While developing the 2018 GMC Terrain, GM’s engineers spent over 300 hours in the wind tunnel, trying to make sure that every surface was as aerodynamic as possible.
It’s the same type of attention to detail that goes into NFL footballs as well, as airflow is also an essential factor, while velocity, the direction of motion and spin rate are critical.
“Reducing the aerodynamic drag of an SUV is always a challenge,” said GMC aero engineer Alicia Bidwell. “Our engineering team paid attention to even the smallest details to deliver the size and cargo space our customers want.”
Because of its lifted stance, the Terrain boasts improved airflow underneath, pressurizing the chassis components, thus increasing aerodynamic drag. In order to achieve their goal, GMC engineers did their best at effectively guiding the air to the back of the SUV.
“The styling that you can see – and the mechanical components that you can’t – work together in perfect aerodynamic harmony,” added Bidwell. “Ultimately, this means up to 3 more miles per gallon for the Terrain driver for an EPA-estimated 26 mpg combined for AWD models.”
Of course, airflow is essential not just for vehicle performance, but for football aerodynamics as well – something Wilson will focus on ahead of next month’s Super Bowl LII, when the New England Patriots will meet the Philadelphia Eagles.
“Many look at our NFL football and see it as a simple object,” says Daniel Hare, aerodynamics research engineer for Wilson Sporting Goods. “However, the amount of engineering, particularly in the area of aerodynamics, that has gone into the ball is pretty extraordinary. Every millimeter of the football has been designed to maximize the airflow around it so we can extend its flight, reduce drag and help maintain stability as much as possible.”
So while there is an argument to be made in favor of the 2018 Terrain’s aerodynamic properties, we wager that its improved connectivity features, active safety tech, and two new nine-speed gearboxes will be what ultimately attract buyers the most.
