138.3 at the moment....

 

I am doing 39,984 Miles per gallon (US) [MPG] with my 1.5 3 cylinder countryman with 103 horsepower.
it’s great. With winter weather it went a bit down but still better than my SE i had before when calculating electricity and gas usage together.

 

I had a 2018 JCW Countryman (manual). I actually ended up selling it to Carvana today. They gave me $28,878. I thought that was better than Carmax appraisal for $24k... Anyway, yes we are talking about mpg -- What I got I thought was terrible even for the short time frame of having the car (little less than 11 months and with covid and working remote, I drove it maybe a total of 6 months). I do all highway driving and the best I got was 23.8. I think that is terrible for a 4-cylinder turbocharged motor -- I understand that its a little bit different since it is a tuned JCW motor compared to the S, but still. My 09 R56 S to this day gets better (30 mpg). My 2014 Audi S4 gets 27mpg and that motor is a 6-cylinder supercharged. I don't get it. I think being its based on the X1 platform really screws it up. I found plenty of other things I like and hated on the car, but I hated more than I liked or loved for why it went. I will stick the 2-door R56 Cooper S. I know the peugeot motor is awful (N14) and surely has its problems, but it at least gets good MPG lol. I think overall I am not fond of SUVs (or SAVs [sport activity vehicle] Mini calls the countryman). It was also a shame the R60 and F60 didn't catch on in the aftermarket world, not like the coopers and clubmans have (this even for coming out in 2010). Anyway, you didn't read this thread for my likes and dislikes so, I will stop - But mpg on a JCW Countryman is bad.

 

My 8 speed auto JCW Countryman, 2019, gets in the upper 20's even with some wide open throttle runs. If I keep it under 70 mph, its gets just over 30 mpg with a mountainbike on top.

 

Finally found the issue. My car threw a CEL. It was the fuel tank vent valve that needed to be replaced. So far so good.

 

My 2019 Countryman S has never gotten close to its EPA estimate of 23/32/27. From my fairly regular calcs I would put its aggregate city at 19 and highway at 26. Pretty bad, relative to its estimate. In contrast, my 2006 Cooper has thrashed its EPA estimate for every tank of its 230,000+ miles. My Countryman is in for an oil change today and it will be the second time I have registered a compliant over lousy mileage. I am not expecting a substantive reply from the dealer but I do wonder how others have faired when raising the same issue.

 

Our new 2022 JCW Countryman is averaging 27.8 mpg right now with a mix of highway and city. Since it is new as well, we haven't gone easy on the acceleration as it is just so much fun to drive.

 

2019 F60 Cooper S with Dinan Elite and Eventuri CAI.

I'm averaging 20-24 because I have a heavy foot and I like it that way. No complaints.

 

I had to replace a fuel valve sensor that threw a CEL. I was complaining about my mileage dipping prior, they said I had a heavy foot since installing the tuning kit. It’s gone up from 12 to 14.5 L/00 km since.

 

2020 F60 JCW MPG 10,649 Miles / 378.35 Gal. = 28.15 MPG

 

For the first 1000 klm
I got in highway with a/c ON
1. 5.4 l/100 with avg 100-110 km/h (300km journey)
2. 5.8 l/100 with avg 110-120 km/h (300km journey)
3. 6.1 l/100 with avg 100-120km/h but with heavy traffic in last 100 km (300km journey)


I got a 102hp manual Countryman ONE 2021
