Mercedes has introduced on the German saloon the concept of B-Class E-CELL PLUS, which promises an electric power range of 100 km.

Mercedes has announced for the new generation of B-Class a wide variety of ecological engines. The first step in this direction was made by the German engineers, the presentation of the B-Class E-CELL PLUS Concept, at home, on the Frankfurt Motor Show 2011. Being a plug-in hybrid, B-Class E-Cell Plus provides an electric motor with an output of 95 hp, used in tandem with a heat engine gasoline of 1.0-liter and 68 hp.

At low speeds, the latter one is feeding of Li-on machine with the help of a generator. When the speed increases, 1.0-liter gasoline engine comes discreetly on the front wheels through the new automatic transmission developed by Mercedes engineers.  The two engine units are mounted under the hood, along with the generator, while the fuel tank and the battery of Mercedes B-Class E-CELL PLUS is the car floor.

Performance of the concept can be considered on the top in the world of hybrid plug-in, so sprint 0-100 km / h in 11 seconds, top speed 150 km/h is valid, regardless of the selected drive. It’s scheduled to enter in mass production soon. Mercedes B-Class E-CELL PLUS will provide prospective customers to always check the remaining battery level and autonomy available via the Vehicle Homepage, available on the PC or smartphone.

Also, owners of B-Class E-CELL PLUS can use on-line application to schedule automatic car battery charge before you travel. Thus the battle and select the new plug-in hybrid club promises to be an interesting compact, B-Class face with rivals such as Toyota Prius Plug-in Hybrid or Opel Ampera.

Mercedes-Benz SLK 55 AMG will be presented in world premiere at the Frankfurt Motor Show 2011. But until then, here are the first details about this model.

Mercedes-Benz SLK 55 AMG expected to get the V8 with 5461 cc direct injection, code-named M152. An engine that displays very good value for a sports car: 422 CP/6.800 rpm respectively 540 Nm/4.500 rpm maximum torque.

In fact, we are talking about the same unit of the Mercedes-Benz CLS 63 AMG, but with many changes: lack of turbochargers, new intake system, a new fuel pump or longer valves. V8 engine proves very easy through the use of aluminum, with only 187 kg and piezoelectric injectors are capable of 200 bar pressure.

One of the strengths of the new V8′s SLK 55 AMG in the fight against CO2 emissions is the only operating system with 4 cylinders, system borrowed from Formula 1. Depending on conditions of use and speed of the car, the central control unit command decoupling for a half of the injectors, in “C” mode (Controlled Efficiency) of the automatic gearbox.

Basically, four-cylinder engine only works on a range of speeds between 800 and 3600 rpm, maximum torque available in this case its 230 Nm, enough to run at low speed in town or cruising on the highway. After 3600 rpm in just 30 milliseconds become operational the other cylinders (2, 3, 5 and 8), in a manner imperceptible to the driving.

The entire system is equipped with Start & Stop system plus one energy recovery from braking. Therefore, although the power it’s higher with 62 HP, consumption was reduced by 30% compared to previous generation of Mercedes-Benz SLK AMG: 8.5 liter / 100 km compared to 12 liters per 100 kilometers (CO2 emissions now amounts to 199 g / km and the engine is compatible with Euro 5).

Also at Frankfurt Motor Show 2011, the Germans will also present the most economical version of their Roadster: Mercedes-Benz SLK 250 CDI equipped with common-rail engine 2.1-liter with 204 hp and 500 Nm. The SLK will show 5.0 liters/100km average consumption and 130 g / km CO2 emissions.
