ISF Performance

The IS F is equipped with a torque-sensing limited-slip TORSEN® rear differential [1] that matches available engine power to changing traction conditions of the rear wheels. This innovative feature intuitively channels more power to the rear wheel with the greatest traction. Unlike conventional traction-control systems, it does so without reducing engine power or applying the brakes to the slipping wheel. Increased traction means more power and a more exhilarating performance through turns and curves.
