2015 BMW M3Images of the overhauled BMW M3 sedan and M4 coupe have leaked ahead of a debut at next month's Detroit Auto Show, along with option sheets and some specs.

Both wear the standard hallmarks of BMW's M division. There's a subtle power dome in the hood, along with the requisite M3/4-branded strakes on the front fenders. The front and rear fascia are more aggressive than what we've seen in the 3/4 Series M Sport package, as well. Split-five-spoke wheels mean the neither car will stand out in the family portrait and those gold calipers, meanwhile, signify what has been rumored for some time - the M3 and M4 will be getting carbon-ceramic brakes.

The cabin is home to the standard suite of M accoutrements, including a new steering wheel and more heavily bolstered seats. Special trim, including carbon fiber, will be available to further set these cars apart from the standard models.

We reported on the M3 and M4's powertrains back in September, but as a quick refresher, both cars will use a 430-horsepower, twin-turbocharged six-cylinder with the owner's choice of a six-speed manual or a dual-clutch transmission.

According to the options sheet provided by BimmerBoost, an adaptive suspension, 19-inch wheels and a head-up display will be available as optional goodies, along with a range of more traditional luxury options like heated and powered seats, a parking assistant, side and top-view cameras and LED lighting.

Finally, the color palette - both cars will be available in eight colors. The M3 you see above is in Yas Marina Blue Metallic, while we're guessing the M4 is Austin Yellow Metallic (which reminds more than one Autoblog editor of the E46's Phoenix Gold).

Take a look up top for M4 images and down below for M3 images, and then let us know what you think of the new sports cars down in Comments.

      I cannot wait for the commingle "BATTLE ROYAL" between the M3, ATS-V, C-AMG, IS-F.

      Predictable. If you like the current 3/4 series then there no reason not to like this. The difficulty BMW has with the M is, with current design of the base model, you have to almost go into desperate, tuner mode to design the M version to look distinctive. They have to justify more than double the price by making it look MUCH more aggressive.

      Dang, twin turbo I6. Hopefully forged internals. I might have to trade in my camaro for this.

      Alright now where are the leaked ats-v and ats-v coupe pictures at. The 3 series has certainly reach a plateau in design, which has left me uninterested. The 4 series is essentially a rehash of the uninspiring 3 series which makes no sense to me either. I wonder what Cadillac has in store. I surely hope its better than these offerings from BMW.

      Unlike most people, I'll withhold my judgement until I drive one and see some tests on it. However, I will say this: my opinion of it will weigh heavily on how two things and two things only: -How much it ends up weighing, and; -Whether or not they fixed the steering. And no, my expectations are reasonable. I'm not one of these guys demanding that the new M3 weigh as much as an E30 even though it has more than double the horsepower, five times the refinement, and ten times the luxury. It can't be done. However, if BMW can bring this car in U.S.-spec to our shores weighing less than 3,500 lbs. wet and well equipped, I'll consider that a victory. In other words, I'd be very impressed if they shaved 200 lbs off the car while making it structurally stiffer. Same goes with the steering: if they can make the tiller feel like the E46's or even the E90's, I'll be happy. If, however, this thing comes over weighing the same as the last one, with worse steering (resembling the F30's, for example), then consider me out and my faith in BMW lost. I can take a soulless and robotic M5. I can deal with the endless model-creep and confusingly long model names (Z4 sDrive 35is?!!! What the f--- is that?). Although painful, I can take the 4 series nomenclature, the softening of the regular 3 series, and the dilution of the M brand (M performance? M6? I think I'm going to be sick...). However, for me, this new M3/4 is BMWs last chance to show me they still know what they're doing. If they fail the M3/4, then to me, all hope is lost.

        I believe the rumored weight is 3300lbs, but people weren't sure if that's the curb weight or what.

        I dont know how they could fix the steering to your satisfaction. They are sure not going to turn back the clock and go back to a hydraulic steering. It is EPS from here on out.

      Dang. Nailed it. I didn't want to like it. But this is kind of epic! Nicely done. :)

      I think BMW took some origami lessons from Lexus for the lower fascias. Not good.

      AT least they didn't use the crap ricer vent that's on the normal 3/4 series cars... And I still hate how the headlights merge into the grille.. worst design choice ever regarding the headlights. And not a fan of the double pronged grille vents either, but at least that will be changeable in the aftermarket I am sure. Other then that a decent looking M3 but probably the bottom of the list compared to past M3's IMO.

        "crap ricer vent" '10s calling kurohouou ... rice rockets died in the '90s. Now we are talking Reich Rockets.

      LOL at everyone blasting this thing. It looks like a well-balanced, finely tuned, extremely fun-to-drive machine. It looks great and it will sell like hotcakes. BMW has made another winner and everyone will see this in about a year's time. Remember how you all hated the C7?
