    the best we can do is about 26 mpg in pure city driving. Have not taken it on highway to establish highway mpg.

    I'm getting about 27 mpg in my '05 Cooper S. That's during an average commute-filled interval between fill-ups (between 9 and 11 days). I did get 31 mpg on a road trip once. I was doing about 75 with some spurts up to 90 during a 6 hour trip.
  • I am on my 4th tank on my 04 works S. I am using mid-grade for last 2 tanks, and I got 28 mpg average on one tank by keeping my foot in the supercharger. The next tank I averaged 35.1 mpg by driving posted speed limits and keeping it under 3 grand most of the time. My personal best was 42.6 mpg on 50 miles of hilly interstate, 65 mph, cruise control on.

    60k miles to mpg 38 worst 31 . I average 34 mpg most of time with my 100 mile a day commute and doing 70 to 75 mph. Could probably do better if I followed speed limits :P but this car keeps telling me to "drive it".

    Prushing, are you going by the on board computer readout or real world calculations? 42mpg is oustanding, especially for an "S"

    I should qualify my MPG. It is based on real-world solar-powered calculator button-pushing after each fill-up (Tripmeter/Gallons).
  • My new job requires me to drive 100 miles a day...
    I am looking for the best MPG with the CVT and was wondering if I should get the base, S, or Works. If getting the S means I only lose a couple of MPG then from what I hear its worth it. Thanks.
  • akitadogakitadog Posts: 117
    The CVT only exists with the base Cooper, not the S or Works (which is an S). The S automatic is a six speed conventional auto transmission that also allows for paddle shifting and autostick-type shifting. I think the S auto is down to 30 mpg highway (vs 32 w/ manual). Cooper CVT is 35 highway, if I'm not mistaken.
  • I am looking for a competition head, camshaft and straightcut gears.
  • 2003 Cooper S JCW+other mods 6spd

    all depends on where/how you drive

    Agressive driving, daily commute of 60 miles on highways at 80mph at 3200rpm average 27.6mpg

    timid, 70mph/highway average 31mpg

    granny driving average 35mpg

    Base Cooper with CVT, according to on board computer have gotten 27.3 mpg overall on premium fuel for 9400 miles. With long trips the calculation has gone as high as 27.6, but fell to 27.3 with more in town driving. Of course freeway trips often see a speed of 80 mph

    A little over 27,000 miles on my 2004 Cooper S right now.

    When I was driving back and forth between CT and VA twice a month I could average over 35 mpg for the whole trip. I only drive my MINI on weekends now since I have a company car but before I got the company car I was getting 25-27 mpg in pure city driving.
  • We have a 2003 Mini Cooper M/T with 35K miles. I've let the MPG run for long periods of time and it always has settled in at 29 to 31 mpg. The car has been driven 15% urban 85% highway and mostly unspiritedly. Best Milage was a trip from WY to CA - 37.9 mpg. This was speed limit driving on the interstate w/cruise control.
  • For the Base Mini Cooper, is it really necessary to run premium gasoline?
  • Just took a road trip - about 210 miles each way - in my new 2007 Mini Cooper automatic basic model (not an S).

    I had been getting 26 in pure city driving without any highway, just as advertised, with lots of stop lights and above-average accelleration on my part with the A/C on.

    On the road trip, I paid close attention to mileage and how I drove. The best I got was a stretch of 90 miles at uninterrupted speeds of 40-55. During that stretch, which included some hills along the shore of Lake Superior, I got 38.8 MPG - and I had the Mini-bike rack with a mountain bike on the back. I don't know how much of a difference that made, but I guess maybe I could have come closer to 40. I got very close to the same mileage on the way back during that same stretch. On the entire trip back, it averaged 33 MPG, which included two bikes on the bike rack and higher speeds for the other 65 percent of the trip once I got on the Interstate.

    Without a doubt, mileage goes down pretty quickly at speeds of 65-85 MPH, and is ideal between 40-55. But at 70ish MPH, it will get in the 28-31 range with two bikes on the rear bike rack slowing me down.

    I haven't experienced winter driving yet, but in Minnesota it should be interesting after being used to a Jeep Grand Cherokee the past ten years.

    At 6-3, I was very comfortable in the Mini for my first long road trip since switching from the roomy Jeep. Very fun car to take on a road trip. I changed the steering wheel (which moves up and down, plus in and out) and seat position to a few different configurations to change things up and was comfortable each way. Great car so far in every way.

    I got lots of smiles and nods from drivers on the road. I think people were amazed at seeing two bikes being toted in such a fashionable way with the great bike rack that can be custom installed. (Be sure to pull those bike tire straps tight, though!)

    The Bike rack actually acts like a wind brake and will really decrease your fuel economy even if it's just the rack with no bike in it, less so in city driving. Cops lose at least 4mpg by having a low profile light bar on their cop cars. But I'm sure it's worth it to be able to haul your bikes on trips.
  • I average 35 mpg on my 2007 mini. I tried 87 octane instead of 91 and it dropped to 31 mpg. Needless to say the cost savings of regular vs premium does not justify the lower mpg.
  • I am looking into purchasing a rear bike rack for my mini. I was wondering if you had any advise as to what kind to get. Did you purchase Mini's bike rack or another brand?
  • I bought the dealer bike rack. It's sleek and really secure. I didn't even consder any others. It holds two bikes on the back for minimum wind resistance. I drove two mountain bikes on a 150 mile each way trip this summer and it held up nicely. The straps are less convenient (it takes a little more dexterity to really tighten those tires on the rack), but once you get used to it, it's not bad at all. I'd recommend it.
  • I consistently get 30 mpg with mixed driving (including bumper-to-bumper) and lots of WOT. I've seen 28 with lots of AC and seen over 33 on longer drives.

