Don’t forget “AWD”. AWD is not 4WD. |

FWD = Front Wheel Drive.
RWD = Rear Wheel Drive
4WD = 4 Wheel Drive
AWD = All Wheel Drive
With 4WD and AWD, depending on the vehicle, not all the power can go to all wheels, particularly with AWD. |

The AWD systems in modern vehicles are controlled by an ECM: Electronic Control Module. They compute millions of variables that no human ever could, many times in conjunction with stability control. They remove the human factor. As a result, these vehicles are much safer to drive, but they are totally different than 4WD.
I have pushed my Ford Interceptor SUV to it's limits in training. It is an AWD system. The ECM will add power or add braking to individual wheels, dependent on what the vehicle is doing/encountering and the driver input. I have never been able to get the vehicle into a critical state, even at freeway speeds (on a closed track). It is quite amazing, especially compared to the old-school RWD vehicles of the past. Interesting to note that it even did well in our recent snow storm; I had no issues and never got stuck.
Now back to boats... |
