Reported today on carscoops.com (my emphasis): "On the AWD Model S 70D, the range will increase from 240 miles (386 km) to 259 miles (417 km). Unlocking the 5 kWh will set you back for $3,250 once you have purchased the entry-level 70/70D, but order it that way from the start and you will have to pay $3,000. However, customers who bought a facelifted Model S 70/70D between April 11 and May 5 will get the extra juice free of charge. Moreover, Tesla will swap the "70" badge for a "75" one next time the car is taken in for servicing." Can't find another source for this information. Just wondering...that's not what the email Tesla sent me said.
