As far as teases go, this is pretty good.

Tesla CEO Elon Musk sent out an intriguing tweet Wednesday night.

The tweet included what looks like a promotional graphic of a garage door partially raised and the front end of a car showing.



"About time to unveil the D and something else," Musk wrote.

That image is right above the date October 9, 2014 clearly suggesting we'll see what's behind the door next week.

So what is the "D" and what else might Musk unveil?



There's been plenty of speculation about when Tesla will unveil its Model 3, next generation car.
