GM Considering Active Aerodynamics for Big Pickups

GM is studying whether automatically opening and closing the grille inlets of its full-size pickups could improve aerodynamics and gas mileage, according to a report in Automotive News.

"You have to look at more expensive solutions more aggressively unless you are going to give up payload. And we decided we don't want to do that," said Rick Spina, GM's global vehicle line executive for full-sized trucks.

So-called active aerodynamics are also being considered by Ford for its next-generation F-Series pickups.
