** The Porsche Boxster S is homologated to the EU5 standard. To provide a better comparison of fuel consumption with the former model and other cars still homologated to EU4, the EU4 consumption figures are also shown above. When homologating a car to EU5, the manufacturer must provide for a new fuel grade with a higher share of ethanol. Displacing the same volume, such fuel has a lower calorific value than the fuel required for homologation to EU4. Hence, fuel consumption under the EU5 standard is slightly higher than with EU4 on the same CO2 emissions.
