No way it's going to be in the V. They're not going to make 556hp out of a TT v-6, so why would someone downgrade from the current V? It'll be in the base models, making probably 330hp.

Agreed...no V mentioned in the article

Cadillac Twin-Turbo Debuts in All-New 2014 CTS Sedan

DETROIT – Cadillac today announced details of a new Twin-Turbo V-6 engine and eight-speed transmission – firsts for the brand and signature features of the all-new 2014 Cadillac CTS midsize luxury sedan debuting next week at the New York Auto Show.

The Cadillac Twin-Turbo V-6 is the most power-dense six-cylinder engine in the midsize luxury segment – a 3.6L with 118 horsepower per liter (88 kW/liter) – and the eight-speed automatic enhances fuel economy and acceleration over a six-speed automatic.

“The new Cadillac Twin-Turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan,” said David Leone, executive chief engineer. “Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac.”

Rated at an SAE-certified 420 horsepower (313 kW) and 430 lb.-ft. of torque (583 Nm), it is the most powerful V-6 ever from General Motors. It also has 15 percent greater power density than BMW 535i’s turbocharged 3.0L six, which is rated at 300 horsepower (223 kW), for a ratio of 100 horsepower per liter (74 kW/liter) – and even the BMW 550i’s TwinPower 4.4L V-8, rated at 400 horsepower (298 kW), or 91 horsepower per liter (68 kW/liter). Power density is a measure of efficiency for an engine’s size.

Oh man, impressed with the power at 420. Didn't think they would be that ballsy. Nice!

jeeze okay maybe the baby V... calm down

It might be going into some GM car... someone swap one in a 3000Gt... I will do it myself once I find one in a salvage yard.

10.2:1 compression, I bet that it feels a lot more like a v8, than a boosted v6.

8 speed auto? I'll take 6 speed manual thanks!

- 10.2:1 compression ratio

Interesting, I wonder how much boost it can handle

- Patented, integrated charge air cooler system with low-volume air ducts

I'd like to know more about this.

Taking a page right out of BMWs book... very smart move. Should be exciting to see how they stack up to the N54/N55.

I'd like to know more about this.

There are plenty of cars at 11:1 and higher running upwards of 40 psi.
Now, the rods, crank, gaskets, I have no idea how strong this gm setup will be.
