No, you can use 110v but it will take 10 hours to get a full charge if the battery was near dead. If you put a 220v 40amp in your garage, it speeds that rate up to 6 hours. Now if you do step up to a 220v 90 amp, you can charge in 4 hours. An the super chargers charge in less than 30 minutes in most cases. Most people drive less than 100 miles per day, and charging would take 1/3 of those times for that amount of use. I get 265 miles on a charge for abut $7.00 per charge. btw superchargers are free!. I can drive from Florida to Ohio in a gas vehicle in 18 hours using $180 of gas. The Tesla takes 22 hours and is free charging all the way. The interior will never be BMW or Audi quality, that adds weight, that means less miles on a charge. The next generation battery will probably get 400 miles on a charge. The Model X sport utility 7 passenger is coming out next this summer. The economy version is due out in 2017 with a starting price of $35k. Going 0-60 in 3 seconds make me not care what the interior looks like.
