General Motors Co.’s new Cadillac CT6 will have a plug-in electric option that offers “industry-leading fuel economy upwards of 70 mpg equivalent,” plus tons of new technology, GM’s top product chief said Wednesday.

Cadillac and GM have said the top-of-the-range CT6 will be built at GM’s Detroit-Hamtramck Assembly Plant beginning late next year.

“We will create with the CT6, the world’s most advanced body structure,” Mark Reuss, GM’s, executive vice president of global product development, purchasing and supply chain, told more than 200 investors and analysts gathered at GM’s Proving Ground for the company’s Global Business Conference. “And it’s not aluminum. It’s a stronger, smarter, safer premium luxury vehicle.”

“So rather than try to copy someone, or do something that has already been done, we have created, we think the vehicle, in this timeframe, that will stand apart and make Cadillac again the standard of the world.”

The automaker said it has developed a mixed material body structure that combines use of the company’s patented welding technology with high-strength steel, aluminum and steel stampings and castings to help create a lightweight vehicle that uses 20 percent fewer parts.

For example, Reuss said GM has taken 20 different parts used on a front body pillar and created one single casting. He said the technology helps improve safety, ride and handling and the quietness of the car.

“We have eliminated a lot of opportunities for failures or quality spills,” he said, with technology for the CT6.

He said the new CT6, which is expected to compete with the Mercedes-Benz S-Class and BMW 7 Series, will have stop-start technology and offer a 3-liter twin turbo engine combined with an eight-seed transmission to offer the most “powerful six-cylinder gas engine in the segment.”

The new CT6 is 53 pounds lighter than the CTS on the road today, but is eight inches longer, Reuss said.

The CT6 also will include a thru-view mirror that displays more of the outside of the back of the car in the rearview mirror. “We’ve taken that rear backup camera and steamed it into the front mirror,” Reuss said.
