EPS – Again

I had to take the ’08 135i in to the dealer for routine service this week and had an opportunity to say hello and talk to the sales manager. If anyone has the pulse of what’s working at a car dealership, it had better be the sales manager. And this sales manager says the new 5 is selling well.

I asked how the customers were taking to the electric power steering and had there been any feedback about it. He told me that I was much more attuned to that than the normal customer. Well maybe, but I suspect most readers of BMWBLOG could feel the difference between an EPS rack and a hydraulic rack.

So, the question of the week; do the friends you talk to regularly know the difference? (And just to dredge up an article using the way-back machine)

The Spun Bearing: Electric Power Steering (Again?!), Fuel Cells, and BMW Holiday Giveaway

Fuel Cells

There’s news that GM and BMW have entered an agreement to cooperate on fuel cell technology. In exchange for funding, GM will share their research on fuel cells with BMW. If I remember correctly, GM has been pursuing fuel cells for some time and at one time was working with Ballard Power Systems.

Fuel cells take in hydrogen and oxygen, run them through a catalyst and spit out spare electrons (electricity) and water – and, depending on the source of the hydrogen, some other emissions. The choice of catalyst influences the efficiency of the fuel cell and the operating temperatures (which generally range from hot to extremely hot). A single fuel cell wont do the trick – so they are combined into stacks to provide the appropriate amount of power.

Ballard has a number of fuel cell stacks available (their website is:http://www.ballard.com). What is interesting is they split off their automotive work in 2008 into a subsidiary. The quote from their 2011 annual report is telling: “The purpose of the AFCC Transaction was to decrease our investment in automotive fuel cell research and development due to its high cost, uncertainties surrounding government mandates relating to the adoption and deployment of automotive fuel cell powered vehicles, the lengthening timeline to automotive fuel cell commercialization, and the negative impact of these factors on our production volumes and revenues.”

From an electric vehicle perspective, the fuel cell replaces the batteries. That means their energy density has to be better (or they have to be substantially cheaper) than existing or near-horizon battery technology in order to be useful. There is also the issue of how best to supply the hydrogen. Containing a given mass of hydrogen is much more difficult than say a similar mass of gasoline (but the hydrogen, believe it or not is safer than the gas – once pressurization is taken out of the equation).

Don’t expect a fuel cell breakthrough in the short term, based on what can ascertained, the technology is not at the tipping point for automotive applications. What this pact between GM and BMW tells us is that GM is strapped for research funding and BMW is not.

Oh, as an aside, BMW does have some experience with hydrogen fuel cells. They are using fuel cell powered fork lifts at the Spartanburg, SC plant. One aspect of the fuel cell fork lift that beats the battery powered unit, is that the fuel cell unit produces full power until it runs out of ‘fuel’, unlike the battery powered devices which can get sluggish as they discharge. The fuel cells used in the BMW Spartanburg plant come from Plug Power, their website is: http://www.plugpower.com/Home.aspx

Here’s a video discussing the use of the fuel cells:

    my father has a 2011 535xi and, this crazy electric PS, I dont like it. I will NEVER have a BMW or any car with electric PS.

    • Tyrol

      535xi should not even be with electic steering. X-drive models are with excellent hydraulic powersteering.

      • former BMW user

        xDrive F10′s do have hydraulic power steering, BUT it is set up very “loose” and not significantly better than EPS, and is still significantly worse than on E60 models. If you think that F10′s power steering (doesn’t matter if it’s xDrive model or not) is “excellent”, you’re either in denial, a paid BMW’s marketing “plant” or a fail troll.

    What don’t you like about “crazy electric PS”?

  • bmw

    my dad also has an 2011 535i and the electric steering SUCKS!  

  • Tom

    My problem with the electric PS is the system seems too dynamic and is constantly trying to compensate/correct for the speed of the car. There were times during high speed turns where I was surprised by how much boost was in the system such that the slightest turn of the wheel resulted in way too much turning.

    • Guest

      I have to agree. I want to drive a car that is predictable and handles well. When you lose the predictability, you lose confidence in the car.

  • Bmwguy2239

    The 2012 5′s eps seem different when you change the driving dynamics control to sport or comfort and they have a new mode comfort plus. I recently drove one and I think the steering in sport mode is really nice and more direct.
