Many automakers create non-functional hood scoops just to add to the appeal of their cars and cheat customers that the hood scoops are an indication of the massive power-train hidden under the hood. However, hood scoops are meant to be functional features that aid in cooling the engine below. GMC uses hood scoops as well, but unlike the many non-functional hood scoops, theirs are functional. This time they have even gone a step ahead and created an innovative hood scoop for the upcoming 2017 Chevrolet Silverado HD.
GMC has revealed that the 2017 Chevrolet Silverado HD trucks will be fitted with their new patented air-intake system. This system helps cool the engine even during difficult conditions. The new hood scoop is part of this system and in addition to making the vehicle look like a muscle car, it helps ensure the engine stays cool for a better performance.
Engine Specs and improvements
How the new air-intake system works to keep the engine cool?
Before we delve into how the system works, we understand that the truck will feature the same engine as the outgoing model. This is a huge disappointment as there were rumors that the engine would be replaced or modified. The heavy duty truck will still feature a turbocharged 6.6 L, V-8 diesel engine that is rated at 397 hp and 765 lb-ft of torque. The engine is mated to a 6-speed Allison automatic transmission system.
Back to the new air-intake system, the automaker says that just like humans and other animals, engines too need to breathe and the new air-intake system helps the Silverado HD breathe optimally. The hood scoop channels 60% of the air needed to cool the engine. This air is much cooler than the air under the hood.
In addition, the scoop also offers the ram-air effect where more air is forced into the engine as the vehicle’s speed increases. In case the hood gets blocked, air is channeled through a secondary intake located in one of the model’s front fenders. However, this is only one side of the new system’s coin. Since engines like dry and cool air, a good intake system should ensure that moisture in the air is kept at its minimum.
To help in this, the new intake system also features an air/water separator which sends air through a 180-degree turn before it reaches the engine. By doing this, any moisture in the air consolidates into large droplets. These droplets are then flung onto the wall of the engine’s housing to drain away by centrifugal force.
To ensure the system is good under many weather conditions, it was taken through rigorous testing. According to the automaker, its engineers simulated all possible types of precipitation. The truck was also tested in different temperatures to gauge its performance in extreme heat and cold environments.
The automaker even tested the truck at the Eisenhower Tunnel which is the highest vehicle tunnel in the globe. This tunnel also has the highest elevations in North America. This was done to ensure the trucks provide maximum utility to customers even in extreme environments and situations.
2017 Chevrolet Silverado HD Exterior
Other than the new functional hood scoop, other exterior features are carried over from the outgoing model. Though only scarce information is available as of this writing, we understand that the Silverado HD features a cheese-grater grille which is flanked by projector beam headlights and LED DRLs.
Even on the sides, everything looks unchanged including the chromed towing mirrors, chrome-plated huge wheels and the side steps which are also finished in chrome. More information will be availed by the automaker later.
2017 Chevrolet Silverado HD Interior
GMC has not released any information about the upcoming Silverado HD interior as of this writing. However, I have a strong feeling that the cabin will remain largely unchanged compared to the outgoing model.
The automaker is only likely to modernize the current features and probably add more connectivity and safety technologies. The current model had undergone significant changes in the cabin; so many changes are not expected.
Price and release date
The price of the 2017 Silverado is also a mystery as of now. However, due to the innovative hood scoop, I expect the model to be slightly expensive than the outgoing model. The trucks will be delivered to dealerships this fall.
