I actually believe the 2014 Turbo S is quicker to 300 kmh than the LP610-4 in a side to side drag race (link here)

At the end of the 1/4 mile, the Porsche trap speed was 2.03 kmh lower. At the end of the standing 1km, the Porsche trap speed was 0.6 kmh lower.
It took 8.942 seconds for the Porsche to do 206.36 kmh-266.46 kmh (progression of 60.1 kmh in 8.942 seconds).
It took 8.921 seconds for the LP610-4 to do 208.39 kmh-267.06 kmh (progression of 58.67 kmh in 8.921 seconds).
You can see that while being just 0.021 seconds behind, it managed to pull 1.43 kmh more than the Huracan, in the progress of 402-1000m. Like it or not, it closed the gap in speed, and if it was 1 mile, I would say the Porsche would have trapped higher
