I am getting numbers no where near 40. I get 29ish city and 35ish highway. My tank by tank numbers fluctuate in a narrow range in the low 30s. This fluctuation reflects the mix of local vs highway.

I do get extraordinary (40 or so) on the first half of a tank. I make this statement based on the OBC's projected miles remaining according to the fuel in the tank (plus, of course, the elapsed miles thus far.) However, those numbers never hold later in any given tank. I guess the tank has an odd shape for which the OBC does not adjust.

 

Automatic or manual? Ignore the OBC... the info it provides is too inaccurate to include in any real findings.

 

We have about 3,500 miles total on our clubman with an average mpg hand calculated at 37.5mpg in an Automatic Clubman Non-S. We are very happy with this number.

 

Yeah, the "guess gauge" is pretty non-linear. I put 10.6 gallons in it with it still showing right at half a tank, and the OBC projecting another 170+ miles.

 

Very good for an automatic! I'd be happy with that too.

 

Picked up the Clubby (manual, non-S) almost 3 weeks ago. It has about 1500miles on it now, and when I filled it up last weekend, it had gone 471 miles and took 13.0 gallons (36.2mpg) and it was our usual mixed driving - about 30% city, 70% highway. OBC claimed 37.5mpg, which is actually more accurate than I had expected. The wife is thrilled with the mileage; I am pretty happy also and expect it to gradually improve as the engine loosens up a bit more.

 

I got 24.9 mpg on my first tank. 333 miles. I am a little surprised it was that good.

I might slow down on this one and see if I can sniff 30mpg.

Clubman S manual

 

Is your first name Larry and is your right foot composed of lead? I'm sorry I could not resist. But seriously, I am waiting for my Clubman but have been experimenting with my Honda Accord. I AM a Lead Foot Larry and have been getting consistently 25 MPG (which I thought was great!) with the Honda. Then someone mentioned trying to milk more mileage by using their cruise control set on 65 and I said hmmm and tried it. Boom - 29 MPG. Of course my kids in the back seat complain about how SLOW daddy is going and why can't you go faster, in addition to every car passing me at light speed (I live in the Bay Area). But 29 MPG! I can't wait to try out the clubman when it arrives. Will contribute to this data gathering group as soon as I can (in about two month's time).

 

Only been driving Maggie Mae for a week, 450miles, but obc says 24.9mpg. Beats my '99 Astro's 16mpg.

 

Auto.

Regarding the OBC...so I've learned!

Will need to buy gas today. Drum roll, please.

 

Second tank: 38.6 calculated!

Happy man, I am.

Now, I've got a question I'd like to add to the equation: I notice that the S owners are (maybe more than) incrementally lower on fuel mileage. For the non-S owners, can someone comment on what their wheel/wheel size/tire setup is? I'm curious to see what folks with the factory 16" wheels (like S-winders and Bridgespokes) are getting.

 

Filled up for the first time today in my new Clubman S () Manual Transmission

Fuel in: 12.951 g
Octane: 93
Miles: TBD
Station: Kwik Fill, East Aurora, NY

(Kwik Fill is all North American Gas, and has no Ethanol to my understanding in it, which should result in better mileage for those of you in my area)

Fuel from Dealer (Assuming he topped it off, which is unlikely IMO) lasted 340 mi. Down to 2 "bars" on the gas gauge, pulled in with "47 miles" to go according to the OBC.


Assuming top off, gas calculations are as follows:

City (Suburbs/Around town) / Highway = 60 / 40
Fuel "used" : 12.951 g
Miles Traveled: 340
OBC MPG average: 29.0 mpg
Hand Calculated Average: 26.25 mpg

***First day I got it I didn't know how to drive stick, so this number includes about an hour of start/stall time in a parking lot ***

 

Frankly, I just don't understand what constitutes City driving and what constitutes Highway driving. (I wonder if it would be more accurate to look at the Average Speed per tank?) I tend to think my driving is about 50/50 City/Highway but I really don't know what qualifies as each. I live in the DC area and we have some of the worst traffic in the country, per the media.

