Truck Test Drives at GM's Milford Proving Ground

I had a chance to compare the capabilities of several full-size trucks at GM's Milford Proving Ground, a facility with 130 buildings on a 4,000-acre site in Michigan. Courses wind around four lakes and are equal to over 138 miles of two-lane highway, enough to provide a variety of road-tests that simulate conditions we all encounter in the real world.

Most tests focused on vehicle stability control, traction, and towing abilities.
