You are exactly correct. However, some of you have been talking about other Acura SH-AWD cars as if they all work the same. They do not.


2005–2008 RL SH-AWD operating parameters include:
During straight-line cruising and moderate cornering below about half throttle, up to 70 percent of the torque is delivered to the front wheels
In full-throttle straight line acceleration, up to 40 percent of the power is sent to the rear axle
In hard cornering, up to 70 percent of available torque goes to the rear wheels for enhanced chassis balance
Up to 100 percent of this torque can be applied to the outside rear wheel if the situation dictates
SH-AWD is active in second through fifth forward gears

The 2009 RL was updated to have more aggressive intervention of SH-AWD to give the car more rear-wheel-drive-like handling characteristics. 2009 RL SH-AWD operating parameters include:
During straight-line cruising and moderate cornering below half throttle, up to 70 percent of engine torque is delivered to the front wheels.
In full-throttle straight line acceleration, up to 40 percent of the power is sent to the rear axle.
In hard cornering, up to 70 percent of available torque goes to the rear wheels for enhanced chassis balance. Up to 100 percent of this torque can be applied to the outside rear wheel that can also be overdriven up to 5.7 percent by a built-in acceleration device.
SH-AWD is active in all five forward gears



RDX SH-AWD operating parameters include:
Up to 90 percent of available driveline torque can be transferred to the front wheels during high-speed driving
During straight line full-throttle acceleration, up to 45 percent of available torque can be transferred to the rear wheels
In hard cornering during acceleration, up to 70 percent of available torque can be directed to the rear wheels for enhanced vehicle dynamics
Up to 100 percent of the torque sent to the rear axle can be applied to either rear wheel as the conditions dictate

MDX SH-AWD operating parameters include:
Direct Yaw Control promotes precise line trace in all conditions
Full-time "active and intelligent" all-wheel drive requires no driver interaction
SH-AWD direct control electromagnetic clutches provide ultra-quick response
Grade logic control allows worry-free starting on steep grades with up to 70 percent of available torque being sent to the rear wheels
Up to 70 percent of available torque can be directed to the rear wheels during hill climb acceleration for maximum traction
Up to 50 percent of available torque can be transferred to the front wheels during cruising to help maximize fuel efficiency
In hard cornering, up to 50 percent of available torque can be directed to the rear axle for enhanced chassis balance and increased cornering capability
Up to 100 percent of the torque sent to the rear axle can be applied to either rear wheel as the traction conditions dictate
37 percent increase in rear torque capacity as compared to the previous MDX VTM-4 system
7 percent reduction in weight compared to the previous VTM-4 system


TL SH-AWD operating parameters include:
Up to 90 percent of available torque can be transferred to the front wheels during normal cruising.
In hard cornering and under acceleration, up to 70 percent of available torque can be directed to the rear wheels to enhance vehicle dynamics.
Up to 100 percent of the torque sent to the rear axle can be applied to either rear wheel, depending on conditions.
