2009 BMW 750i: Road Trip MPG, Plus Albuquerque Travel Tips!
April 04, 2009
I've already written in detail about my road trip in our long-term 2009 BMW 750i, bragging about its long cruising range and excellent headlights . Now I've got the fuel economy results for you. Although my numbers are short of the 750i's 22-mpg EPA highway rating, I'm still impressed given that (a) this car weighs 4,600 pounds; and (b) I didn't drive 75 mph.
Total miles: 1,948
Total gallons of 91 octane: 95.406
Average miles per gallon: 20.4
Best tank: 21.6 mpg over 435.7 miles
Worst tank: 19.2 mpg over 375.8 miles
5th gear, 6th gear & final drive ratios: 0.867, 0.690, 3.462
My best tank comes with a slightly amusing story: I get an early start on the drive back to LA from Williams, AZ. With the distance-to-empty meter showing 59 miles, I decide I'm too cool to make a fuel stop in Seligman, AZ, only to see a sign immediately after the exit ramp that says, "Next Services 56 miles." I look back at the DTE meter and it's already fallen to 55 miles. Oops. I spend the next 56 miles kinda-sorta hypermiling, finally pulling into the next gas station with 8 miles to empty. I put in 20.133 gallons, so with a 21.7-gallon tank, there's still a small reserve.
During my 24 hours in New Mexico, I visited the Unser Racing Museum, a collection of cars all driven by members of the Unser family. The Unsers are from Albuquerque; there's even a road named after them. The photos below are just a sample; the museum has a whole room dedicated to the Pikes Peak Hill Climb and another to the history of race engine and tire technology. I also got a great restaurant recommendation from a museum docent: Sadie's, which makes traditional New Mexico food. Trust me, it's a mandatory stop in Albuquerque.
