Ok, I'm going to play, although my modern is probably too new to be counted, a 2010 Panda 1.3MJ.
Tank to tank average recorded over the last 120K miles sees it at 64.43mpg, with a best and worst tank to tank recording of 79.65mpg & 52.85 mpg. and it's not always driven like a chauffeur-driven car either lol.
Definitely an underrated future classic lol

My old fall back the 56... 454 Big Block dynoed at 500+ HP give or take 5 speed DNE 4 +1 where 5th is 1-2-1 9" Ford axle with a 3.25 ratio and 28" tall Mickey T's Drove from home to the Hot Rod drags, so around 160miles each way, ran more than 10 1/4's all in the 12 second range with a best of 12.2 @ 118 and then drove home at around 80ish. From memory 18mpg. I would say that was money well spent - even got a Trophy! P.

Since I stopped using it as a daily, around two years ago, consumption has leapt to an average of 12mpg. Prior to that, it was 8, at an average speed of 5mph. To be fair, a long run, up to Subic Bay just after I got her saw 16-ish and that was pre-new plugs and leads. Did another to Matabungkay after things were fully sorted, but was playing silly buggers over mountains and off-road, so that doesn't count!

I got slightly over 40mpg average from my 98 LS400 on a trip from the North West to London and back with a bit of bozzing about in between.

Range rover does around 14mpg on a decent journey even 16 on a long run but use it around town on short trips and it drops to single figures.
my elan is surprisingly good and does well into the 30's much the same as the MX5, TR7V8 does mid to high 20's if I drive it sensibly.
Most surprising was a low roof Transit custom which averaged over 40mpg on a long run.

Mapped Bora 150TDi running from Aberdeen to Chester saw 70mpg. Also had a mondeo ST TDCi that would do 65mpg on a cruise control run. I've had a few cars that would stay in single figures on a spirited drive, one was a 450bhp Pulsar GTI-R and the other a 475bhp Sapphire 4x4 Cosworth. Current fleet do quite well the daily D40 Navara does 38-40mpg running round on 33" tyres with a 2"lift, swmbo gets 28mpg running round in the Bora V6 4motion - although I can tip that into the teens and over 30mpg.

I had a really good run there and back and was able to use cruise for the majority. They're good on fuel! I'm getting around 20mpg average from my XJ8 and got 26mpg from my LS400 for the same commute. 0.8 litres and 60bhp more on top!

I have an Insight so I’ll probably win this competition.
Best I’ve managed was 114mpg door-to-door on a 57 mile journey. Not bad for a petrol auto. I know the manual can do better than that with nowhere near as much effort. Normal average on that commute was 76mpg tank to tank.
Same route, averaged 55mpg in the Citroen Ami and 42mpg in the Anglia.

I've grown to measure it in smiles power gallon - that way it never upsets me!

I've grown to measure it in smiles power gallon - that way it never upsets me! A good way to look at it. It is possible to do ok on both fronts though. In 1988/89 I built myself a Triumph Vitesse out of a heap of parts from a number of donors. I still have it and it's been in continuous use for the whole 31 years, covering about 85k in that time, more than half of that in mainland Europe. Up until about 2004 it ran the standard twin Stromberg CD150s. Average mpg was in the mid to upper 20s. Lower to mid 30s on long runs if I was not too heavy footed. Once got into the upper 30s pottering in France, but apparently it was a bit lean as it cost me an exhaust valve. In all, fairly respectable for a 60s 2L. In 2004 I built it an injection system out of exhaust tubing, miscellaneous hardware from various cars and a Megasquirt MS1 ECU. It was an exercise in how cheaply I could do it and intended as a prototype. It remains on the car pretty much unchanged, though I did add 3D distributorless ignition the following year and upgrade the ECU to an MS2 in 2009 as I wanted barometric correction so I could play in the mountains. Until 2015 the basic engine was as Triumph built it and it made about 115 bhp, up from 104 bhp. It then averaged lower 30s mpg in general running about, mid to upper 30's on longer runs and has been known to crack 40mpg if I can manage to be nice to it for a whole tankful, which normally requires the supervision of senior management. In 2015 the engine was replaced with a slightly fiercer one. Maybe has 140 bhp now. This meant remapping the ECU, but the hardware is unchanged. Could do with throttle bodies now as the cam is a bit lumpy for a plenum. The mpg overall hasn't changed all that much, but the wilder cam means there isn't much point in pottering about as it's no more economical than it is when being given a bit more welly. It rarely returns less than 30mpg, but after all these years, there have been a few "landmark tanks" where sub 30mpg indicates a certain amount of fun being had. The all time low was 21mpg, the result of some really determined big-bike chasing in the Alps. In fact a number of low 20s tanks resulting from Alpine fun. The tank that included a flying lap of the Nordschliefe (basically 13 miles at full throttle in that car) was somewhat sub 30. Surprisingly Castle Coombe trackdays have proved less thirsty than the Alps with typically 24 - 26 tank average with a 80 - 90 track miles in it. The pic below shows the old dear at 2,800m on the Col de Bonette. Actually she was sulking there having been inadvertently being given E10 (bad) with significant water content (worse). She got a top-up with V-Power at the next opportunity (not normally allowed the good stuff) and normal service was resumed, allowing us to go and play on the Col Du Turini. Pretty sure that tank was sub 30...... Nick
