So interesting question on the money shift topic.....If you are in Efficient or Spot plus, notice how the car rev matches just before you are downshifting into the intended gear. Happens pretty fast. Am wondering if you were to accidentally money shift from say 3rd or 5th to 2nd, would the car over rev even before you go into second and let the clutch out because that's what you are trying to do (auto rev feature enabled)....go into second. Or it would protect against that and you would really have to be in 2nd and let go off the clutch to over rev and cause the money shift.

Hope that made sense.

Am guessing it will not over rev because there is no momentum involved from the wheels.

I am pretty sure the over-rev protection overides the rev-match function. The German engineers are usually smart enough to figure that out .

The engine can only over-rev by being mechanically driven by the wheels upon release of the clutch.

My understanding is that the rev-match function is indescriminate of up or down shifting. However, on an upshift, the revs are too high for th next gear, so there is no need for a "blip" to match the revs. The ECU will however hold the revs if one is too slow to complete the shift and release the clutch.

Wow, two things from this post and responses I've taken away... never knew what a money shift was and I've been driving one for more than 20 yrs and two most importantly never hope to attempt one, by accident or otherwise!

OP, I sincerely hope you get some kind of satisfaction here, Vet or not.
Good luck.

There is a correct way to hold the shifter, please do it. Don't grab the shifter like a gun handle in every gear. The F8x gearbox is so direct and so clean and crisp, use it to your advantage. Sit in your car and feel how each gear should engage - it is impossible to go 3rd to 4th and accidentally into second if you are going STRAIGHT DOWN and holding the shifter correctly. you need to physically pull the lever towards you in neutral and then go down into 2nd..

1st - 2nd = Grab the shifter like a pistol and pull towards you
2nd - 3rd - open palm and turn your palm slightly clockwise and push up and away
3rd - 4th - Put palm on top of shifter and flick the shifter down with your fingers directly into 4th (pistol gripping causes the inclination to pull towards 2nd especially when you are at redline, trying to execute the fastest speed racer shift)
4th - 5th - turn palm slightly clockwise like going 2nd-3rd, and push up up and away
5th-6th - palm opened towards 6th gear gate, push down and away

My method.. get used to changing your hand position and you will reduce your risk/chance of misshifting. Continue grabbing the shifter like a pistol in every gear other than 1st to 2nd and it is only a matter of time. This might seem like basic knowledge to some but for the people that grab it like a pistol, I highly suggest you consider why I always advise against it. But to each his own..

This is perfectly described!!
