On the economic front, the 35 diesel will definitely save money vs the 50 gasoline, both on the initial purchase price and on the fuel costs, but it's true that it's at best a wash vs the 35 gas over the three or four years you might have the car. (But, note to Coconut780, diesel engines usually need less maintenance and have a longer life than gasoline ones.)
One other non-economic reason for going with the diesel: it has lower emissions than the gasoline, which is a good thing if you care about global warming  |
+1...well put.
except for one little note on fuel comparison between 35i vs 35d...
I never fuel anything lower than 91 Premium on my x328i nor my previous X3...
So just for the sake of calculations, this is what we get comparing fuel costs and consumption between 35i & 35d...Assumption I've made: looking at the published fuel consumption of 35i & 35d on BMW Canada website...although they may not be the actual figures, but they should both apply as being relative. So here is the cost of fuel (per Liter in Canada), cost to fill up a 85 liter tank of X5, delta and the rest of the story:
Gasoline 91; Diesel; Delta per tank
Tank $1.43 per L; $1.36 per L
85L $121.55; $115.60; $5.95
9.6 litres/100 km; 7.6 litres/100 km; Delta mileage Delta cost
Mileage per tank; 885.42KM; 1118.42KM; 233.00 KM; $31.29
So, to get the same mileage on a 35i as on a 35d, you would need an additional $31.29 to give you that extra 233km plus the initial $5.95 which is approx. $38...
Does this make sense?
I think this alone justifies the $20 extra our friend was concerned about....
