Cost of Electric cars sees future in the price of the Tesla S, soon to be released. Tesla adds the price of a replacement battery 4 year, 50,000 mile warranty to the overall tag on the car. With a jump of $2,500 it may seem as though its taking a significant leap from its original cost, but in comparison, the S is priced competitively. Inflation has been fairly consistent at 8.75% which would indicate that the Tesla should have an increase of $5,000 from the announcement of $57,400 in 2009. The jump of $5,000 would have turned heads, yet made sense. They also offer an additional warranty for another 4 years and 50,000 miles. How do they afford to offer such a deal? Predictions for the price of batteries seems to be promising. They range from $8,000 for the 40-kWh battery, $10,000 for the 60-kWh to $12,000 for the 85-kWh pack. Only the future will show how these prices remain, but with the push for more efficiency through technology continues to lead the way in the rechargeable market. The more attractive the cars and the more economical the choice seems to be, the more everyone will be able to get involved with the lowering of our emissions and harming our environment less.
