The average facelift model efficiency reports here are about 9% below the pre-facelift reports. My theory on factors which contribute to this:I get that , but an almost 20% reduction in efficiency seems high
For sure, but there is also a clear correlation in the data posted here between monthly AVG speed and efficiency, so it cannot be discounted despite being individually flawed... a 12% higher speed will result in a 25% higher air resistance and energy consumption but…
…unfortunately standstill times between trips or sitting in traffic is also taken into account so actual vs displayed average speed figures can vary a lot.
Timely reminderWe are into the 22nd page of this thread now, so just a quick reminder for folk who want to contribute to this thread on what the original intent was (copying from post #1):
To contribute, you will need to reset your consumption display on the first of the month and post a pic of your Accumulated Total dash display on the last day of that month (or as soon thereafter as possible). Anyone that did a reset on 1st October can post now otherwise just remember to reset tomorrow and post at the end of Nov et seq. This will give a month by month snapshot of real consumption averaged over a variety of circumstances.
Some people post more irregular consumption updates and that is fine too - I don't want to prevent people from posting; I'm just aware that some people may not be aware of the monthly intent.
