    Great post kostby, just a small correction.  The Wayne Michigan Ford plant only produces the C-Max and Focus variants.  The Fusion is built in Flat Rock Assembly.

     

    I've slowly started to hear C-Max advertisements on the radio but they now only mention "total system horsepower."  No mention of fuel mileage.  Ford probably doesn't want to remind anyone of the MPG rating fiasco.

  2. From www.americanmuscle.com:

    What model year Mustang are you looking at?  Only the 1979 to 1993 Mustangs share the same bolt pattern.  1994 and later has a 5x114.3 bolt pattern that doesn't match up with the C-Max. 

  3. Just six weeks shy of my first year of ownership, it finally happened. I came out of the grocery store to find a scratch on the corner of my rear bumper. Of course, there was no note on my windshield from the perpetrator.

     

    The scratch is not particularly wide or long, but it has sections that are deep enough to see black on my otherwise Oxford White vehicle.  The black areas do not look like deposits left from the contact. I am guessing that these areas show something under the paint, or that this black is the base color of the plastic bumper. Fortunately, I didn't observe any damage to the actual bumper material. So, touching up the scratch should bring everything back to looking like new.

     

    I got Oxford White for a few reasons, one of them being that Oxford White does not have a clear coat. In theory, this makes touching up little scratches and chips the kind of thing that even a non-professional can do with great results. Well, I guess it is time to put this theory to the test.

     

    For such a repair, I assume that everyone would suggest using genuine Motorcraft YZ (Oxford) touch up kit. I have used a pen style kit before, and I was satisfied with that. So, I plan to use that type of kit again.

     

    In my only previous experience with trying to touch up paint myself, I started by wet sanding (1000 grit) at the direct site of the scratch, to even up the surface and to assure that the touch up paint adhered. I dabbed on from the pen, and then I very lightly and briefly wet sanded smooth after dry. 

     

    If any experts have any advice to pass along, I would greatly appreciate your input.

     

    I knew that this day would come. :sad:

    I'm pretty sure that the Oxford White still has clear coat since the clear coat is really important for UV protection for the paint.

    I've gotten a lot of rock chips on my blue candy c-max.  Luckily, they are all fairly small because the touch up can't seem to match the color of the original paint.  Or maybe I was applying it incorrectly but even though it's slightly off color/darker the chips are pretty hard to see after touching up.

  4. Just read this article that was posted on CR.  Don't usually read often from CR but a tidbit from their article is interesting.

     

     

    According to the Detroit News, a Ford representative said that owners would be able to download the new operating system to their existing cars this year or next. Hopefully the change in operating systems will eliminate the system crashes we experienced in our Ford Edge and Ford Flex and wipe out the other remaining bugs.

     

    http://www.consumerreports.org/cro/news/2014/02/ford-pairs-with-blackberry/index.htm

     

     

    I hope that part about downloading the new OS for MFT is true and I hope it doesn't apply to just the Edge and Flex.

  5. The only issue I've experienced with the navigation is on long road trips.  I drove from Michigan to Texas last December and it calculates the route just fine but when I deviate from the route (I want to take a specific route to avoid traffic or construction) the navigation keeps trying to reroute me back to the original route it had calculated.  This goes on over and over until after a while it'll give up and display a "route calculation failed" error.  This error will prevent me from inputting the same address again and calculating a new route based on my current position and route.  It didn't go away until I merged back into part of the original route or got close enough to it.  It wasn't a big issue because I've completed this trip multiple times so I know where to go but if I had never driven that route and the GPS started doing that error then a person could get lost or be forced to go back to the original calculated route.

  6. But...here's a big but...or maybe a big butt...They are going with Blackberry. Yes, that disappearing company, not say Apple. Oh, it could get worse...

     

     

    Blackberry is not doing well but QNX is a subsidiary under RIM.

     

    QNX is actually an industry leader in embedded operating systems.  Audi, BMW, VW, Chrysler/Dodge are among the manufacturers that use QNX.  This could be a good thing for Ford.  I do hope that they keep ahead with other developments when they mature (Apple and Android) but right now they are looking for stability which Microsoft has struggled to provide in MFT.

