In January, Tesla unveiled the updated version of its Model X SUV. After months of delays, Tesla finally delivered the vehicles to customers.

On Sunday, the electric-car manufacturer posted photos on Twitter of the "first deliveries" of its Model X. Customers received the first Model X outside Tesla's Fremont, California factory.

This is the most significant update Tesla has made to its largest and most expensive vehicle since it was launched in 2016. The SUV's interior has the most significant changes. The Model X, at $100,000, has a landscape-oriented screen (rather than a horizontal one), a second screen in the back for rear passengers and a rectangular steering yoke that looks like an airplane's.

The Model X received a new battery pack from Tesla and an exterior facelift. Some parts that were chrome like the window trim and door handles are now black. The front bumper is also different. Elon Musk's automaker introduced a high performance Plaid Model X. It boasts more than 1,000 horsepower and a 0-60 mph time of 2.5 seconds.

Musk, ever optimist when it came to timelines, said that deliveries of the Model S would start in February and shipments of Model X would follow shortly. The new Model S deliveries were a few months behind schedule, starting in June.

Musk stated that Tesla faced "more challenges than anticipated" when developing the Model S and Model X during its first quarter earnings call in April. This included dealing with supply chain issues and creating new internal production processes to produce the updated vehicles.
