What Rpms do you guys shift at
Hi it's my second post here . I have completed my 2000km break in and have got the first service done . My question is that apart from hitting the red line couple of times what Rpms do you guys shift at . What should the shift points be considering I want to keep this car for a long time .
Thanks for your inputs. |

1st gear at 7800rpms (because the tachometer lags behind the revs)
Every other gear, ~8,400rpms

It's funny how on every car forum people ask this. As if there's some magical number that is correct.
Here's a short answer, it varies. Does that help? |

Ironically, depending on the engine, configuration, there are sweet spots for shifting and keeping ideal mpg. While it depends in general, you can find the ideal operating rpms and gears for highway and around town driving to achieve the particular desired results. My previous car was turbocharged, after a certain RPM, power would drop, before redline, so shifting points would be adjusted to power curve, not redline. |

depends on whether you're a "serious driver" or if you plan on breaking your rear differential bolt

If you're concerned about prolonging engine life then shift at 2.3k rpm's always. Last I heard however, when an engine is tested for any kind of durability, they (the auto manufacterer) runs it at or close to redline for something like 30 hours straight. I could be way off on this but I think it's somewhere in the ballpark.
You're engine will outlast you and whatever you choose to shift at so long as you are maintaining it properly. |

Over thinking it bro...
There are much more important things that will make this engine last longer than at which RPM you shift. This is an M3, it was meant to be beat on and driven hard. Shifting at different RPM will help you attain better fuel economy, but I don't see it having any correlation with engine life so long as the car is maintained well. Someone correct me if I am wrong. |
