Aerodynamic 2014 Sierra Cab Design Bolsters Fuel Efficiency

2014-GMC-Sierra-Wind-Tunnel-Front-mediumGMC sought out to create a more aerodynamic, quieter pickup in its 2014 Sierra, so the automaker entered the wind tunnel.  GMC spent more time testing the 2014 Sierra in the wind tunnel than any pickup before it, and the result of extensive testing was just what they were looking for.

“We can’t stop air; we can only guide it through the path of least resistance. It’s like electricity, without the shock,” said Diane Bloch, GM aerodynamic performance engineer, in a press release. “The biggest misconception is that it’s all about single components. But a certain side mirror design doesn’t create a certain amount of drag, its interaction with the rest of the vehicle does.”

To find out which designs guided the air most efficiently, GMC utilized a 750-foot-long tunnel equipped with fan measure 43-feet in diameter.  The massive fan was able to generate wind speeds of up 138 mph inside the tunnel.

GMC modified things as significant as the tailgate to aspects as seemingly insignificant as add-on bug deflectors, in order to ensure that the 2014 Sierra is one of the most fuel efficient pickups on the market.
