The next iteration of Porsche 991 that comes to make the job of choosing a new 911 even harder is the new Targa version, and it’s celebrating its debut at the 2014 Detroit Motor Show (NAIAS). The 2015 Porsche 911 Targa – or 991 Targa in short – is identical to the standard Carrera in every aspect, except the roof arrangement, and the fact that it only comes in AWD version.

The Targa roof on this vehicle is an homage to the original Porsche 911 Targa from the Sixties. It features an identical silver-colored B-pillar and a large and uniquely-shaped wraparound rear window. The roof is electric, and can be opened or closed at the push of a button. When opened, the roof is stowed in a cubbyhole behind the rear seats.

2015 Porsche 911 Targa can only be ordered with four-wheel-drive as a Carrera 4. However, you can choose between the 3.4 liter boxer in the Carrera 4 with 350 horsepower, and the 3.6 liter boxer in the Carrera 4S with 400 horsepower. The fact that the 991 Targa only comes as a Carrera 4 is curious, because Carrera 4, as you know, has a wider rear-end than normal models. So it could be a styling thing.

Both models can be had with a seven-speed manual transmission, or the optional dual-clutch PDK. The Targa 4 accelerates from zero to 60 mph in 4.6 seconds, while Targa 4S does the same in 4.2 seconds. The former is capable of reaching a top speed of 175 mph, and the latter 182.

Porsche has gone ahead and confirmed the pricing of the new 911 Targa as well ahead of its scheduled delivery this summer. The Targa 4 is priced at $101,600 while the 911 Targa 4S costs $116,200. There is also a $995 destination charge for both models.
