Well even the big limousines are actually quite fuel-efficient these days. For example, the series 7 BMW 730 with its 250 horse powers uses only 5.6 l / 100 km

Well even the big limousines are actually quite fuel-efficient these days. For example, the series 7 BMW 730 with its 250 horse powers uses only 5.6 l / 100 km (http://www.bmw.com/com/de/newvehicles/7series/sedan/2012/showroom/technical-data/? http://www.bmw.com/com/de/newvehicles/7series/sedan/2012/sho...).
BTW coal makes up for only 20 % of the electricity production in Germany, and most of the coal-based power plants are quite "clean" in the sense that they make good use of the available energy (in most cases the heat waste is used industrially and emissions are heavily filtered).
As I said before, adoption here is mostly a question of availability, cost and efficiency, all three of which need to be improved before customers will see electric cars as a "reasonable" choice.

These are unrealistic industry-produced numbers. This is widely discussed in Germany that these numbers are a joke. Also forget the massive amount of energy going into the production of these cars and the materials they use. The huge space and infrastructure they are using... we still have air problems in the cities because of the diesel cars. > 20 % of the electricity production in Germany Coal has a share of 43.6% of electricity production in Germany. > in most cases the heat waste is used industrially and emissions are heavily filtered). The filter ash is going where? The coal is coming from where? CO2 is not filtered.
- sgt 11y agoI agree, the numbers tend to go towards 10L/100km for these cars, based on typical driving habits.
