folding in the wing mirrors,
engine remapping,

What other hypermiling tricks they used would be good to know too.

So I reckon I could squeeze 60 out of a Mk3 - esp the CVT which is more fuel efficient.
My overall mpg, though, is just a tad over 44. I think the amount of short journeys I do is the culprit here. What impresses me about the AA trip is the amount of hills they would have had to climb. On our recent trip to Cornwall I was amazed at how hilly the A30 was in places. I often had to change down to third and mash the pedal to the metal to get up the longer stretches.

No problem, all you have to do is drive at a constant 40 mph with no aircon, hvac fan, or any other electrical load that can be switched off.
I thought that was what Jazz drivers did anyway!

My record in this car (a Mk2 1.4 EX) is 56.2 over 398 miles (brim to brim method - computer said 61 mpg). This was driving up the M56 from Warrington to Clatterbridge on Merseyside daily where I was having treatment. Traffic was petty heavy so I was rarely doing more than 60 mph.On a long journey, easily. When I drive to my Dad's in North Wales (190 miles, M40, M42, M6T, M5, M53, A55) I sit in lane one with the cruise control on and set to between 60 and 50 depending on traffic and roadworks. I usually get well over 60mpg doing that.

My daily commute is 12 miles. Mostly rural main road but with several roundabouts and a busy town at one end. I have to negotiate Banbury's only junction onto the M40 as part of it. During the summer I've been averaging about 56mpg. It'll drop a bit in winter but will not drop below 50.
Getting good fuel consumption is mainly about having good acceleration sense, good observation and good anticipation. The further you can drive without using your brakes the less fuel you'll use. I hardly ever need to use my brakes even on the way home at 5pm when I'm dealing with everyone else trying to get to and from the M40 in Banbury.
I have the CVT model.

Must say though, I did a lot better before I fitted the new tyres to the front.

Yes - some good advice - most of which I follow. I need to cut out these 2 mile trips. I agree with Jocko about Motorways especially if you try to maintain a steady 70, that will kill mpg.So..maintain a steady 60 :)
It probably won't make much difference to the journey time in most cases. I also find that I get out feeling much more relaxed at journey's end.

My trip last year Swindon - Scotland - Swindon in the Mk 3 Jazz (CVT) was 1483 miles using 107.33 litres = 62.8 mpg (car claimed 68.7 mpg). Predominantly A road driving 50 mph - 60 mph. [For comparison this year's Scotland trip in my HR-V averaged 53.5 mpg under similar conditions.]

They also said the wind was from the south, so they must have waited for that too.
If the car was not prepared by the dealer I bet the tyres were pumped up to maximum safe pressure and the spare wheel, jack, suitcases etc were all in the van.
I'll have to have a look and see what Guinness World Records requires for the record to stand.

On my recent trip to Cornwall I tested that out. 47 mpg at 70 and going up many hills. 53.2 mpg throttling back to 60 (ish). More relaxing drive as well.

Im able to get 3.5-3.6l/100km (78mpg) when driving 75km/h in 5th gear, with good summer tyres and perfect weather over long distance. They did it at 65km/h!
...
I have 2003 mk1 Jazz! So yeah.. with 14years newer car at lower speed, I doubt that's impossible!
Fairly sure If they would let me drive it I would have got 100+ MPG :P
