Lower CO2 emissions and more powerful Porsche 911  (07/06/2008)

 

  

Acclaimed as one of the best sports cars in the world, Porsche has developed the unique rear-engined concept of the 911 continually over its 45 year evolution so that it remains relevant in changing times. The 911 is the perfect synthesis of sportiness, superior everyday versatility, all-round economy and genuine environmental compatibility. Now, by introducing a wide range of new and truly comprehensive technologies, Porsche has built on the outstanding reputation of the 911 to further optimise the car for today’s driving environment. All-new flat-six power units displacing 3.6 and 3.8-litres featuring Direct Fuel Injection (DFI), and the option of the Porsche Doppelkupplungsgetriebe (PDK) double-clutch transmission, are particular highlights marking a quantum leap in the car’s development.

The four new 911 models – two Coupés and two Cabriolets – offer increased dynamic performance and outstanding efficiency. With either a six-speed manual gearbox or the PDK transmission, the Carrera Coupé offers outstanding fuel economy of 29.4mpg combined. Furthermore, CO2 emissions of the 3.6-litre engine are down by up to 15 per cent to 225 g/km, thereby achieving VED Band F and reducing vehicle excise duty and company car taxation costs. And these engines, six kilogrammes lighter than before, also outperform EU5 emissions regulations.

Direct Fuel Injection (DFI)
Standard on the Cayenne V-engines since 2007, Porsche is now moving over to Direct Fuel Injection (DFI) for the flat-six engines in the 911 series. Forming exactly the right mixture of fuel and air directly in the combustion chamber, this sophisticated technology serves to develop more horsepower and torque from less fuel.

As well as offering lower running costs, the direct fuel injection engines fitted in the 911 are also more powerful than the previous generation power units. Maximum output of the 911 Carrera 3.6-litre is up by 20 bhp to 345 bhp (254 kW). Output of the 911 Carrera S 3.8-litre power unit is equally impressive, up by 30 bhp to 385 bhp (283 kW). With this extra power, the Carrera S Coupé now offers a top speed of slightly over 300 km/h or 188 mph.

The driver benefits from a further advantage of direct injection every time he moves the throttle pedal: with fuel being injected fractions of a second prior to combustion, the engines respond even more directly and spontaneously to even the slightest movement of the driver’s right foot. This is not only the case when accelerating, but also when lifting off the throttle, for engine speed drops more quickly and smoothly since there is no residual fuel left in the intake manifold which might otherwise prolong the combustion process.

The second generation Porsche 911 goes on sale in Great Britain and Ireland on July 5. The Carrera 3.6-litre is priced from £63,070 and the Carrera S 3.8-litre is priced from £70,360. The 911 Carrera Cabriolet is priced from £70,360, the Cabriolet Carrera S from £77,650.
