If that is the reason for the different CO2 figure...
Perhaps VW are being a little more honest, after all, it's somewhat surprising that many CO2 figure are just below the VED boundaries - makes a huge difference in company car tax rates, and, therefore, sales. What do or continental members get told? Are their emissions just under their equivalent bands, or is it just the UK VED system that gets played?
That said, the is a clear information and advertising issue if the band is not as described. What difference could this make to buyers from April?
Seats - Most registrations are based on the design of the base vehicle/type approval, not the options, hence the 7/5 seat classification, and no doubt other folk, who retro fit a fifth seat, are glad of the extra capacity on the V5 as re-registration is a right kerfuffle.
