[QUOTE="Relaxed Chaos, post: 16860826, member: 64993"] There's a trade-off between motor efficiency and size. The torque comes along for the ride. Minimizing electron consumption at low loads (highest use case / most miles driven at a specific torque/amp load) drives the selection of appropriate sized large motors. The extra torque is just available to use as far as the cooling systems allow. Smaller motors result in less efficiency at a given torque/amp and therefore higher amp draw and less vehicle range. The vehicle weight is driven by the batteries, which have trade offs as well. Like everything everywhere, there are trade offs to be made. There are very few win- wins in life; most everything is a balance of competing oppositions. [/QUOTE]
