Does the article say why Ford won?
It's pretty vague but here is a quote:
Although the Duramax delivers stellar acceleration times at the track, it comes up short in our real-world evaluations on public roads and highways in metro Detroit.
With the trailer attached, the Duramax feels (and sounds) like it needs to work harder than the Power Stroke to do the same job. Under heavy acceleration, the Duramax sounds downright shrill.
In one back-to-back test, the Duramax needs about 2,000 rpm to tow the trailer up a moderate grade. The Power Stroke in the Super Duty conquers the same grade at the same speed at about 1,300 rpm. The Ford engine feels like it is barely working at all.
I'm not sure I'd really call it a win based on this limited info.
The sound bytes are very interesting. Does anyone else notice the drastic difference in noise between the trucks? The duramax is _by far_ the loudest of the 3. Ford is the quietest, by a long shot.
My wife didn't believe me when I told her it was quieter than her Lexus!
