General Motors has unveiled an updated version of the GMC Sierra HD frame pickups. The modernization affected the medium-duty models, which are indicated by the indices 2500 HD and 3500 HD.
The design of the front of the cars was changed - a radiator grille of a new configuration was used with several options for the grid pattern and even more “fat” chrome trim. Daytime running lights have been moved under a single glass of headlights, the graphics of the rear lights have been changed.
Inside, there is an improved media system with a large 13.4-inch screen. A 12.3-inch digital instrument cluster is also available as an option. Improved quality of finishing materials.
The units have been upgraded. The 6.6-liter Duramax V8 turbodiesel now develops 477 hp. power and 1322 Nm of torque (+26 hp and +88 Nm relative to the old version), it is combined with a 10-speed Allison automatic. The petrol 6.6-liter V8 still produces 401 hp. and 629 Nm, but now it is aggregated not with a 6-speed automatic transmission, but with a 10-speed one, like the diesel version. The drive at the choice of the buyer can be rear or full.
The 2500 HD has a payload capacity of up to 1.7 tons and a maximum trailer weight of up to 10.2 tons. For 3500 HD, the parameters are up to 3.3 tons and up to 16.3 tons, respectively.
The Transparent Trailer View system has been improved, which is a rear-view camera that shows what is happening behind the trailer. It has become compatible with low bed semi-trailer and trailer. The "blind" zone monitoring complex can now extend its action to the spaces around the trailer / semi-trailer.
Cruise control has become adaptive - it is able to recognize and compensate for the loss of a given speed in situations where the car is towing a load with a large windage. At the same time, in this scenario, the system increases the distance to the vehicle in front. The built-in scales in the cargo platform are able to warn the driver about exceeding the maximum permissible vehicle weight established by the manufacturer.
