Cadillac Celestiq concept

 The striking new Celestiq concept is a preview of Cadillac’s first electric saloon, which will draw on the legacy of era-defining models like the Eldorado and Brougham. 

Due within the next two years, the Celestiq will be the US marque’s second electric production model after the Lyriq SUV. It will use the same Ultium platform as that car and a range of EVs from sibling brands Chevrolet and Hummer - and, soon, newly partnered Honda. 

The Ultium platform is to General Motors what MEB is to the Volkswagen Group. Modular in its conception, it houses a uniform battery charging and management system and a range of motors and inverters – with varying outputs according to model – known as Ultium Drive. 

The new Hummer EV pick-up is the first production car to use the architecture, employing a double-deck battery pack for a mammoth 212.7kWh of capacity and upwards of 300 miles of range. The Cadillac Lyriq uses just one battery, at 100kWh, but is much lighter so offers a similar range - and the eventual Celestiq production car is expected to be similar.
