The T-jet can easily give much more mileage, all else being equal, than the mere 10 you've assumed. Or so i have figured out in my five months of ownership of the new Linea. I currently get around 11+- kpl, in Delhi Gurgaon traffic, AC always on. Also, diesel prices will continue to increase by 50 p a month, whereas petrol ones may stay around 70. Now imagine the same cost calculation only with a bigger (1.5 mjd), more expensive diesel. The T-jet will then come out feeling like even greater value than it already is. But then, would that Linea with the much-demanded 1.6 mjd sell? Or get stigmatised as over-priced? But yeah: the mjd Linea makes for a superb value proposition, if one's running is high enough (say at least 1200 km per m).
