On Tuesday (07.01.20), the firm's CEO unveiled the new facility and the first 10 customers received the first China-made Model 3 sedans.
Musk shared his joy at being able to deliver cars in just 357 days - a record for automakers in China - by sharing a video of himself on stage, which he titled 'NSFW' (Not Suitable For Work), in which he could be seen throwing his jacket and unveiling a t-shirt with a cartoon of the factory on a t-shirt.
He wrote alongside the Twitter clip: "At Tesla Giga Shanghai NSFW!! (sic)"
He also claimed that "ultimately Tesla Model Y will have more demand than probably all the other cars of Tesla combined."
No other details about Model Y were revealed.
Meanwhile, Musk recently ruled out a road bike for Tesla after a near-fatal accident he was involved in aged 17.
The billionaire businessman was asked when we can expect the electric ATV quad bike, which he said will be available at the same time as the Cybertruck, and admitted it would be "cool" to create an electric dirt bike, though he was adamant that he will never make a road bike, because he "almost died" on one when he was a teenager.
Responding to a Twitter user who asked when the ATV will be released, Elon replied: "We'll aim to have it come out same time as truck. Two seater electric ATV designed to work with Cybertruck will be fun! Electric dirt bikes would be cool too. We won't do road bikes, as too dangerous. I was hit by a truck & almost died on one when I was 17."
The Cybertruck is expected to arrive in 2021 or 2022.
