• AutoBild claims to have the 2014 BMW F82 M4 specifications - Lightweight emphasis, twin turbo S55 3.0 liter inline-6, 7800 rpm, 416 horsepower

      Things are getting interesting. So those reports of the BMW F82 M4 having 444 horsepower that had fanboys complaining? It is looking like it will have even less than that out of the gate with a claimed 416 horsepower. Please do not throw anything at your monitor. BMW is having fun charging twice for horsepower these days with "Performance" software swaps so it is basically a certainty that just like the M5/M6 the M3/M4 will have a Competition Package that should boost output above the 444 horse figure reported earlier with a claimed 35 horse gain from the package.


      Horsepower is one part of the equation and not the be all end all. What is interesting is that the redline is claimed to be 7800 rpm. That is pretty good and the highest redline of any BMW production turbocharged motor. It is not E46 M3 S54 8000 rpm good, or E92 M3 S65 V8 8400 rpm good, or E60 M5 8250 rpm good, but it's good and better than expected if true. Keep in mind spy shots of the tach captured by BimmerBoost members have shown a lower redline.

      The F10 M5 and F12/F13 M6 need their horsepower and torque to move their huge asses, especially the M5 which is a fat pig. An emphasis on lighter weight is exactly what BMW needs. Frankly, it's long overdue but clearly BMW is responding to the warranted criticism. It is difficult to claim to be Efficient and Dynamic when the cars outweigh the competition.

      If what AutoBild reports is true then the M4 will weigh 100 kilograms less than the standard 4-Series. That would mean a curb weight in the ~3300 pound range. It sounds almost too good to be true but with optional ceramic brakes and various lightweight body pieces they may hit that weight. That would make this the lightest M3 (shut up Bimmerboost knows they are calling it an M4) since the E36. Now that is something to be proud of. It also makes the F80 and F82 chassis designations versus the F30 for the 3-Series and the F32 for the 4-Series suddenly make sense if the construction materials differ greatly.

      Other options other than the ceramic brakes and competition package include a valved exhaust system and 20 inch wheels. Oh, and a 6-speed manual option of course. The 7-speed DCT will not be forced on you (as it should not be in a drivers car).

      This is much, much better than anticipated if accurate. It seems BMW is finally responding to the criticism of fat cars that no longer offer the best driving experience in their class. It is a certainty that the new W205 C63 AMG will outpower this car with its 4.0 liter twin turbo V8 but if the new M3 is significantly lighter it will not need as much power to compensate while at the same time running circles around the C63 AMG on the roadcourse.

      Limp mode issues will still be a concern with the turbo motor on the track and we will have to just wait and see how it holds up in a racetrack environment.

      BMW and M are certainly not back as that once special M shine and swagger will forever be diminished but this is at the very least (once again, providing it is accurate) a step back in the right direction after quite a long string of BMW and M disappointments. Let's all keep our fingers crossed.

        Agreed - 100%. I don't understand why they can't make a bad-ass m335is M-sport++ Lime Rock edition AND a NA bad-assM3. I would think they would sell MORE cars to be completely honest.

        For some reason I remember reading it was a Nissan sourced motor, I don't know enough about it though.

        The main reason I can think of is sharing motors, parts, and keeping costs lower for higher profit margins and being able to charge for performance software on the M models so making even more money.

        I completely agree with this. you have the badass factory boosted car for people like me that want to go fast in a straight line for cheap and the have the factory high revving N/A car for track people. with that being said, getting more HP out of an N/A motor (s65) while keeping 50/50 weight distrbution was going to be real difficult for BMW. Unless, they went straight GT3 with it, but then what does your average old person that only buys it because it's an M3 and will never track it, what does he buy?

        Agreed. I think they've lost touch with the enthusiast buyer and only care about profit/sales volume at this point.

        Why? Porsche gets 500 hp (underrated) out of a freaking 4.0 liter flat-6. BMW has up to 4.4 liters and even 4.6 liters to work with in the S65.

        The problem isn't power with the V8 it's the weight gain of the M models.

        You throw a 4.4 liter 9000 rpm 500 horsepower V8 in a 3200 pound M3 with DCT and what the hell more do you need? Now that's something actually worth almost $80k. Plus just imagine that motor with a supercharger. Kidding. Maybe.

        I agree. If the rumors about the 3300 lbs are true I would think the S65 would be more suitable for this chassis than it was for the e92.

        Less weight benefits everything. The V8 is more than powerful enough even as it sits.

        I think at best about 3,450 and that is with carbon ceramic brakes.

        (435i per BWMUSA) 3,610lbs - 220lbs = 3,390lbs + about 60lbs (normal US seats) = 3,450

        If you don't opt for the expensive carbon ceramics then add another 50-60lbs.

        So... 3,500+

        That's pretty heavy. Is that heavier than the e92 335? Also what weight is that? Is that with driver luggage and all of that crap. They way they way these cars is confusing.

        I wish they would offer the performance seats in the US. Why dont they...because we are too fat?

        Is it they just don't want to do the testing? Porsche offers nice seats as options. I don't know if they are similar to the bmw seats though.

        Porsche doesn't bring over their special carbon buckets either. It may have something to do with a side-impact airbag. Regardless, it's some stupid US regulation.

        Why are you taking BMWUSA weight spec for the 435 and then adding US seats back into the figure? Do you think the specs on the BMWUSA site for the 435 are using the super light seats that the M4 won't get in the US?

        Porsche used to offer carbon racing buckets for the 911 and the Cayman R/Boxster Spyder models (not sure about the 991 and 981). I don't know if these are the specific buckets you are referring to... Could be that Porsche uses a different setup for side impact protection that allows a racing seat to go in and still comply with the regs.

        The 100kg (220lbs) reduced weight from 435i stated in all articles includes carbon seats.

        So, lets take out the seat figure from the weight savings rumor.

        220lbs - about 60lbs (normal US seats) = 160lbs

        (435i per BWMUSA) 3,610lbs - 160lbs = 3,450

        Add another 50-60lbs if you don't opt for carbon ceramics...3,500+

        The ones I'm referring to were in the Carrera GT and GT2 I believe but regardless everyone has a problem with this seat regulation. It's stupid.
