When Johan de Nysschen joined Cadillac in 2014, the luxury brand promised a massive assault on the premium market with brand-new nameplates spread over several niches. Caddy also promised new, large sedans that would compete against the most luxurious BMW and Mercedes-Benz offerings. In 2015, Cadillac launched the CT6, the company’s most luxurious and technologically advanced vehicle to date. Slotted above the XTS, the CT6 became Cadillac’s range-topping model, but GM’s premium division said it won’t stop there, looking to create an even larger sedan. It goes by the name CT8 and it will arrive in showrooms for the 2019 model year.
