2015 Porsche 911 GT3 RS spied ahead of late summer debut, lighter and more powerful than before

This is our first look at the Porsche 911 GT3 RS as our spies spotted this prototype testing in minimal camouflage in Germany. The images give us a good indication that the extreme version of the 991 GT3 is still on course for a late summer arrival.

Based on the standard GT3, Porsche has made several visual changes to the car's design. Most notably, the RS model will feature a wider track than the regular car, meaning the front and rear bodywork has been stretched slightly. There’s also a more pronounced front splitter and a subtle new headlight desing.

Further back, Porsche has added side air vents just in front of the wheel arches, a new rear diffuser and a huge rear wing. The aero package should help increase downforce by up to 50 per cent over the standard GT3. Front spoiler winglets similar to those found on the 997 4.0 GT3 RS also appear to have been added, with a significant drop in ride height noticeable, too 

Like the GT3, the RS is expected to come with a PDK automatic gearbox only, but there are rumours Porsche is considering fitting a traditional six-speed manual transmission but as yet there is no official comment on this. Power will come from Porsche’s 3.8-litre flat-six engine, tuned slightly to increase the current 469bhp output nearer to 500bhp.

The sprint from 0-62mph should be significantly faster than the standard GT3’s 3.5 second dash but a slightly reduced top speed is expected, as a result of the increased downforce.
