BMW M5 - Click above for a high-res image gallery

The next BMW M5 is due to arrive sometime in 2011 or 2012 and as the release date draws near, more details about BMW's newest 'Bahn-burner have begun to surface.

Two reports indicate that BMW may continue to use a V10 powerplant in the next M5, although there's still some evidence that the twin-turbocharged 4.4-liter V8 currently fitted to the X5M and X6M could be tweaked and fitted in its place. However, if BMW decides to stick with the bent-ten, a thoroughly revised version based off the 'utes' V8 would be employed, packing a duo of turbos to boost output up and over the 600 hp mark, and giving the Audi RS6 a run for its money.

But it won't be all about power. BMW is also expected to use an F1-style KERS system to increase performance and fuel economy, along with an engine start-stop setup and an eight-speed dual-clutch gearbox. If the rumors are to be believed, expect the next M5 to make its debut sometime in 2011, with sales beginning in early 2012.

      I'm enjoying the horsepower wars but soon CAFE requirements will make it next to impossible to continue making these kinds of cars. BMW can only sell so many Mini's to offset cars like these....

      I'd be more impressed if BMW got 600hp out of a 4.4L V8 than having to twin-turbocharge a 5.0L V10 to get that much like Audi did.

      Drive innovation BMW, don't be a sheep!
        • 5 Years Ago
        People get that much power from Civics too but there is so much more to a good engine than huge boost. That aside, the LS9 and the BMW V10 NA are both impressive, if in different ways.
        • 5 Years Ago
        either way you can't complian much about 600HP
        i'd say the .0L v10na is just fine and has enough power,
        but then who am i to get inthe way of HP wars
        • 5 Years Ago
        Coolio,

        The LS9 is a fine engine, but it sounds like you're bragging about lower cylinder count? With pistons the size of pineapples, that's not really all that difficult.

        Mercedes got more power and torque out of a 5.4L V-8... from the factory.
        • 5 Years Ago
        @timwang

        The LS9 is not in the CTS-V it's the LSA. They are different motors.

        "than having to twin-turbocharge a 5.0L V10 to get that much like Audi did."

        Agreed. This copying audi's intitivie needs to stop. yes the new m3 is fun, no it didn't need to just copy the displacement of the RS4 and power. no, the new M5 doesn't need to copy the RS6. As has been mentioned, make the M5 lighter, take a new novel approach, just tearing sheets out of quattro gmbh's playbook will only go so far.

        More awesomeness like the twin turbo 6 featured in the 135/335 plz.
        • 5 Years Ago
        Chevy can get more than that out of a super charged V8.
        • 5 Years Ago

        Zamafir gets it!

        If Audi had just gone back to the TT V-8, maybe they could sell the C6 RS6 in the US.

        But no, they build a V10 that can't even be sold in this country due in part to the emissions of the heavy TT V-10.


        Not exactly something to emulate for BMW.

        They already have the TT V-8 at BMW. They should stick to their guns and build it up.
      • 5 Years Ago
      Can't wait to see what the next CTS-V will be like with this to compete with (assuming it's still around).
        • 5 Years Ago
        lol @ GM trolls touting the CTS-V. BMW built a naturally aspirated V12 for the McLaren F1 that produced 627hp - and that was back in '98, so the engine in the new M5 is obviously gonna be a masterpiece.

        The CTS-V is supposedly a good car, but I really hate the "paper-cutout model" styling of cadillacs in general. Anyone else agree?
        • 5 Years Ago
        Good question. Since GM disbanded its performance division which means no more SS models (and if Pontiac was still around, GXP), does that mean the V line will die as well? Obviously the Corvette team is going to stick around... I wonder if they're just going to start dumping all the leftover performance operations onto them.
        • 5 Years Ago
        All GM has to do is put in the same higher revving titanium valvetrain that the LS9 uses, along with an appropriately tuned intake and exhaust, keep the same supercharger and they should get closer to 600 HP.

