'A leaked BMW product planning document for the U.S. market reveals that BMW
will fit all 2011 M3s with an automatic start-stop feature to cut fuel
consumption starting with September 2010 production. If you're horrified by
the prospect of your M3 shutting down at traffic lights, take heart that you
can disable the feature.'
不如再搞个歇缸吧。。。 |

而且starter功率提高的话一下就crank起来了,甚至更经济
