Let’s look at 2018 GMC Terrain aerodynamics, for example. GMC Terrain engineers clocked in more than 300 hours in the GM wind tunnel to study the Terrain and refine each surface to make it as aerodynamic as possible from front to back.
What did the engineers achieve? For starters, the Terrain boasts a lifted stance, which means air flows beneath it and pressurizes chassis components; this boosts aerodynamic drag, which can decrease fuel economy. To fight against this, engineers were able to develop a way during testing to guide that air to the rear of the vehicle.
“Reducing the aerodynamic drag of an SUV is always a challenge,” explained GMC Aerodynamic Engineer Alicia Bidwell. “Our engineering team paid attention to even the smallest details to deliver the size and cargo space our customers want.”
The work that Bidwell and her team did on the GMC Terrain ultimately led to a three-mile-per-gallon increase for the SUV. Thanks to that team, the GMC Terrain boasts 26 miles per gallon on the all-wheel drive platform.*
