The author should do more research rather than just blindly copying Tesla ad copy: Tesla's batteries are not the most efficient in the industry. The LEAF is rated at 140 wh/kg [1]. Nissan makes their own batteries. The mid-grade Model S battery is only 120 wh/kg.

Energy density and efficiency are two different things. Tesla batteries are actively cooled/managed, allowing for moving current in and out of them faster, while Nissan's batteries are air cooled (preventing faster charges/discharges).

  I think you're talking about power density.

"The author should do more research" Add: Fawning. This is an article whose intent is to polarize the community of haters and likers by comparing it to Apple. There is really no comparison. The Tesla isn't a better "car" in the sense of how it gets you between a and b than the existing vehicles out there which are mature products that have been improved over time in the features and benefits that people care about. With Tesla you have to worry about distance, batteries, the high cost - I mean who cares if it accelerates as quickly as it does and who cares that there is no noise? The potential market for products in the price category that computers are in is much different from cars. Most people don't buy multiple cars and replacing one is a big decision to make. It's not like adding an ipod and an ipad. Bottom line is what do I get by buying an Electric car exactly even assuming it is the same price as the gas vehicle? How important is the gas savings when you weigh that over the lack of utility in other areas? I mean get real. Stuff like this will be a non-starter to most people: "which will give you 150 miles of power in a 30-minute charge" How many people are going to want to deal with that? People buy cars on emotion not rationality. It's the same reason someone wants 4 wheel drive even though they might only need it a few days per year.

  I think you answer your own question here: "Bottom line is what do I get by buying an Electric car exactly even assuming it is the same price as the gas vehicle?

    People who pay $90k for a car to commute back and forth from work every day don't care about saving money on gas. It's just a status symbol like any other luxury car. But I hope it takes off, because it will finance the expansion of Tesla into cheaper cars.

Depending on the circumstances though, those couple days you need it might be absolutely crucial. It's very easy to think you'll need 4WD when you never will, and many people do, but frequency of use is only part of the equation.

  There's a recent Consumer Reports video on YouTube where the three people discussing the Model S all seemed to think that if they were trying to spend $90k on a car, they'd get a Model S and not something else.
