Audi A4 B7 RS4: motor tax, specs and NCT
Motor tax on a Audi A4 B7 RS4 in Ireland is €1,809–€2,400 a year, depending on the year it was first registered. Cars registered before July 2008 are taxed on engine size and later ones on CO2, so the same car can cost very different amounts depending on its registration date.
