Full time 4WD or permanent 4WD have permanently fixed torque split between front and rear axles/wheels and is always driven in 4WD mode...the driver has no option to move to 2WD. AWD name is used here also, as technically, all the wheels are powered ! Examples are Rexton AT and Toyota Fortuner

AWD name is used on vehicles with Automatic AWD. Here the vehicle is predominantly driven in 2WD mode and as and when the vehicles computer detects a slip in the driven wheel/axle, directs a part of the torque to the other axle, thus becoming a 4wD temporarily . These vehicles have a lock switch, which can convert the vehicle to a permanent 4WD mode by locking th torque to both axles. Examples are Mahindra XUV500 AWD, Tata Aria , Rexton MT

As the naming convention used across the world are different, AWD, full time 4WD are being used interchangeably !

Having a low range gear is an additional option and is possible both version..example Fortuner and Rexton MT

That could be because they are opening bookings in phases and hence only now all cities are covered. Besides, there has been no ads for the Rextron but it is slowly coming up. Also if i am not wrong, the numbers shown are the numbers which Mahindra could assemble and deliver to customers. It does not depicts the number of bookings. They are apparently planning to increase the assembly line based on demand and I will not be surprised if it starts selling 500 Rextrons every month considering how the base version is priced dangerously close to the the XUV top version. So I am keeping my fingers crossed that Mahindra has another winner at hand.

Has anyone purchased this yet? Going by the history of the company does not make one feel positive. Is there any visibility to the future of this vehicle? Would this become another Daewoo or would Mahindra support this?Nitin

Ssangyoung is a subsidary of M&M so there should be no doubt about the future. Go through the news below in today's ET

Rexton just like the Fortuner comes with AWD plus proper 4x4 with low range.

News to me. Automatic which i drove did not had proper 4x4 with low range as you put it. Yes that is there in manual.

Only Manual has low range. Automatic doesn't have low range.

AWD systems are generally of two types. One in which all 4 wheels are always engaged like in Rexton, Fortuner, Land Cruiser etc. The other is the systems prevalent in soft roaders like CRV, XUV500, etc where the AWD system kicks in only when wheel slippage/loss of traction is detected. This system is never meant to be used as Full Time 4WD. This is more like on-demand 4WD without driver involvement.

This is not necessarily two. Full Time 4WD/Permanent system means that there will be a open center differential. Generally they cannot be switched to 2WD, but there are certain exceptions like Pajero 2.9 which can be driven in 2WD mode by disengaging the center differential from transferring power to the front. You can also drive it as Permanent/Full Time 4WD by engaging the front differential.

Even the lock is only for limited usage to get out of a tricky situation, once you cross a set limit, the lock will disengage automatically.

I think you are right. But since the Subaru has been using term AWD for their full time 4WD, I always associated with the AWD with full time 4WD. But now I see even 'part time 4WD' cars like Captiva, XUV are called AWD.

Again, part-time 4wD is not the correct name to call these vehicles like XUV or Aria. Part time 4WD are vehicles where the driver decides when to shift to 4WD by physically moving a lever or turning a switch. Examples are Mahindra jeeps, Tata safari etc.
Better name is automatic AWD..

Centre differential is not related to switching between 2WD and 4WD , probably you meant transfer box. If so, then it becomes a part time 4WD where the driver decides when to shift to between 2WD And 4WD.

Permanent 4WD vehicles "need" to have a central differential but it need to have locking mechanism to get out of tricky situations. Toyota Fortuner has this locking position in the shift lever where the driver can lock the centre differential . However , as soon as you are out of the mud/slush you need to unlock as otherwise the transmission is likely to get damaged if driven on hard paved roads.

Rexton AT does this intelligently using the traction control and the ESP system. It has a open centre differential but does not have a mechanical lock. The ESP system kicks in and brakes the spinning wheel thus getting the Rexton out of mud/slush..

I am now well versed what a center diff is and a what a transfer case is. I was contradicting your original claim that Permanent 4WD or Full Time 4WD vehicles cannot be run in 2WD mode. They can be as in the case of Pajero 2.8 which can be driving in Full Time 4WD or 2WD mode since the manufacturer has given the option in the 4WD Selector. It is theoretically possible in the Fortuner/Land Cruiser etc, but they have not given the option.

That becomes a part time 4WD then. The driver can select between 4wD and 2wD based on his requirement
