Fresh Canadian data
UltArc - thanks for sending me your spreadsheet!
I revised it with fresh Canadian figures, and my results were a little bit different. My starting points/assumptions:
- I used only the four least expensive vehicles in Canada, base trim, manual transmission... plus Prius C for comparison to something extra efficient.
- I looked up each total vehicle price including all taxes, fees, etc.
- Assumed a 10 year average gas price of $1.40/litre (probably conservative)
- Assumed 20,000 km per year
- Used the more realistic U.S. EPA "combined" ratings for fuel economy (using 7.8 L/100 km for the Micra, our current estimate -- same as the Versa sedan)
- Estimated Micra's freight/delivery/dealer fees based on the Chevy Spark's.
Anyone can look at the spreadsheet here: https://docs.google.com/spreadsheet/...FE&usp=sharing
With these assumptions, the base Micra holds the lead until year 8/9 (or 160,000 km / 100k miles), when the Mirage edges into the lead...
Of course, if you drive half as much, the Micra stays in the top spot twice as long. But if fuel prices average more than 1.40 a litre, things change again. We'll have a better idea when we get more info from Nissan.
Using the same starting points, the automatic Mirage takes the lead in year 3. (It's in the Google spreadsheet.)
But the truth is, the results are so sensitive to small changes in the starting assusmptions, we really need to wait for the hard numbers from Nissan to button this down. EG. If the Micra's combined rating is 7.4 instead of 7.8 L/100 km, it retains the lead right up to the end of year 10 (200k kms / 120k mi.) instead of year 8.
