VW Lupo 3L --> 2L

[Vekke]

Thanks for that info. I have that manual but havent read it with thought yet.

Reason is propably the eco mode switch, because I havent used it more than few test accelerations and newer on stanstill. Will try that also on tomorrow when I will drive it to Neste Rally Finland .

Used 175/80R14 tires were able to rotate on the Lupo 3L but bad noises come at turns from driveshafts so did only short test run and fuel consumtion meter showed 3.3 liter but road was now also damp due to rain than the previous todays test was 22 celsius and dry. Difference in diameter is 14% so if the fuel consumtion was 3.3 that makes it better even on rain and much wider tires. 3.0 l/100km --> 3.42l/100km. I think good diameter would be something like 8-10% taller tires. One good choice i Toyo 310 in 155/80R14 which I will most likely buy. First I need to test some tires with same diameter that will those make also the same noise.

What are the tyres, was there a "special" one on them from the factory ?

And are those the original 3L wheels ? I've seen those on a local Lupo petrol which a neighbour owned until the snow last winter - it was totalled by a 4x4 assuming it could stop as quick as it could go in the white stuff.

51 PSI - I may try that after my current tank on the Aygo - I'm at 40 just now (factory is 35 and sidewall is 55)

PS - photos whilst driving. Hmmm.

Anyway food was still half the price what it would have cost in Finland.

I'm sorry to hear about the 'incident' in the bakery Unfortunately, some people still think that a foreigner with German plates is über-rich and won't notice or care if someone makes some money on him I apologize for my fellow countrymen and hope that the rest of your stay in Poland was better. And yes, 1€ = 4zlotys(PLN).

Euromodder - that is a great manual I wish Peugeot put an equal amount of care into its customers' satisfaction...
I wonder how hard/easy it would be to hack the start/stop function to allow engine off coasting in certain circumstances? OR would it be easier to by-pass it than hack it.

That bakery incident was no biggie. But similar incidents happens to all tourists. First the cashier said 3€ euros and then the orher cashier or maybe the owner said that it will be 4 euros...

In germany taxi driver took 15 km longer route on my way to licence plate workshop. His Tomtom said that turn left and he went right on many junctions...

Anyway with my little electrical knowledge it would need three things to hack/bypass:
- On switch to brake pedal sensor (easy)
- No speed pulses from wheel speed sensors so 4 off switches there (medium difficulty)
- temper the brake pressure sensor to show brake pressure to computer (for me medium to hard, for electrical engineer should be piece of cake). Might need only some resistor etc...

Rest of the sensors dont need any tempering unless you dont wish to make the engine turn off more than VW has wished to be on cold etc situations...

Will it work with these mods?

I've done that "Clint Eastwood" moment when you ask the taxi driver how many places in this town have the same name. The best was the guy at Brussels airport who went along the runways and back again 2 or 3 times. He wasn't happy when challenged but the local guy from the company I wasn working with turned up just at that moment...

Congratulations on your new car. As a hypermiling enthusiast, it's impossible you won't like it a lot. If I can ever be of any help, owning the Lupo 3L's sibling, i.e. the Audi A2 3L, feel free to drop me a line. Both cars' drivetrains are as good as identical, as you may know.

As a matter of fact, I've just driven our A2 all the way to our holiday resort in southern France and back, over 2500 km / 1500 miles in all, most of which (slowly) on the highway, but also several tens of kilometers on fairly steep hills, and sacrificing fuel economy in some nasty traffic jams as well. With wife, kids (2 toddlers) and luggage, so in all weighing in an extra 200 kg / 400 lbs, I still managed a decent 2.6 l/100 km (90 MPG). Hypermiled carefully though, a Lupo or A2 3L will still do well better than 2.4 l/100 km / 100 MPG, as both my fuel logs and fellow-owners' at spritmonitor.de will tell. 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. Moreover, bear in mind these cars were designed over a decade ago.

As a side remark, most A2 and Lupo 3Ls came without power steering whatsoever. So are you quite sure yours is broken? Who needs power steering in a car weighing less than a ton anyway, right?

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

[Vekke]

VW Lupo 3L standard magnesium rim + 155/65R14 continentalecocontact3 tire weights total of about 10 kg +-0.4 kg.

For some reason scangauge II did not work on my car :/. Now I will head towards rally stages.

Good point that mine does not even propably have the power steering. Some of the later 2002 model have it. If you have the power steering start & stop system does not exist in your car. Reason why I thought it was there that last inspection had put it to faults list for some reason...

The headlights must be switched off.

At least in the Audi A2 3L's equivalent, if not identical system, this is not entirely true. I've had the engine auto-shutdown with my lights on, although obviously, much less consistently than with headlights off.
I hope Vekke won't be hampered too much by this headlight precondition, as afaik in his native Finland, having your headlights on at daytime is mandatory.

That I can confirm on the A2. Sometimes, in colder weather conditions, switching off the interior ventilator or the windscreen wiper when coming to a halt at a traffic light will make the difference between having the engine shut off and leaving it on

One way to get around that would be to install LED daytime running lights. They would also reduce electrical load. My DRLs use only 11W, instead of ~200W for headlights, position, registration plate, dashboard lights
