Porsche 911 GT3 RS Detailed

PDK Only; Likely Wide-Body from Turbo

In case any Porschephiles have lingering doubts about the PDK twin-clutch automated transmission, the GT3 RS coming to dealers in the later half of 2014 will be unavailable with a manual. A manual would be too expensive to develop, and anyway, the new electronic differential needs the PDK's hydraulic pump to function. Read about the standard 911 GT3 (pictured), which also comes only with the Porsche Doppelkupplung transmission, here. The standard GT3 will go on sale in the U.S. this November.

Other hints about the new RS gleaned from the standard GT3 drive include the likelihood it will have a carbon-fiber roof panel, among other curb weight-reducing features. The "base" 911 is built with a modular roof panel, so the easy ability to add this feature is built in to the car's construction.

The 911 GT3 comes with the Carrera 4's wider body, making it the first not to use the narrower, Carrera 2 bodyshell. The GT3 RS is expected to take that further by using the extra-wide 911 Turbo body, which is about an inch wider than the GT3/Carrera 4 body. We also expect the RS to get a shorter final drive for tighter gear ratios, additional aero features, including an adjustable rear wing, and stiffer, more focused suspension tuning.

Porsche's engine choice remains unclear. The RS could get the 4.0-liter flat six, or it may get the GT3's 3.8-liter with some mild tweaking for more power. If Porsche goes with the latter, look for the 4.0 to appear in something beyond the GT3 RS.
