True that.
Show me any of the makers that doesn't play the numbers game...
Back in 2010 when Ford and GM were releasing their numbers. GM came out with 397 HP and 765 TQ. That exceeded what Ford had released, and they already had trucks on the road. Ford quickly retrenched with a nice round 400HP 800TQ, even offering a reflash to those the had already bought.
I saw a interview with some of the GM engineers, They were asked why didn't GM just make their Dmax ratings the same as Fords... The answer "We have extensivly tested the Dmax and that is what the numbers came in at. We are confident and comfortable with these numbers."
The Dmax then went on a tear in test after test easily beating the higher rated Ford PSD.
Then the truth about the ratings slowly came out.
GM was the only one that had their power numbers tested to SAE standards....
As has been said, claiming and achieving are two different things.
I remember the Chevy laying the 2011 Ford to waste on the first hill climb tests but it did it with less power. Here is a link to one of the dyno runs on the three trucks from back in 2011.
Here's a copy/past summary of that dyno run:
Regardless of which transmission gear we tested the trucks in, the power rankings were all the same. The 2011 Ford F-350 with the 6.7L Power Stroke made the most horsepower and torque, followed by the 2012 GMC Sierra 3500 with the LML 6.6L Duramax, and the new 2011 ½ Ram 3500 with the 800-lb-ft calibration came in third.
We know some of you are going to be shocked by this data (we were), but based on seven other tests we ran these three trucks through—those numbers are the real deal.
