I have been looking for the front/rear power ratio info on the AWD model of the Terrain for a while. The dealer couldn't tell me and when I ask GMC directly they had some trouble locating the info. After two week they finally found an answer for me and I thought other people would be interested in the response.
This is copied directly from the email they sent me:
Greetings from GMC customer Assistance Center!
I am very sorry for the delay in providing answer to your inquiry. Here is the information that I was able to gather.
Torque split - torque delivery to the rear is constantly changing in response to driver input, vehicle state and traction available. For example:
• On a high coefficient wide open throttle launch, 20 to 50 percent of the torque will be sent to the rear wheels to eliminate front wheel spin and maximize vehicle acceleration. Changes with vehicle speed.
• Front tires on glare ice, rear tires on high coefficient, 100 percent of torque will be delivered to the rear and reacted by tires there
• Steady state road load at highway speeds – essentially 0 torque to rear for reduced drag
• Low coefficient surfaces – wheel slip input is a large part of torque distribution calculation. 0 to 100 percent rear depending on where traction is highest
We hope the information inscribed through these sights would aid you in your search and we wish you good luck with your future endeavors.
Again, thank you for contacting General Motors.
Sincerely,
