2010 Ford Shelby GT500 - Click above for high-res image gallery

While the two variants of the Ford Shelby GT500 that we've lived with since 2007 are undoubtedly fast in a straight line, they have a major flaw. They are simply too heavy. For a variety of reasons, when Ford created the GT500, they opted to use a cast iron block rather than the aluminum dry sump block that was in the GT supercar. Between that and all of the performance model's extra equipment, the GT500 is over 400 pounds heavier than the Mustang GT with most of that hanging over the front axle.

Ford has acknowledged that the Mustang will be getting updated powertrains in the coming model years and we expect at least two new engines for 2011 including the 400 horsepower, 5.0-liter Coyote V8. PickupTrucks.com is reporting that for 2012, the Coyote should spawn a twin turbo variant with over 500 hp for the GT500. With an aluminum block, this engine figures to be markedly lighter than the current engine, which ought to give the car much better handling.

Another source with knowledge of the upcoming Mustang lineup referred us to a report in AutoGuide.com and tells us "this information is very, very, accurate... ". That report says that there will be instead be an aluminum block supercharged 5.4-liter V8 in the 2011 GT500. Apparently we'll find out in due course.

      I will be interested to see what the die hard Mustang fans will say. i can't see them being happy with a TTV6 and I can see them saying that the TTV8 isn't throaty or loud enough.

      I think GT500 buyers are more concerned with looks and sound then actual performance, If it can't wake the neighbors down the street then they don't want it.

      The earlier Cobra's had alumnium 4.6 block, but these were replaced with iron blocks when they started to supercharge them. The aluminum blocks (apparantly) could not handle the power reliably. As pointed out, in addition to the iron block, the GT500 weight is addded by the supercharger, intercooler, extra belts, forged heavy duty rods and pistons, extra cooling fluids, bigger transmission, cooling systems, bigger brakes, bigger wheels and tires, etc. etc. etc.
        • 5 Years Ago
        Yea, those original aluminum teksid blocks are pretty popular with terminator cobra guys trying to reduce weight.

        The main reason Ford went to cast iron was cost. They could have produced an aluminum block GT500, but Ford didn't have the manufacturing capability to do so, which meant it would have been sent out to another company. Too expensive for what they were trying to accomplish.

        IIRC, Ford farely recently stepped up their manufacturing capability when it comes to aluminum blocks and engines. I think they did that on purpose so they don't have to rely on other manufacturers, making it much more cost effective.

        Not entirely true. The Ford GT has an Aluminum 5.4L supercharged V8. Tuners have said it is one of the stoutest engines ever put in a production car, people are making as much as 1000hp on the stock bottom end. The real factor was cost, and in a car like the GT500 the weight savings should have been more important than the cost savings. Ford wouldn't have lost a single GT500 sale if the price tag had been $1000 more.

      Dear Ford,

      please don't kill the soul of a Shelby with this garbage talk of EcoBoost V6's in a GT500. Don't listen to these "I put a dollar before the joy of driving a real car" guys. Who in their right mind of state would want a car that looks like it can eat you to have a V6 with turbos? And who cares how thirsty it is when it is already around the 20mpg range and is driven only on weekends or nights where you just want to go out for a drive? Direct inject it (as you are thinking) and make it out of aluminum (as you are thinking) and slap on a sweet supercharger on it (as you are thiking short term) with slightly wider tires in the rear. This will give you better mpg's and lower weight without putting a skirt on this car. The wider tires are just like stockings on a woman, no purpose but the one....you know. Also, please reconsider the turbos.....please! All the hope we have left in this V8less city of Detroit are our supercharged muscle cars all over the town and the joy of instant torque when coming out of the S turn on I-75 right around 9 mile. Aaaaaah, the joys of life. Turbos are great, but not Shelby great.

      Again, you have done this car so proud, don't let the guys who will never buy this car make you think that these changes will change their mind. They will still opt for the V6 vs. this and still try to explain their reasoning. Their hearts are spoiled and souls lifeless.

      My money is waiting for some weight shedding in the front and I am growing inpatient. I can't wait till the day I dance with my Shelby up and down metro Detroit with my heart finally being set straight. One has to drive a Shelby GT500 to understand its purpose, what it has to offer. I once was lost, too, but now I am found. And if any of these girly, whinny, men would like to man up, I will be more than happy to let them sit in my Shelby's passenger seat and experience their beans growing again.

