You have to rember the quotes about power and range are whan the baterys are brand new , and likely under IDEAL conditions , Wait untill the car gets 5 years old and you only get 100 miles per charge , or worse when you find out changing the batterys costs more than buying a new car .
Also most of these 'Hybrids' use a gas engine + battery power to achive that milage and range
Then theirs this whole issue
'Electric motors and batteries have improved substantially over the past one hundred years, but today's much hyped electric cars have a range that is - at best - comparable to that of their predecessors at the beginning of the 20th century. Weight, comfort, speed and performance have eaten up any real progress. We don't need better batteries, we need better cars.
