VW Lupo 3L --> 2L

[Arragonis]

Slightly OT question - would DRLs style lights (LEDs ?) work as a replacement for dipped headlights and use less power ? I'm thinking more for being seen in bad weather rather than illuminating the road ahead.

Why don't you get in touch with Nokian, and ask to do some real-life testing of their upcoming eco-tyres that they claim will have greatly reduced RR ?

Sure.
LED headlights are coming to production cars - a (very) few already have them.

But you can't just use DRL-sets as dipped beams.
It's downright illegal.

That's excellent mileage you got there !

But from my experiences, that's about the best you can realistically do, or for that matter, will ever see any bog-standard non-hybrid car capable of.

I don't think Vekke's Lupo will remain unmodified much longer

Does it have ABS ?
If not, why not run them all 4 to 1 switch instead of using 4 switches ?

Moreover, bear in mind these cars were designed over a decade ago.

Btw, your Lupo's weight you mentioned in its specs is prolly in kg and not in lbs. 830 kg = 1830 lbs.

What is your slowly? 80 km/h?
Corrected that weight.
Today made the second fillup and was able to reach 3.14 l/100km actual speeds are on the fuel log. With full P&G mode @ 86 km/h was able to reach 2.4-2.5 l/100km figures on the cars computer.

Also the start & stop system works. Also with lights on and even with radio on fan. It might depend more on the altenator load so if your battery has power it can shut down more easily.

I will have a meeting with Nokian passenger tire department later on August after summer holiday season. Because you are rigth that I need all the help to reach that 2 liter target. I have my own idea of what I would need on my Lupo and its not regular tire at all. dont know if its possibly to manufacture or not but they can propably answer my questions. First I need to get to proper range with the gears before they can help me more.

I think I have ABS as a standard.

On average 90 km/h, but obviously, p&g'ing, in practice that's anywhere between 75 km/h (uphill) and 125 km/h (downhill).
From the last traffic jam in the Avignon region on, we drove over 1100 km non-stop in about 13 hours, including a handful of stops to switch drivers and 1 fill-up.

Would you mind egging on the good folks at Nokian to produce their top-notch LRR tyre in the 145/80 R14 size my A2 3L needs? All marketing aside, the abovementioned Youtube movie showed impressive results on their experimental new type of LRR tyre.
Bridgestone's B381 Ecopia, designed (over a decade ago) especially for the Lupo and the A2 3L, are the only tyres in this size category, and they're becoming increasingly hard to find. And I'd genuinely hate to shoe my A2 with anything worse, i.e. wider than 145/80 R14 ... "Less drag = Less fuel", as someone said

[Vekke]

That is some nice avg speed. For refence I appreciate all fuel logs which have even some data of what have happened during fillups . It is much easier to estimate how other cars is running if you have even some data of the speeds driven and other mods made etc.

When you P&G does your engine sometimes rev up before the clutch bites in? I have this kind of problems if I am on the throttle when I put the gear in :/.

I also today hunted those 145/80R14 tires with no luck. Also those 155/80R14 Toyo tires are under rock. I finded only Nangkang on that size and that is a no go even for a test. I will propably see shortly guys from Nokia at Power truck show:
Power Truck Show - Galleria which is a trade show and truck show. Tires that I will need for my Lupo 3L will also fit your car for sure .

Today the cars inspection was a clear pass and the modding can really begin. Today installed smooth tinted polycarbonate TuneCovers:
Less drag = Less fuel | Aluminium wheel hubcaps | Eco Tuning --> Tuneko Ltd

Wheel Machine 2000 - Felgen Tuning und Reifen has 20 Bridgestones B381 on stock in that size.
61 euro apiece.

It's a sign of the times that even the more recent eco-tyres - Conti EcoContact 3 , Michelin Energy Saver, ... - aren't made in that size.
