A6's and A8's have had electric "parking brakes" since 2005.

First off, the OEM's will have it termed a "parking brake", cars do not have 
n "emergency brake" any longer. Mercedes has used electric parking brakes 
or years. Mechanics have to be weary because they can/will automatically 
et after a given time so one must disconnect the battery for a brake pad 
eplacement. Scary stuff. The new Porsche 991 (2011 model year 911, 997 
uccessor) will have an electric parking brake too.

 on my latest business trip as arental - time for some testing :)

 First thing I noticed was that all seats had floor mats except for the
 driver's :)  Kind of funny.  Anyway, the first thing I wanted to test was 
 do
 the brakes win?  The answer was a resounding YES.  I could floor the car 
 at
 any speed or in any gear and apply the brakes with my left foot, and every
 time the brakes would bring the car to a halt.  So if people are actually
 pressing the brake pedal it simply cannot be a stuck accelerator for any
 reason, floor mat, sticky linkage or otherwise.  This leads me to two
 conclusions, asssuming not all 300+ complaintants are complete idiots.

 1. There has to be some sort of electronics/software that is not allowing
 the brakes to override the accelerator.
 2. What the hell is any car manufacturer doing with a braking system that
 could ever, given any failure, electronically override the pedal input?  I
 though antilocks were supposed to not do this.  There are some things that
 should be simple and bullet proof - brakes being one of them.  Of course
 recently I got a Cadillac rental that had an electronic emergency brake!
 Well I hope you don't need that if the car's electrical system has failed!
 Geez, what are these people thinking!
