For the very first time, the Targa models will be available exclusively with permanent all-wheel drive and a body that is 44mm wider at the rear.
As with their predecessor (the Type 996), the most striking feature is the large glass roof and folding rear window.
The Targa 4 is powered by the familiar flat-six engine, delivering 239 kW of power from 3.6 litres. It accelerates the car from 0 to 100 km/h in 5.3 seconds and reaches a top speed of 280 km/h.
The more powerful S variant features a 3.8-liter engine producing 261 kW. This model sprints to 100 km/h in 4.9 seconds, and has a top speed of 288 km/h.
Thanks to Porsche's VarioCam Plus valve control system, the Targa 4 develops maximum torque of 370 Nm at 4 250 r/min.
The equivalent for the S version is 400 Nm at 4 600 r/min.
Power transmission is via a six-speed manual gearbox but Porsche's five-speed Tiptronic S automatic transmission is available as an option.
According to Porsche the glass roof is not just a "visually appealing highlight" but also ensures a light, airy interior. It can be opened in only seven seconds to as much as half a meter.
