Just been reading about the new rates for vehicles registered after 1st April 2017 (announced in the budget 2015) which I assume will apply to motorhomes as well as cars. Some of the new rates look horrendous for vehicles over £40000 as even new Euro6 130bhp Boxers and the like push out 154 gm/ km which puts them in the 3rd duty band and for many will be on £40000+ vehicles which incur a further surcharge above the standard rate for 5 years. Am I correct it would be £500 first year and then £140 per year with a £310 surcharge each year for 5 years. I realise it is only for new vehicles and NOT existing vehicles. Have I got it right or have I misinterpreted the figures?
