Southern Europe is CNG friendly and I think Italy leads on numbers.

At least Europe-wide, Italy seems to be leading this field. Well, Italian-made CNG conversion kits are still usually reported to be the best ones.

Where I work the bio gas division costs almost nothing to operate and saves around $1,000 worth of gas per day.
That sounds pretty efficient to me.

Due to the high cost of natural gas setup I just waited and went electric.
But I wouldn't mind a large selection of junk yard CNG left overs, that way I could use CNG instead of propane for back up home heating.

I suspect you have High-energy H-Gas ?



I get less than that on Low-energy L-Gas ...



Lupo 3L wheels ....
I have long wanted to do that

I wouldn't get the 145 tyres approved on the car though
Not sure about the wheels themselves either


How did it alter the gas consumption ?
Handling on 145s ?

They mix both blends on the grid atleast on the biggest manufacturer grid and my local station is closest to the local biofactory so I dont know the grade. I think even the biostuff is high pressure low CO2 stuff.

I think the axle weight is good for those 145/80 tires but I still have my stock Up wheels with michelin energys if neeed be. It was not big jump maybe 100grams on the lighter narrower wheels but winter setup should gain more. Hadling is fine on both tires with about 3.5bar pressure.

Has to be H-gas with your consumption
It's rather hard work to get the up! below 3 kg on L-gas

Anyway, if it's biogas, you're doing very well
Outside of Belgium -we don't have biogas here- I try to tank biogas whenever I can

For the periodic technical test , likely

Slight lowering would be nice but its not economical enough overrall.

BTW, you're not allowed to lower a CNG up! due to R110 regulation
(height of CNG tank above the ground)
The eco up! has VW's Blue Motion Technology, which on a regular petrol up! means it gets lowered a bit, but not so on the CNG version

Maybe a Pan under the engine as it does not show out if it looks horrible.

You could install an airdam and lower the pan behind that a bit, rather than lowering the whole car

The problem with the up CNG is that it consumes so little that there isn't very much to be gained.
Mods are never going to pay for themselves

I think all gasum stations sell H-gas.

I will try MOT with the luposetup and if it goes well sell the energys.

Good call on the lowering!

Hopefully next summer I get some motivation to tinker with aero. I might try wai in the mean time. Have you tested it with your eco up?

Welcome nice rig and spec sheet.

No, it already draws its air close to the engine, with the engine layout leaving little room to route it anywhere else




For the uninitiated:
The red circle is the natural gas injection system.
To the left of the air intake trumpet is the CNG pressure regulator/coolant heat exchanger that warms up the expanded, and thus chilled, natural gas
(expands from ~ 200 atm to ~ 7 atm)

After years of making it go faster and handle better I am now looking to make it get better gas milage. The engine has many performance upgrades including an APR multi program ECU. Many of the hardware upgrades allow the engine to achieve better gas mileage when the lead foot is removed from the equation :-). Current plans are to add a custom high milage ECU program to maximize gas consumption. Will also be looking at low rolling resistant tires and narrower rim replacements. Current gas milage ranges between 25 city and 35 highway. Hoping to raise that to 35 and 45 mpg. There are also carbon fiber hood and fender replacements to reduce weight.
