My second tank in the '07 Cooper yielded a fantastic 43.93mpg, after its first tank was 39.04mpg, diluted by a lot of idling the car did during the delivery process. I traded out of a Prius which was getting 53.6mpg (lifetime average over 40k miles) so I have hardly given up any mileage for the huge increase in FUN. Lord...how I missed a sunroof!!!

I am new so haven't seen a lot of mpg postings here. Is this good?? I think so.

"Secrets"...none really:

a. MINI Cooper, plane Jane Coupe, no S or Convertible
b. 6 speed manual, the only way to fly (I can stay in neutral down bridges and into red light intersections)
c. I am lucky...coastal South Carolina, no hills. My house is 6 feet above sea level and the office, 39 miles away, is a whopping 15 feet
d. Although tempted, I leave that "Sport" button OFF

But otherwise, I am like anybody else....come off lights aggressively, roar the air conditioner and tend to cruise about 64mph in 55mph zones

How are the other's doing, MPG???

I just made a trip from Seattle to Portland and back, kept the cruise at 75 the whole way, light traffic. Four people, with luggage in the car. My son-in-law is 6'8" tall, but he's skinny. He fit in the passenger seat with about 1/2" of headroom to spare! I filled the tank today and got 30 mpg, there was some around town stuff at both ends of the trip.

44 mpg is great! I'll have to check the mileage on a road trip with just me and my wife, I'll bet it improves.

Are you using manual method to compute MPG or OBC display? If OBC check the LANG setting in the speedo setup. Must be set LANG=US.
If LANG=UK then your display will read 7 or 8 MPG high.

 

My last tank in my S I got on avg 37mpg at the beginning I was getting 40+

 

I used the manual method, I've heard that the display is generous.

Dave

 

I see you have a newer model. Mine, I can't break 32 if I try!!

 

Thanks for that tip, and I will check, but my miles per gallon calcs are always at the gas pump, manually calculated, just trip odometer for the tank divided by the number of gallons she took.

My trip computer, on board, actually read a bit lower, about 42.4 when I pulled into the pump.

Your mileage may vary, as they say---I am very lucky. My commutes involve no rapid acceleration (like merging onto an interstate), no hills, and few lights---and the few I get, are level intersections where I can often glide into them in neutral and never have to stop at all.

I am an old timer...55 years old and lived through two severe gas shortages, 1973 and 1979. They obviously left a big impression on me!

In a just a cooper R56 that is not unusual. In fact for me I've done better. I had one trip to the dealer going 65 w/cruise and no ac where the OBC registered 51.2 on a 100 mile trip. Actual about 3-4 lower when using the pump method. And yes my language is set on US.

I recently had a trip to my wifes sister going through the southern parts of the Applachain Mountains with air some of the way. OBC =48.3, actual at the pump 45.1.

My OBC is currently showing 44.0 around town with a good bit of that freeway travel in little to no traffic.

The justacooper is capable of tremendous gas mileage. It makes me wonder how they got such a lousy rating of 38 mpg from the EPA. Originally they got a 40, then in 08 the EPA adjusted ratings to more 'real world' driving.

Currently

 

EPA ratings are averages. They are designed to be conservative so the customer does not have expectations of besting the stated values. My old '02 MCS achieved as high as 40 MPG. Conditions were 70s and going down a really long hill (i.e. mountains to shore). Long, flat roads help optimize fuel consumption. So does height. Those driving in the mountains should get better fuel economy because the air is thinner.

In any case, good gas mileage.

 

He also has the NA Cooper, as opposed to the Super/Turbocharged Cooper S.

 

I'm in the 43.93 club. JUST-A-COOPERS RULE!

 

For safety reasons, I would not recommend neutral while slowing down or down hills (or in turns).

Great mileage...

 

Are the 40+ cars on 175/65-15 tires?

 

I'm still on the stock wheels and 175/65-15s. I want a set of wheels but want to go lighter or stay the same weight. 195 and 205 tread width might effect the MPG on a Just a Cooper, I don't know for sure or not.

 

Everything I have read says MPG goes down at higher altitude.

 

Averaged 43 and change on a road trip to Detroit the weekend before last, in an S with the windows down, so I wouldn't think that is out of the ordinary in a justa. I'm on stock 16" wheels. I've hit the 43s a number of times on primarily highway road trips. In general I don't see that kind of mpg though.

 

MPG would go down at higher altitude because you're more than likely going up-and-down grades. It's not like you're going along a flat plateau. Now, The Denver area is about a mile above ground, and the right half of Colorado is fairly flat. Or perhaps atop the Grand Canyon.

The atmosphere gets thinner the higher you go. That's why jets fly so high. It allows them to burn less fuel, minus what it took to climb up there.

 

The display on my 2010 Justa says 33.3MPG right now, it has 6,500 miles on it. It keeps going up...

 

I get over 40 mpg calculated at the pump

 

I've left the onboard "average MPG" running since I bought my car...ten months and just over 27,000 miles ago. It's an '09 Cooper on the factory 15" wheels and a 6-speed. We use both the sunroof and the A/C liberally as appropriate, and we're showing an average of 35.8MPG. Not as good as some of you, but considering the way I drive (and that my last truck was traded in under Cash for Clunkers for getting about 16MPG average), I'm pretty darn happy with it!!

 

Hubs,
That is a cool Badge, do you have a real Motoring badge like that? I would like to get one to add to my collection.

 

Yes , I made it myself , We trade them checkout the Collectibles forum . Magnetic Badge thread . PM me .

 

FYI, you'll get BETTER fuel economy leaving it in gear as you coast to red lights and stop signs. It takes gas to idle when you're in neutral, NO gas is used to coast when you're not on the pedal-- the engine speed is entirely, 100% maintained by vehicle inertia.

 

I just got 33.8 mpg on a trip from LA to San Francisco and back. Lots of time spent in traffic on the Bay Bridge around the toll station. Driving up the 5 around 85-90 the majority of the time. 6MT, no cruise control, sport on, RMW tune, fat tires and heavy wheels. Not too bad! My normal drive nets me around 30.

 

I just drove to Yosemite and up to Glacier Point. It is Mountain driving up some pretty steep inclines. Drove 200 miles and got 33 miles per gallon in my S. I think thats great.
