POWERFUL 3.6L ENGINE
There is no overlooking the aggressive power of the CTS Coupe. However, the efficiency with which that power is dispersed is where the true engineering genius can be felt. A powerful 3.6L direct-injection engine delivers 318 HP while the 6-speed automatic transmission provides smooth and effortless shifting. Reduced emissions are achieved through the use of direct-injection technology when compared to engines without it.

Direct-Injection
Direct injection moves the point where fuel feeds into an engine closer to the point where it ignites, enabling greater combustion efficiency.
Composite Intake Manifold
The upper intake manifold for the 3.6L V6 is made from composite material and provides mass savings over an aluminum manifold, with a carefully designed structure that helps ensure quiet engine operation.
Aluminum Engine Block
This aluminum-intensive construction means less weight and greater efficiency than conventional cast-iron engines—and less weight translates to improved vehicle fuel economy16.
