6.2L Supercharged V8 engine

  • Delivers 556-hp and 551 lb-ft of torque
  • Propels the CTS-V Sedan to 60 mph in 3.9 seconds
  • At the heart of this power is a twin-rotor supercharger – each rotor featuring an extra lobe and twisted 100 degrees farther than normal for smoother, more efficient airflow, less noise, and less vibration
