Hey Bataleon,

I ONLY coast in neutral. Because I mostly travel highway and most of the time in near peak-time traffic, losing brake-pressure is not an option for me either. I can live with the likely 0.6-0.8L/h burn rate. The Bantam's Odo is electronic, so I don't know how it'll cope with a kill-switch. No EOC for me. It's the 1.3i.

Be that as it may, I've been averaging 6.24L/100 since bought and completed 2014 with an average of 5.98L/100. My record down from Pta to Pmb is 5.2L. I run my tire pressures at 2.4 Bar and up to 3.0 (the limit) on longer trips, as keeping it at 3.0 on this already stiffly sprung vehicle is a bit harsh.

I don't travel particularly slowly, mostly driving between 100-110km/h, but you can score A LOT with coasting when you can. Also note my lower grille block, which is fine even in the hottest weather, as it doesn't really block the radiator, just the extra.

Not shown in the picture is a solid tonneau cover. Good luck with your ecomod adventure.

I finally did a grill block on my fiesta I still need to do a thread about it. mirrors are also folded back. it surprized me with a .3 to .5L / 100km improvement. I was not expecting so much as the hilly terrain limits the advantages of aero mods. definitely going to improve airflow under the car belly pan is next

Thumbs up

SvdM, thanks for the interesting post. 6.24l/100km is pretty decent considering you mainly travel during peak hour traffic.

I've recently been keeping my Polo's tyres at 3 bar which is good for the open road but rattles around town.

I found that pulse-and-glide helps a lot, even when travelling at highway speeds. I accelerate to 110km/h then coast in neutral down to 90km/h, then accelerate again etc. I drove 400 km on Wednesday using this technique around 50% of the time and averaged a 5.8l/100km (with a fully loaded car).

I also covered the top grill with clear tape which has reduced drag slightly.

AndrzejM, I recently opened up my Polo's drum brakes and it seems like one of the shoes is rubbing slightly. I cleaned inside them as best I could (without stripping them down) but there still seems to be rubbing.

I looked for a shoe adjuster but they're automatic in the Polo 9n3 (mk4). Do you think replacing all the springs might help?

Here are two videos so you get an idea what I'm talking about.

3 bar is the max sidewall pressure. What have you got yours pumped to?
