Compared to the 0-100 km/h time of 4.7 sec and 4.5 time of the facelifted Carrera and Carrera S, respectively, with PDK trans, the heavier 911 Targa 4 accelerates to 100 km/h in 5.0 seconds while the Targa 4S does it in 4.7 seconds.

After the facelifted Carrera and Carrera 4 debuts, Porsche is following up with the 911 Targa facelift. Available in the same variants and 997 facelift upgrades, the 911 Targa 4 and Targa 4S feature more powerful direct injection engines, PTM Porsche Traction Management replacing all-wheel drive and Porsche's new 7-speed Doppelkupplungsgetriebe or double-clutch gearbox.

The visual highlight of the 911 Targa, as before, is the 1.54-square-metre glass roof made up of two segments, the elegant sliding roof at the front and the tailgate. When opened completely, the roof slides within seven seconds beneath the tailgate, offering an open space above the passenger compartment of 0.45 square metres. The sliding roof comes as standard with a new sunblind offering even greater privacy than before and, when closed, covering the entire area of the sliding roof and opening and closing electrically independently of the roof itself. The glass roof and the tailgate come in special anti-sunglare glass, protecting the occupants even in bright sunshine from UV radiation and excessive heat.

Compared to the 0-100 km/h time of 4.7 sec and 4.5 time of the facelifted Carrera and Carrera S, respectively, with PDK trans, the heavier 911 Targa 4 accelerates to 100 km/h in 5.0 seconds while the Targa 4S does it in 4.7 seconds.

Top speed is also a little slower of 289 km/h (179 mph) for the base Carrera while the Targa S is 284 km/h (176 mph). Carrerra S top speed is 302 km/h (187 mph) and the Targa 4S notches slight below at 297 km/h (184 mph).

Expect market launch and pricing information to be released after its October public debut in Paris.
