Electric vehicle startup Faraday Future has shared an insight into the development of the FF91, its upcoming competitor to the Tesla Model S and Lucid Air.

The video is designed to highlight the collaboration between Faraday Future's design and aerodynamics teams, as they work to keep the coefficient of drag below 0.26.

According to the teaser, the roof spoiler on the FF91 has been guided by the need to maximise interior space, as an example of form following function.

It also highlights the way computational fluid dynamics is helping hone the shape, which is said to create 10 per cent less drag than comparable cars at highway speeds, for a 5 per cent range improvement.

Obviously, Faraday Future isn't the only company to pour huge amounts of time, money and effort into honing the shape of their cars, but it's an interesting peek nonetheless.

It also comes at an interesting time for the company, as investor Jia Yueting is ordered back to China to deal with his mounting financial problems.

Yueting has been ordered to return to China by December 31, after it was revealed LeEco (which he founded) was burning money in search of rapid expansion.

He has strong ties to Faraday Future, and reportedly owes around $92 million – although that figure varies, depending on who you ask.

According to the China Securities Regulatory Commission, his unwillingness to tackle his mounting debt is a "serious infringement" of shareholder rights.

The commission doesn't know where he is, and has him listed on a blacklist designed to stop those in heavy debt from travelling.
