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 (*)
City10.72213.217.8
Hwy7.531.48.328.3
Combined9.325.310.123.3
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 http://www.bmw.ca 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.
