I'm wondering if the AWD system on my car routes more power to the rear while the car is in Sport Mode. Does anyone know?
I'm seeing that under normal conditions with the car in Drive, the power distribution is like 90-95% FWD unless traction is needed at the rear. But some cars are programmed to alter that power delivery depending on driving mode.
Thanks in advance!
You are correct, during normal driving the car is FWD, until it senses that there is no traction, or is slipping. Then it sends power to where it needs it to keep the car steady and moving.
In sport mode, I believe(somebody correct me if I'm wrong) that it only affects the throttle response, and the time/RPM for gear changes. In normal mode, the car will basically "Overdrive", it will put the car in the highest gear possible for the lowest RPM's for the best fuel economy. In sport mode, the car will try to keep the car in a lower gear, keep the RPM's higher where your kind of in the middle of your hp/torque curves, so that you can get er going bettter. In sport mode the throttle will be more reactive and quicker, resulting in "I am speed".
The only way that something will affect your AWD, is when you shut off
DSTC and traction control. First of all, when you shut it off
, it doesn't actually disable, it just let's you slide around more. So basically, when you shut off DSTC, the car will let you have some fun, then when it thinks you've had enough fun it will kick in and help you out. What this means in Haldex terms is: When DSTC is on, the haldex system will take something like 0.7 of a slipping wheel rotation to kick in, and fix/correct the slip. When DSTC is off, the system will let you get away maybe 2-5 of a slipping wheel rotation before it kicks in and stops the fun.
I hope I cleared some things up, and didn't make anything worse.
