Quite the challenge! Good luck with it if you decide to try.
Even with the 42L tank actually holding closer to 45 litres, this is basically double the challenge that the A8 faced, you're going to have to average 80mpg. The rule of thumb for a TDI75 where long-run MPG = 130 minus your cruising speed, says that a TDI75 might be able to do this at 50mph. An interesting proposition! Are you going to go straight for 'van mode' to lose the weight of the rear seats and false floor? Any other modifications? Good luck
Tape up all your panel gaps and consider some kind of shroud over the rear wheels.Well I’m running a remap with JDD and a set of pepperpots coming tomorrow with new tyres to be installed on Wednesday. I will be taking out as much weight as sensible and keeping it at 50-60 as much as I can. I can sit at 30mph at tick-over in 5th but that would make the journey around 24 hours! Any other tips?

Surely at 50mph you'll die James - if the lorry driver scrolling on their phone doesn't get you then boredom will!

Choose tyres with low rolling resistance. From worst to best tyres this can differ fairly much.Well I’m running a remap with JDD and a set of pepperpots coming tomorrow with new tyres to be installed on Wednesday.

What's the map you're running? That's impressive mpg. Jdd is the long geared box isn't it.That is on standard 16” wheels with full weight and 2 occupants.

Interesting reading on tyre pressures from cycling world. It used to be thought hard tyres were fast but absorbing bumps and not letting the impact disrupt the forward momentum proves more efficient, so I wouldn't go too hard on pressure, unless road is like roads in France!
I reckon my 1.4 petrol with full tank, 34L I believe, would give Well, at least the access to the egr is less headache lol.
On the track/velodrome we would run as high as possible 168-180 psi always.That’s about the same tank mileage as I get when I’ve mostly been driving on long journeys. If I tried hard it would crack 625 miles.
Not sure about that bike tyre theory Ed….
The more bumps you hit the better to have correct pressures not high, as in cycling hard tyres over bumps equals backward and up motion. It would be a marginal gain on glass roads. see this article for pumping up high. https://www.popularmechanics.com/cars/a940/4199963/That’s about the same tank mileage as I get when I’ve mostly been driving on long journeys.

Indeed on glass smooth suraces where its only required to move forward at high speeds. At low speeds on bumpy roads you will loose, imagine on a gravel road on that same bike. Either way be interesting to see what Brooms achieves and loko forward to his threadOn the track/velodrome we would run as high as possible 168-180 psi always.
