近日谍照记者拍到了2017款保时捷911 GT3无伪装照片。从照片看，新车改款符合保时捷一贯的风格，那就是外观变化很少，几乎看不出来。仔细看会发现车头进气口进行了改款，LED日间行驶灯更细窄，新车整体外观更顺滑。车尾的垂直散热孔位置更高，也更突出，保险杠底部进行了小改款。LED尾灯组造型更锐利，与911家族保持一致。总的来说，新车外观没有明显变化。主要的改变是在内部，新车配备了新的手动变速器。先前的谍照显示，在纽伯格林赛道测试的车辆配备的六速变速箱取自限量版的911R。除了手动变速器，新车还将提供PDK变速器并将搭载自然进气引擎。保时捷已经明确表示，GT3和GT3 RS不会搭载涡轮增压引擎。目前还不清楚新车究竟是搭载与现行版一样的3.8升水平对置六缸引擎还是那台更大的，取自911R的4.0升引擎。无论怎样，输出功率将超过目前的349千瓦/475马力和440牛米。如果新车搭载4.0升引擎，功率将与911R一样，这意味着GT3改款车功率将提升至368千瓦/500马力和460牛米。

2017 Porsche 911 GT3 is not shy to show discreet facelift
In typical Porsche fashion, the cosmetic tweaks brought by the imminent facelift for the 911 GT3 are on a subtle level, up to the point that some will have problems identifying the changes. Fans of the Stuttgart-based marque will however be able to spot the mildly reshaped front outer air intakes and slimmer LED daytime running lights lending the high-performance coupe a sleeker fascia.

Moving at the back, the vertical slits appear to be taller and more pronounced compared to the current model, while the lower area of the bumper has received a nip and tuck. The LED taillights will adopt a sharper design in line with the lesser members of the facelifted 911 family.

All of these minor changes have already been previewed by a 3D rendering of the model that emerged onto the web earlier this year, showing the 911 GT3 (991.2) won’t bring any significant novelties in terms of the exterior design.

That being said, something major is on the agenda: a manual gearbox. Previous spy images have shown a prototype tackling the same Nurburgring with a manual transmission, and chances are it’s going to be the six-speed ‘box found in the limited-run, sold-out 911 R. It will be available alongside the usual PDK and will work with the same naturally-aspirated engine, as Porsche has made it clear the GT3 and the hardcore GT3 RS will not switch to turbocharging.

It will be interesting to see whether the facelifted 911 GT3 will be motivated by the same flat-six 3.8-liter unit as the current car or it will get the larger 4.0-liter engine from the aforementioned 911 R. Regardless of what will happen, a bump in output over the existing 475 horsepower (349 kilowatts) and 325 pound-feet of torque (440 Newton-meters) is expected. If it will indeed get the 4.0-liter mill with the same power as in the 911 R, it means the GT3 facelift will push out a healthy 500 hp (368 kW) and 340 lb-ft (460 Nm).
