GMC revealed, in the United States, its 2015 version Sierra Denali pickup truck. Virtually identical on the outside compared to the 2014 model, the pickup is the first to gain magnetic suspension on the market, which should guarantee less vibration, mechanical noise and lateral movement of the cabin, all without compromising the Sierra's load capacity.

Other new features are the adoption of a system that allows you to control the use of Apple cell phones by voice in the car, as well as sound alerts for receiving messages, which also speaks their content to the driver. The Sierra also comes with a wireless network point for 4G internet from the operator OnStar.

Engine options for the 2015 Sierra remain the same. A 5.3-liter eight-cylinder “v” with 360 horsepower and 52.82 mkgf of torque and a more powerful version 6.2 liter eight-cylinder “v” with 425 horsepower and 63.53 mkgf of torque.
