Like all automobile manufacturers, Porsche will soon have to deal with the new, and more severe, anti-pollution norms. Many solutions have been thrown up for the moment, not all of which are very orthodox, but one of which could be the adoption of the start&stop system on the noble six cylinder 911. This could see CO2 emissions decrese by about 10 g/km.

Apparently the brand’s customers are not all that enthusiastic about taking a drive with a Carrera that turns itself off at every red light. So how do you fix the problem?

By discovering new ways. The 911 is unlikely ever to be the champion of ecology (according to Thomas Wasserback it will be difficult to get it under 200 g/km), but with a series of different solutions the company should be able to shave off a few more grams without touching performance.

The delicate area in this operation is exactly that of the performance and apparently Porsche, to maintain performance and keep to emission levels, will reduce the power of the engines. Yes, you read that correctly.

In addition we will likely see a reduction in weight, achieved through using lighter materials and jettisoning optional extras that weigh the car down.

The last road to take will be the increasing adoption of PDK, twin clutch transmission that allows for a discrete saving in fuel compared to manual and automatic options. In 2009 it will already be seen on 80 percent of the vehicles sold, but in five years we should see the manual option completely disappear. The only ones saved should be the turbo, GT2 and GT3 which won’t be equipped with the current PDK, as they’ll expect the next version.
