I think Tim is spot on as it is the ability to pass safely and quickly which counts. I would like more of that and spoke with Henry at Williams about a bit more oomph. With gps mine hits the rev limiter (6500) at 72mph in second and 96mph in third and seems to do that quicker than my friends plus eight .However changing up at around 3500rpm seems to deliver a smooth band of power, enough to deal with the everyday conditions. If I could gain more power I would be happy but it seems quick enough and I am still learning to drive it after all these years.
