Even more economic and eco-friendly: Mercedes-Benz Integro touring coach with a new generation of Euro VI engines

Don't Copy From This Blog...

The new generation of BlueEfficiency Power engines and the transition to the Euro VI emissions standard are the focus of the Mercedes‑Benz Integro in 2013. Considerably lower fuel consumption and further reduced exhaust emissions are the result.

BlueEfficiency Power: two engines, four output variants

The Euro-VI-compliant Blue Efficiency Power engines of the Integro are vertically installed in-line six-cylinder engines. The new, particularly compact Mercedes‑Benz OM 936 series with 7.7 l displacement is used in the two-axle vehicles. The output amounts to 220 kW (299 hp) or 260 kW (354 hp), both at 2200 rpm. Torque is 1200 or 1400 Nm respectively.

The equally new Mercedes‑Benz OM 470 with 10.7 l displacement is used in the three-axle vehicles. Its output is either 265 kW (360 hp) or 290 kW (394 hp) at 1800 rpm. Maximum torque is 1700 Nm or 1900 Nm.

Both engines boast common-rail injection. The injection pressure is generated via a high-pressure pump for the OM 936 or by the X-PULSE injection system for the OM 470 with a pressure booster in the injector.

Strong response, low weight, reduced fuel consumption

The new engines are characterised by high torque at extremely low engine speeds, a spontaneous response and a very smooth running performance. They also excel with a very favourable weight. Despite the additional assemblies required in order to comply with Euro VI, weight has been optimised and reduced with numerous individual measures and is even lower than that of the Euro V predecessor model.

The efficiency of the engines is outstanding: depending on the usage profile and the drive train combination, the fuel consumption of two-axle vehicles is 2-5 % lower than that of predecessors whilst it is up to 2 % lower for three-axle vehicles. The consumption of AdBlue and engine oil is also considerably lower. Not only the new engines, but also the optimised auxiliary equipment such as the regulated generators and the efficient air compressor have contributed to the low fuel consumption of the Integro.

Complex emission control system compliant with Euro VI

The strict regulations for the coming Euro VI emissions standard require a complex emission control system. For this reason Mercedes‑Benz has combined the well-established BlueTec engine technology with SCR technology and AdBlue injection with exhaust gas recirculation as well as a particle filter.

Fast, comfortable, easy-to-operate: the GO 250-8 PowerShift transmission

Mercedes‑Benz also offers the Integro with the eight-speed GO 250-8 PowerShift bus transmission as an alternative to the six-speed manual transmission and the ZF EcoLife automatic transmission with torque converter. Drivers profit from the progressive synchronisation of the transmission as well as from gearshifts which are as fast as they are comfortable. The operation of the transmission via the joystick gear lever is extremely simple. Almost wear and maintenance-free, the clutch is also new to this transmission. A centrically located, pneumatically operated clutch cylinder renders mechanical parts such as the clutch release fork, clutch release bearing and the servo assistance unnecessary.

A powerful yet lightweight retarder

The driver operates the new integrated retarder as usual via the steering column switch. It achieves a braking torque of up to 3500 Nm. The retarder is designed as a secondary retarder and uses the engine coolant as its brake fluid and coolant. This eliminates the previous oil/water heat exchanger and the associated oil changes for the retarder.

Striking design of rear-end for the Euro VI variants

The dynamic design of the rear-end of the Euro VI variant with its newly designed engine compartment flap is striking and distinctive. It is closely related to the Travego Edition 1, the touring coach flagship of Mercedes‑Benz. The symmetric form conceals the completely new design of the cooling and ventilation system for the engine. The position of the radiator behind a bulkhead on the right-hand side together with the ventilation is also an important element.

The specialist for inter-city journeys and excursions

The Integro's proven agenda remains unchanged: consistently tailored to inter-city travel, this two-door specialist with three variants on two axles (Integro, Integro M) or three axles (Integro L), measuring between 12.14 m and 14.92 m in length covers everything from short regular-service routes in suburban traffic to long-distance inter-city travel. Its comfortable design makes it perfect both for shuttle services and excursions. Thanks to this successful combination of comfort and efficiency and its flexibility with regard to use, the Integro is a double-earner and therefore particularly economic.

At a press conference hosted by Bridgestone Corporation and the New York International Auto Show, the Mercedes-Benz S 250 CDI BlueEFFICIENCY was declared the 2012 World Green Car.

The Mercedes-Benz S 250 CDI BlueEFFICIENCY was chosen from an initial entry list of 23 new vehicles from all over the world, then three finalists: the Mercedes-Benz S 250 CDI BlueEFFICIENCY, the Ford Focus Electric, and the Peugeot 3008 Hybrid.

This is the second time in World Green Car history that a Mercedes-Benz technology has won this prestigious honour. The Mercedes-Benz E 320 BlueTEC technology was the 2007 World Green Car winner.

The all new Mercedes-Benz SL 350 BlueEFFICIENCY: Light, athletic, luxurious

Don't Copy From This Blog...

With the all-new SL, Mercedes-Benz is continuing a tradition that began 60 years ago, since when "SL" has always stood for a symbiosis of sportiness, style and comfort – and for trailblazing innovations. The SL's bodyshell consists almost entirely of aluminium for the first time, and weighs in at up to 140 kilograms less than its predecessor. The highly rigid all-aluminium bodyshell provides the basis for emphatically sportier, agile handling accompanied by exemplary ride and driving comfort. Enhanced driving dynamics are ensured by new BlueDIRECT engines.

The new V6 power unit of the new SL 350 BlueEFFICIENCY generates 225 kW (306 hp) from an unchanged displacement of 3499 cubic centimetres, and delivers 370 newton metres of torque. It consumes a modest 6.8 litres of fuel per 100 kilometres, and is therefore almost 30 percent more economical than its predecessor. The SL 350 BlueEFFICIENCY is equipped with an ECO start/stop function as standard.

The 7G-TRONIC PLUS automatic transmission, which has been optimised for fuel consumption and comfort, also contributes to fuel efficiency. The modesty of the BlueDIRECT engines in no way compromises the dynamism of the Roadster. On the contrary, the SL 350 sprints from zero to 100 km/h in 5.9 seconds and is therefore three tenths of a second faster than its predecessor.

Aerodynamics: new standards

The design of the new SL not only meets high aesthetic demands – it also boasts exemplary aerodynamic qualities. As such, the roadster merits best marks in its segment in four important disciplines:
- it has the lowest drag coefficient (Cd = 0.27 for the SL 350);

- it has the lowest wind noise, virtually on a par with a closed saloon;

- it provides the best comfort for open-top motoring, and can be driven with the roof down even at high speeds;

- there is virtually no soiling of the side windows.
