Last week Tesla surprised the world revealing its Roadster on the same day it debuted its much-hyped electric-powered semi truck. Elon Musk claims the car is able to reach 0-60 in just 1.9 seconds. This would make it the fastest production car. It will have a 620-mile driving range.

Now Musk says the supercar may eventually possess the ability to fly. He took to Twitter Sunday first to clarify that the 0-60 time is "the base model performance" but also to tease a "special option package that takes it to the next level." The unexpected news about the Roadster has already led many observers to wonder if Tesla is spreading itself too thin and creating more financial strains at a time when it needs to focus on fixing production bottlenecks for its Model 3 sedan, its attempt at an affordable, mass-market car, and reversing mounting financial losses. This will likely only add fuel to that fire.

Elon Musk expressed uncommon skepticism about flying cars earlier this year in a TED Talk, saying they'd be noisy and generate high levels of wind force. "If something's flying over your head and there's a whole bunch of flying cars going all over the place, that is not an anxiety-reducing situation," Musk said at the time. "You're thinking, 'Did they service their hubcap, or is it going to come off and guillotine me?'" We'll have to wait for more details from Musk and his Twitter feed. Meanwhile, the Roadster will launch in 2020 with a Founder's Series model priced at $250,000 and limited to just 1,000 models.
