Tesla Motors sent an email Monday morning to all Roadster owners to confirm the expansion of its battery upgrade program to now include early models, which were excluded until recently. Earlier this summer, Tesla released the details of its long-awaited battery upgrade for its first vehicle, but a lot of owners were disappointed to learn that it was only available to later versions of the all-electric sport car.

Now every owner with $29,000 to spare gets access to the upgrade which increases the range of the vehicle by about 35%. The full email from Tesla:roadster 3.0
