SOURCE: A high pitched whining noise in the engine.

Some questions:
- Does it happen when standing if you raise the RPMs up to 2-3,000? If yes, listen closely to the alternator.
- Is it related to road speed?  If so, then you should put it on a chassis lift, wheels free, then cause it to happen by putting it in gear and raising RPMs to road speed.
I suspect it isn't the acceleration that causes the pitch to change but rather engine RPMs.
You could check this while on the road by starting in a lower gear and noting when the whine is very noticeable, then slip into the next higher gear to see if the whine changes or remains the same. If it remains, it probably isn't related to the engine but to some rotating part(s) outside it (for example, wheel bearings.) If it changes, then the noise is coming from some engine component and alternators can do this when the amperage load is high; it's also a part that turns at a fairly high speed and will 'whine' rather than 'growl.'        

SOURCE: How do I diagnose a loud whining noise from the

It sounds like it is def. the wheel bearing. If you can get it on a hoist and let it down with something to stop one side of vehicle at a time and let other side spin freely you will likely be able to determine which side. Or if you have no hoist, jack up vehicle one side at a time and spin wheel listen for growling and also move tire in and out to check for looseness.

you could be low on transmission fluid check that and make sure it registering properly on the dipstick.

I have the same problem with my car I think its the torque converter clutch but you should visit a diagonestic machine just to find out

SOURCE: above speed of 80 km/h slight vibration can be felt and continues

if you google "grand vitara vibration" you will find a discussion board about the many many grand vitaras getting around with a vibration problem. I happen to be one of these people and am seriously thinking of selling the car after all the problems I have. It appears to be a drive train design fault which will cost a fortune to fix, believe me its not a tyre problem, ive had 4 wheel alignlents and balances and it never seems to fix the problem.Take it to a mechanic and let them have a good look at it.
