保时捷近日开始测试新款911 GT2，该车将成为991系列911家族最新成员。从车头看，该车采用了比GT3 RS更大进气口，车尾后保险杠两侧也隐藏了散热孔，这表明该车搭载了一台涡轮增压引擎，这在GTS RS上是看不到的。另一个证明其身份的是排气尾管，测试车采用的是分列两侧的排气尾管，而GTS RS则是中置排气管。GT2将与911 Turbo搭载相同引擎，但功率进一步提升。最新款Turbo S搭载的3.8升直列六缸双涡轮引擎功率已经达到580马力，预计GT2将达到620马力。由于现在已经到了991系列911生命周期快要结束的时候，保时捷甚至有可能越过GT2直接上GT2 RS，这意味着该车功率将达到660马力，要知道，先前的GT2 RS功率就已经达到了620马力。不过，911系列车型将只提供后轮驱动，搭配七速双离合变速器，而高端版本则提供全轮驱动系统。预计911 GT2将作为2018款车型于明年发布。

 

2018 Porsche 911 GT2 spy shots

Porsche is out testing what appears to be a more extreme version of its latest 911 GT3 RS.

 

However, a number of details suggest the car is actually a mule for a new 911 GT2.Already confirmed by the 911’s chief engineer Andreas Preuninger, the new GT2 is expected to be the last member of the 991-series 911 family.

 

At the front of this particular mule we can see new intakes larger than the units on the GT3 RS. And at the rear are hidden vents at either side of the bumper, which typically indicate a turbocharged engine. These aren’t found on the GT3 RS.

 

Another key difference is the position of the exhaust tips. On the mule there is an exhaust tip at each side of the car whereas on the GT3 RS they sit at the center.

 

GT2s typically feature the same engine as the 911 Turbo but with even more power. With the latest Turbo S delivering as much as 580 horsepower from its twin-turbocharged 3.8-liter flat-6, expect the GT2 to have around 620 hp. Since we're already so late in the 991's life cycle, Porsche could even skip the GT2 and go straight to a GT2 RS, meaning we could be looking at hp in the 660 vicinity. Recall, the previous GT2 RS already came with 620 hp.

 

All of this should be directed to the rear wheels only, most likely via a 7-speed dual-clutch transmission. The four-wheel-steering system used on high-end 911 models should also feature.

 

Look for the new GT2 to debut next year, as a 2018 model.
