The astonishing Koenigsegg Agera RS broke the world speed record for a production vehicle on Saturday 4th November, attaining an average speed of 277.9 mph (447.2 km/h) on a (closed) public road in Nevada, USA. On hand to assist with verifying the speed was Jim Lau, Technical Director of Racelogic USA.
The car performed three runs, with a maximum speed of 284.3 mph (457.5 km/h) being reached in one direction and 271.2 mph (436.4 km/h) going the opposite way, giving the final average which is due to be ratified by Guinness as a world record.
The Racelogic equipment consisted of a VBOX 3i which logs GPS data at 100 Hz with a velocity accuracy of +/- 0.1 km/h – and which has been recognised by Guinness as acceptable test equipment in a number of automotive records. The VBOX 3i was accompanied by a VBOX Video HD2 which captured the runs with 1080p footage, synchronised with 10 Hz GPS data and real time graphical overlay.
Watch the two record-breaking speed runs below. Note how the car appears to cruise up to 200 mph before finally unleashing its potential and rocketing to the maximum – final gear isn’t even selected until it is travelling at 220 mph!
