Cadillac CT6 Will be Lighter than CTS, Offer 70-MPGe PHEV Variant

Details regarding the new Cadillac CT6 flagship have started to trickle out over the past few weeks, with the newest piece of information being that there'll be a PHEV variant of the CT6 that will reportedly achieve more than 70 mpge.

The Detroit-based automaker described the 70 mpge estimate as "industry leading," and it's confident the CT6 will achieve such ratings due to its super lightweight construction with materials lighter and stronger than aluminum. 2014 Cadillac CTS Vsport Introduction© Provided by MotorTrend 2014 Cadillac CTS Vsport Introduction

“We will create with the CT6, the world’s most advanced body structure,” said GM product boss Mark Reuss.

Using a mixed material body structure that combines high-strength steel, aluminum, and steel stampings and castings, the CT6 will use 20 percent fewer part to reduce weigh and complexity. Although it's 8 inches longer than the CTS, it's lighter by 53 lbs, according to The Detroit News. In addition, the automaker says the new structure helps improve safety, ride, and handling, while also keeping things quiet inside the cabin. Also helping in terms of fuel economy will be stop-start technology.

The CT6 will offer a 3.0-liter twin-turbo V-6, which Cadillac claims will be the most "powerful six-cylinder gas engine in the segment." The mill will be paired with an eight-speed automatic transmission, and inside, the CT6 will boast new pieces of tech including a thru-view mirror that displays a wider view of the back of the car than a conventional rearview mirror. While we previously thought the CT6 would compete against the likes of the Mercedes-Benz S-Class and BMW 7 Series, Cadillac CEO Johan de Nysschen said the flagship isn't meant to be positioned against them directly. Instead, he said it will offer similar refinement but more technology and a smaller body. 2014 Cadillac CTS Vsport Introduction© Provided by MotorTrend 2014 Cadillac CTS Vsport Introduction

Cadillac's flagship is expected to go into production at GM's Detroit-Hamtramck Assembly Plant late next year, and we can't wait to see if the new CT6 can walk the walk.