      Thank you Ford, you are doing it right.

        "Turbos are great, but not Shelby great"

        Forgot about the Shelby Charger?
      • 5 Years Ago
      Would be nice to have a TT V8 Stang but then again that rarely happen's.
      • 5 Years Ago
      Why do people like putting in unnecessary apostrophes? If the "s" is there as a plural, then you don't use one. If the "s" is there for ownership, that would be the time to use it.

      Bad:
      - Both cars are no better then Mustang GT's and
      - but almost all V8's you see for racing

      Good:
      - the firmer ride is harder on the convertible's more flexible structure

      BTW you need Ford AU to make the Falcon in LHD and send it over, I love my XR6T :D
      • 5 Years Ago
      For the people knocking on twin turbos... apparently you haven't realized this, but one of the fastest American made vehicle IS a twin turbo; the Saleen S7 . As a car enthusiast, I can say, mustang people WILL NOT care whether it's a supercharger or twin turbo car as long as it has a v8.
      • 5 Years Ago
      I've heard this:

      2010 GT500: 5.4L Supercharged Iron Block V8 (540hp)
      2011 GT500: 5.4L Supercharged Aluminum Block V8 (540-550hp)
      2013 GT500: 5.0L Twin Turbo Aluminum Block V8 (600hp+)

      Sounds good to me.

        FoMoCo sold over 114,000 cars in September, and maybe 200 or 300 of those where GT500s. The thing could get 5mpg and it wouldn't even cause a noticeable blip in their CAFE rating.
      • 5 Years Ago
      The difference in weight between aluminium and cast iron V8 block is about 50lb. It is not the engine block materials that are resposible for the 400lb difference between GT and GT500, but the strengthen/enlarged components of the GT500, needed to handle the increase in power.

      What's worse is that the turbo DOHC V8 with aluminium block, that everybody seems to be pushing for, is not going to be lighter or consume less than the supercharged SOHC V8 with iron block (and I'm talking here about the new supercharger found on 2010 GT500, not the old one). But is certain that the turbo DOHC V8 is going to be way more expensive for no benefit - that should make everybody happy.
        • 5 Years Ago
        You're right, the engine is DOHC not SOHC. On the other hand, it could have been SOHC and still get the same power, it's not like a 6000rpm redline asked for a DOHC.

        About the turbo, yes I'm sure the turbo gear and piping weigh significantly more than the supercharger. Turbo gear and piping weigh more than 100lb on R35 GT-R, for an engine that produces less than 500hp. The supercharger gear on GT500 is under 50lb.

      i have heard the aluminum SC 5.4 is a go for at least 2 years

      ecoboost v8 down the road a bit

      Why is it that Ford is worried about this or that engine in a 500hp, 40-50K Mustang... It is good for those few buyers... who have a Terminator Cobra, or an earlier Shelby, and want to upgrade... but is this car really conquering new buyers from other brands?

      Maybe if ford built something with this criteria...

      4-wheel independent suspension
      RWD, perhaps with optional AWD.
      Mid-size 3-door 2+2 coupe, and 5-door sedan pairing.
      3300-3600lbs curb weight, depending on body style and options.
      across the board availability of either manual or dual-clutch automated gearboxes, not just bare-bones, or no manual at all...
      ~28-38K price point, depending on options, with a good, diverse options list.

      Modern styling and amenities inside and out... even if it has a couple of traditional cues, not a retro car. A MODERN car, for someone who wants to live in the NOW, not relive the glory days that some of us weren't even around for.

      I don't care if they call it a Lincoln, although I think it would be better to use it to REVITALIZE MERCURY.

      Engine options could range from a 3.7 NA V6, to an EcoBoost TT V6, or a Coyote V8, super or turbocharged V8 special model, a light-weight RS model with a turbo 4, even. Whatever.

      Why isn't such a car even a blip on FoMoCo's radar? Not a T-bird, not a Cougar or Capri, or Comet, not an MKR or Mark IX... NOTHING.

      It isn't as if GM or ChryCo have alternatives to a mid-life-crisis-mobile, either.

