Cadillac already announced that it will offer a top-end car called CT6, which will be built in late 2015 at GM’s Detroit-Hamtramck assembly plant. During a conference last week, GM’s global product chief Mark Reuss confirmed the fact that Cadillac will offer a plug-in hybrid version of the CT6, which will return a fuel economy of at least 70 mpg.
In addition, Reuss said that the CT6 will use a 3.6-liter twin-turbo V6 petrol engine that will deliver around 400 hp. This model will use an 8-speed automatic transmission, the one offered also on the 2015 Corvette Stingray, as well as a stop-start system.
The lightweight structure of the upcoming CT6 will also help improve fuel economy and according to Reuss, the new car will be 8 inches longer than the current CTS but 53 pounds lighter.
The body structure of the CT6 will be the world’s most advanced and will feature a mix of aluminum, high-strength steel and other lightweight materials. When it will hit the dealerships, the Cadillac CT6 will take on vehicles such as the Audi A8, BMW 7-Series and the Mercedes-Benz S-Class.
