I have done a master's in mechanical engineering, and i have a good knowledge or understanding of the functioning of electric vehicles. I want to build my own startup company. For starting my idea, i have few queries:

How can I design a model to enter the fast expanding EV sector of today?
How can I use these techniques to make our brand unique and attract business?
Which of range, battery life, or technology most interests buyers?
