The only time I feel vibration from the N20 engine is when it starts.

My instructor at the BMW CCA HPDE this weekend commented that he could not tell when the engine was on, after we put on the helmets. With the helmets off, we could hear the engine, but vibration was almost unnoticeable.

The car performed far better than the driver, BTW, at the HDPE.
