German car magazine Auto Bild is reporting in its latest issue that Mercedes-Benz is working on a superlight E-Class.

The lightweight edition of the E-Class will be made of carbon fiber (with more rigidity than steel) and weigh in at around 1,300 kg (2860 lbs) - which will be 350 kg (770 lbs) less than the standard model.

The superlight E-Class will also see a new design, influenced by the CLS, with engineers free to go with features such as gullwing doors or no B-pillar given the rigidity of the carbon structure.

The model also seems intended to lower Mercedes-Benz's fleet fuel-economy and CO2 quotients because the automaker is considering both hydrogen fuel-cell and petrol-hybrid drivetrains for the lightweight E-Class.

The superlight E-Class is due in 2015.
