When I ordered my P90D in August, the specs said zero to 60 in 3.1 seconds. They day before it went into production all the changes were announced, including that the P90D now goes from 0-60 in 3.0 seconds. What do you think accounts for the difference? Much as I would like to ask the obvious question ("will I get the benefit of the faster car?"), I will refrain in anticipation of the probable responses (eg: "drive it and see....")
