Mercedes-Benz S-Class chief engineer Hermann-Joseph Storp has shed some light about the company's next-gen flagship model.

Mercedes-Benz still hasn't finished coming out with derivatives of the W222 S-Class but they have already started thinking about the next generation scheduled to come out before the end of the decade. During a press gathering this month at Geneva Motor Show, company chief engineer Hermann-Joseph Storp said Mercedes-Benz will focus on making the S-Class even greener and one way would be to use more aluminum and carbon fiber reinforced plastics (CFRP) in the car's construction.

While the W221 S-Class used just over 10 percent of aluminum in its body, the new one is almost half made from aluminum. CFRP is used only in very high-end limited-run models but the material will find its way on more production models, one example would have to be the upcoming all-new BMW 5- and 7-Series.

The latest S-Class is up 20 percent more fuel efficient than its predecessor and the most frugal version is the S 300 BlueTEC Hybrid which returns 52.2 mpg US (67.2 mpg UK or 4.5 liters / 100 km) with CO2 emissions of 118 g/km, a remarkable figure taking into account the size and weight of the car. It will be interesting to find out by how much Mercedes-Benz will be able to improve these numbers for the next S-Class.
