63 AMG is 3.9 litres more economical than the previous model powered by the naturally aspirated AMG 6.3-litre V8 – despite an increase in output of 14 kW and in torque of 170 Nm. Engine specialists consider this achieved fuel saving of more than 25 per cent to be nothing less than a quantum leap. CO2 emissions have likewise been significantly reduced: at 247 grammes per kilometre, the figure is almost 30 per cent lower than for the previous model.

With figures like these, the new S 63 AMG is not only considerably better than all its competitors, but also more fuel-efficient than much less powerful cars in this segment.

Sports car-level performance

At the same time the S 63 AMG delivers superior performance at sports car level: the high-performance saloon accelerates from zero to 100 km/h in 4.5 seconds, and has an electronically limited top speed of 250 km/h.

It is not only the unrivalled torque delivery of this turbocharged eight-cylinder that makes the heart beat faster, as the agile responsiveness with no irritating charger delay leads to an effortlessness and dynamism previously unknown in this output class. This AMG high-performance engine naturally meets all the requirements with respect to smooth, quiet running and the comfort on long journeys that is to be expected of a Mercedes-Benz.

AMG SPEEDSHIFT MCT 7-speed sports transmission

Power is transferred by the AMG SPEEDSHIFT MCT 7-speed sports transmission used exclusively by AMG, which is already familiar from the SL 63 AMG and E 63 AMG and combines high emotional appeal with outstanding driving dynamics, impressive comfort and a high level of efficiency. The wet start-up clutch replaces a conventional torque converter, and helps to save fuel. The exemplary fuel economy is also in large measure due to the standard start/stop function. This system is active in the transmission's Controlled Efficiency ("C") mode, and switches the eight-cylinder engine off when the car comes to a stop. In"C" mode the sports saloon always starts off in second gear, and the transmission shifts to the next, higher gears at a decidedly early stage. With its high torque at low engine speeds, the V8 engine encourages a smooth, effortless driving style.

The eight-cylinder biturbo engine also features the generator management system familiar from the E 63 AMG: whenever the engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way. In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage. This reduces the load on the engine and makes for fuel savings of around 0.15 litres per 100 kilometres (combined), and up to 0.2 l/100 km in city traffic with its frequent overrun and braking phases.

Engine production – tradition of hand-built excellence

Like all other AMG engines, the new eight-cylinder biturbo is assembled by hand in the AMG engine shop taken into commission in 2002. Highly-qualified technicians assemble the M157 according to the "one man, one engine" philosophy, maintaining the very strictest quality standards. This painstaking care is attested to by the signature on the characteristic AMG engine plate.

Long tradition of powerful AMG V8 engines

Powerful eight-cylinder engines are an inseparable part of AMG's corporate history. Established in 1967, the company immediately caused a stir with the 300 SEL 6.8 AMG which succeeded in taking second place at the 24-hour races at Spa- Francorchamps (Belgium). The AMG racing saloon was technically based on the Mercedes-Benz 300 SEL 6.3. With an engine output of 184 kW (250 hp) at 4,000 rpm and a top speed of 220 km/h, this luxury V8 saloon was Germany's fastest regular production car at the time. Classic tuning as well as an enlarged displacement from 6,330 to 6,835 cc resulted in an increase in output to 315 kW at 5,500 rpm and in torque from 500 to 608 Nm.

A further milestone in the AMG engine story was the M117, the first eight cylinder unit with four-valve technology. With a displacement of 5.6 litres, 265 kW and 510 Nm of torque, this V8 accelerated the Mercedes-Benz 300 CE 5.6 AMG to a top speed of 303 km/h in 1987. This made the coupé the fastest German car in series production, and American fans nick-named it "The Hammer". Another important engine in the history of AMG was the supercharged AMG 5.5 litre V8 introduced in 2001: the M113 K developed an output of up to 428 kW and torque of 800 Nm. The supercharged AMG 5.5 litre V8 in the SLR McLaren of 2003 was even more powerful – the M155 developed up to 478 kW and 820 Nm.

The year 2005 saw the debut of the AMG 6.3 litre V8 engine; depending on the model, the naturally aspirated, high-revving M156 developed up to 386 kW and 630 Nm. Exclusively reserved for the new SLS AMG, the likewise 6.3 litre M159 has a maximum output of 420 kW and maximum torque of 650 Nm.

