The car will be using the Bluetec diesel system with a technology for hybrid systems that they developed with BMW. The one on display in Geneva has a diesel four 2.2L with twin turbochargers. This powerplant can output an excellent 204 horsepower.

The same engine is featured at the 2011 E250 Bluetec that took spotlight at the 2009 New York Auto Show. The fuel mileage of the powerplant is estimated to be 39 mpg while cruising on the highway and 29 mpg while on the city streets.

The electric motor and lithium ion battery installed on the E300 hybrid are similar to the configuration used by the 2010 S400 Hybrid that kicked off sales last year.

The drivetrain of the E300 will only be a mild hybrid. This means that the car’s electric motor will only boost the power of the combustion engine and will be utilized to restart the car from full stops. The E300 will not be capable of running pure electric like the Toyota Prius – but it’s a hybrid car none the less.

The mild hybrid setup will not really be an issue. Initial tests show that the fuel economy is pegged at 57 mpg based on the combined cycle in Europe. This translates to a CO2 emission of about 109 grams per kilometer.

There is no need to worry though if you are hoping for more green cars in the market. There are several European car producers that are on the race to come up with the technology as early as 2011. French carmaker Citroen promised to use a diesel-hybrid engine with their new baby the DS5 but this will have to wait until 2011.

Mercedes-Benz was able to step on the pedal and may hit their goal. Mercedes Benz will be able to deliver a hybrid diesel-electric vehicle and also launch a version of the technology through the E-Class before the end of the year. Deliveries of the hybrid units will start by the first months of 2011.

The E-Class hybrid will be labeled E300 Hybrid and will be depending on a 2.2L 4-cylinder turbo diesel engine paired to a lithium ion electric motor. This engine is also used by the E250 Bluetec running on diesel.

The E300 hybrid will only be on a mild hybrid configuration. This means that the car cannot really run on a full electric mode but the electric motor is just used to boost the power of the combustion engine and restarting the vehicle from a stop. The fuel consumption though is still very good and will be more than 50mpg.

The components of the Mercedes-Benz hybrid will be similar in configuration with the S400 Hybrid. The S400 is doing well in the local German market with makes up 15% of the sales figures of the S-Class. The modular platform being followed by the carmaker allows the sharing of the components of their different units. Diesel hybrid configuration is also being planned for the GL, ML, and GLK SUV.

Mercedes-Benz’ F800 Style represents what future Mercedes-Benz will look like. The four-door, five-seat coupe blends safety, future driving technology, and comfort with the new design language of the company.

The interior of the concept vehicle is quite roomy and makes use of display concepts and intelligent controls for seating. The concept vehicle has two versions. One version will be purely utilizing an electric drive which runs on fuel cells and has a decent range of 375 miles. Another version is a hybrid plug-in that can run on pure electricity for 18 miles.

F800 Style plug-in hybrid car will depend on the 300 horsepower V-6 gasoline powerplant and an electric motor that uses lithium ion battery packs. According to insiders, the F800 plug-in variant will be able to zoom from 0 to 60 mph in just 4.7 seconds. It will hit 155 mph as its top speed. The fuel efficiency of this concept will be pegged at 81 mpg. The electric vehicle mode of this variant will allow it to hit 75 mph for its top speed. The new generation of Mercedes-Benz S Class will feature an engine like this one.

The pure electric variant of the F800 Style will depend on an electric motor that has an output of 136 horsepower. The engine will also make use of a hydrogen fuel cell just like the one that will be installed on the F-Cell of the B-Class due to roll out in the near future.
