Mercedes-Benz, the inventor of the automobile, celebrates its 125 birthday this year. Under the motto “Mercedes-Next,” the automaker presented six world premieres at the Frankfurt Internationale Automobile Ausstellung (International Automobile Show). The new cars include the recently announced SLK 250 CDI , the completely new B-Class, and two concept cars,  the B-Class E-Cell and the F125!) .

With the presentation of the F125! (the name is based on the company’s 125th anniversary) Mercedes-Benz provides a view of a potential S-Class of the future. The F-Cell hydrogen research vehicle is equipped with four electric motors close to the wheels and can go up to 1.000 kilometers (621 miles) without refueling. Its F-Cell plug-in hybrid system uses the automaker’s latest high performance lithium-sulfur high voltage battery. The battery powers the car for the first few miles before the F-Cell is activated. It transfers hydrogen and air in a chemical reaction to energy which powers the batteries of the F125!. This leads to a combined system power of 313 hp.

Another star of the Mercedes-Benz show is the concept car of the B-Class E-Cell Plus with an estimated range of 600 km (373 miles). An additional gasoline engine works as a range extender for the electric lithium-ion battery, which is stored in the Energy Space. The Energy Space is a specially developed, space-saving intermediate floor in the front of the rear axle.

Mercedes also unveiled the completely reworked B-Class. In its second generation, the new B-Class offers buyers a numerous innovations which are new to the compact segment. Attention Assist, which has been available for several years on larger Mercedes vehicles including the E350 BlueTec sedan that recently joined our new long-term test fleet,  and the Collision Prevention Assist are among the most important ones. Also the engines of the new B-Class have been reworked with new direct fuel injection technology. The new diesel-powered B-Class is rated with an average fuel consumption of only 4.4 l/100 km (53 mpg).

The current fleet of the SLK- and M-Class cars will get new diesel engines. The Mercedes-Benz SLK 250 CDI is the first diesel-powered roadster. It features a four-cylinder diesel engine with a power output of 150 kW / 204 hp. The new ML 250 BlueTec 4MATIC has a fuel consumption of only 6.0 l/100 km (39 mpg) a 25% improvement over its predecessor.
