Right how much u paying for a year tax on your every day car?

AS i know its about £90 for 6 months for the cossie! But just had tax reminder through for my Passat TDI and its £115 for a year or £65 for 6months Thought thats a bit cheap its like its in the 1400cc bracket So i presume its going of emissions? Anyone else with a modern Derv paying about the same for tax?
