Their total energy storage capacity is quoted as 3kWh, which translates to 4 horsepower-hours.
Just as people start to get comfortable to the somewhat-odd kilowatt-hour unit of energy -- for reference, the SI unit for energy is the Joule; 1 kWh == 3.6 MJ -- here comes the cursed non-metric unit of hp-h lol
That aside, this was a decent albeit short read about engineering and compromise. Where engineers really shine is when working within constraints, whether it be for vehicles, computers, or buildings. From civil engineering, there's an informal saying that anyone can build a bridge that will stand, but few can build a bridge that will stand while using the least budget and amount of material.
