First time you drive it, take it steady til it warms up, then drive it like you stole it. After that, every time you drive it, let it warm up then drive it like you stole it.
The engines have been bench tested prior to leaving the factory, they've been driven by all sorts of delivery drivers on and off before they arrived in this country, they've been driven by the staff at the dealers before you ever get your hands on it, and it'll already have had a serious taste of poor treatment from cold. Always warm it up, then anything goes after that.
