Will Mahindra be able to back up the BE 6e's promised range and performance?

Mahindra has made some very bold claims about the BE 6e's abilities, such as the top variant offering a range of 682 km on a single charge and performance figures that read 6.7 seconds from 0 to 100 km/h. On paper, these numbers look great, but it’s difficult to deliver them in real world conditions, particularly for a company that is still relatively new to the business of producing high end electric vehicles. Values such as fuel economy, climate, and EV dynamics are sensitive to driving conditions and strong functions of climate, as well as battery degradation with time. That brings up the question of how consistently the BE 6e is able to output this performance, especially when it comes to the fast charging and power output over time. The only worry that potential buyers may have is a mixed track record from Mahindra with electronics in their vehicles. Are these claims realistic? Can Mahindra gain the trust of their EV technology? Is the BE 6e all it's cracked up to be, or are these figures overly optimistic marketing claims?
