Porsche is also looking at other ways to reduce fuel consumption including weight reductions like the magnesium doors on the new Panamera. They are also adding direct fuel injection to their engines which should provide a boost in both power and efficiency. In the past Porsche has been openly dismissive of diesel engines saying their weight and torque characteristics was incompatible with its cars. However, the success of newer high-performance diesels such as the Audis and Peugeots at Le Mans - as well as on the road - may be causing them to revisit that attitude too.
