In the last ten years or so, I've been interested in choosing cars that are efficient as well as fun to drive. I'm convinced that we need to do what we can to reduce our emissions of carbon dioxide. I'm convinced that the supplies of petroleum are finite and that easily accessible oil will run short in my lifetime. I'm convinced that gasoline prices will rise in the coming decade. I'm convinced that we need to rely less on foreign sources of energy for our own security and to reduce the potential for wars.
Three years ago, I looked carefully for my new car and chose to lease a BMW 328i coupe. This is one of the smallest BMWs and I chose the smaller of the two engines available in order to maximize the gas mileage. The best mileage that I ever got in the car was 34 mpg on a long freeway leg. But it gets less than 18 mpg when I drive around the suburbs. For my next car, I really wanted to get something much more efficient. I was looking to at least double my gas mileage while still getting a fun to drive car. My choices included a Mini, a small diesel Audi, or possibly a new small sport hybrid from Toyota or Honda, or an electric car if one was available by my mid January 2011 timeline.
The other reason that I'm interested in electric cars is that we make a useful amount more electric power than we use with our solar PV system. We can use that extra power to drive thousands of miles per year with no fuel costs! Electric cars can drive between three and four miles for every kilowatt hour. With our extra solar power and our reduced power usage that I spoke of in former blog posts, we should be able to drive close to 5,000 miles per year before we pay for any electricity for our home or our car. If we drive a further 5,000 miles per year, the electricity cost should be about 2.2 cents per mile, or about one third of the cost to drive our Prius.. And that's LOW cost motoring. It would be like getting 135 mpg in a Prius or like driving our Prius at its current 45 mpg for $1.00 per gallon of gas.
A small company, Tesla, has shown very clearly that electric sports cars can be exciting, fast and fun. They introduced their sports car based on a Lotus design in 2008. But that car costs over $100,000, and it is very small and impractical.
Mini brought out an experimental electric version of their Cooper called the Mini E that they used to learn about how electric cars would work in the real world. I got to drive a Mini E courtesy of a friend. What a fun drive that was! It really got me thinking about getting an electric car.
It happens that two companies were planning to release an electric car in late 2010, which met my need to find a car around the time when my BMW lease ends in January. GM will release their Volt in November and Nissan will release their Leaf in December. I decided that I would look closely at both of these cars to see if one of them was what I was looking for.
