AWD definitely better but will have a lower 2nd hand market and slightly reduced fuel efficiency.

I drive a C-HR GT AWD. Fuel consumption is 

Heavy traffic in Colombo 8 - 10kmpl 

Light traffic 10 - 12kmpl

Outstation 13 - 15kmpl

AFAIK ground clearance is a bit more in AWD model than the FWD.

Never had a problem with ground clearance.  More than enough for Sri lankan roads.Very stable at corners and on wet roads than FWD. Pick up is better when climbing mountains compared to the FWD.

Note:AWD system is not always engaged. It activates at initial stage of acceleration or at any sudden acceleration when you need more power, all the other times it drives as a front wheel drive.

The AWD has about 150mm of ground clearance and the 2WD about 140mm.

The AWD system is an updated version of Toyota's Dynamic Torque Control AWD. Basically the torque gets sent up to 10% to the rear under normal conditions. On more challenging terrain the torque can go up to 20 or 25 % or something (not sure about this), and typically happens when the vehicle detects excessive wheel spin in the front (as if it is on extremely icy roads or slippery mountain terrain).

There are three onditions under which Toyota's system diverts torque to the back

a. Acceleration from standstill

b. Cornering

c. Front wheel slippage

The system originated with the Active Torque Control system in the mid 2000s with models like the A30 series RAV4, Highlander, etc.... Overall, it was pretty decent albeit the system performed a lot better with VSC under cornering conditions. The ATC system has a rear diff which has an electro magnetic coupling mechanism which engaged and disengaged when wheel spin reached certain threshholds. The torque that was sent was step wise (at each threshold it would send X% of torque to the rear, which is also the reason why it didn''t work well with cornering and barely did work in cornering) .Then they upgraded it to Dynamic Torque Control system around 2012ish...where they stuck an ECU in front of the EM coupler. The system would dynamically change the level of torque being sent (they did this to improve performance as opposed to keep the car moving on a slippery surface). This sucked !!! Like really sucked. Now they have finally fixed the software and is a lot better.
