    Insideline tests the 2012 F13 M6 Convertible, 4,495 pound curb weight and 12.2@116 1/4 mile - Better than the previous gen?

    The new F12/F13 M6 is a beautiful design, no doubt about it. However, an M model is supposed to be about performance and engineering over style. This new M6 cabrio was supposed to be slightly lighter than the previous generation E64 based on the BMW press release stating a 4312 pound weight. Well, Insideline tested it at a staggering 4,495 pounds. This is 122 pounds heavier than what they tested the previous generation M6 convertible at which was not exactly a lightweight itself.

    This heft contributes to comments in the review stating the car feels too big to really be tossable (hurting the fun factor). The new Mercedes SL even with its folding hard top manages to be significantly lighter. It really is a shame these new M models are so bloated and that they keep putting on weight. What is this efficient dynamics crap BMW keeps talking about? The 6 Series convertible had to get a folding soft top just keep the weight from ballooning even further. New Porsche and Mercedes models manage to be lighter than the models they replace and offer more power while being more efficient. BMW somehow keeps gaining weight with the new cars and we are not talking about an insignificant amount.

    This weight hampers more than just the feel it also hampers the acceleration as the F13 M6 only manages a 12.2@116.6 in the 1/4 mile. Insideline hit 12.9@113.4 with the previous generation E64 M6. So the new model is quicker and faster as it should be but with a twin turbo V8 and a dual clutch transmission it only manages to gain 3 MPH of trap speed over the naturally aspirated V10. The improvement is minuscule. We would be willing to sacrifice the 3 miles per hour of trap speed to have a motor that sounds glorious with better response in a lighter car. It seems BMW really needs these twin turbo motors and all their torque just to move these new M cars. And yes, Insideline does complain about the poor motor sound of the S63 twin turbo V8 in the M6 as just about everyone does.

    The new car is faster, better looking, and does pull more g's on the skidpad. It is a great car. However, it feels like BMW has lost some of the magic that made them special. It is almost as if they are becoming what AMG used to be. Big and somewhat isolated heavy cars with a lot of torque. What made the E64 M6 unique in the marketplace does not apply to the F13 M6. It definitely looks great but BMW's strength was always more about what is underneath the skin. Now we are falling more in love with what is on surface. Superficial aspects can be fun but it is only so long before you start looking at what else is offered. It will sell and people who buy it will say they love it but they will never realize what the car could have been had BMW actually made an effort to apply their "Efficient Dynamics" to the chassis rather than sacrificing classic traits for a couple miles per gallon... oh well.

    That's a heavy car. 4500 lbs!? That's as much as a ford F250 with a fat baby in it. How is that thing supposed to handle well when it weighs as much as a veyron.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    This is ridiculous. I wouldn't mind it if the had a mid-engine car that weighted 3,000lbs but they dont. Its a shame that the M6 is the halo car for the M brand.

    That trap is low for the previous generation. I think I trapped 118 in my e60 m5 stock sans charcoal filters.

    One advantage to the M6 is the amount of space the car has. You can literally take 4 people to the beach and this is a huge selling point for buyers.

    However, looking at the new BMW's in general it's like they completely threw away their philosophies on lightness when they flushed N/A motors down the toilet. So turbo's mean we can get fat as well? Get it together BMW, the only things i'd buy that your producing are N20 or diesel powered

    It is low but I went by the same source to keep it uniform. The new car is faster but barely.

    A 4 seat cab is very appealing but does it have to weigh more than some SUV's in the lineup?

    I don't see how they can put an ///M badge on anything this big and heavy and still look themselves in the face. Clearly M now stands for Money instead of Motorsport. I suppose it always has in the case of the 5er and 6er since they really haven't raced these versions, but it's simply become obscene with this latest revision.

    They already showed they had no shame with the SUV's so this is nothing.

    I could write a book on this topic. I'm actually considering doing so.

    Amazing! This thing weights ALOT more than a Camaro vert or even a Challenger, by over 300lbs!!! and those are BIG cars!! Damn ///M going down the drain bad, just like all of BMW. I really hope the upcoming M3 doesn't dissapoint as much as all the latest BMW vehicles.

    I've sat in the back of one. That back seat is meant for someone under 5' 6" and with no legs.

    There is truth in this statement.
