Do you have a link to the video? Big difference in engine setup, that Golf will have a 1.9 or 2.0L 4 cylinder which can't compete with a 1.2 3 cylinder.

Is this the guy? I failed to find the 80 mpg Golf across the USA on YouTube or Google. Help my stupid!

Probably not because it isn't a heavily modded Golf. Nevertheless, it is a great achievement.
Although, such distance records depend on the size of the fuel tank. Mine has a 'handicap' with less than 12 gallons ...

When I began my fuel saving adventure, I posted this thread mistakenly under 'Success Stories' - sorry, I was new here - but it seems that it is turning out quite well. In the meantime I cracked the code to get my car below 3l/100km, as I did a roundtrip yesterday with an endresult of 81.1 MPG or 2.9l/100. To me, it is a greater achievement than the previous one-way trip @ 84 MPG. Because this was a tour, starting and ending at the same place. And also because the average speed was a bit higher.
Result: 81.1 MPG or 2.9L/100km
Distance: 73 miles
Average speed: 49 MPH
Weather: sunny 24°C, 5 MPH wind from different directions
Road profile: 90% highway, slightly hilly
As a bonus I filled the tank and found out it was the best one ever. See my fuel log to follow it up.

It is fine. But you can always DM the mods, such as MetroMPG or Daox (I think) and ask to move your thread to maybe "ecomodding central."

you sure did! You got the hypermiling game down solid. Cold weather will bring it down again, but still... higher numbers than usual in the winter seem certain.

Probably, but there are still improvements made/to come before the winter.
First of all, the 'winter grill' will heat up the engine quicker.
Secondly, I will put the car in the garage when it is getting cold again. I think there is a lot to be gained there. To heat up an engine from freezing temperatures or from room temperature should mean a big difference in fuel consumption?
Thirdly, the new lighter wheels and taller tires will make their appearance on the car in a few months.
Fourthly, I am currently looking into lowering the car ...
Baseline, the car simply needs adjustments to further reduce consumption. But that's why I'm hanging out on this website!

That will all likely produce better winter numbers. Parking in the garage will help a little with warm up time, but probably only marginally with fuel economy. The temperature difference is significant but not huge. A block heater would help more. Somebody on EM tested block heaters' effects on warm-up and FE, I think--maybe MetroMPG.

My first thought is then: instead of using less fuel, you have to use electric power instead.
But I will be looking into this matter. |

Electrical power is often cheaper and greener than gas/diesel, depending on your local rates and energy generation mix. just something to consider.

Green, if the name of the game is improving mpg then why not use block heaters, cabin space heaters and all the tricks? There may also be less engine wear and certainly easier starting on our diesels. Generally, internal combustion engines create the most pollutants when cold. FWIW, I sometimes use two heaters on the engine and one in the cabin and do not even notice a difference on my electric bill.
Great mpg numbers on your trip.
