As with gasoline fueled vehicles they will improve with time.


Even todays best EVs with state of the art technology including battery, composite and energy management electronic control and electrical motor design technology can barely exceed the performance of a Model T Ford. A Model T-Ford has greater range than the Nissan Leaf, doesn't take 22hrs to refuel (to get 65-70 miles capability) and yet the Model T-Ford still has a typical fuel consumption rivaling contemporary vehicles sold today (@20 mpg). Basically the Nissan Leaf EV is as good as it gets and will be as good as it gets for the next 50 years. You can't simply get around the fundamental laws of energy physics with more elegant refined design or materials selection simply because todays EV manufacturers are already approaching these limits especially when a production vehicle is required which is available at an acceptable cost. Even with the Nissan Leaf battery there is disbelief by many observers at the quoted cost for the Lithium Titanate battery, with many questioning whether a loss leader has been implemented so that Nissan is at the forefront of commercial EV sales.

BTW there have been 100mpg internal combustion capable vehicles designed such as the experiment British Leyland ECV3 car way back in the 1980s.

The existing coal, oil and natural gas power plants will work quite well.


No they don't, to replace the energy requirements provided by the liquid fuels to power todays vehicles in the USA would require another 2 or 3 duplicate electrical power supply grid generation systems currently installed in the USA. The idea that everyone plugging in their EV overnight will take up the current grid electricity generation slack in generation capacity is incorrect.

Edison and Ford were probably having the same debate 100 years ago. wink
