BMW Introduces GINA Concept Car, Covered In Fabric 347

smithtuna33 writes "Ever wondered what the metal skin on your car is actually good for? Engineers at BMW have decided that fabric might work just as well. The doors literally peel away from the side of the car, the engine bay opens up down the middle, and pretty much everything (such as headlamps) is hidden until the fabric reveals it. It is a stunning concept that has already been influencing BMW's designs. The video is well worth watching."

        What you're suggesting is the fabric analog of getting keyed. I imagine repairing a tear caused by a key, or a pocketknife, or a rock on the freeway, would be a lot less expensive if the repair consists only of replacing a piece of fabric.

        I'm more concerned about security. Would this feature make it easier to break into my car? Would it make it easier to sabotage or steal from my engine? My gas tank?

          I see a lot of people talking about the sturdiness of said fabric, but noone mentions that it's some space-age stuff they're slapping on there, on a metal frame, laced with carbon for extra strengthening.

        There are already plenty of fabrics which are resistant to casual slashes, and some in the pipeline which are even more durable [slashdot.org].

        Vandals can already do a significant amount of damage to a painted metal car body with a knife or even a coin. If the repair costs of the fabric are competitive with metal, it might even reduce costs over the life of the vehicle.

          German cars: Drivers are super-aggressive. They drive fast and push the car to its limits. Ignore them and they will accelerate away. Usually equipped with electronic countermeasures. If a German car is speeding, you can too. Never pass a German car. If it's going slow enough for you to keep up, there must be a reason. The German car driver is a fanatic -- willing to tolerate any amount of maintenance expense because of the joy of driving on those days when the car works properly.

          Japanese cars: Drivers THINK they have a German car, when in fact they don't. These people have an inferiority complex -- anxious to prove that their Honda Accord is a drop-in replacement for a BMW 745LI, while secretly planning to buy a BMW next time. Well known taking risks that the German car drivers cannot afford to take. If you are passed at high speed by a Japanese car, rest assured they will draw out whatever law enforcement might be around. Be prepared to call 911 on your cell for an ambulance.

          Korean cars: These people are trying to optimize the Total Cost of Ownership. They don't enjoy driving very much, but they spend very little money doing it. Similar to the Japanese car owner, the Korean owner is anxious to prove that his Hyundai Sonata is a drop-in replacement for a Honda Accord, while secretly planning to buy an Accord next time. Let's take a moment of silence to remember those early Korean car buyers and their dreadful machines.

          American cars: Drivers are not paying attention. They didn't pay attention when they bought the car, why would you expect them to pay attention while driving it? Some will exceed the speed limit, but only in a straight line -- often beyond the limits of the brakes and suspension. The American car driver laughs about Korean cars, until he discovers that his own car is a lemon. Secretly planning to buy a Hyundai Sonata next time. American cars are the car of choice for people who like to complain about all the OTHER cars and drivers.
  • but call me stuck - I just can't get over the thought that the fabric can't keep the car as safe as metal does.


    I can see some of the benefits - you won't have to worry about dents and the such, but the isn't the possibility of having something tear right through the fabric pretty high (if you hit something on the highway the kinetic energy on it is rather high)?

      A lot of people are questioning the crash safety, but the metal skin of a car doesn't really have anything to do with that anyway. Stuff flying up on the road could be a problem, though it seems like that stuff always hits and chips the windshield.

      I think the most obvious danger would be someone taking a knife to the skin to break into the car and hotwire it. Or is this material stronger than that?

        Most cars (not trucks) these days are monocoque - they do not have a chassis. Therefor the strength of the vehicle is contained in the entire body as a whole from roof to doors to underbelly. About the only bits that don't matter are the wings over the wheels. Sure , theres extra crash protection built into the engine bay but thats in addition to the stregth of the rest of the vehicle. If you build a fabric car body you're back to using chassis' and the poor compromises they entail.

        All that does is save a thief from looking around for a brick.

        And, having slashed the bodywork apart, they'll still have to climb through/between the structural members of the car, which will remain metal.

