2009 BMW M3: Video of the Variable Redline
September 23, 2009
We've posted about the M3's variable redline before. Start the car cold and the BMW's tach shows a lesser redline (How much less depends on temperature.) and then the redline adjusts as the car warms, eventually reaching the engine's true redline which is 8,300 rpm.
Thing is we've only shown you photos and this is the kind of thing that demands video. So I shot some. Yesterday morning. But I warn you now, it's very, very, very, very, very boring. It takes 8 minutes before the BMW says it's free to be revved to 8,300 rpm.
But don't fret. For those with ADHD I've posted a much faster version of the video on the next page. Enjoy.
