Which is quite the contrast to Mercedes new axial flux electric motor, which goes all in on rare earths- the design relies on the highest end high-grade permanent magnets.
Still, presumably Mercedes ambitions are for few motors than BMW or Renault.
Vastly different target market and/or features there. Mercedes are chasing maximum power density, minimum weight for high performance deployments, with seemingly little concern for cost or supply chain.
Renault is going after the consumer market with these motors, where minimising cost and maximising availability is more important than pushing past 95% efficiency or cramming a 700kW power output in a motor that is small and light enough to fit inside of a wheel hub.
