Last September, the Koenigsegg Agera R entered the Guinness Book of Records withsix amazing records . Unfortunately for the mighty Swedish supercar, one of those six world records - the fastest brake time - has already been smashed. If you remember, the Agera R went from 300 km/h (186 mph) to 0 in 6.66 seconds.
But now, a Porsche 911 GT3 RS 4.0 managed to eclipse that number after posting a time of just 6.5 seconds from its high-speed performance 0-300-0 test at the annual Sport Auto event in Papenburg, Germany. That number is 0.16 seconds faster than the Agera R.
For those of you who have forgotten the GT3 RS 4.0 is powered by a naturally-aspirated 4.0-liter engine that delivers a total of 500 HP at 8,250 rpm and 339 lb-ft of torque, which is a 50 HP and 22 lb-ft increase over the current GT3 RS model.
