Hello aspirant,

Criteria is that candidates must have passed Diploma in Engineering in any branch from a recognised College or University. Admission into B.Tech courses is based on entrance exam or merit obtained in qualifying exam. Entrance exams like TS ECET, AP ECET, UPSEE Lateral Entry Entrance exam, etc are considered by some Engineering Colleges.

So, you can do Diploma in Engineering in any branch. If you can get Diploma in Automobile Engineering then go for it or else go for Diploma in Mechanical Engineering and then take admission into B.Tech Lateral Entry i.e into 2nd year of Engineering.