        And, THEN, they'll have the chore of hotwiring a BMW, which is easily among the most nontrivial cars to do that with.[1]

        Honestly, I think brick-through-the-window is a faster method.

At specific points, the high-strength metal is enhanced by carbon struts with a higher flexibility. They are used predominantly for round, moving contours with a particularly narrow radius."

    So the chassis is still rigid right? Imagine unintentional impacts with external objects. The skin was meant to be protection for the car and driver. Flying rocks, small animals while the car is parked, pranksters, and thieves of engine parts make this not work so well. As well psychologically the driver will feel less protected in this new concept of a fabric skin. Imagine if your house was made out of cardboard... On the other hand I always like making cars lighter. I can see this becoming the norm if all the kinks are worked out.

    • Well, the reason it's easy to chip car paint is because it's hard. A flexible but durable surface might be a lot harder to damage from small, flying objects. As for safety, are you seriously asking if the car is only made from fabric, with no other structural protection?

      The car is parked in a driveway. A cat jumps onto the hood expecting a nice warm sunny place. Next thing it knows, the hood opens up, swallows the cat, the car emits a nice burp, and your gas tank increases by a few gallons. Sounds good to me :).

      Or what you do when it gets dirty? You take it off and put it washing machine with other your laundry?

      I have sprayed factor on my car. It cost 500 euros but it is needed to do only every fourth year. It takes one day to get done, you drive your car to workshop, they wash car, wax it and then sprays the factor on it. After that, it can take hit

    First off it's a concept vehicle. The point is to try new things, good or bad, to see how it works.

    Moving forward, the skin of this car is almost purely for aerodynamic effect. There is a certain amount of visual additive, and it keeps the wind and dirt off the occupants. In reference to other mechanical value, there are plenty of cars which have no skin at all and are faster than pretty much any other production road going vehicle. Ariel's Atom [arielmotor.co.uk], to name one. Cars don't need skins. Hell, look at motorcycles. The passengers aren't even contained in the vehicle!

    I think it's an awesome idea. Of course, my current roadster is paint chipped all to hell and being able to replace body panels of fabric would be rather appealing, but think about washing your car. Strip it down like bed sheets and throw the skin in the washing machine. Want a new paint job? Maybe a thousand dollars of fabric, or perhaps even just a dye job. You could change your car's color in a matter of minutes.

    That brings up a really interesting point. How do the police identify cars? Color and shape? Well those two are irrelevant with this vehicle. You can change the shape while you're moving and theoretically the color in about 10 minutes, I figure. It goes into a parking garage as a red roadster and comes out as a green pickup truck.

    Most importantly, and realistically, I'm sure the weight savings are impressive. And saving weight improves performance both in the go fast and the save fuel sense of the term. Imagine this combined with the Tesla Roadster. Shazam!

      I can't see how any fabric is going to have a lower coefficient of drag than clearcoat, so the only possible advantage with respect to drag is that you can do compound shapes more easily than you can with metal. The problem is this is BMW and it's going to be expensive no matter what so why not make it out of metal and gain the efficiency of ultra-smooth paint. I guess their engineers think they can gain more from lighter skin weight than is lost to friction?


      • It could be possible that the right type of fabric could reduce air friction. Although water and air turbulence is different, scientists have found that dolphin skin is faster underwater [iop.org] than smooth steel-hulled craft.

        Weight reduction is more valuable to fuel efficiency than reducing wind resistance. Both are important, but the biggest hit on fuel economy is generating momentum from a stop. Reducing weight reduces the energy required to put a car in motion. A BMW is going to spend more fuel going 0-30

    Which is exactly what that is, a concept, BMW comes up with an idea and floats it with the public to see what they think. Saturn did this with plastic bodies, "you'll never get a dinged door from a loose shopping cart.." While the metal skin of a car doesn't provide much protection, I bet it does add quite a bit to the weight of a car, and quite a bit of manufacturing (stamping, painting etc..) than a textile based covering.
