With hours to go until the Tesla Model Y is given its formal debut, the electric car maker has teased its second crossover on Twitter.

The video posted on the social media network shows the Model Y under a car cover, revealing the car's silhouette.

Just like the bigger Model X, the new crossover will have a steeply raked rear, meaning it shares more in common with a BMW X4 than a Toyota Kluger.

Unlike the Model X, the more affordable Model Y will not be equipped with Falcon Wing doors. It is expected to share many design cues with the Model 3 sedan, though.

Two weeks ago Elon Musk, Tesla's CEO, revealed the Model Y will be roughly 10 per cent larger than the Model 3, and will be priced accordingly.

According to the company's latest shareholder letter, the Model Y is expected to "achieve volume production by the end of 2020, most likely at Gigafactory 1".

Gigafactory 1 is Tesla's plant in Reno, Nevada, where the company currently produces battery packs in conjunction with Panasonic.

The Model Y will be unveiled today at a live-streamed event scheduled for 8pm Pacific Daylight Time (2pm Australian Eastern Daylight Time) at the company's design studios in Los Angeles.

It should be noted Elon Musk has a habit of turning up late - exceptionally late, sometimes - to these sort of events, so budget for that if you're planning on tuning in.
