SPOILER POSITION
Computer automatically deploys tailgate into a spoiler position at highway drag inducing speeds, for best aerodynamics improving mileage, and then closes it as vehicle comes to a stop. The system may also improve trap speed and ET in the 1/4 mile. Stability can be improved in the spoiler mode through a downward force applied to the rear axle on slippery roads at speed.
Interesting...
