• The 2015 F80/F82 M3 and M4 are not as light as we were led to believe - Curb weight will be in the 3400 pound range

      BMW is doing a great job hyping up the new M3 and M4 and they got a lot of attention by posting a 3306 pound weight figure for the cars. That is definitely light and it undercuts the E46 M3 by over 100 pounds let alone the even heavier E9X generation. BMW said the new car is 80 kilograms lighter than the E9X which depending on options is around 3580 pounds. Subtracting 80 kilograms (176) pounds from that gives us 3404 pounds. So what is going on?

      Well, the BMW weight figures posted are dry weight not curb weight. That means BMW's figure for the weight of the car is with no fluids or fuel. Obviously the car can not be driven like that so when the vehicles actually are driven off the lot they will be over 3400 pounds. BMW did this on purpose to skew the weight figure for attention and to exaggerate their weight loss figures.

      BMW confirmed the weight for the M4 is the dry weight in the press release for the new 2014 M4 DTM car, "The BMW M4 Coupé itself is a prime example of intelligent, lightweight construction. The high-performance sports car weighs just 1,497 kilograms when empty – that is a whole 80 kilograms less than its predecessor."

      So, expect E46 M3 levels of weight for the car and not the 3300 pound range we were misled into believing. Yes, still lighter than the E9X. Just not by ~300 pounds.

        Hasn't BMW always shown dry weight. So wouldn't the e46 numbers be dry weight as well?

        The problem comes in the press releases. The reviewers and columnists see them in the European releases well in Europe they release the weight figures as dry weight. We don't expect to see dry weight. The same thing happened With the 370z.

        I wonder if the DCT in the F30 is lighter then the outgoing DCT trans. I read the manual gearbox is 26lbs lighter…How they pulled that off or if it was true, I have no idea.

        I seriously doubt it's lighter. It may even be the same box.

        Seems like BMW still seems to list DIN at 1497kg (3300.32lbs), while EU is listed at 1572kg (3465.667) (90% fluids, 68kg (149.91lbs) person, 7kg (15.43lbs) luggage(?))

        But then in ( ) it lists the 7DCT transmission with DIN = 1537kg (3388.505lbs) and EU = 1612kb
        (3553.85lbs)

        Looks like they are estimating the 7DCT to weigh 40kg (88.18lbs) more than the standard manual.

        Can anyone translate german? I can't wait until we see "real" figures from a magazine that weighs the entire car with options, seems like BMW figures are over the board.

        They cite them in a way designed to portray them in the best possible light. They'll even twist them like BMW did in linking the M4 street car and DTM car which is just absolutely idiotic. I mean it's so stupid I can't even believe they did it.

        DCT car is something like 55lbs heavier then the manual M4 I read on some spec sheet... but don't ask me to find where I read it..

        But seriously, we should all wait and drive the thing and add some ingenious devices that I am sure Terry@bms etc will add and I am sure we will get some sort of joy from this new M version

        I have seen many analysis on speeds/times/traps etc suggesting a stock M4 with DCT going

        0 to 60 mph = 3.8-3.9s
        60 to 130 mph = 10-10.3s
        1/4 mile @ 119-122 mph in 11.9-12.2s

        Not bad for starters on a car that should be a 7.50ish on the Nurburgring so it will be quick around curves

        BMW isn't the only one who does this. Even the "curb weight" is usually optimistic. I want to say Road & Track (though maybe it's C&D) weighs almost every car they test, and they publish the claimed curb weight and measured weight. Sometimes there's a big difference that's more than just a tank of gas worth.

        wow...pretty disappointing but I guess it makes sense now given the weight of the 435.

        In their technical specification, the last E90 M3 weighed in at 1655 KG, the latest M4 weighs in at 1572 KG or 3466 lbs... 1655-1572=83 kilos = 182 lbs - not too shabby, but definitely not as light as expected.

        However isn't a 335i weighing in at with 3591 lbs of curb weight? I am using the same BMW technical document for each weight of each car. Am I missing something?

        have you all seen the latest weights?

        looks like the F8x is actually ~246lb heavier than the E9x apples to apples.. same options (so pretty basic, both with CF roof), half a tank of fuel each, real world measurement on scales.

        F8x on the scales

        i'd like to see a simlarly equipped E9x vs F8x on the scales (same scales)

        a stripper of each

        and fully loaded of each

        to compare the min/max weights and average.. real world.

        manufacturer specified kerb weights don't exactly mean much.
