What is the record for longest distance of a production vehicle using the factory gas tank?

[slurp812]

I had a 1994 Honda Accord with a 2.3 L4. Fairly large 12 gallon tank. I got 600 miles on a tank once. High 500s regularly.

Guinness says 2,545.80 km (1,581.88 miles): https://www.guinnessworldrecords.com...ange-(standard)

Officially (Guinness World Records) it is 1582 miles driven in Croatia in June 2011 with a VW Passat 1.6 TDI. The vehicle was driven until it ran out of fuel. Yes this record could be beaten: I drove a OPEL Insignia 1.5 D around Germany in October 2022 with 'less than a tank of fuel' over 1526 miles (start and finish at the same pump station in Ruesselsheim, still some reserve fuel in the tank). Both cars have a capacity of ~ 20 USG of usable fuel in their factory tanks. OPEL was not interested in a new record since they stopped production of that ultraefficient 3 Cylinder sedan this year.

Even though I am favorable to that 3-cyl layout, as it's at least supposed to be more efficient that a 4-cyl with a similar displacement, that engine having been made was quite surprising. IIRC it was only released well after GM sold Opel to PSA, even though it having identical bore and stroke to the straight-6 currently fitted to the Silverado 1500 would've been a good reason to consider using it in the Chevrolet Cruze, Equinox and Trax instead of the 4-cyl 1.6L which used to be available on them.

I should be able to hit 1,600 miles with my 26 gallon factree tank. Assuming I can keep it running that long and did some long trips. The Passat TDI wagon has a 26 gallon tank but they limited it to a 21 gallon fill by using a vent cut off system, since the gasser version Passat Wagon used the same tank and gas is more volatile and can't be filled to the top and needs some volume for expansion of vapors. With a ventectomy (removal of the vent cut off) I can get 26 gallons in by filling up to the filler neck. I could never get a legit record with this vent mod. If I use only 21 gallons I couldn't hit the record.

The more you put in your tank, the heavier your car gets

2007 RAM 3500 4.1 gear 6.7L on a good day will get 26 but usually 23 very temperamental to weather conditions in Houston. That's at 58 mph and cruse to work on I-45. Totally filled 55 gallons so at 23 would be 1265. Has a 4k steel flatbed on it for hauling.

Sometimes it's important to weight the benefits, when there are fewer gas stations on the route or if you don't want to stop so often for refuelings

Not a record distance by the above, but my insight only has a 10.6 gallon tank including reserve. Not vigilantly hypermiling, but try to take advantage of traffic. Regular distance including commute is over 600 miles.
If I find a convenient truck to safely draft the mpg can shoot above 100 mpg for some distance.

I can't post direct link,but make a Google search by words:'' original-test-audi-80-rekordfahrt''. Auto,Motor und Sport magazine make test and result is 3255 kilometers.
