It wasn’t that long ago that the Koenigsseg Agera R set a new world record for braking from 300 km/h. But already it’s been beaten by a Porsche. And what a Porsche this is. The limited and very special 911 GT3 RS 4.0 did that thing in 6.5 second, which is only a tenth of a second better than the Agera’s record, but still enough to remove the big Swede from the book of world records, at least from this chapter.

The test was conducted by German magazine Sport Auto. Check out a video of it after the jump.
