Wow, what a huge improvement over the old 6.4-liter Powerstroke. Very, very quiet, a ton more power, and super smooth. We get behind the wheel of Chevrolet's newest Duramax in a few days, and that engine has a lot to live up to in order to match the Ford's NVH characteristics, even if the Chevy is rated to tow more.
I recently sampled an F-250 with similar equipment save for the new 6.2-liter gasoline V-8 and FX4 trim goodies. I was not terribly impressed by the 6.2-liter engine or the FX4's ride quality. Perhaps that's why I was so blown away by the 6.7-liter's smoothness and the King Ranch's unladen ride. Yes, it's a big truck and it's going to ride rather rough until you load up the bed or hook up to a trailer, but it's livable for daily use. I'd probably give the nod to Dodge's 2500/Cummins combo for a daily driver that sees serious towing on weekends due to Dodge's incredible ability to make such a big truck behave so well when it's empty.
Even with tougher emissions regulations in effect and the talk of rising fuel prices surrounding the disaster in the Gulf of Mexico, there's never been a better time to buy a big diesel truck. Each entry in the market is more capable and refined than ever before. But this can't last forever. Eventually these monsters will have to be scaled back. Enjoy them while it lasts.
