No  manufacturer, not even performance orientated Porsche, can ignore the  "green wave" that has hit the automotive industry. With hybrids and EVs  becoming increasingly popular, it's clear that sports cars have to step  it up a notch.
It  doesn't really matter to pencil-pushing government officials that, in  the real world, high performance vehicles aren't driven as much, so, in  the overall scheme of things, they actually pollute a lot less than your  suburban folk's Prius. They just want to see numbers.
So,  Porsche is going greener with each new model it is launching, the  Cayenne being the vanguard of this effort. The Germans achieved  significant fuel savings in the New European Driving Cycle (or NEDC),  ranging from 13 to 23% for all available model series in comparison with  their predecessors. This means all Porsches using naturally aspirated  engines consume 0.5 to 0.6 less liters of fuel per 100 km.
The  Stuttgart firm's engineers achieved this by switching over to direct  fuel injection and adopting newer transmissions like the PDK dual-clutch  auto and the Tiptronic S eight-speed automatic. Other measures taken to  make Porsche as green as ever are massive weight savings (i.e. 185  kg/408 lbs for the new Cayenne Turbo) - and we'll be seeing more of that  in future models.
The  911 Carrera with PDK consumes only 9.8 lt/100 km (24 US mpg), while the  Boxster S and the Cayman S do with 9.4 liters per 100km (25 US mpg).
The Cayenne  is even more frugal, with the Cayenne S Hybrid really shining on this  task. Good for a total output of 380 hp (283 kW), Porsche's hybrid is  almost as powerful as the previous generation Cayenne S (385 hp/287 kW),  yet it returns a combined 8.2 lt/100 km (28.7 US mpg) representing a  40% gain in fuel economy with CO2 emissions of 200 g/km. Wealthy  tree-huggers rejoice.
