Not sure how they actually tested these other cars but, there is no way in hell that a Aventador cut a 0-60 in 2.6, along with the Audi, I have also never seen a Stock GTR launch anywhere close to a TTS.

 

Agree, goes with all that I would expect from stats from Motortrend, a load of BS.
The times are insane, I've never seen times that low tested anywhere.

 

Agree 100 percent

 

The turbo seems to typically run a 1.5 60'. GTR's ~1.6.

 

I didn't see anything in there about how they derived the speeds and times. They list longitudinal acceleration in g's so I suspect they may have used an accelerometer and integrated time vs acceleration to get speed. If they used Vbox then they may be listing 1 ft roll out times from the vboxverify site which are always quicker.

What I have noticed in my use of the AP data is that the speed measurement accuracy is too rough to make good computations/estimates of anything but 60ft ET. The speed is listed by the AP to the mph, while time is reported to milliseconds. The problem is that any integration rule is going to interpolate a no slop line between points where the speed is actually changing by tenths or hundredths of a mph but doesn't change in the ones column. In other words 124.9 mph is listed as 124mph and 124.5mph is listed as 124mph. The error in distance after second gear is exited begins to get fairly large. The disagreement between Vboxverify and integrating time vs speed using AP data is always to the low side using the AP data, which is exactly to be expected.

So these numbers depend entirely on the accuracy of the instruments used to make the measurements from which they are derived. I didn't see any discussion of that in the article. It's marketing hype put out by non-engineers.
