Cadillac is developing a new battery-electric car and ultra-luxury sedan as part of the brand's reboot that should be released by 2020, the brand's new head confirmed in an interview with Reuters.

Johan de Nysschen, a former Audi and Infiniti executive named to lead Cadillac in August, plans to expand the brand's lineup from five to 10 vehicles in the next six years, he told the outlet. He is also moving Cadillac's operational headquarters to New York.

One of the new vehicles will be a top-end luxury sedan called the CT8 or CT9. It will compete with long-wheelbase versions of the BMW 7-Series and Mercedes-Benz S-Class. He also plans to introduce a plug-in hybrid version of the new CT6 sedan heading into production at the end of 2015.

Additionally, de Nysschen is planning to develop a battery-electric car that would likely replace the slow-selling ELR.
