Hey,
Can anyone suggest me some topics based on radio controlled cars that I can use for my last year Automobile Engineering PROJECT???
Any topic is welcome. R & D about it can be considered.
That would be very useful. Thank You!

You could try and develop a low-cost active suspension system for RC cars. I'm sure the buggy owners would love it.
As far as doing this for your final year project, it's not an innovative one; Active suspension is already being used on some high-end production cars.
I think enough R&D is done about this already, it just needs refinement now.
The hard part is, you have to miniaturise the existing technology to go on a RC car. 

This is a fine example of Bose active suspension at work--

Good luck   

@anjanbabu: Excellent idea...!!! I would now gather more info about it... & I will see what I can do about it.
I have already studied about this topic in my previous subjects & I know how it works. Problem is about scaling the components to 1/10 of its size so that I can fit it into a Buggy. Well, I am sure I can come out with a solution.
Thnx mate. 

You could probably use some high torque servos for actuation and if you could possibly map the terrain with something like a miniature LIDAR or similar, the ride would be amazingly smooth depending on the resolution of the system. 

Keep us posted on your progress, we'd like to try it to.