Numerous victories in the "International Engine of the Year Awards"

The supercharged AMG 5.5 litre V8, the AMG 6.3 litre V8 and the AMG 6.0 litre V12 biturbo were all able to win the Best Performance Engine category in the International Engine of the Year Awards. The AMG 6.3 litre V8 also won in 2009 and 2010 in the "Above 4 litres" class.

New optional AMG triple-spoke light-alloy wheels

In visual terms, the new S 63 AMG is distinguished by a number of subtle touches: "V8 Biturbo" lettering on the mudguards points to the new powertrain. Also new are the optional AMG triple-spoke light-alloy wheels, painted in titanium grey and with a high-sheen finish, and fitted with 255/40 or 275/40 R 19 tyres. In the interior, the S 63 AMG boasts a newly designed AMG instrument cluster with "AMG V8 Biturbo" starting screen. The standard PASSION leather upholstery has been enhanced with new, contrasting colour stitching.

A new range of attractive optional appointments is now also available for the S 63 AMG: the Bang & Olufsen BeoSound AMG high-end sound system, developed especially for the S-Class, ensures an exceptional listening experience. With a total output of 1,200 watts, 15 loudspeakers, acoustic lens tweeters in the A and B-pillars as well as a digital sound processor (DSP), it transforms the Saloon into a full-blown concert hall with perfect acoustics.

Active Lane Keeping Assist and Active Blind Spot Assist

The unique combination of innovative camera and radar-based driver assistance systems has been enhanced even further with immediate effect with a view to perfecting the vehicle's active and passive safety. The new Active Lane Keeping Assist comes into play when the S 63 AMG unintentionally strays over a solid line on the right or left of a lane or on the outside of a bend. In such cases the Electronic Stability Programme ESP® applies the brakes to the wheels on the opposite side of the vehicle to prevent it from unintentionally straying from its lane.

Also new is the Active Blind Spot Assist, which warns the driver by displaying a red warning in the glass of the relevant exterior mirror when it detects that changing lanes would be too dangerous. If the driver ignores the warning signal and a vehicle in an adjacent lane comes too close, the ESP® takes corrective action by applying the brakes to the wheels on the opposite side of the vehicle.

Crosswind stabilisation, Torque Vectoring Brake and Direct-Steer system

The AMG sports suspension based on Active Body Control (ABC) provides crosswind stabilisation as standard equipment: thanks to this function, influences caused by crosswinds are compensated for, or – in the case of strong gusts – reduced to a minimum. ABC compensates against the effect of crosswinds by adjusting the wheel load distribution within milliseconds, using the yaw-rate and lateral acceleration sensors of the ESP®.

Also making up the standard equipment is the Torque Vectoring Brake: when cornering, brief direct application of the brakes has an effect on the vehicle's inner rear wheel so that the saloon corners precisely and under control at all times. The Torque Vectoring Brake is an additional feature of the Electronic Stability Programme and not only noticeably improves responsiveness but also active handling safety in critical conditions. The driving experience is further heightened thanks to the Direct-Steer system: with its variable ratio depending on steering angle, it helps to ensure a more direct response when cornering, and therefore more responsive handling – in brief: enhanced driving pleasure at the wheel of the Mercedes-AMG S-Class.

AMG high-performance braking system with double floating brake calliper

Based on the ADAPTIVE BRAKE system, the AMG high-performance braking system continues to provide optimum fade resistance, deceleration and sensitivity. The front axle features a double floating brake calliper. This exclusive technology combines the advantages of a sliding-calliper disc brake – reduced heat transfer to the brake fluid and clear advantages in terms of comfort thanks to the brake lining guide mechanism – with the efficiency of an extra large fixed calliper brake.

Top-of-the-range S-Class models from Mercedes-AMG appeal to customers worldwide

Exclusivity and dynamism, effortless superiority and high tech: both the S 63 AMG and the top-of-the-line V12 model, the S 65 AMG, embody all of these characteristics. Since their market launch some four years ago, the S-Class models from AMG have won the hearts of more than 10,000 customers around the world – turning them into the clear market leaders in the small yet highly exclusive high performance luxury saloon segment. The twelve-cylinder S 65 AMG model now produces 463 kW and will also be celebrating its market launch in 2011.
