Chicago, Illinois – Production has begun on the electronically controlled, full-time four-wheel drive system used in the new HUMMER H2. The BorgWarner system is integrated with the powertrain, and is standard on the H2.

The system is capable of further multiplying the vehicle’s gear ratios by 2.64:1 when necessary, for highly controlled obstacle climbing. It provides a 40/60 percent front-to-rear torque split in “High Open” or when the differentials are unlocked, and a 50/50 percent front-to-rear power split when the transfer case differential is locked. BorgWarner also supplies the transfer case electronic control unit, which provides five mode selections including rear axle differential lock, to provide optimum performance under all types of driving conditions.

“H2 provides excellent on-pavement power, performance and control for everyday driving and routine tasks like trailer-towing,” said Timothy M. Manganello, BorgWarner President and Chief Operating Officer. “But its true character really shines in the off-road arena. It can easily soldier over rocks and through the harshest terrain. BorgWarner is proud to provide such a vital element of this exhilarating, uncompromising vehicle.” The system is produced in Muncie, Indiana.
