BMW 3-series brakes in Popular Science Top 100 of 2005 |

The brakes on BMW's new 3-Series feature a host of life-saving tricks
packed for the first time into one vehicle. They anticipate an
emergency stop and cinch the pads closer to the rotors, so they engage
faster. And because they resist fading during long descents, you can
stop quickly at the bottom. They also squeeze the calipers
intermittently in the rain to keep the pads and rotors dry and, when
stopped on hills, hold the car while you move to the accelerator.
I have a question about the last line in the blurb... does it mean that
when you are on a hill and you car has a manual tran, that the car will
not roll back when you begin to go into 1st gear?

Subaru had this years back "Hill Holder Clutch". I would hope BMW has tied it
into the clutch, otherwise, if your engine dies, you'd not be able to move back
into a parking spot or back into your driveway, if the driveway is downhill....

Yes, the newer BMWs have this (automatics and manuals). It only does this
for a few seconds, then releases, so you can still roll back.

Why would you want or need this on an automatic? The engine idling
already holds the car from rolling back on most hills and, well, you do
have a spare foot down there doing nothing...

Not necessarily. On my (other famous German brand) car, model 2001, the car
rolls back on a hill despite the auto gearbox. Was very disconcerting at
first since my old 1993 model (from same famous brand) does not do this.
I am told this rollback is quite common now (and is not a fault).

the anti rollback feature does work for manual and auto trans.
and it only uses the brake pad not clutch, the point is to save the
stress on the clutch not ad to it.

I drive a manual E46 and I can hill-start so I don't care!
But I would say it would work on slopes which are even too steep for the
engine to hold on idle. Maybe.

The Hill Holder has been around for over 50 years, Studebaker had it
starting back in the early 50's.

In my 6-speed it only works if the clutch pedal is pressed down. So
rolling back can be easily done by letting off the brake while out of
gear - just don't push the clutch pedal.
