Dear Mr
Re: 1-1775868872
My technical team have now got back to me in regards to your enquiry, please see response below:
The AWD system in the CX-5 is not marketed as a full-time four wheel drive system, and is really only a device to assist the vehicle in getting off wet fields etc. As you would when towing a caravan.
The system has torque limitation, whereby it will cut off power to the electronically controlled rear AWD coupling if the level of wheel spin detected at the front wheels is too high, to prevent damage to the AWD system.
In normal driving conditions, all drive is supplied to the front wheels only, however,
when wheel slip or wheel spin is detected, up to 50 of the torque can be transferred to the rear wheels by means of an electronically controlled rear coupling, although this is of course a maximum, which the amount of torque being transferred being constantly variable. The system may also not operate if the temperature of the oil in the rear differential is too high, or if the handbrake is applied – In the case of the video, it could well be that the handbrake has been applied to prevent the vehicle rolling back down the slope, which would also prevent any drive been sent to the rear electronic coupling
I have checked with the brand team, and also the technical information we have available to us, and there is no information relating to an upgrade or improvements to the AWD system on this model.
If you have any further questions feel free to call us on 03457 48 48 48. We are here between 9.00am to 6.00pm Monday to Friday.
Yours Sincerely
Martina Reed
Customer Relations Executive
