I rented an Audi A1 – not an A3, but A1 wasn’t an option in the autofill form above – recently and both I and my passengers were shocked that the whole structure of the car begins to vibrate and feel wobbly at 55mph+ once the window is all the way. I was driving calmly, not particularly fast, nor was it a windy day. In order to try and see what was going on, I ran the window up and down repeatedly, and every time as soon as it was 75%+ open the car’s frame became buffeted and shook violently. It was smooth sailing with the windows closed.
Germans are famously meticulous and methodical engineers. I can’t believe they’d let a design flaw so large as this slip by. Furthering my confusion is the fact that Googling ‘Audi A1 window open shaking’ yields no relevant results. The logical conclusion is that this particular car I was driving was somehow faulty. But it only had 2,000 miles on it and passed both my and the company’s visual inspection, and I would have thought that any changes in the body large enough to so drastically alter the aerodynamics would have to be very obvious. Honestly I have no idea what to think at this point. Are all A1s designed such that you can’t open the driver’s window at moderate speed? Surely my 1991 Honda back at home wasn’t better-designed? This pos costs 15 or 20 times more. I can’t believe it.
