Have we moved forward? The new RAV4 is reported to have a 37 kWh pack for similar range. Model S pack costs seem to be $500 / kWh. (Perhaps they should put the current car on a diet and wait 2 years for the NIMH patent.) That works out at 64% over the
equivalent gas model.
Nevertheless in 1999 the price of gas was
$1/gallon. Now it's what? $4? US inflation since 1999 was
35.8% but gas went up nearly ten times that...
So taking
average mileage, in 1999 it would have taken 14.7 years' worth of gas to match the cost of the battery. That was too much to swallow. In 2011 dollars it would take 8 years' worth of gas to reach the premium for battery in the new model. If they were selling the old model today it would be 4 years.
It doesn't seem too much of a stretch to imagine that a finance model could be offered to flatten out the upfront cost. They could even take the ten year view and make a profit. Perhaps Toyota's accountants need to work on that. Renault's are.
