At this distance of travel I know you should not or at any time.
Rev engine high until normal opperating, Temp as big ploom of blue smoke but dose not happen at normal temp but if rev hard black smoke is this carbon build up or turbo problems as this is new car well to me

U have a turbo going bad, check again when u first start car in the morning, u should see smoke again, also u need to get your o2s sensors check for proper function , black smoke is may be poor fuel to air mixture, meaning poor o2s sensor operation, but could also be other issues, start there. Good luck.
