The also used some very unique active aero enhancements - sort of like a torque vectoring differential, but using spoilers and openings to help the car turn easier/faster. From what I've read, that may be the biggest game changer.

There are some very serious doubts about the legimity of this claim and of this video.

That's pretty interesting. I wonder how accurate the speeds/recorders are in the video, but this definitely seems like more than just chance.

Hmm something stinks here

Yes.

From www.northloop.co.uk user JCviggen:

"I saw some people question this video today, as I'm pretty skeptical generally I went and wasted some time looking at it a few times, occasionally frame by frame.

And I'm pretty sure something fishy is going on, beyond the one-off tires and ECU mapping they may have used, the video itself has some inexplicable things in it when compared to the laps by the Aventador and 918.

Both the Aventador and Huracan appear to be showing GPS speeds, as the Aventador video has the GPS signal drop out for a few moments after Bergwerk (a typical place for that to happen in my experience) and the Huracan has a smaller but clearly visible loss of signal somewhere around Wippermann. Other than that the overlaid speeds seem to correspond with the dashboard almost perfectly though.

It's immediately obvious that the Aventador with its 750 horsepower hits much higher speeds than the Huracan, 297 vs 280 kph towards Sx and 321 vs 299 under the bridge at the end of the lap. This is in line with expectation as it has a lot more power and the relatively modest weight difference is not really in play much at silly high velocities where aero is everything. Minimum corner speeds aren't clearly in favour of the Huracan either. Where did it find all that time?

The only thing left to do was to use some fixed distance markers and calculate the actual speeds the cars were traveling, on average, between these points.

I used the km.4 board right after FP until the km.5 board after the hump towards Sx. At every point did the Aventador show a significantly higher speed - it passed the first board at 209 and hit a 297 high. The Huracan passed the first board at 204 and hit a 280 high. At no point between these boards did the Huracan get near the Aventador's speed. But it crossed the distance more than a tenth of a second quicker, somehow or other. I tried to give the Huracan the biggest possible margin of error with the measurements but it ended up faster than the faster car.

There are only two possibilities: one of the two speed measurements is way off (would be unusual given the evidence that suggests they were both GPS based) or the Huracan video has been sped up. Well that or the Nordschleife has shrunk slightly between these two record attempts."

Indeed.
