Porsche is completing the fastest ever generation change in the 911 model series. Two new power units with Direct Fuel Injection (DFI) improve both the performance and economy of the car, the fast-shifting Porsche Doppelkupplungsgetriebe (PDK) – or double-clutch gearbox – replaces the optional Tiptronic S automatic transmission, and electronically-controlled Porsche Traction Management (PTM) takes the place of the former viscous-coupling all-wheel drive system.
The latest addition to the new generation 911 line-up comes as before in two variants; 911 Targa 4 and 911 Targa 4S. The Targa 4 version is powered by a 3.6-litre flat-six engine developing maximum output of 345 bhp (254 kW) and giving the car a top speed of 176 mph. The power unit featured in the Targa 4S displaces 3.8-litres, developing maximum output of 385 bhp (283 kW), and accelerates this outstanding sports car to a top speed of 185 mph.
As their designation implies, the 911 Targa 4 and Targa 4S remain exclusively available with four-wheel drive. For the new generation models, the all-wheel drive is now provided via electronically-controlled Porsche Traction Management (PTM), which replaces the viscous multiple-plate clutch arrangement fitted previously. The superior PTM system was first developed for the 911 Turbo and has been modified for the Targa models. The transmission delivers an even higher level of driving stability, traction and agility, further enhanced by the mechanical limited slip differential also now fitted as standard to the rear axle.
Inside the 911, the new Porsche Communication Management (PCM) centre console with its larger, touch-sensitive screen improves operation of the audio system and optional satellite navigation to an even higher standard. And a further important point is that PCM is now compatible with Bluetooth, USB and iPod requirements.
The second generation Porsche 911 Targa 4 models go on sale in Great Britain and Ireland on October 25. The Targa 4 Coupe 3.6-litre is priced from £72,980, and the Targa 4S Coupe 3.8-litre is priced from £80,270.
Fitted to every 911 is a Porsche Vehicle Tracking System (VTS), a sophisticated vehicle security package approved to Thatcham Category 5 standard, and customers will also be able to explore the potential of their new car on a Porsche Driving Experience course.
