I think that is in your uk galons and uk miles, and probably with the weakest engine. US MK7 is probably around 25-40mpg (US)
Yes UK MPG, miles are the same but the gallon we use is about 17% larger
Not the weakest engine by a long shot, it's the 2.0 TDI, 150 BHP with Bluemotion technology, my boss has the MK6, very effecient indeed.
Diesel is here in Houston 50% more expensive, so at the moment it does not make sense
Thats a big difference. If you got 30 MPG in your gas passat, you'd have to get 45 MPG in the diesel to have the same fuel costs, which I guess is acheivable, but not worth the extra premium to buy initialy.
