We built the Sierra 3500HD to deliver everything you expect from a heavy-duty truck – and then we exceeded those expectations with our most powerful Sierra HD ever.
Features & Benefits
OFFERING UNMATCHED CARGO BOX INNOVATION
Integrated CornerStep rear bumper that provides easy access to the box. Four upper tie-downs to help you manage cargo of many shapes and sizes.
TRAILERING & HAULING
We engineered the new 2015 Sierra 3500HD to exceed your performance expectations, pushing it to the limit to deliver the kind of capability you demand.
Standard Trailer Sway Control technology helps keep both you and your trailer heading in the proper direction automatically, using sensors to detect the rocking of a swaying trailer and then applying the brakes to bring it back in line.
To let you engage an extra measure of braking confidence on long grades or in Tow/Haul mode, Sierra 3500HD uses various technologies to help ensure you stay at the desired speeds.
REAR VISION CAMERA
The available Rear Vision Camera helps to provide more clarity and peace of mind while manoeuvring and parking your Sierra 3500HD – even in the tightest of spots. It helps provide a view behind the vehicle that is displayed in the radio screen.
SAFETY ALERT TECHNOLOGIES
To help avoid trouble, Sierra 3500HD is the first heavy-duty pickup to offer the new available Driver Alert Package, including Forward Collision Alert, Lane Departure Warning and the Safety Alert Seat.
DURAMAX 6.6L V8 TURBO DIESEL
The available Duramax Diesel in the Sierra 3500HD delivers 397 hp and 765 lb.-ft. of torque. Paired with the sophisticated Allison® 1000 Series transmission with overdrive, it is the most powerful Sierra HD ever with a proven track record.
ALLISON 1000 SERIES TRANSMISSION
The enhanced Allison 1000 is strengthened to handle the higher torque capability of the Duramax 6.6L engine, while also providing seamless assistance with the exhaust brake system.
DIRECT INJECTION TECHNOLOGY
For fast starts in cold weather, quiet operation and maximum efficiency, the direct injection system helps Sierra HD, with the available Duramax 6.6L V8 Turbo Diesel engine, start in as little as 3 seconds at -34°C.
VARIABLE VALVE TIMING
The Vortec 6.0L V8 with Variable Valve Timing (VVT) is up to almost any task, delivering power when needed by monitoring, opening and closing valves for near-peak levels of torque across a wide range of engine speeds.
