From 1 April 2018 the first-year VED tax rate for new diesel cars will go up by one band. The standard rate after the first-year will remain the standard rate, currently £140.
Every new car will fall into a tax band dependant on its CO2 emissions and each band has a first-year rate which was overhauled last year, from 1st April 2017.
Now, from 1st April 2018, the government has introduced a new tier for diesel vehicles that do not meet the latest Euro 6 emissions standards. At present no new diesels conform to the RDE standards, so the extra fee will apply to all new diesels sold.
A diesel vehicle will cost more to tax in the first year than a petrol, however the difference for a vehicle in the lower bands is minimal in the overall cost of purchasing a new car. See below the difference in cost between petrol and diesel in the SEAT range:
SEAT Leon 1.0 litre
SEAT Ibiza 1.0 litre
SEAT Arona 1.0 litre
SEAT Ateca 1.4 litre
SEAT Alhambra 1.4 litre
SEAT Leon CUPRA 2.0 litre
