To create enough force to lift the car using linear motors requires massive copper coils and rare earth magnets, which is heavy and expensive. It’s also wasteful, because in real world drive cycles peak force is only needed for short periods of time and at relatively low linear velocities. Further, linear motors require significant packaging space which requires the chassis be designed around it. Instead, we use a much smaller motor and a high “gear ratio” using hydraulics to achieve high forces via mechanical gain. This reduces raw material cost by a factor of >10x while achieving similar performance.
