An anonymous reader writes "Tesla on Wednesday announced that it was pushing back the release of its highly anticipated Model X until the third quarter of 2015. Explaining the delay, Tesla relayed the following in its quarterly shareholder letter: "Work continues on the finalization of Model X with the testing of Alpha prototypes and initial builds of the first Beta prototypes. Model X powertrain development is almost complete with the early introduction of Dual Motor drive on Model S. We recently decided to build in significantly more validation testing time to achieve the best Model X possible. This will also allow for a more rapid production ramp compared to Model S in 2012." During Tesla's subsequent earnings conference call, Tesla CEO Elon Musk shed a bit more light on all things Model X, including the fact that if you order one today, it won't arrive until early 2016. Forbes goes into more on the business end of what's caused delays for the company, as well as how investors should see it (critically, they say).
