Always loved seeing small bit of engineering insight such as this which covers a vital part about how the engine runs efficiently.

“We know that diesels with electric cooling fans have to dial back on power under extreme heat and altitude, so we decided on a viscous-controlled mechanical fan that has the capacity to move much more air across the radiator and intercooler in extreme conditions,” said David Ives, Ford diesel engine technical specialist. “This gives F-150 Power Stroke owners more power and more passing capability in harsh conditions.”

autoweek has always been a good source for this kind of information.

I'd assume they would add more air vents as well to increase air flow into the engine compartment, but that doesn't seem to be the case.

That just goes to show how much more life is left in these gasoline engines. But then again with all the oil left around the world and whatever else is out there left to discover I doubt we will see gasoline cars get phased out so soon. That's an F-150 I would buy.

Those are some pretty impressive figures for sure. It's impressive what automakers have been able to achieve in terms of finding a balance between fuel efficiency and power output in full size pickups. I guess there's a good reason why the F150 is America's best selling truck. Wonder how much different the real world numbers will be once people get them on the road.

Just head that GM is planning to come out with carbon fiber beds which is a massive step forward. Anything to improve power to weight ratio in some of the heaviest passenger vehicles we can buy goes a long way. Too bad it might be another decade before we see carbon fiber used in the frame and overall structure.
