CU2 Auto, 1000km on 1 tank

[buddah51au]

My suspicions have proven correct, it is possible to get in excess of 1000km from 1 tank of fuel. In making that comment i didn't quite achieve the magic figure, but that was totally due to the location of available service stations.

Low fuel warning light came on at 933km & i refilled after 972km. The trip computer was reading 78km till empty, but the next service station was 102 km away which I felt was too much of a risk as i don't know the accuracy of distance to empty.

For those interested the figures are 972km, 62.89 lts = 6.47L/100km. Needless to say I am more than impressed.

questions....

1.did you fill up DEAD empty (IE car would not start due to lack of fuel/fuel pressure) - there is a reserve in teh fuel tank ,. probably around 8-10 litres.
2. car is completely dead standard ? no aftermarket rims etc ?

Interesting - because the car is quite a heavy lug of a thing and you are getting perhaps better fuel economy than a PRIUS or INSIGHT.

1: the car was not empty & I wish there had of been a servo i could have filled up at between towns so that i could have passed the magic figure.

2: The car is completely stock except for a few minor cosmetic options.

I am convinced that given the right conditions :- eg the inland trip from here to Sydney i could beat that figure by some margin. I will also add that all of the 972km was done at 3 to 4 kph above the posted speed limit with cruise control on. Air Con was also used for a short period.

Buddah51au - would I be correct in guessing that the majority of the distance was country driving ? Can you estimate the percentage of

1) Flat country
2) Hills
3) City / suburban

Whatever the breakdown it is still an impressive result and shows what a standard non-hybrid car can achieve

Oh and were you using RON95 or RON98 and what tyre pressures ?

Amazing....

Some questions though:

1) How much rpm are you driving on average? below 3000?

2) Also the condition of traffic?

Im impressed that CU2 auto could go that far with 1 tank!

I will do my best on this as it is a valid point.

Country town driving - 30km
reasonably flat open highway 702km
Hilly driving, i would call it similar to the Putty road nth west of Sydney, but without slow corners, in other words quite undulating with a few serious climbs & descents - 240km

That would be as close as i could put it without speedo checking each section.

I will add that my average fuel consumption after 15300km is 7.2L/100km. I will share that spreadsheet with anyone. Just pm me your email add and I will post it to you.

its amazing what constant throttle can make to fuel economy.
for example , i have a civic with a type R engine , weight is 980kg + driver. With 98RON fuel i have got 700ks from a 32l-36l tank. (4.5-5l/100ks)

But the CU2 weighs probably 600kg more lol.

[bennjamin]

what is the quote figures for this car ?

I have got about 100ks on the red light before. I did drop back to 80km/h at the end, but still had ~2L left in the tank lol!

The quoted figure on the Euro is 8.9 i think. It is also supposed to have a 65ltr tank, if this is so i suspect there is 5 or 6 lts in the filler neck which gives a total capacity of slightly over 70 ltrs.

that pulls the highway average up to around dead 7 l / 100kms.

[buddah51au]

On 6 separate occasions i have averaged under 7L/100km, obviously today's figures of 6.47 are the best. I believe it would be possible to get the average closer to 6, or possibly a fraction lower, with flat highway running.

As a side Issue i have just gone & checked trip B on the MFD. At present it is reading 4526km - 6.6L/100km. So allowing for error with the MFD it would be around 7 as a true average over the last 4500km.