    I have a 2006 Cooper S and given where gas prices are going, I want to know if anyone out there has tried burning regular gas in their Cooper S. If so, what were the results? I've been told, that the car's computer makes adjustments for the octane being used, but that information did not come from a Mini mechanic.
  • waterflamewaterflame Posts: 22
    Actually, the Mini salesperson told me this as well.I'm not sure what the mechanism is, but I think the onboard computer gauges the octane content of the fuel and makes adjustments accordingly.Not sure how it would affect acceleration or efficiency.

    On a side note, the difference between premium and regular is usually about 20 cents, which means that you're spending about $2-3 every time you fuel-up. Unless there is a significant difference to be gained in mpg by using regular instead of premium fuel, I don't see much of a saving over a year.
  • morgan5morgan5 Posts: 13
    Around here (Virginia Beach), the difference between regular and premium is more like 25 to 30 cents, but I agree with your assessment waterflame. Thanks for the reply.

    For my non-turbo mini I have been fueling with 89 octane since 91 is not avaiable at all pumps in my area. For grinns I called the dealer service center yesterday to get their opinion. Before the mini I had an 01 Passant and it stated I had to run premium 91 Octane, but the service center said 91 Octane is he Euro rating and 89 Octane is the equivalent here in the states. However, the Mini service center said for the mini 91 is a minimum, but you can also burn whatever you want. What might happen is you might get a check engine light, and in the long run the regular gas will not do well for the valves. Since regular gas for mini doesn't burn as efficient as premium you will see a carbon build up on the valves which means down the road you may suffer with worse performance than just the loss of MPGs.

    The onboard computer on my '05 BASE convertible, 5-peed manual, calculated 35.3 MPG. I did not reset it for six months. I ran premium fuel per mfg recommendations.

    My '06 S, with a 6-speed yields just 25.2 MPG. I drive it hard and sporty, if you will.
    I use, per MINI (and BMW and Honda (maybe toyota)) Shell. They also recommend Cheveron and I think Phillips66/Conoco as THE fuel that meet their specifications but only SHELL is available in my area (Boston).

    The above mentioned companies collaborated and recommend those fuels for their engines.
    Much has been written about engine performance and durability relative to fuel and fuel additives. It goes way beyond performance loss/gain. Most important is cleanliness of the fuel system and specifically the injection system.
    I plan on keeping my MINI for a longtime and want to see how long it will last!
  • My top mileage for my Mini '07 (the lower priced model, automatic transmission) was on a recent 250 mile road trip. The peak MPG was 44.9 for about 150 miles of driving in the 40-55 MPH range on a highway with zero braking. For the entire 250 mile trip, with some 65-75 speeds, averaged 42 MPG.

    The cool part is for the entire trip I drove behind a Prius. The Prius got 47.5 MPG when I got 44.9 (I tried so hard to get it to 45 but I had to pass a car right at 44.9, and speeding up cost me that final tick) and for the entire trip, the Pruis did only 3-4 MPG better than the Mini. Pretty impressive. I drove it very carefully without A/C and almost no braking the entire trip. Just two passes at higher speeds.

    Otherwise, in mostly city driving, I'm getting in the 27-30 range in winter and summer with A/C running. With heavier highway driving, I'll tick up to 31-35 for the whole tank. The 40-plus is certainly the exception, but for a long road trip, absolutely possible. The key, though, is keeping the speed lower than you'd typically want, so it's a tradeoff going 60 instead of 70 in a 70 zone. I typically wouldn't be so worried about losing a few MPG ticks to get somewhere faster, but I wasn't in a hurry on this trip and wanted to test the absolute limits of the MPG in perfect flat 60 degree no rain no braking driving conditions.
  • Last summer we drove our 2006 Mini Cooper from a small town south of Houston TX to Phoenix Arizona and back with an overall average of 41.5 mpg. We also mostly drove at 60 miles an hour just to see what optimum fuel efficiency could be. Generally we get 36 - 37 mpg per tank commuting 20 miles to work.
    This summer we get to try with our mini clubman s which won't want to travel at 60 mph.
    Am looking for a 40mpg club bumper sticker.

    Everyone talks about highway miles when discussing MPG, but I'm more interested in around town driving. My daily commute in my 2006 S is about 15 miles in stop and go traffic (no interstate or highway). Usually, I get about 22 to 23 MPG around town. Now that the temperature is getting hot I am running the AC most of the time and my MPG has dropped to 18-19. Is this normal?
  • I've gotten 28 MPG under the worst of conditions - super-short stop and go trips with A/C on and somewhat fast acceleration. I'd say that's the bottom in the "entry-level" automatic transition model. It probably gets better as the car gets more broken in. That is using high octane gas. You don't want to use lower octane or it'll drive poorly at slow speeds, such as in parking lots, where you'll think there's something wrong with the car as it seems to search for the oomph to get going.

    Minidrivermn, are you driving an "S" with a supercharger, or a regular Mini?
