CVT and Fuel Consumption

[Kev1nDonn]

I was thinking the same. Maybe the Sat Nav knows some fantastic short cuts.

Oops. Stupid keyboard doesn't like double taps. 1000 miles. Doh.

In response to the original message here about the box being in 5th when you change to manual, I tried this today and found that as you select manual the revs rise and you are in 5th but if you change up to 7th and go back to auto then the revs remain constant. My deduction is therefore that the box is in auto 7th but changing to manual drops it 2 ratios.

Refence first postHi have just returned from a 2 month 7000+km tour of Europe, England and Scotland.my 10 week old 1.6 cvt Tekna is showing an average 5.8lt/100kmthere is 8456km on the clock, well please with the car and fuel consumption

Yes, except that the car lies about its consumption -- as nearly all do. I have an app where I put the actual fuel consumption -- from full tank to full tank and measure the kilometres I did in between. My Nissan Qashqai 1.6 CVT constantly underestimates the consumption by 0.5 litres! Still, could be worse. Lexus, for instance, (from my experience) is even more imprecise in this regard.

I think that 0,5 litres is not an acceptable amount of inaccuracy. It is a clear fault that should be fixed.I've had so far only one full tank to full tank and I got 6,2 l/100 km while the car showed 5,3. That means that about 9 liters of diesel have leaked out of the tank without going through the fuel injection system. Another option is that there is a bug in the software calculating the consumption incorrectly, about 14% less than reality.This must be an error in the software (or a leak in the tank), as there is no reason for deliberately programming the trip computer to show heavily underestimated values. This will not increase sales or customer satisfaction, it only annoys users and renders the whole system useless.

Common, this is nothing unusual and European car manufacturers were cheating this way for years just to show better fuel consumption to their customers. In EE this is not controlled / forbiden like in US, they know it and use it.
None of the cars I owned was accurate. New Qashqai shows about 0,5l fuel consumption less, old Qashqai showed 0,7l difference. The best results had US company car Chevrolet Impala which showed only 0,2l diference. Ask yourself a question, why Nissan did not program it to show worse fuel consumption results?
So it's not fuel leaking, it's manufacturer's cheating! duncho2014-09-29 08:06:38

what is the name of the app please steve

[duncho]

If you mean smartphone app for keeping fueling record and real consumption calculation, I use "Gas Cubby" for iPhone.

I doubt anyone would be able to come up with a 'better' system, we all seem to drive differently so an artificial system no matter how flawed has to be better, just a pity they can't all be wrong by an equal amount which would at least make the comparison between cars valid. If only to make the point our guy from Kirkcaldy seems to regularly beat the official figures whereas others, myself included, struggle to hit 40mpg. Much better than my BMW 330d that's for sure!
