- The car fits seven people and their      luggage: five adults and two children in rear-facing seats under the hatch      inside, with luggage in the boot up front.
 - If not people, it can fit a mountain bike with      its wheels still on, a surfboard and a 50-inch television at the same      time.
 - The dashboard screens were installed to rid the      interior of buttons. The 17-inch main display is fully 3G and Internet      capable.
 - The 300-mile range is possible (vs the Roadster's      244-mile range) because the S has 8,000 battery cells vs. 6,000 in the      Roadster, the batteries have been improved in mass and volumetric      performance, and there is more advanced cell chemistry in each cell, and      the S has a cd of about .27 vs. the Roadster's drag coefficient of .35.
 - On a 220V outlet, the car can be recharged in 4      hours.
 - Option packages are being decided, with the only      initial option being the battery pack. Customers will also be able to buy      the 160-mile pack and rent the long range pack for a trip.
 - They are finalizing the warranty, and expect it      to be 3-4 years for the car and 7-10 years for the battery pack. They      expect replacement battery packs to come in at "well under      $5000" according to Elon.
 - The quickness: the standard S will get to 60 in      5.5 to 6.0 seconds. A coming sport version will get to 60 in "well      under five seconds," Musk says.
 - The car will get a single-speed transmission.
 - The body panels and chassis will be primarily      aluminum, with a total weight of just over 4,000 pounds, about 1,200      pounds of that being battery mass.
 - For infrastructure, Tesla is working with a      government-affiliated partner to set up battery changing stations at      various locations. They will be able to change the battery in 5-8 minutes,      "quicker than filling up your car with gas."
 
According to Tesla's numbers, buying a Tesla S will save you $10-$15K vs a comparably priced gas-powered sedan when gas is $4 per gallon. For an equivalent comparison, you'd have to lease a $35,000 gas-powered car. The biggest hitch: the car doesn't go into production until Q3 of 2011.
