BMW has outlined the changes to its model line that will commence during the production changeover in September. One of the most noteworthy among them is that every BMW M3 made will come standard with the company's Automatic/Start Stop feature. It will also come standard with an on/off switch, so you can leave your car running at stop lights should you choose.

Other M3 tweaks include the M Button on steering wheel, which will come standard with the ability to program your preferred driving modes, lighter Manual M Sport Seats, a Mineral White Metallic paint option, a Bi-color Novillo leather trim and a Convenience Package that replaces the Technology Package.

      Official specified fuel consumption for an Otto cycle engine, at idle, under no load is 0.6L of fuel, per liter of engine displacement, per hour.

      (source: http://oee.nrcan.gc.ca/transportation/idling/calculations.cfm?attr=8#footnotes)

      So, 4.0L V8 in the M3...
      0.6L of fuel * 4.0L of displacement * 1.0 hours = 2.4L of consumption while going nowhere, per hour. Consider an average commute, and this system could easily save 3L of fuel a day. Not bad...

      I trust the start/stop thing for the most part - all of the various hybrids I drive at work do it (Prius, Insight, Highlander Hybrid), and its flawless in all of them.

      Now, I feel even better about my 2011 m3 silverstone.

      Every car built today should have start-stop. It's inane that in 2010 most cars are still idling, getting *no* miles to the gallon every time they stop. Cars without start-stop are like a laptop that's always ON even when it could be in 'sleep' mode or your toaster always glowing red, just in case. Good for BMW. More please.

      Jesus Christ! Half of you sound like you still believe cameras steal your soul. This is proven tech. Do you honestly think BMW would voluntarily put something on the M3 that would have a noticeable effect on performance or reliability? Calm down kids, you'll all be able to hit the imaginary OFF button in your imaginary M3 and leave your imaginary engine idling at imaginary red lights.

        Your comment made my day! Seriously, one of the best I've read on autoblog.
        • 4 Years Ago
        BAM! right there^^^

      I think its a good idea, and those people who say that stop-start is pointless in performance cars should keep they mouth shut because they have no real fact for a proper argument.

      Strange car to introduce it on, dontcha think?

      This works best with DI motors, so it's funny that they're doing it on a non-DI motor. Hopefully it will work well.

      Would be nice to see this trickle down to the MINI and 1/3 series..

        fairly well. it works in temperatures over 3 Celsius when you move gear lever to neutral and lift the clutch pedal. engine restarts when you depress the clutch again to pull off or battery level drops too low. i have the diesel so at restart there is a bit of a shudder but nothing too disturbing. you cant really feel the engine shut down. the air con is electric so it works even with the engine shut(brake and steering assists aren't though so the engine restarts automatically if the car is rolling faster than 15km/h, of course the shut down happens at stand still and the car won't let you manually shut the engine if the car is moving faster than crawl speed). the air con uses a lot of power so at hot weathers the engine restarts after ~45 seconds to preserve battery charge. it is great when standing in lights as the restart is quick enough that you won't fall behind cars pulling from the lights in front of you. in stop and go traffic one must remember not to lift the clutch pedal all the way up(just a few mm will do) as the stops are too short for the system to offer any benefits. there is a disable button but the system reactivates at every key reinsert. also there is a minimum threshold speed for the system to activate(~10km/h) that has to be exceeded so that the engine won't shut down when maneuvering the car into garage etc. all in all quite well thought out system. bigger battery and faster start ups would be welcome but it is not a bother as is. for me the fuel savings are quite modest as it is cold for half of the year(i live in finland) and most of my driving kilometers are highway but for someone driving in the city mostly this might save a few € i would imagine.

        Ah, are you European?

        If so, how does the system work?
        • 4 Years Ago
        all bmw's with 4 cylinder engine and manual gear box have had start/stop since late 2007.
      • 4 Years Ago
      Does anyone know if there are published results for how well (or not well) the start/stop improves gas mileage? I'd really be interested to see if it makes any measurable difference.
        • 4 Years Ago
        Thanks man. I looked into it. Up to eight percent reduction in CO2 and fuel consumption. That's not too bad. I honestly wouldn't have expected that much.
      • 4 Years Ago
      I'd rather pay the small amount extra in gas and not pay for the wear and tear on the engine, starter, battery, my sanity etc. etc.
      Clarkson et al didnt seem to like it too much on the panamera either.
        • 4 Years Ago
        I guess that's why it comes with the on/off switch.
        • 4 Years Ago
        On Mazda's stop/start setup, the computer aligns the crankshaft in an ideal position before it turns off, minimizing wear and tear on all components and making for a very smooth restard. But this is on a direct injection motor. Which is apparently advantageous.

        It's very possible that BMW figured out a way to do the same thing.

        This could save quite a bit of gas... especially on this motor!

      It's not an f'ing Prius.
