TDi130 or V6TDI??

[neil_f]

Hi, I've had various VAG cars over the years (Ibiza tdi, Leon Cupra R , MK1 & MK3 Golf, Audi A4 tdi130 etc,) but looking to buy a B5.5 passat. Looking at tdi130 or the 150bhp V6 tdi. Is there a huge difference in economy between the two models? - mostly motorway driving 70-80mph (used to get about 50mpg from the A4) . Is the V6 diesel far more refined than the tdi130?? Does the V6 feel noticeably quicker?? Sorry about all the questions just fancy the v6 version but not if the economy is vastly lower. Cheers.