        And what is wrong with saying they can beat an '06 M5? Has BMW significantly changed the car since then? No, so it should also beat an '09 M5. Which is better than losing to it. And the McLaren F1 was a million dollar (USD) car which makes similar HP/L as the M5's V10; why hasn't BMW made progress there?
      • 5 Years Ago
      Two things:

      1) It does make me wonder what AMG would then have in store. With 518 hp, the E63 would almost certainly be overhauled in a couple of years like the E55 was from 03-06 with a new AMG-engined model. Autoblog reported almost a year ago about AMG having some new 5L TTV-8 with 575 hp/700 lb-ft. What every happened to that?

      2) I hope these stupid stop/start functions have defeat switches. It's one thing on an eco model, but I wouldn't buy a 600 hp M5 for its economy, fuel mileage standards or not. If that's what they need to meet company standards, build a uber-mileage 3-Series and 1-Series to try and make up the difference.
        • 5 Years Ago
        Why are you against start/stop system. It has nothing to do with the performance of the car. Or is it bad for your ego?
        I think is good for every car. Come on don't you hate wasting all that fuel while standing still?
        • 5 Years Ago
        I didn't understand it as them haulting outputs. Simply put, AMGs for most of their lives have been a sort of German muscle car. I love them, but the reports had AMG talking about weight and handling focus.

        Like I said, that to me meant that they would stop focusing on sheer power and concentrate on overall. A super-powered AMG E-Class still seems very possible to me, just not one that's got 625 hp and little else.
        • 5 Years Ago
        AMG did say the horsepower wars are over [for them], with their focus being making their cars more efficient. The idea of an efficient uber saloon is far more appealing to me than a thirsty one (rumour has it with minor mods a CTS-V can hit 28-30 mpg highway)

      http://www.g-power.de/820.html?&L=1

      GPower supercharges the existing V10 and puts out 730hp...With the R&D funding that BMW has, a twin turbo or supercharged M5 V10 will have 600hp EASY...

      The CTS-V is a monster and with VERY minor mods can be at 630hp as someone mentioned...Hennessey also has an 800hp tuning program...nuff said..

      Mercedes has formally stated that it will not keep fighting the HP Wars HOWEVER they also said they would keep up with competition by introducing lighter vehicle technologies...which makes sense...more HP usually means same or worse MPG, however lighter will increase power efficiency AND MPG efficiency...

      A Porsche 912 in the 1960's weighed 1000lbs less than the current Porsche 911/997...

      I need this in my life right now.
        • 5 Years Ago
        To bad it looks like my grandma's car
        I'll go with a CTS V anyday
        • 5 Years Ago
        CTS-V has them scared....
        • 5 Years Ago
        +1. When this car debuted it was unlike anything else, if memory serves, but subsequent models haven't looked as unique (enter cts-v, etc...). a TWIN TURBO V10 brings the crazy back, imo.
        • 5 Years Ago
        it'll be awesome... too bad it'll be a 5000lbs car by then.
      • 5 Years Ago
      All that for about, what do you think, $120k?
      • 5 Years Ago
      Yay!
      • 5 Years Ago
      I would be been much happier if it said they hired some Lotus talent and they were dropping 600lbs...

      I'd rather then go with a V8, less weight, the ability to have the engine further back in the engine bay, less fuel consumed. It sounds like a win win to me.
        • 5 Years Ago
        @Carlos
        @Timwang, my Viper with a Billy Boat exhaust sounds great, actually, never heard a crappy sounding V10 viper. Most of the time you can recognize a V10 by sound alone. Maybe I misunderstood you:

        "And don't even start with sound. "
        • 5 Years Ago
        @Carlos
        I honestly adore the M5's sound. A V10 simply sounds so distinctive: its much more angrier than a V8 and throatier than a V12.

        Oh, and no matter how good a boosted V8 is, it'll never sound as good as this V10. This engine is simply epic.
      • 5 Years Ago
      I'm guessing by the time the next M5 hits the streets, the CTS-V will get a power bump also, maybe in the form of an LS9.
      • 5 Years Ago
      interesting that it has Start/Stop. Can't wait til every car has some form of this tech tho, without using a giant battery however
