Yes, the optimistic speedometer has something to do with European rules.
PS: I'm going to try for 700 miles on a tank tomorrow. I'm at 670 or so now. It'll be dicey.

 

Recent hwy trip, cruise control at 65mph (actual, not indicated), a/c on got me 44mpg calculated (not OBC indication). Move up to 75mph and mileage drops to about 39.

 

I've run a measured course against a stopwatch and found that 70mpg indicated is actually 66mph. 15inch standard wheels.

Also, my GPS squares with the measurement, not the speedometer.

 

I had just filled up my tank and had a week where I had a lot of highway driving to do so I decided to do a "test" and tried to keep it at 55 while on the highway. (that was HARD to do! ) I ended up averaging over 40 mpg (that was with the combination city driving) and drove nearly 500 miles on the tank alone!! As fantastic as that would be to maintain, going 55 put a crimp in my style...not to mention it pissed off a lot of Chicago drivers!!

With normal driving (city and going about 70+ on the highway), I'm getting about 34mpg and this is only with 1500 miles on the car so far!!

Overall, these numbers are music to my ears considering I'm getting double as I did with my Grand Am and saving myself about $100 a month in gas!!!!

 

Thanks to Leicaguy for informing me that wheels keep a constant diameter and to Velvetfoot that the speedo may be designed to show a bit of inflation. Best if I forget the inflated speedo in actual practice
Looks like we are consistent on our mileage reports, though anyone reporting needs to say S or non S, auto or manual, since they should be different groups. Actually, I see by the EPA page link provided here that the Cooper S manual = the Cooper automatic in mpg. The regular MINI manual is the champ. I need to read over these testimonials and see if how many high mpg's were of this breed.

 

Mine is a non-S, automatic.

 

Since there happens to be a Cooper 'S' mpg thread as well, this thread is likely for non-S versions.

Great advantage with Turbo is that you have half again or more power available when you want to pay for it, but nearly equal economy if you are careful.

First (and only) mod added to my Turbo LeBaron was a MP Gauge (boost meter) and mileage could vary from 16-33mpg depending on which side of the '0' the needle was allowed. You will see MCS's reporting from 17-45+ mpg for the same reason.

No doubt that you do lose efficiency with automatic's but the varience will depend far more on driving 'style', than it will on stick/auto or Turbo/NA.

Perhaps an Oil Company could recover some of their reputation if they were to start sponsering these; Mobil Economy Run again.

Here's a story about some Serious Hypermilers Over 100mpg

edit:- For me; Over a month and I am still using the FREE Tankful that came with my Cooper, wouldn't be meaningful anyway,
because for Brake-In of the engine, you are restricted from any "over 4500 RPM" or (Automatic) 'kick-down',
However to properly Seat The Rings (and ensure future economy) you must use non-economical High BMEP's quite often.

(Which the Agitronic Transmission allows by using Manual Mode and 'feel' of the kick-down switch.)

 

Wow, I'm glad everybody is getting great gas mileage, but I don't understand why I'm only getting 24.5 mpg. I live in Houston, and my job is about 5 miles away, and its all stop and go. I hardly ever leave the inner city. Could that be my problem. I plan on taking a trip to Austin soon, so I will see if that improves my mpg.

 

Made it.
Driving around with those four little bars is more than a little nerve wracking.

Fuel Type: Citgo Premium
Quantity: 14.255 gal US
Odometer: 5938 miles
Trip OD: 705.2
Actual Econ: 49.47 mpg
OBC Econ: 51.2 mpg

Most driving was on two lane roads, rolling hills.
Some highway, 100 miles?, but can't quantify.

 

Yes, see if you do better on your trip. Fuel economy isn't great until the engine reaches operating temps and it's barely had time to do that in a short commute.

Nice!!!!!!

 

I have an 07 MC with auto trans, 15" wheels. After 11,000 miles of mixed driving I am averaging 37.191997 mpg. I am not heavy footed. I have been driving very conservatively of late in an effort to give the oil companies as little of my money as possible. On the highway I drive between 65 and 70. I get passed by most including the huge pick ups and SUV's gulping gas at 10-12 mpg.

