Does anyone have information about independent dyno tests of the F12berlinetta? I read in another forum that one was dyno'ed and found to make around 680 horses at the crank—which would obviously be a bit of a letdown—but there wasn't any associated link or evidence.

Links to actual charts or other pages with the data would be ideal, but I'll take accounts of seeing a car on the dyno that's all you have.

 

Really.. for what? The car is very seriously fast , you worried they fluffed the HP output? My friend has one it is so fast its beyond insane and he has a 991 Turbo S, an MP4 and an Aventador.

 

I'm looking for independent confirmation. Ferrari has been rumored to play fast and loose with things like engine outputs before. I know it's fast, but multiple tests have found that it's not as quick as it should be. I'd like to see some facts, evidence, data.

 

Where have you heard or read that its not as quick as it should be? I haven't seen any reports either online about that other than your comment. It seems to me that when you make a comment like "Ferrari has been rumoured to play fast and loose with things like engine outputs before", you're talking about ancient history as every car manufacturer used to do that in the 60's and 70's, but not recently Ferrari included. Seems like just another post from a Ferrari hater to me, of which there are far too many on Teamspeed

 

The first report came from Motor Trend, where the car was barely faster than a 460 horsepower Corvette Stingray: 2014 Ferrari F12 Berlinetta Exclusive First Test - Motor Trend

The dyno test was from Portland Speed Industries:
And the reports of engine output variance come from a wide variety of sources, but largely from firsthand accounts on forums that people's Ferraris aren't quite as quick as they should have been, as well as sources like Chris Harris's now-infamous Ferrari rant: How Ferrari Spins

I'm a big Ferrari fan, and I want their cars to live up to their performance potential; at the same time, I don't want to believe the company is actively lying about their cars' performance, so I'm trying to gather facts. Nothing hateful about it. Please don't jump to that assumption just because I'm looking into it.

 

Ok I understand now. Now you've got me curious too. I have noticed how done publications list the hp at 731 while others at 740?

 

740PS and 731Bhp are the same...

 

Is it possible 585 WHP equivalent to 740 PS or 731 BHP? Obviously this is a different type of measurement because it measure hp at the wheel. Seems like quite a difference and it would be interesting to have an explanation for that
