no they didn't change it in the budget.This is only for cars registered on or after 23/03/2006 so if your car registered before this date you will only pay £210 per year.
i have also included a link to the government website showing how much people will have to pay each year.
as the zs 180 are 227g/km exhaust emissions they will fall into the over 185g/km category they will not fall into the 225g/km as this is only for cars registered on or after 23/03/2006.
here is the link so everybody can see it for themselves.

you need to look at the second box down for petrol car (tc48) and diesel car (tc49)
and the zs 180's fall into band f not band g as it says for vehicles registered on or after 23/03/2006
