Cadillac’s engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6.Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here’s what we know so far:

The CT6’s top engine will be a 3.0-liter twin-turbo V6. It’s the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get.

The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It’s rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That’s an improvement of 14 hp and nine lb-ft compared with today’s 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it’s the highest output for a naturally aspirated V6 that’s SAE-certified and runs on regular fuel.

Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions.

The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS.

Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options.

The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac’s creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.