      What the hell happened to diversification?
        • 5 Years Ago
        So, you want a 4 person Z06 that costs what a Fusion costs.

        Good luck with that.

        Heck, while your are at it, why don't you wish for 500hp and 40mpg combined also. That is just as likely.

        By the time you used the exotic materials to build this incredibly lightweight car with AWD, that meets or exceeds all 2012 regulations, you would be looking at $50-75K. Otherwise, the automaker would lose their ass on every one sold. However, they would make it up in volume.............. right?? (sarcasm)

        You know, I want a 3500sq ft real log home, with every luxury amenity available, and I am generously willing to pay $150K for it. Somehow, while I understand that the demand would be huge for such a home, I just don't see my wishes being realistic.
        • 5 Years Ago
        It's called the Ford Falcon and it lives down under. I grit my frikkin teeth thinking about it.
        • 5 Years Ago
        I would not hold my breath waiting for such a car from Ford. I grew up in a Detroit suburb with Ford cars and a father who was an engineer at Ford. I've owned my share of Mustangs, and loved them. But I later switched to BMW in search of something new - with the same attributes you are listing here. Honestly, I would go check out the 335i if I were you because it has everything you want, including falling within that price-range if you do European Delivery and don't go wild with options. This is exactly what my wife and I did a couple years ago. Guaranteed not to dissappoint.

        That said, your best bet if you do not want to stray from the big 3 would be to wait for the upcoming ATS. I have high hopes for that one myself. But, getting back on topic, I also have high hopes for this new Coyote V8. Between the new '10 styling and the new engines coming, the Mustang has caught my eye for the first time in seven years.
        • 5 Years Ago
        "why doesn't Ford build a car that follows this very specific set of criteria that I have just stated?"

        Lord only knows.

        BTW Ford sells buttloads of mustangs stateside and a Mustang GT weighs 3,500lbs. Your subaru would probably weigh more with the bigger engine.

        As for looks, mustang sales took off as soon as the retro model first came so I'm pretty sure your in the minority in thinking it's an unattractive car.
        • 5 Years Ago
        Gloria...

        You are wrong. My Subaru, aside from being a 4-door and having a smaller engine, fits most of those qualities, without exotic materials, with AWD, and weighs 3480lbs curb weight, with LEATHER. A current Genesis 3.8 Touring Coupe is not far off, either.

        3300-3600lbs is AVERAGE, not light weight. Just because the retro triplets are heavy as hell, doesn't mean they have to be. That isn't far off Mustang GT's curb weight, and that is an overly bulky car with lots of exterior sheet metal.

        I didn't say it needed to have a Shelby-grade engine for $30K. I listed a lot of different engine options.

        Your over-the top hyperbole is your prerogative, but it isn't even close to reality, and is just a list of inflated excuses for Ford to continue NOT to compete for new buyers.

        Just relying on the other two of the "big 3" to suck harder, to give you better marketshare is not a good plan.

        I have also owned a Mustang before... a Fox-body, and it was a fine car for it's day... and it was much lighter, and it was modern for most of it's model years... except maybe a bit long in the tooth by the early 90s, having started in 1979. SN95 and new-edge did nothing to help, and S917 and '10+ haven't either.

        No hatchback, although it looks like it should have one... No real-world crappy-pavement-tolerant IRS... And it is not living in the now with it's available options list, either. I like the glass roof... but that and color-changing dash-board are not enough to attract me to a car that should offer more for being a decade into the 21st century...

        I don't want a car that makes the high-school kids, and the middle-aged men turn their heads. I don't care.

        I want a car that is superior in driving dynamics, and modern throughout, at a high-value price point. Something that looks, feels, and drives well enough to make me want to part with my hard earned money, and park it in my garage...

        I want it to turn MY head, and I want it to respond well to my driving... I don't drive cars for other people's appreciation, which seems to be about the only purpose for the retro triplets, to show off to others.

      • 5 Years Ago
      Oh and one more thing...give customers the option of the Track Pack on Convertible models please!
        • 5 Years Ago
        There's one very good reason why the Track Pack isn't offered on the droptop: the firmer ride is harder on the convertible's more flexible structure.

        I had the pleasure of renting a 2010 convertible a couple of months ago, and I'll vouch for that flexibility; even on a car with less than 3,000 km, the cowl shake was noticible.
