保时捷继上周末在古德伍德速度节上发布了911 GT2和Turbo S Exclusive系列两款车之后，开始准备推出另一款定位更高的车型——911 GT3 RS。最近谍照记者纽伯格林赛道附近拍到了正在测试的GT3 RS。该车采用了更多空力套装以便进一步提升性能。车头最显著变化是采用了类似GT2 RS的NACA进气口。而它的保险杠则与非GT3车型一样。车尾的后保险杠与普通GT3车型一样，而尾灯组则与老款车一样，不过，预计最终量产版会有所改变。据说该车原来搭载的4.0升水平对置六缸引擎将换成4.2升引擎，功率超过500马力。最乐观的报道是550马力，不过520-530马力应该是没问题的。伴随着功率的提升，扭矩也将增加，超过现行版的460牛米。预计该车将在9月的法兰克福车展亮相，也不排除保时捷提前在网上发布该车的可能性。

2018 Porsche 911 GT3 RS Spied Flaunting NACA Ducts

After introducing the GT2 RS and Turbo S Exclusive Series pair of showstoppers at the Goodwood Festival of Speed last weekend, Porsche is gearing up to launch yet another 911 positioned almost at the top of the food chain. Spied near the Nürburgring, the GT3 RS will once again be the beefiest naturally aspirated Nine Eleven money can buy. By the looks of things, it’s set to receive an even more aerodynamic body to further boost performance.

The most obvious change is noticeable at the front where the hood now hosts NACA air ducts in the same vein as those of the GT2 RS. As for the bumper, it now has a new look in line with the non-RS GT3. It's the same story at the back where the bumper has been carried over from the regular GT3 while the taillights belong to the pre-facelift model, but that will change when the final production car will break cover.

Rumor has it the 4.0-liter boxer flat-six engine will be enlarged to a 4.2-liter displacement and that will take output beyond the current 500 horsepower. The most optimistic reports are suggesting somewhere in the region of 550 hp, though 520-530 hp seems like a safer bet if you ask us. The expected bump in horsepower will likely be accompanied by a torque increase as well over the existing 339 pound-feet (460 Newton-meters) of torque.

We will probably see the revised GT3 RS at the Frankfurt Motor Show in September or even sooner if Porsche decides to drop some images and specs on the World Wide Web.
