https://www.autocar.co.uk/car-news/technology/uk-based-yasa-claims-world-record-new-738bhp-131kg-motor Mercedes-Benz-owned Yasa Motors has created what it claims to be the highest-density motor ever built – a 13.1kg unit that produces 738bhp. That equates to 56bhp per kg, which is more than double the industry benchmark of 20bhp per kg. UK-based Yasa calls it an unofficial world record for motor power density – across any application or sector, not just automotive. The electric motor with the highest power-to-weight ratio currently in production is the Equipmake HPM-400, which puts out 54bhp per kg. Weighing 40kg, the Australian-produced unit is used in aerospace and marine vehicles. Yasa’s figures were reached during prototype testing last week. What makes the feat most remarkable, says Yasa, is that the unit uses no exotic materials such as cobalt-iron laminations and litz wire. Moreover, it was not created using 3D printing.
