Comparisons to the Batmobile exiting the Batcave are inevitable, though don't expect a DC tie-in with whatever the D ends up being. A more likely scenario is that Tesla is getting ready to introduce the Model D, which would fall in line with the company's past naming schemes. There's already the Model S, an electric sedan that you can buy today, and Model X, which Tesla will launch sometime in the future.

Perhaps the D is referring to all-wheel drive, a feature that Jaguar only added to its luxury cars a few years ago to boost sales in snow laden areas. Or perhaps something else. Either way, a follow-up Twitter post only fueled additional speculation.
Tesla Model X
"I love the Internet. Comments had me literally ROFL. No, it wasn't intentional. Glad I didn't mention the other letter!," Musk tweeted.
Maybe the other letter is "M," in which case Tesla could be getting ready to unveil a dual-motor" feature, which Musk has already made a reference to in regards to the forthcoming Model X.
