Newly manufactured Tesla vehicles are placed on transport trailers from a large inventory of newly made vehicles in Burbank, California, August 24, 2018.

Tesla CEO Elon Musk said Tuesday the company will eliminate some interior design options for the Model S sedan and Model X sport utility vehicle to simplify production at Tesla's assembly factory.

The Model X is the company's most complex vehicle in production today, in part because it has unusual falcon wing doors. Customers have had the option to configure the interior of Model X with six or seven seats and a number of options for upholstery, wood and headliner materials.

Musk, who announced the news over Twitter, said some options won't be available after Nov. 1. "Order now to be sure of the one you want," he said.
