It’s said that when one door closes, another one opens. It

sounds as if whoever said it spent some time at an Audi re-

search and development facility. After all, while you’ll open

and close the door on your Audi thousands of times without

thinking about it, we’ve obsessed about it for you, in detail.

Not just about the reliability of it opening and closing,

obviously, but on the proper weight that will make it more

pleasing to close. What it should sound like when it is shut.

How the locks should click when they are engaged. The opti-

mal acoustic placement for the speaker port. There are the

hinges too, of course. And the door itself, which is designed

to take the brunt of side-collision impacts, along with sev-

eral dozen other considerations that we take into account

when designing our doors (to say nothing of the countless

other components, processors, sensors, features and the

inner workings most people will never see). Our doors are

more than a symbol of welcoming you into your vehicle, they

are products of Audi engineering, and our reputation hinges

on them as much as our hinges help support the door.

It’s Audi because

our reputation hinges on the quality

of things you don’t see.

1 Doors and Closures Innovation Award 2011, Automotive Circle International. The award is annually bestowed by Automotive Circle International

for the most innovative door or closure development in automobile series production.

Speaker placement and enclosure

We work with our partners to select optimal

placement of our speakers, a vital aspect of

our door design, in order to deliver the most

engaging and extraordinary sound you can

ﬁnd in the automotive space. Woofers use a

specialized lightweight and ported enclosure to

ensure optimum low-frequency reproduction.

Award-winning design

When Audi engineers set out to build the

perfect door, they had one very important

goal—lighten the load. By using fully pressed

aluminum doors, the weight of the Audi A6 door

structure was reduced by an astonishing 44 lb,

compared to the previous model. This feat,

combined with the strength of its door hinges

and ability to retain all of its mechanical,

safety and infotainment features, is why it

won the Doors and Closures Innovation Award.

Acoustic enhancements

We spend countless hours listening, so

you don’t have to. By using soft-mounts

on our window regulator, or a sound

absorber backing within the door cavity

itself, as well as a simple foam liner on

our door-release cable, Audi engineers

have nearly eliminated all of the ambient

noise associated with other less-than-

acute manufacturing practices.
