Shoving off 26 secs from the regular aventador with 40hp more and 40kgs less and some aero is hard for me to believe.. Yes there's a video, but it doesn't sound logic.. (Flamesuit on).

Lambo claims 170% more downforce at the rear (that's almost 3 times more?!!!!!!), thanks to this wing and some vents?



But yes it's SEXY! Believe it or not, number 001/600 is in Beirut!

That is an interesting point! In the article it says the BHP is upped by 49, weight reduced by about 90 pounds and rear wing downforce was upped by 110 pound's. The driver was Lamborghini's Hot Shoe Marco Mapelli.

Now who drove the original Aventador at the ring, if it was Marco then that would be a proper comparison? Using different driver's is an Apple's to Orange's comparison!

But I do agree with what the observation the OP brought up. Are the improvement's Lamborghini able to shave 26 second's off the original Aventador's time? The proof is in the pudding with the posted Video there is no denying it. But I just want to know who was driving the original and if their was any extraneous things going on that day of it's testing; did Lamborghini have the whole track to themselves during testing like they did with the SV?

However with the 750 horsepower and the lightening of the car and the added 110 pounds of down force in the back I could see what obviously happened (it's in the video - in court that is tantamount to the truth). And for increasing the rear's ability to stay planted to the ground help's with driver's confidence. Marco is for sure a stud for pulling that time off. I love watching the video on youtube and hearing all the greeking and scrapes on the track `tis a wondrous sound.

Perhaps due to special tires? Lamborghini did not disclose what tires were on the SV. Does anybody know?

Compared to the Lamborghini, the 918 is faster in a straight line (7.2 versus 8.6 sec to 200 km/h), ~100kg lighter, has more downforce, and 4-wheel steering.

BTW, my information is that the 918 is capable of ~6:50 in production spec, as Porsche significantly improved the performance of the 918 subsequent to the 6:57 Nurburgring record. Also, see the quote from Wolfgang Hatz near the end of this article - http://blog.caranddriver.com/nurburg...tion-car-king/

The article states that: "The stock Lamborghini in the video was wearing Pirelli’s latest P Zero Corsa street tires"

A couple of years back, Nissan claimed street tires on the GTR, but they later discovered they were using race tires.. So yeah automakers would do anything!

Well there ya go for atleast one Variable. Slap those same Parelli's that the SP was using and see how much quicker the time would have been. Probably good for 5 to 8-10 'second's on such a large/long track?

Wonder if MPSS would do just as good? The Italian's are very Patriotic so one must expect it's always going to be Pirellis for their cars even though on the street the Michelin MPSS tires are the tire to have.

What is Pirelli's top tire at the moment for the street the Trofeo R or P Zero?

In a straightline the 918 is faster than everything else out there with launch control on up until a quarter mile or there abouts. Zero to 60 2.2 seconds. Faster than P1 to the quarter. Three for six against a Bugatti in a quarter without launch control on.

Given that neither Pirelli nor Lamborghini have released any information on the tires or even spec of the car - and it would only help them to state the car was on production tires and production spec, I am doubtful about how close to stock the SV was.

Also there is this...
"In the car that attacked the Nürburgring, it was also wearing very special - and, we imagine, very sticky - development Pirelli P Zero Corsa tyres. It’s unclear yet whether this will be the rubber offered on the production Aventador SV"

One last thing, all the reviews i've watched until now have surely mentioned improved handling over the regular aventador, but have also mentioned understeer! So handling wasn't praised as much as power was...

(OT: btw, its amazing how not one single review i've watched of the 991GT3 mentionned understeer!!)

Must be that rear wheel stearing helping that out.
