Porsche developing next-generation four-motor electric powertrain

By [email protected] (Unknown) Porsche Engineering have revealed they are working on a torque control system for a next generation four-motor all-wheel-drive electric SUV powertrain that provides maximum stability and safety in every situation—without additional sensors on board. What makes a four-motor powertrain desirable isn’t so much more power, but more control. Each motor can be controlled individually and immediately, rather than relying on analogue mechanical differentials and inefficient hydraulic braking systems that don’t react as fast or as precisely. Solid state digital control is good for safety and stability in inclement weather and for improved performance and handling in dry weather. Basically,
