One computer wiz claims to have hacked into Tesla's firmware and discovered a reference to a juicier battery. Self-proclaimed white hat hacker, Jason Hughes, says he discovered a secret in Tesla's firmware 7.1, but he didn't want to tell the world outright what he discovered, so he made Tesla Motors Club forum-members work for it by obfuscating the secret with a hash. TheSHA256 hash, a one-way function, would either require forum members to guess and check to decrypt this code, or to look it up in a hash directory. Forum member LuckyLuke decrypted Hughes' hash and discovered its meaning: P100D. P100D is the nickname given to Tesla's upcoming 100-kWh battery pack that would give the Model S a range of 300 miles or more. In response to a fellow forum-member decrypting his secret code, Hughes responded on Twitter. On the forum, Hughes had some additional information to mention, saying: There have been references to the P100D in firmwares as early as 2 months ago. They finally added the badges to 2.13.77. I mucked it up a bit by adding a crappy background (it's a PNG with transparency in the firmware)... There are quite a few things that are in the firmware that I'm not prepared to share publicly. Just like the P100D has been in there for months with my lips mostly sealed. I don't want to spoil all of Tesla's surprises.
