The most expensive Cadillac ever will be on display at the Detroit auto show on Friday.

The show car version of the Cadillac Celestiq is expected to cost $300,000 or more when it goes into production later in the century. The vehicle is called an all-electric flagship sedan.

It marks a pivot for Cadillac into hand-built vehicles, which are typically reserved for high-end sports cars and ultra-luxury vehicles. By the end of the decade, Cadillac wants to offer EV's.

Technical details about the Celestiq were not released by GM.

The vehicle will feature five interactive displays, including a 55 inchdiagonal screen across the front cabin of the car, a smart glass roof, and Ultra Cruise, GM's next- generation advanced driver-assist system.

The technologies will be part of the production car. CNBC confirmed through a person familiar with the plans that the price and production of the Celestiq will be reported by The Wall Street Journal.

A show car is used to show off a new car. A concept car is a preview of the design direction of a car that may or may not be produced. The electric Lyriq SUV went into production and was launched by Cadillac.

Designers drew inspiration from well-known cars such as the V-16 powered "coaches" of the era before World War II, and the hand-built 1957 Eldorado Brougham.

The vehicles were the epitome of luxury in their respective eras and helped make Cadillac the standard of the world. The configuration of the show car, which is also a sedan, offers the very best luxury experience, which is what they expressed.

The upcoming Cadillac Celestiq will be built at GM's tech center. It is the first time that a vehicle will be produced for commercial sales at the tech campus.
