In Germany, my '04 MCS and my '07 MCS got around 29 MPG...but I was also averaging about 90 MPH or more. (No, not kidding. Man, I miss Europe... ) In the US, I usually average about 65-75 MPH (unless I'm feeling invisible, and then more!!!) and the MPG hangs around 33-35.
Some things you can pay attention to, in order to help the MPG (on any car, not just the Minis):
1.) get services, oil changes, and tire checks/balances regularly -- and use the right products on your baby
2.) keep your tires inflated to the standard PSI (cold or hot weather determining - check out your door data plate to be sure of what that is)
3.) Try to keep your gas tank at 1/2 or more -- for some reason the MPG is higher when there's more fuel and less movement in the tank.
4.) Downshift instead of immediately braking. This can be a lot easier said than done, if you're in traffic and would rather have your tail car see your brake lights than kiss your bumper, but it really does help. THis is what Jimmy_racoon was talking about re: acceleration/decceleration. The more your punch the accelerator and the more you slam the brakes, the more gas you're using.

I don't know about everybody else, but when I use cruise control on any of my make vehicles, it really doesn't do the MPG any justice. Between my 4x4, my Mini and my husband's BMW (I swear he uses cruise control to roll five feet!!!), my two vehicles have a relatively speaking on-average higher MPG I prefer to free-foot it, unless I can't help it for brief periods on long trips.

 

Another thing that affects mileage: altitude. With a fuel-injected engine that corrects for ambient pressure, you'll see a jump in mileage if you get way above sea level. My BMW motorcycle (normally 51 mi/gal) got over 60 mi/gal when I spent a week over 7,000 ft. in Colorado. Power will be slightly down, tho.

I get 32 LO----34HI mixed driving in my MCa.

 

First fill on my 08 MC 6M returned 33.8 mpg, calculated manually. OBC said average speed 28 mph.

 

I am driving mine hard and fast and getting 30 mph. I guess mine is good.

 

Recently, I have been getting about 27 MPG, with an average speed of 24 MPH, mostly in-traffic driving. I consider that great, especially since I am decidedly not a lightfoot.

 

My last 2 tanks OBC avg speed 48.7, mpg 34.2 hand cal to 33.2 on my '08 MCS manual with 2k mi. Still much better than the 28 I got during my 88K in my '03 MCS.

 

I've seen that same thing as well with my CBR 929. I get 38-40 around here, pretty much sea level, but on trips I've taken through the Sierras (like Yosemite), I get 55-65. I was wondering if the Mini would do the same. I haven't taken it up to high altitude yet.

 

08 MCS 6 Speed 2800 Miles. Second Oil Change. All Stock: 33 MPG, 34 MPH Avg Speed. Altitude, 6000 feet. And I drive up a mountain road every day to work. In pure highway driving (Cruising at 70-80) I calculated 38.8 MPG.

 

Wow, that is fast! Only 35mph under speed limits on most interstates. Guess you mean mpg.

 

8500 miles. Mostly open highway driving above 6500 feet.
OBC MPH: 46.7
OBC MPG: 41.7
Calculated MPG: 39.4

 

32.2 mpg.

The funny thing for me is it depend on how I drive. I normally get around 30 on average in my 08 mcs. But if I am specifically going for mileage and make sure that I am behind someone I can see 40 mpg. I filled up early on my last tank full just so I don't ruin a 40 mpg tank. The obd indicated 38.6.

 

Wow, I think that's great for an MCS. I've gotten 43.3 and 42.2 in two tanks so far on my MC. That's driving conservatively but on a fair amount of hills and not too much highway driving. The last tank I could feel a performance hit from using regular fuel, but still didn't take too much of a penalty on mpg. Using premium this tank.

 

30 between city and highway

 

34 avg. after mostly city driving, 37-38 avg. after mostly highway. I'm sure it'll go down due to my driving once I am past break-in! So frustrating keeping under 4K rpm!

 

I've got an MC. I'm getting 38-39mpg over six tanks. 3600 miles, now.

My OBC consistently tells me I'm getting 48, but fill-up calculation indicates the lower average.

Any ideas why the difference? Anyone else have the same experience?

 

You may have your obc set to english uk in stead of eng us. The uk gallon is larger.

 

I have found my obc to be 1.5-2 mpg optimistic.

 

My MINI this week is getting 33.7 and I only drive in the city!

 

Wow....I was happy when I could get 21-22 mpg city in my R53!

Can't wait to be getting almost 10mpg over than that in my R56!

 

I'm just over 2,600 miles, and have not done worse than 35 mpg. disclaimer-- the nearest stoplight is about 41 miles away...

 

I've been on the WV twisties. You must not drive like I do!

 

We still have gravel and grit being laid down by WVDOT. It snowed Sun and Mon here... Not much fun taking the twists fast on ball bearings...

 

I'm getting better than twice the mpg of my other vehicle -- a Jeep Grand Cherokee with a 5.2L V8!

...And the Mini is oodles more fun to drive!
