Battery charge rates are properly compared in C-rate terms. And from where I sit there is nothing special about the S. The volt has fancy schamncy cooling, the fisker did as well (though they haven't yet mastered how to use a hose clamp ).

What is coming out of the wall has nothing to do with the car 20, 30, 40, 50, 80 amps etc... The vehicle designers can choose to accommodate different charging standards. DC fast charging has no purpose for a PHEV, but the new GM EV supports DC fast charging. It only takes 20minutes and is using the new SAE standards. I am completely unimpressed with proprietary charging standards which are destined to fail. It is silly that they can't sign onto the same standard as others since the charge points installed are therefore less useful. I know this stuff is early, but I certainly hope Tesla in the future will work with standards organizations to try and get future vehicles to be more compatible with a wider array of DC fast charging infrastructure.
The volt charges its 16 kWh from a 240 v outlet in 3 hours. The base model S charges 40 kWh pack in 4 hrs from a 240v outlet. The car definitely has an effect on the current coming out of the wall as the loads will be different for different chargers and charge rates.

I'm not saying the S is drastically more advanced just that it does charge faster. I'd say the crash test record shows the battery safety systems in the S are better as well . Not trying to take anything away from the volt it obviously has its pluses. Same with the karma.

I agree about the proprietary charging thing. For Tesla to be successful in the future they need to get on board and help push the standards forward.
