Have just returned from my usual Friday afternoon jaunt from Solihull to Stratford-on-avon.
This 35 mile round trip is along the A3400 which is restricted to 50 mph and the outward journey is always better than the return for fuel consumption, since it is mostly downhill on the way out, Stratford being roughly 70ft ASL whereas my house is 437ft ASL

Today's results are something of a record for me, (see attached photo) in that the outward trip recorded 68.5 mpg, which is probably in the order of 8 mpg better that normal. I can only assume that this was down to a strong tailwind due to the windy weather we are having at the moment.

Having said that i'm surprised that the return trip was as good as it was at 56.0 mpg
Obviously the real world figures will be a couple of miles less, but nevertheless i think a good result.

Excellent numbers, especially at this time of year. Love to see what you would have got had it been a summers day.

38, over 1,100 miles last month, Delighted.
 Mini Cooper S before produced 19 on average, 25 on a run, perhaps that was why the road tax on it was so high.

I get better mpg from my 2.0 petrol mazda 3 than my wife gets on her 1.2 honda jazz. On a run at the national limit I get get 57mpg on the display and my calcs suggest that the display reads up to 5% high. So not to shabby for a 2 litre, way better than the smaller jazz.

I get better mpg around town than I do on a run. A 6th gear would help but my 1.2 is obviously designed, primarily, for town use,

Excellent. Is that figure calculated or as displayed on the dashboard read out?

My dash reads 45.9mpg. My car has been pretty much stagnant, it's only done 1,000 miles over 2 years so I'm glad I've taken ownership of it as it has lesser miles than a lot its age, and it means I can use it for what I need without worrying about running over the clock anytime soon.

2013 si - only had it one month.

Just got back from a 1500 mile holiday, over 2 weeks. Fully loaded with family, dog and cases.

Norwich to Mull. Mull to Arran. Arran to Norwich. A mix of high speed motorway miles (c800), A roads (c400), minor roads (300).

Indicated 51mpg for the whole trip.

Really surprised at how the economy nose dives over 65. As you get towards 80mph it really drinks!

Cheers

Martin

According to the computer, 42mpg in normal use (6 miles each way to work and back each day, gentle-ish driving) on my 2010 1.4 with 60k miles, but it's probably suffering from the engine being cold for most of that.  Went to south wales in it back in the spring and it reported 49 for the trip, so there and back plus some short trips, with a full load and mostly 80 on the motorway.
Occasionally I get bored and hoon it, and I notice that takes a big chunk off the "miles remaining" figure after a few minutes.  It suspect it does not-very-many to the gallon with the performance cam profile in use.

Interesting. I'm doing a similar, albeit shorter because I start further north, trip next month. Warrington to Motherwell area for a one night stop, then over to Arran via Ardrossan and back to Dumfries and Galloway (staying in Kirkudbright).

The last longish trip I did in the UK was 2017 down to Cornwall (I had a Mk2 then) and I remember being disappointed with the mpg on the way down. 47 mpg actual cruising at an indicated 70 mph most of the way. It was wet and the other factor down there is gradients on the M5 then A38. In the same car, the previous year, I had obtained my best ever actual mpg of just over 56 mpg in the same car. This was motorway driving but it was almost impossible to reach 70 due to the volume of traffic.

Small cars are not good at high speeds - no car is really because of the drag factor - but I remember getting 67 mpg out of a diesel Golf at a steady 70 sometime up to 80 on one UK holiday. At that speed the engine was doing little more than a fast idle!

It's a relatively high vehicle so not particularly aerodynamic - a necessary compromise to provide class-leading internal space within a relatively small road footprint. Plus, if you've got the manual gearbox then the revs are a bit high for optimum efficiency - the CVT is better in this respect. If you are happy to cruise at lorry speed then you'll see much better mpg. Unless, of course, you can choose a day with a good tail wind and avoid any head winds.
