Modern technology has benefited the automobile in more ways than you could count on an Excel spreadsheet. Specifically, heavy duty vehicles have benefited greatly in terms of fuel economy and overall drivability. In fact, General Motors plans to introduce 25 new technologies this year to benefit the Chevrolet brand alone.
Today, GMC has put together a brief presentation on how its exhaust brake technology works to assist the driver while piloting the Sierra HD diesel. What the technology does is assist the truck in stopping while descending down hills to reduce the wearing of the truck’s brakes. It utilizes the diesel engine’s turbocharger back-pressure in an efficient matter, because hey, why let all of that energy go to waste?
The feature is driver selectable and standard on every Sierra HD equipped with the 6.6-liter Duramax diesel engine. With the flip of a switch below the climate controls, the system is engaged, and subsequently, flipping it again disengages it.
When it’s activated, the truck will automatically begin slowing down on downgrades without applying the brakes allowing for greater driver control, especially when towing large loads behind the truck. Though, drivers should expect more downshifts from the transmission and not be alarmed by increased frequency of them. In fact, the increased downshifts increase engine speed, therefore heightening the effectiveness of the exhaust brake.
The exhaust brake also works in concert with the cruise-control when active, so there are no worries of the systems clashing with one another.
