Just to add to that, the Nissan Leaf was fitted with a motor in the rear. The resulting powertrain made 300hp and 500tq presumedly with the same 62kWh battery.

Looking at the Tesla Model 3 Long Range Plus or Performance model, the 75kWh battery pack and dual motors make either 346hp and 376tq or 450hp and 471tq. I don’t know if the extra hp/tq comes from software or hardware changes. The battery is 20% larger on the Tesla, so I don’t know what the Nissan would have for power and torque with the larger battery. I don’t know how the motors compare in efficiency. Either way, take it for what it is, but they achieved more torque with a smaller battery on a test vehicle.

It gets more confusing when we consider whether the quoted battery capacity is gross vs net, and it gets confusing when so much can be controlled with software. EV West sells a 500hp/800tq crate engine, but that requires a certain battery to achieve those numbers. Anything providing too much current could fry the motor too, so these things have to be sized right and have controllers. When range, recharge/discharge rate and battery longevity is all considered, what the powertrain could do and what it can do and what the manufacture allows it to do are often different things.
