R56 AT Fuel Economy
 

While I had the MY R56 with a MT I was getting a minimum of 31.5 mpg around town and about 36 mpg on the highway. That was for the entire time I had it up to the 3000 mile mark where Mini took it back.

The new car has the AT (which I like much better, for convenience sake) and has been dissappointing at the gas pump.
Fill-ups have been producing a declining mpg figure consistantly since new.
28.5, 27.5, 26.5, and today 25.5 mpg.
I haven't been beating on the car (yet) and was expecting at least 30 mpg under light-traffic commuting...
The trip computer is optimistic between 1/2 and 2 mpg, btw.

What are other AT drivers getting? I'm at about 1400 ft above sea level and using top shelf 93 octane fuels (QT, Shell, Chevron).
The car has a little less than 1000 miles on it.

Around 28 mpg over 3000 miles.
Though half my miles are technically on the highway, even those are short bursts, so I guess my driving all counts as pretty heavy city driving.

That's an MC, you're MCS arnbut? Hopefully your decline is some odd coincidence!

Yes; I have an S.
It's getting the same mpg's as our R53-S right now...

Checking your tire pressures would be my first idea. Could have been low from the get go. Temperature and AC use effects mileage also so that could factor in.

wow.
My R53 w/ MT gets 31-33 highway, and I've pushed it up to 35+ when forced to go slower behind a tractor-trailer crossing PA on 80...

Right, as above, maybe it's gotten hotten and hotter and your AC is higher and higher?!?

Tire pressures are checked cold with religious zeal --- 33psi all around on the 16" runflats. It's been 100 degrees around here lately so the A/C is on most of the time.
I knew that I'd be trading a few mpgs going to the AT but I didn't think it would be more than 10%...

Automatics consume more gas then manual transmission and cause more brake pad wear. This is nothing new. Your fuel economy number with MCSa seen resonable when commared to MCS 6-speed.

R56 MCa , 32-34 mpg mixed driving with 93 oct and AC on.

If I do a lot of stop and go traffic with temp's in the +95F range, mpg's suffer greatly.

I have been averaging 26.6 mpg around city streets, 29 mpg with light freeway travel. What I have started doing is picking my shift points myself, we'll see what the next fill up reflects...:wink:

I can go just as far as my previous 4Runner, not to shaby!

27.5 mcsA driven agressively air on--mix of city and highway.

I get about 27 mpg on mixed driving.

26-28 mostly around town. Do a long freeway jaunt and can easily get 32+. The is an '07 MCSa

Just got an '07 MCa, picked it up in Denver, and drove it home over the weekend. Trip was a little over 1,100 miles. The OBC reflected 38.2 mpg, while my manual calculation was 36.3 mpg. I was at 65-75 mph most of the way, and estimate the AC was used at least half the time.

MC manual routinely get 37-38 in mixed driving around town. Fill up this weekend was 39.8 with about 200 miles of interstate travel. All by fill up, OBC 1-2 mpg optimistic.

I'll have to agree with the recent heat points. I have noticed a decline in my MCS from about 32mpg mixed driving to around 29mpg or so. It's been pretty consistently hot here recently (>95F). Light A/C use (2 notches on). Not too aggressive. Have filled the tank up again for another calc. Will let you know.

I suppose I do employ the turbo a little too often...
Nothing seems to be wrong with it; I'm going to motor today. I'm finally over the break-in mileage (a very long 2 weeks) and I might just thrash it a little.

With only 1500 miles on the car so far, I am getting 28-30 in mixed highway (lots of stop and go traffic) and city. I did one short trip of 120 miles with all highway and got 37 miles per gallon.

I am getting about 27mpg mostly freeway but with LA traffic and MAX AC most of the time.

MCa: at 3500mi on the clock, i'm getting about 28 - 29mpg consistently as a stop-and-go commuter. highway trips have seen 38 - 40mpg.

32.5 mpg yesterday with mixed real-world non-commuting driving. This included some very naughty behavior in the mountains on the ultra-twisties and some mundane 4-lanes and a little interstate.
Looks like the R56-S just doesn't like stop-n-go commuting traffic and will punish me with poor fuel economy when I force it to do that duty.

Arnbut , since you have had both mabey you could start a post comparing manual and automatics ,is it as fun , is it as fast etc...I test drove an automatic non S it seemed a little weak but I did not use the sport button and I did not push it to hard .

my 07 s auto trans gets 31.5 in mainly suburban traffic with ac on most of the time.

I just got 36.3 MPG on a 275 mile trip in my MCSa a couple of day ago (it was 37.3 there and came back down on my way home). When I started, I had about 900 miles on her. She has been steadily improving her mileage as she gets more miles on her. I have been getting about 27 MPG in the city so far.

I do keep the auto AC on all of the time.

You sure they didn't forget to put the turbo in your MINI? Your mileage sounds more like an MC than an MCS. :eek: :grin:
