Today I recorded my best ever fuel mileage - 30MPG. 150 miles were in the city and 300 on a highway with a speed of around 80MPH (lots of police today). When I finally decided to fill up I had 451 miles on the odo with OBC still showing some 27 miles left.
It just shows how much of a difference highway driving makes on fuel economy. In the city my average is only 18MPG.

I wonder what your best and worst mileage is?

Best on the 325e was 30mpg. Best on the Miata was 35mpg. Worst on the 325e was 28, worst on the Miata was 19.

Usual commuting is ~29mpg for each.

Speed is the killer for me. I can drive it hard if I go high revs (4000-6800), lots of twisties, moderate speed (below 80); I can get 30-32mpg if I do that all day (learned that on fun drives). When I did 100+ all day (coming back up 101 from California to Oregon), I got the 19.

The e is just pretty consistent.

Yeah, I noticed that fuel mileage drops once you go past 80MPH quite rapidly. According to OBC my average going 80 is 33MPG, at 90 it drops to something like 26-27MPG.

at least for a good part :)

I don't know exact numbers. My average is about 23.6, my best is probably around 28

What do you tend to get 'round town? Those Minis are tempting on a couple of levels...

can't remember exactly...I think for the life of the car the OBC says 31.3 (I think the OBC # is usually a bit optimistic)

will double check later.

My best mileage was about 28mpg....
my worst mileage was about 11.8 on the track.... :eeps:

That's actually very good for a Steptronic.

I average about 22MPG. Combined city and highway, but mostly city. Pure highway driving, I went as high as 30MPG. Pure city driving as low as 17MPG. Remember, I have a S/C.

Track days 10MPG. ;)

How does one access the lifetime info?

How does one access the lifetime info?

through the NAV (keeps track of 'consumption 1' and 'consumption 2')

Yes, I haven't changed my consumption 2 since I picked up the car the 2nd time. I only regret not keeping track of my mpg while I had it for 2 weeks in Europe. It was probably pretty good considering it was during the break in period and I did a lot of autobahn driving.

So far my best is approx 26mpg (75% highway) and worse is 16.7 (city).

Watching the mpg gauge :rolleyes: the fuel mileage drops below minimum, which I think is 12mpg, while accelerating ... even if I take it real easy. I guess that is normal? :dunno:

I am doing about 21 in the city, but understand that is not pure stop and go traffic. Just typical urban stuff ranging from freeway speed down to neighborhood 25 mph zones. And believe me, I am no lightweight on the pedal and I hit the turns and pass people on 2-laners all the time. 28 is the best I have done on the highway, but I don't get much opportunity to cruise on a flat, straight road, so I don't think I have realized the max potential I might see out of this car in terms of mileage and I can't say I am exactly looking forward to it, either. :p

(i'd convert but i'm lazy... besides: see the 'metric' thread :p

my car: 15.1 L/100km (no highway yet, so pretty constant)
honda hybrid: 4.3 L/100km

:yikes:

the way gas has been lately, i'm thinking of buying one... :dunno:

Best (highway), 318i Valvetronic: 540 miles with ~30 miles left in the tank. That would be just under 42 mpg (Imp) or 35 mpg (US). This was all at 75-85 mph on European motorways. At 90-100 mph, fuel economy drops by 5-6 mpg. Aircon running full blast (~85 deg F outside).

Worst (all urban): ~300 miles with about 60 miles to go. 25 mpg (Imp), 21 mpg (US).

Old car (318is): best, 43 mpg (even better), wintertime. Worst, 19 mpg (even worse) springtime.

Worst (urban) : 30 mpg

I expect my gas tank to last the life of the car.

25-34 mpg. I drive easy now since the car is just a month old.

Life of the car (21,000 mi) is 20.2 mpg.

Does that mean I'm eligible to get my $1,300 gas guzzler tax refunded? :irate:

31.3 it is!

When I drove the 330 from Chicago to San Diego, I got 30.5 for the trip - two mountain ranges of hard driving and an average speed of about 78. What a car - power and economy! :thumbup: I had tanks as high as 31.5 on that car. The lowest was a full tank at 11.8 iirc - my brother and I shared the car at a hpds.

The /m seems to range from 18 to 22 with normal mixed driving. Depends on how many times I take the long way home over the small mountain. It doesn't ever seem to get more than 24, even on all highway trips. Speed is usually high though.

The week I got Karl Bimmer in December, 2002, I was getting about 20.

After nine months and 22,300+ miles:

Best: 26.5
Current: 25.7

Mine is very mixed driving; commute to work is 12 miles one way through Carbon Canyon. And then there are the trips from Chino Hills to Chino, Corona, Irvine, Santa Monica, Westchester, Pasadena, Anaheim, Pomona, Brea, Fullerton, Yorba Linda, etc, etc, etc...some is on side streets, some on highway.

I just finished a trip from the DFW area to San Francisco and back. Just out of curiosity I did a MPG check whilst cruising along at 100 MPH on cruise control and saw 21 MPG. At 70 MPH saw 28 MPG. My in-town average is usually about 17 MPG. I don't think that's too shabby for 333 HP. My general impressions of the trip were that: 1 The M3 is a great car on a long trip, despite the very firm ride. 2. 1050 miles and 14 hours in the car is WAY too long. 3. It takes a lot of concentration to drive the car safely at 100-110 MPH and is very tireing, but the car felt very solid and comfortable at those speeds. 4. Texas, New Mexico and Arizona hwys are fine, but California hwys and roads are in bad shape. Perhaps Arnold can fix that.
My lowest price for 93 octane was $1.75 a gallon in the DFW area and $3.00 a gallon for 91 in Needles Ca. on the way back. And oh yeah - I showed 24 MPG average for the whole trip.
