Lifecycle CO2 emissions of new Mercedes CLS 30% lower than predecessor

Over its entire life cycle—from production and operation over more than 250,000 kilometers up to recovery— the new Mercedes-Benz CLS emits 30% less CO2 than its predecessor did when it was launched in 2004, according to TÜV Süd.

Nitrogen oxide emissions have been reduced by 21% overall. Over the entire life cycle, the primary energy savings amount to 27% compared to the predecessor; this corresponds to the energy content of 9,300 liters of gasoline.

The reduction is largely due to the significant reductions in consumption. In the CLS 350 BlueEFFICIENCY gasoline model, for example, consumption has dropped from the predecessor’s figure of 10.1 L/100 km (23.3 mpg US) on its market entry in 2004 to 6.8 L/100 km (34.6 mpg US), representing a reduction in fuel consumption of up to 33%.

The CLS already meets the mandatory recycling rate of 95% by weight that will come into force on 1 January 2015; the future requirements in vehicle recycling were already taken into account at the development stage. Closing material loops plays an important role here. The new CLS makes use of a total of 61 components with a combined weight of 49 kg that can be partly produced from high-quality recycled plastics. The mass of approved recycled components has been increased by 96% over the previous model.

56 components for the CLS with a total weight of almost 31 kilograms are made from natural materials. The trunk floor consists of a cardboard honeycomb structure, for example, and for the tank vent filter the Mercedes engineers made use of coke.
