Prius C outsells Volt, Nissan in 3 days

These numbers do not agree with data you have posted in other threads:
In this post you claimed to consume on average 308 Wh/mile from wall in EV.
So, 809 kWh (from your signature) gives 2627 EV miles, which leave only (2740 minus 2627) 113 CS mode miles!
With 6.7 gal (from signature) this gives 16.9 MPG in CS mode!
Something does not sum-up correctly here...

 

You are mixing data from different time frames

308 was my lifetime average kWh at the time of that post, which includes fair weather driving (aug - October) as well as winter.

The signature in that post was measuring from 10/29 to 2/29 (i.e. mostly winter driving as well as a few "high speed EV trips". If compute kWh form 10/29 to 2/29 I get 32.45541324kWh/100m.
Using that as you did gives 2492 EV miles, though 20 of those were "MM generated" EV miles (which does slightly deflate my kWr/100miles)
So in that 227.2 effective CS miles using 6.7 gallons or 33.93 MPG. In that time frame. (and for compete ness its was about 34.5 CS miles since then using 1.07 gallons in march -- I'll update my sig soon.

 

The time of the post was 21 March, 2012.
So, same time frame different numbers...

 

I guess you cannot, or choose not to actually read the whole post.

The post on 3/21 on 308kWh/mile clearly said lifetime average
the sig clearly has dates of 10/29 to 2/29
The today's post on MPG_CS was 4/2.. so where is there a "same time frame"

The biggest difference is that the lifetime kWh is ower, because in the summer it was better, so using the filetime kWh leads to a estimate of more EV miles. But in winter the cold temps + seat heaters (+ occasional EV heating for passengers) makes the car less efficient and so the kWh/mile was larger.
