( http://www.TFLcar.com ) The 2012 Cadillac CTS Sport wagon and the Infiniti M56 both come with all-wheel-drive. The Cadillac's Borg Warner system "uses sophisticated controls and algorithms to augment vehicle handling and traction by optimally using grip at both the front and rear wheels," according to Cadillac. It can shift up to 100% of available torque to the front axle if needed.

The 2012 Infiniti's M56x All-Wheel-Drive system is designed "specifically for a front engine/rear-wheel drive biased setup. 0 to 50 percent of the power can be sent to the front wheels for better control. The active brake limited slip differential can shift power side to side.  The system uses an advanced torque split control strategy that automatically redistributes torque to the wheels (0:100 up to 50:50 front to rear) according to road and driving conditions." according to Infiniti.
