Tesla CEO Elon Musk is expected to make an announcement Thursday night that should clear up a week of speculation that put "the D" in dramatic and a bump in the electric carmaker's stock price.
The electric car manufacturer appears poised to unveil a new model after Musk's tweet last week that indicated plans to "unveil the D and something else." The tweet featured a graphic with Thursday's date and a partially opened garage door that masked all but the menacing front end of a vehicle with Tesla's logo and signature headlights.
In the days after Musk's mysterious tweet, Tesla's stock price climbed about 6 percent. The stock took a slight dip Wednesday before rising again Thursday ahead of the announcement.
Tesla is likely adding another member to its family of vehicles, which includes the Model S luxury sedan. The company has plans for a Model X SUV and mass-market model called the Model 3.
Thursday's announcement might involve an all-wheel drive vehicle, which would fit nicely into the carmaker's lineup and allow Tesla to match offerings from similarly priced competitors. Electric vehicles allow engineers more flexibility than a traditional front-, rear- or mid-engine vehicle when it comes to how power is distributed to each wheel. For example, instead of transferring power from one engine to four wheels, an electric powertrain might use two electric motors for the front and back wheels or even four electric motors dedicated to each wheel.
But the guesses don't stop there.
A Tesla with greater range or higher level of driver assistance technology, such as lane assist or collision-avoidance braking, are some of the possibilities.
A self-driving vehicle or something that's not a car at all have all been mentioned in response to last week's tweet.