 

BMWBOY, from what I've seen so far on the boards, that looks like pretty good mpgs from an automatic. I bet it's more tricky going for high mpgs on an automatic compared to a manual. I wouldn't know where to start except to use a velvet foot . I thought I've read that coasting in neutral in an auto is not good for the transmission.

 

That is phenominal mileage. I will never attain that. You shouldn't take the risk of running out of gas though, it's not worth it. I usually drive 60 to 70 on the highway, it depends on what the other traffic is driving at. I think the biggest thing that helps mileage is keeping the tire pressure up to 37 psi. I didn't buy this car for gas mileage, I bought it for fun. Gas mileage is just an added benefit. I usually average around 40 mpg but there is not a single fill up that goes by that I am not revving it to at least 5k some of the time. If I am getting on the highway with nobody in front of me I am going take advantage of that.

 

I had a can of gas with me before it got down to the bars.

 

But what about the extra weight?!!

Sometimes I have to blow the mpg for safety's sake - crawling out of of junctions or passing a truck on the highway at 0.5 mph difference just can't be done all the time.

 

Now y'all need to tell me if I'm nuts or not when I say that I think the tank of Exxon fuel I'm on right now is giving me a lower mpg than Chevron or Shell. With Shell and Chevron I could swear I'm getting 1.5mpg more. I realize that could be accounted for by driving manner, but I have been very careful to try to do all things the same.

Has anyone else noticed anything like this? If not, perhaps I am not controlling the human variable as well as I thought. I don't want to believe that since I have always taken pride in being a maintenance test pilot for various aircraft. Maintenance flying demands a minimization of pilot-induced variation. But, who knows?

 

I think so too.

 

There's a good chance. When I was at Lotus HQ last Decemeber, the drivers there said to be a good test driver you don't have to be quick, but you have to be consistant (they were both as it turned out!)

 

My '07 MC manual with 10k miles has consistently averaged 42-44mpg every tank. Latest tank was 44.8mpg. My commute is about 60/40 hwy/city driving.

 

Welcome to NAM!!! I get similar results...have about the same miles on my '07, too.

 

Thanks. Great message board.

My style is just to throw it in neutral anytime I see a red light or other need to stop or when going down hills.

 

I am about to turn over 10000 miles.
OBC AVG MPG = 42.3MPG
OBC AVG MPH = 47.2MPH
Hand calculated MPG = 39.7MPG
I have a conservative driving style. Very little 'city' stop and go driving. Almost all my driving is at relatively constant speed on rural roads which is probably an ideal situation for getting good fuel economy. Most driving at 6000+ feet. Using mostly 91 octane Philips 66 gasoline.

 

This guys got it right. I get 38 to 40 consistently with my Clubman. The best I've done is 45 ( too much work and a lot of coasting ). The worst I've done is 35 ( a different kind of fun ). I think I could get it down to 30 if I worked real hard at it.

 

My husband has a Nissan Sentra Spec V and notices that different brands of fuel makes his car perform differently (different MPG being one of them). I've only filled up my tank 3 times so far and have always used BP. (we have a BP station near us that always has the lowest gas prices around)

 

I went from north Jersey to Rhode Island Friday night, about 205 miles. There was no traffic and I mostly did 70-75 mph though let her go at 80+ for a while now and again. Hit 90 too. I had two passengers. Made two rest stops. Twas highway driving all the way.

Normally, it takes a third of a tank of gas one-way to Providence, three hash marks on the fuel gauge. But Friday night I expended only 1/5 tank (two hash marks). Before I set out I topped off with, for the first time, Shell premium, 2/5s worth.

The return trip Sunday night, likewise traffic free, took the usual third of a tank. Next time I do an out of state trip I'll fill her with Shell again and see what happens. Perhaps Friday was a fluke.
