I found it. Seriously worrying about wind speed is pointless.
During one of the tests, the test driver ventured out to assess the strength of the fabric roof and all the support that is holding it in place. I AM NOT JOKING. The roof opened, although, it was actually very close to getting ripped off.
............ I mean, I haven’t heard about a fabric roof opening at 110 mph ever before. Let alone about the roof surviving such an incredible feat.
My point was that if BMW allow you to open the roof at 31mph then I guarantee you they tested it and engineered it to be able to open at double that speed.
