2015 GMC Sierra 1500 pickup truck achieves additional MPGs through direct fuel injection


For precise fuel distribution and fast, efficient combustion, all engines benefit from this technology. Gasoline is injected directly into the combustion chamber of the cylinder, allowing for a higher compression ratio.

2015 GMC Sierra 1500 pickup truck has Active Fuel Management that  can activate or deactivate cylinders based on power demand


By sensing load and power demand, Active Fuel Management™ activates or deactivates four of the engine’s eight cylinders (two cylinders on V6) to meet driving conditions.

For responsive driving and bold power, this technology allows for different valve timing at different engine RPM and operating conditions to maximize performance.


The 2015 Sierra's state-of-the-art available safety and driver alert technologies provide peace of mind and help prepare you for the unexpected.



Sierra’s advanced technologies pair intelligent engineering with driver-centric safety, using cameras or ultrasonic sensors to watch where you might not be looking. These available technologies include:


  • Forward Collision Alert and Lane Departure Warning. Sierra is the first pickup to offer these technologies, which let you know when you are approaching another vehicle too quickly or when you’ve left your driving lane. Both provide visual alerts and allow you to choose from additional audible signals or seat vibrations
  • With Lane Departure Warning, either the left or right side of the seat vibrates, depending on the direction of lane drift. Forward Collision Alert signals both sides of the seat to vibrate


The available Rear Vision Camera displays a view of what is behind you on the radio screen, helping to provide clarity and peace of mind while you maneuver and park your Sierra.
