Acceleration ? Noise? Were you on a road or track where you could drive fast? Was the test vehicle one of the black and white versions with the old style headlights? What can you tell us?
Acceleration was very smooth and constant through the highest speed that I drove it, which was 40 mph. The test area was laid out in a parking lot so the track was not that big. The acceleration will not set you back in the seat, but it is perfectly adequate for entering a freeway with a short ramp.
The road feel is the best that I personally have ever felt. The low center of gravity makes the vehicle very stable. Turning was effortless and precise. Braking was smooth, but I did not do any hard stops.
The test vehicle was not a black and white version. It was the one that traveled with the tour. It is shown in the following video:

This video is an excellent way of experiencing the noise. I do not remember hearing any noise except for the tire noise. No motor or wind noise during my test. And I also rode in the back seat on 2 other test drives. So I was in the vehicle a total of 4 trips around the track. I hate noise so much. It was a joy to be in a nearly silent car. Since this was a test car, it is impossible to judge how much noise insulation will be used in the production car.
