Since Ford is replacing the entire engine lineup for the 2011 F-150 pickup trucks, it has apparently decided not to reinstall at least one component that is usually bolted to those engines: the hydraulic power steering pump. According to PickupTrucks.com, the updated models will be the first full-size trucks to use electric power steering (EPAS) almost across the board.

Previously, the only full-size trucks equipped with EPAS were the General Motors two-mode hybrid pickups and SUVs. These machines powered the system from the 42 volts available as an off-shoot of the high-voltage battery. All F-150s powered by the 3.7-liter V6, 3.5-liter Ecoboost and 5.0-liter V8 will use the on-demand, electric motor-driven steering assist in place of the traditional, always-on hydraulic system. Only the specialty Raptor and Harley-Davidson models with the larger, heavier 6.2-liter V8 will retain the old system. EPAS is expected to contribute a fuel efficiency improvement of up to four percent thanks to the reduced parasitic losses.

      It's at least something. Most of the people who post on here on a regular basis cry and cry, but I bet all of you use plastic derived from oil, fuels of some sort derived from oil, home electricity derived from coal, etc. Anthropogenic climate change has never been proven, nor is the debate over amongst scientists. Instead of constantly crying on these forums and making generalizations about everyone who doesn't agree with your politics, how about doing something useful? Design an all electric vehicle that's solar powered. Design a better battery. Do something other than just turn your nose up at everything that isn't a perfect solution in your opinions. Companies like Ford are huge. They cannot just throw away a century of tried and true technology for a fringe market. Will electric someday be the mainstream market? Quite possibly. It's also just as likely that a bio-derived artificial fuel that combusts but isn't polluting will be invented, thus saving a century of work from being thrown out. In truth, I figure that the future will have many transportation options available to suit different markets, and that the one size fits all way of making cars and trucks of today will largely go away. Regardless of how it goes, it won't happen over night. It will take years to prove newer technologies, both in terms of function and in terms of marketability. Companies exist to create wealth. They're not the stewards of society that people seem to think that they are these days. Companies like Ford have helped the U.S. economy to give us the standard of living that we enjoy today. Things like computers, electrified cities, the Internet, etc. all are possible because of the vast amounts of wealth created by free enterprise. Be patient. The technology will shift.

        Come on D.
        The "debate" was over 20 years ago.
        Now, we get to enjoy the fruits of the propaganda industry, funded by Exxon and the Koch brothers. We get to watch Russia BURN, and Pakistan FLOOD, as was described in the climate models, but, that's just This Year.

        Next Year, will it be our whole southern farmers that get burned?
        Will we have to ration food?

        Here's your homework assignment:
        Correlate: Population growth for the last 200 years, the industrial revolution, now the global industrial revolution and man's carbon output. You get matching graphs.

        Here's the word of the day: Incentive: The Oil Industry has No Incentive to adjust to peak oil, or global warming, the US balance of trade deficit. The Oil Industry has every incentive to do nothing. They will make a fortune while they destroy the US and the World.

        This is truly the Monopoly Generation. They will win, and win big, with a Ton of worthless money.

        Sad, but true!

      Let me get this straight....you lose electric power and you lose your steering.
      Is that Right? If so.......I don't want one
        • 4 Years Ago
        Of all the problems a car can have, a total electrical failure is pretty low on the probability list.


        looks at it another way, with hydraulic steering, if your engine dies you loose PS boost. With electric steering if your engine dies, you still have the battery to run your powersteering.




        Now if a meteor crashes into your head while driving...
        • 4 Years Ago
        you also lose engine power ( ignition ), transmission power ( modern automatics are electronically controlled ) so i'd be worried about more than steering if your power went out!!!

        I'd even go so far as to say that an electric power steering system ( if designed properly ) is safer because it can eliminate power steering fluid, which is just another potential leak waiting to happen.
        • 4 Years Ago
        You still have steering, just not power steering. The same as if your engine stalls or your power steering pump fails with regular hydraulic power steering.

      now we can say that an F-150 is a green vehicle. now we can call off peak oil and global warming : )
      wow, way to go Ford.
        • 4 Years Ago
        Who said it was a green vehicle?

        But hey, its better than anything Toyota has done with the Tundra. That and the Titan are about the thirstiest trucks in that class.

      A 4% improvement is a Joke, with Global Climate Change making rapid destructive progress across the globe.

      FORD is still in no position to survive another oil price spike.

        • 4 Years Ago
        I own a little bit of FORD.
        I don't have a stake in anyone else.
        The small shareholder has no say against the OIL Company stake.
        • 4 Years Ago
        Only Ford?

        You seem to be extra hard on them.
        What about those other 50+ auto companies?

        "A 4% improvement is a Joke"

        4% for a change like that is impressive (if it's true). Embrace small improvements. They add up.
      • 4 Years Ago
      come on people! 4% is HUGE for a simple change like this. Some of you guys are nuts with your "all or nothing" approach to improving transportation efficiency. Look, I build EVs, and I want to buy an EV as my first vehicle, but the fact is that most people buy with their eye on their pocket book. You can't expect a company to make a product that isn't going to be profitable, and I'm sorry, but fuel prices where they are, people simply aren't willing to pay that much for improved fuel economy. Don't bitch and moan at the company, direct your frustration at the people buying the vehicles they want, and the backwards attitude that prevents anybody in power from ever being able to increase the gas tax.

      Building the greenest car in the world isn't going to do ANY good if nobody buys it. These guys just figured out how to improve the economy by FOUR percent on the NUMBER ONE SELLING VEHICLE IN THE US. Half a million F150's running at 19mpg instead of 18mpg for 15,000 miles each would save 22 MILLION gallons of fuel.

        Bravo, Jeff!

        There are economic realities that drive all these decisions, and the worlds end just doesn't figure into that calculation. The sooner we realize that, the more effectively we can deal.
        • 4 Years Ago
        4% is huge, probably a misprint and the real savings is 0.4%

        I will leave to others the calculation of how much gas (4%) it would save in an F150 every year, and how far you could drive a Prius with it..

        The way I see it, no mo worries about leaking fluid or worn out PS belt.
        • 4 Years Ago
        Never mind the extremist hardliners.
        +1 for you.
      • 4 Years Ago
      It should have been a hybrid already.
        • 4 Years Ago
        GM did that and it didn't go over well.
