DIFFERENTIALS
The Gleason Torsen differential. This uniquely designed differential applies torque to both rear wheels and distributes torque as required. It will deliver as much as 90 percent of the torque to one wheel, with 10 percent going to the other. The new differential has been proving itself in vehicles ranging from Mario Andretti's race car to the U.S. Army's Jeep replacement. And Detroit is definitely interested. The way engine power is conveyed to the wheels by the drive train affects the way a vehicle gets traction on a road surface. Most of us know about the first two components of the drive train: the engine and transmission. The third part, the differential is not nearly as familiar. That part has traditionally been a major source of mysterious traction problems for many cars. To understand the characteristics of the Gleason differential, it is necessary first to review the "differential problem," as engineers describe it. The problem stems from the basic nature o
