Together the future is ours.
August Horch founded this company on one word: Progress. Back in 1909.
To us, it is taking what seems undoable and then doing it. It is discovering what no one else has bothered to discover.
It is turning skeptics into believers, and it is taking the thinking that wins on the racetrack and putting it on the road.
Relentlessly designing, innovating, engineering and racing for the past 100 years have yielded amazing progress in our
quest for the Truth. And although the Truth is absolute, it’s in a constant state of motion always revealing new limits
and opportunities. For instance, what seemed improbable has become the standard as we have created a diesel engine
so quiet, so clean, so ecient and so powerful we put it to the ultimate test competing in the 24 Hours of Le Mans…
winning three years in a row. But aside from walking away with trophies, we walked away with a deeper understanding
of what to engineer into our cars for the street. The remarkable capabilities of TDI

clean diesel power, the all-wheel drive
confidence of quattro

, and the increased power and eciency of FSI

are but a few of those strands of DNA that have
brought us that much closer to the Truth.
And it is that quest for the Truth that is behind every pencil line we draw, every calculation we make and every idea
we deem not good enough. And although they may prove to be remarkable achievements in their own right, they
represent a greater commitment to what is most important: Truth in Engineering.
