6sp Manual Takeoff From Hill
So today, I took off from a stop on a hill. To my surprise, the car didn't roll back. So on the next hill, I waited a little longer before rolling off the clutch and apply gas. Still didn't roll back. Shocked, on the next hill, I just let go of the brake and kept the clutch down. The car held its place for a whole second before the car started rolling back. Does our 1er have some computer controlled mechanism that prevents the car from rolling back from a stop? If it does, I had no idea it was able to do that. I'm assuming the 3 and 5ers are the same? When did this start? I didn't have this feature on my 04 X3. Wish I had this when I was living in SF, lol.

Hi, that would be hill assist. I have it on my '09 as well.

Basically it can tell you're on a hill, apply's the brakes and it gives you about 2-3 seconds to be able to let out the clutch and get on your way without the worry of rolling back. After the 2-3 seconds it'll disengage the brakes and will roll back. But you have to come to a complete stop for it to work. I'm not sure when it started but I'll just say 08 when the 1er came to the US. I'm sure they had it oversea's way before that though.
Its a nice feature and I'm so use to holding the e-brake/parking brake while going up a hill from a dead stop. |

I don't know how BMW does this but it is all programming. The car already has electronic controls for braking force for ABS and stability control. So the only added requirement is for logic. One way to design the logic would be to look for the car trying to go backward when it is in a forward gear and stop that. Judging just from how if feels, I don't think that is what BMW is doing. I think BMW is applying the brake after it is released possibly all the time but probably only when the angle of the vehicle says it is on a hill for a set period of time. That is pretty easy and helps. I think the vehicle angle sensors are also already there for stability control purposes.
I drive two manual transmissions regularly. I typically alternate daily. One is my bimmer with this feature and the other is a Suzuki SUV without hill hold. I like the extra margin of the hill hold but I've driven the SUV plenty enough to confidently start on a hill with somebody behind me. I rev the engine a little extra to avoid stalling but otherwise it is no big deal. Jim

Its a great feature but sometimes it can make you complacent especially in situations where it fails to detect you will rollback. Sometimes if the grade of the hill is just slight enough for you to rollback but not very steep overall it fails to engage and I start to rollback unexpectedly. Or if you happen to stop on a speed bump or with a wheel in a rut you'll roll back as soon as you get off the brake. If you're not used to the car rolling back because it never does on a hill this feeling can irk you or take you by surprise maybe a little more so than normal. When that happens its a rude reminder of one of the big differences of driving a stick that is usually covered up by our car's gadgetry There's also a way to fool it but I can't remember off the top of my head anymore. I think its something akin to if you're on a hill with clutch+brake in and you release the brake but change your mind and apply them again the hill assist doesn't work. When I figure it out again I'll post it here.
I wonder what this car would be like on a steep hill without this feature and given the fact that we have a CDV that delays clutch engagement? I'm sure it would be interesting. |

this feature threw me off when I was test driving a 135 for the first time...my current car I am selling has the same feature, but has to be activated by holding the brake all the way down, and I never used it...it just feels strange to me, but I am sure I will get used to it once I get my 1

Yes 08 1ers already have this. I like this feature when you're tired. But I miss the rawness of having the car roll back in the cars without this feature. really tests the quickness of your feet (or handbrake)

I'm surprised that anyone would "discover" this feature after driving this car for a while. Are there no hills in your area? Its obvious right away.
Plus I'm also surprised that people discover things about their car that are in the manual. I downloaded and read the manual to the car as part of my shopping research There are so many features on the car that aren't in the marketing brochure I was really surprised and intrigued. Every car I've owned I've read the manual back to front. I've even read the manual on my parents cars too. Don't you guys find this stuff titillating ? |

When I learned to drive my first manual transmission car 25 years ago, my father took me to a steep hill and had me come to a complete stop and pull away. We did this repeatedly until I could do this without rolling backward at all. (And no, I obviously don't ride or side step the clutch). I've never needed hill assist in any other car, I feel it's a crutch (like using the emergency brake) for inexperienced manual drivers. In fact my wife has used the e-brake in other cars when stopped on a steep hill. I always make fun of her. |

My 2010 WRX had it. After driving manual transmissions for years, I found the hill assist to be somewhat annoying. It would hold for a second, then roll back. Perhaps I was just not used to it and I did not have the car that long to get used to it.
