2003 330i zhp 6-speed Suburbanish-city driving: 19 mpg Highway 65 mph on cruise: 34-35 mpg Both on premium; regular does not seem to make much difference. The city number is a little disappointing as my wife's RX330 does 17-18 mpg and it is a big lump. Sure hope they start doing hybrids or importing manual shift diesels.
#74 of 74 '07 328i: Impossible highway numbers? by dmaccioc Nov 16, 2008 (8:48 am)
I have an '07 328i, auto, non-Sport. I live in the SF Bay Area and usually sit in a bunch of traffic, so I normally only average about 21-22mpg. When my parents were visiting in September, they took my car down toward LA for an overnight stay. They got 36.8mpg on the way down!!! I did the math, and it's true. My dad said they filled up, got directly on the highway, set cruise at 70, and didn't hit any traffic. On the way back, they got 32mpg - I think partially because my mom drove for an hour and she didn't use cruise control. Last week I had to go up to Sacramento for work (105 miles each way) and averaged 33mpg, setting cruise at 75 at some points. Very happy with the fuel economy! Is there any particular reason why my car gets such good numbers?
