Mein Auto: 2011 X5 35d
I actually did this calculation to determine which was better for fuel economy. Here are the numbers that I could calculate. If anyone sees any discrepancies, please let me know.

2011 X5 35d (1)2011 X5 35i (2)
L/100kmMPG (*)L/100kmMPG (*)
EPA Cost per year (3)$1,741.11$2,141.09
CDN Cost per year (4)$2,119.30$3,008.20
Distance per tank568 miles / 914 km523 miles / 842 km

Notes on numbers:
(*) The MPG numbers are converted from European L/100km to US MPG. I couldn't get the 35d numbers to match the 19/26 that the EPA suggests for the 2010 35d and since I couldn't find EPA numbers for 2011, I converted from L/100kms that could be found.

(1) From specifications at the website. In the Canadian 2011 X5 press release, the highway fuel economy was mentioned as the same as the 2010 so I am assuming the same numbers.

(2) From Specifications of the new BMW X5, 04/2010 which are European specs but are the the same as Canada.

(3) Based on EPA's Cost/Year formula of 45% Hwy/55% City for 15,000 miles per year where gas is $3.05 per gallon and diesel is $2.95 per gallon. DEF NOT included.

(4) For comparison, sort of based on EPA's Cost/Year formula of 45% Hwy/55% City for 15,000 miles per year where premium gas today is $1.132 per litre and diesel today is $0.949 per litre in Toronto, Ontario. DEF NOT included.
