% of power split between front to back??

GUNGASLOW · 09-21-2018, 02:33 PM

Does anybody know what the % of power between the front and rear is in 4wd sport? I’m guessing regular 4wd is 50%front/50%rear... and 2wd is 0%front/100%rear... what is 4wd sport?

It is always 100% rear unless there is slippage. Then the computer gives as much as is needed to the other wheels. It is not fixed. In 4wd sport, it allows for more rear end slip than regular 4wd. Apparently car and driver got a faster time on lightning lap in regular 4wd because of reduced slip.

So what’s faster in launching for 1/4 mile? 4wd or 4wdsport?

It has to be 4wd bc what you don't want on a 1/4mi run is extra slippage.

4wdsport is for allowing a bit of drift when cornering as it allows the back end to break loose a bit before pushing the power to the front wheels.
