Cadillac on Monday unveiled the 2023 Celestiq, an electric vehicle that is the American automaker's most expensive to date and aims to re-establish General Motors' brand as a top luxury car.

Cadillac announces its newest luxury vehicle on Twitter.

The price tag starts at more than $300,000 and ends whenever the customer runs out of ideas for custom items.

Customers can customize nearly all aspects of the vehicle's interior trim, exterior color and other non-mechanical elements. Customers can work with designers and a Cadillac concierge to customize their vehicle, and even metal parts can be made to order using Cadillac's 3D printing capabilities.

Celestiq will also roll out Ultra Cruise, a hands-free driver assistance system that can navigate on surface streets as well as highways.

The Celestiq is massive at nearly 18 feet long and 7 feet wide, and is wider and longer than a standard Cadillac Escalade SUV.

Production of the Celestiq will begin late in 2023.

Cadillac has not announced when the Celestiq will go on sale.
