Cadillac’s new flagship sedan will be called the CT6, ride on the new Omega rear-wheel-drive platform and enter production at General Motors Company’s [NYSE:GM] Detroit-Hamtramck Plant late next year. Now we’ve learned that it will also be one of the lightest cars in its segment and offer a plug-in hybrid option.
The latest information was revealed by GM product development chief Mark Reuss in an interview with The Detroit News.
Reuss said that the CT6 will offer a plug-in hybrid option enabling fuel economy upwards of 70 mpg equivalent. Similar technology is already found in the Porsche Panamera and from next year will also feature in the Mercedes-Benz S-Class.
The CT6 will also offer a V-6, which Reuss confirmed would be a twin-turbocharged 3.0-liter. It will be paired with an eight-speed automatic transmission and promises to be the most powerful six-cylinder gasoline engine in its class.
Another standout area of the CT6 will be its body structure. Here, engineers have gone with a multi-material design similar to that being employed by the Germans. Cadillac’s design uses a mix of high-strength steel, aluminum and ordinary steel along with fewer parts to help shed weight. The result is that the CT6 will be around 53 pounds lighter than the CTS despite being eight inches longer. The lightest CTS tips the scales at 3,615 pounds.
One final area of innovation for the upcoming CT6 will be its rearview mirror, which Reuss says will have an integrated display that shows what the backup camera is seeing. The new Cadillac CT6 is expected to debut at the 2015 New York Auto Show next April, as a 2016 model. It will eventually adopt Cadillac’s Super Cruise semi-autonomous system and may be joined by even more upmarket models down the track like a large coupe or sports car.