Here are my stats on my first six tanks. This is for an 08 Clubman S, Manual.
(I didn't record all the readings for the first tank from the dealer):

OBC.... Act MPG........ Speed .........Dist ........Gals ........Grade
31.5 .................................................. ....................Premium?
31.1 .......28.3 ............35.2 ..........365 ........12.9 .......Mid Grade
31.7 .......28.8 ............35.2 ..........388........ 13.48 ......Mid Grade
32.3*......29.99........... 37.2 ..........368........ 12.27 ......Prem
32.4*......29.68 ...........35.2 ..........388 ........13.09 ......Prem
32.6*......29.99 ...........37.6 ..........400.5...... 13.4 .......Prem
(* on last three tanks, I did not reset mpg on the obc, but did reset the speed)

AC is on 99% of the time. Started using the Sport Button all the time for the last three tanks, so I've concluded that it does not affect mpg, at least with a manual transmission.

My comute is fairly consistent. I'm not babying it. (Also, the next to last tank involved an extended ride into downtown DC with pretty heavy traffic)

FWIW, I have noticed that when I ran the two mid-grade tanks, my tail pipes were very clean afterwards. When I run premium, I get a fairly heavy black soot on the ends of the pipes.

BTW, I am very happy with these figures!! I was getting 12.5 mpg with my SUV!

 

Just over 2000 miles in two weeks of ownership Had to get that darn break in done! Averaging 31mpg both manual and computer. Mix of city/country and highway. I do not hypermile my car highway avg is 75mph.
Very happy so far.
Cheers,
John

 

I think that you are on to something regarding the average speed per tank. It removes the element of subjectivity as to what city driving is.

 

That's pretty impressive mileage for the DC area. When I lived there, it seemed like 50% of my "driving" time was at a standstill.

 

Yeah, I would really like to hear what the average speed readings have been for some who are reporting 22 or 24 mpg per tank. I can't believe there is that much variation in the cars, themselves. Average speed could explain a lot.

Question: If I'm sitting in a traffic jam on 495, does that count as "highway miles"?

 

ok, you guys figure out this average.

last Sunday morning, NO TRAFFIC, I drove all over Manhattan in preparation of a MINI Rally I am putting together.

It took me 1:40 minutes to cover 17 miles!

 

That would be "highway idling"

 

Lurch, must have been all those photo ops! And good point about the stuck in traffic mode, richs10.

Definitely noticed that if my OBC's average speed for the tank thus far is at 32 or above the mpgs go up dramatically.

 

If that is one minute 40 seconds you have the fastest MINI have ever heard of.

If it is one hour 40 minutes it sounds like you were sitting in rush hour traffic.

I used to be able to do 17 miles in manhattan mid day on a weekday and do it with 5-6 stops to drop off audio gear and have it done in about one hour some time a little more sometimes a little less.

 

1 hour forty minutes = 1.667 hours
17 miles/1.667 hours = 10.2 MPH

How much time was involved for the bagel stop?

What I have seen as our in town avg speed is around 17-19mph. Which isn't bad considering the speed limit on the city streets are 25MPH.

 

Does NYC have speed/red light cameras yet?

 

Couple thoughts:

Avg. speed per tank is a good metric, but still not perfect. As an extreme example, one driver could sit a long time in stop 'n go traffic, then get on the interstate & open it up to 80. Sounds like this could be DC! Another driver may not have much stop 'n go, however maybe they also drive slower on the interstate. In theory, the average speed of both drivers could be similar, but the 2nd driver will no doubt have better mpg.

I try to look at performance by the tankful, however I also will "reset" if I know my upcoming driving will be mostly one type (city or highway). In that way I get a better idea of mpg for each type. Granted, this is not perfect either.

Finally, a pet peeve. My OBC is consistently "optimistic" by 1.7 - 2.3 mpg, and my speedometer is also high by about 2.5 - 3 mph at highway speeds. Not the end of the world, but what about German precision?? From reading other comments, it sounds like these are common conditions.

 

NO TRAFFIC??
I think you should drive the car instead of pushing it.

btw, I was born in Queens. Grandma lived on 130th Street near Liberty Ave. My mother's house was near Stallone's Bakery in Ozone Park (I wonder if the bakery is still there?) Dad moved us all to Maryland when I was 2 so I don't have the NY accent my cousins do.
