M.Tech

Hello Kishan,
I can appreciate your concern and desire to seek advise. However it's best to pursue as per your passion. Where is your passion ? In Automobile or in MT? Go for the one that dictates your heart.
Best wishes

It's Rs. 47,480 per year for M.Tech from PSG College.

Hi Aman,
You can apply to a lot of universities since your CGPA is quite good but which university will admit you is difficult to suggest as it's a university's decision. How selective it is and how strong your profile is as compared to other applicants?The University of Alberta, University of Waterloo, Ryerson University and McGill University are some you can try.

GATE is most probably required for M.Tech in civil engineering.

So far, I haven't seen a college which recruits on GRE in India. Admission happens depending upon on the score of GATE, or state PG exams. You can also try for management quota, but fee will vary from college to college.

The Master of Engineering (MEng or ME) are postgraduate Master's degrees offered by Canadian Universities that is achieved for higher studies in one of the engineering sciences branch or subject. Due to the numerous possibilities for specialisations in the area of Engineering Universities also offer degree types such as the Master of Science in Engineering (MS in Eng.). MS in Engineering subject is equivalent to MEng or ME or M.Tech ( awarded in India)

You are eligible to seek admission in IIT for M.Tech by appearing in GATE.