  7. It bothers me that Sync with MFT doesn't support Applink - something I only looked into and learned recently - so if that counts as a Sync complaint, then there it is.

     

    But other than that, Sync has never bothered me. I love it. In fact, Sync is one of the reasons I bought this car over a Camry Hybrid. Well, Sync and considerably more storage, so not really a fair fight, but still. It's the nicest music/nav system I've ever used.

     

    Ford was supposed to be rolling out an update that would enable Applink support.  I remember reading/hearing about it a while back but haven't heard anything else since.

  8. Don't know how long you've had your car, but the "Big Fix" last summer actually made this inaccuracy worse.  In fact, it is my theory that that was the main feature of the fix.  Indicated MPG got better but actual MPG was the same as always.   

     

    Considering how much heat Ford received from the initial EPA ratings for the C-Max, I doubt they would be stupid enough to do something like make the trip computer more inaccurate to "hide" fuel economy.

  9. Been crunched & poorly reassembled?  Oopsy, forgot the E. 

    LOL, that's a possibility that it was a defective badge.

     

    It would have made more sense if it was an "ST" badge since they build C-MAXes with all the Focus types in the same plant.

  10. comments below...

    Most of my performance tire experience also comes from autocrossing. By way of credentials, I have the complete runner-up set - 2nd, 3rd, and 4th - in H-Stock at Nationals in the 1980's to early 1990's. I ran a BMW 320iS, 1.8L 5-speed. 13x5.5" wheels and no suspenstion adjustability, so positive camber up front and negative camber, semi-trailing arm in back. I ran everything from 175/50 P7's to Yoko 008R/001R and the Goodrich autocrossers, leaving the pursuit about the time Goodrich came out with their asymetric carcasses, and dropped everyone's tire pressures 10-15 lb. That's where I see link #2 failing in the rationale side, even as he presents a functional process for optimizing pressures.

     

    Gotta run,

    Frank

    Cool, I haven't been autocrossing for very long but based further reading the increased grip on wider tires may be attributed to softer compounds vs narrower tires.  I always assumed that tires of the same models would have the same compound make-up but increasing width would provide more grip.

     

    On another note, the 225 wide tire was picked by vehicle engineers for the C-Max.  If they could put a smaller or narrower tire for increase mileage without negative impacts to driving dynamics they would have done so.  The C-Max is pretty heavy so how narrow could you go before you experience tire deformation that would negatively affect driving dynamics or mileage.  

  11. Rapier, I'd like to hear your logic, as there's a strong argument that a narrower contact patch improves braking. Pascal's Law says the contact area is equal, so a narrower contact patch must also be longer, which favors braking.

     

    And same for you, dc. How does higher tire pressure hurt traction? What's your logic, as there's again a strong argument to the contrary. Pascal's Law says that the higher PSI has a smaller contact patch, but it's carrying the same load, so the contact pressure is also increased. This gives the tread better bite into the road surface, so the net tractive force available is the same. Where you really see this is in winter driving, as modern snow tires need contact pressure to distort the tread blocks, raising edges within the tread block.

     

    Now, reducing tire section will reduce drag, and changing tire diameter will change effective gearing, but the available effect is small unless there's a lot of room for really big tires. Plus, you now need to apply correction factors, as your mileage will be a wash unless you calculate actual miles driven.

     

    But then, the only way to improve an optimized system is with a buch of little improvements that add up.

     

    HAve fun,

    Frank

     

    My logic is based on autocross/road racing experience.  With the same tire type/compound, changing to a wider tire provides more grip.  This is of course on clean dry asphalt.  The wider tire would have worse performance if the road is wet/gravel/snow etc.  This is evident in rally racing where their snow/gravel setups use narrow tires and for dry asphalt their setups use wider tires.  I found a short article that I've linked below that seems to make sense.

    Also have another link from an experienced autocross that discusses tire pressure.

     

    http://www.awdriven.net/autoX-tire-pressures.htm

     

     

    Hmm, just saw this article a short while later.  And maybe the same tire model/brand with different widths don't use the same compound.  Which is why a wider tire has more grip because it is a softer compound and has less stress/heat during braking/cornering.
