Sen ska man ju till med reducerande växellåda som kanske väger 5kg.
Känns som att någon amerkan läst att vikten var 22 och antog det var pounds dom pratade om och inte kg.

Equipmake skriver ju så här på hemsidan:
PROTOTYPE MOTOR DESIGN & DEVELOPMENT
Years of development in the field of permanent magnet motors has resulted in Equipmake developing motors with class leading power densities of 9kW/kg.
Equipmake announces the world's most power-dense electric motor.
We last caught up with Equipmake back in 2018, when this British company's spoked magnet electric motors were capable of generating a monster 9 kilowatts of power per kilogram, using cheap materials and standard manufacturing processes. By comparison, the company says its best permanent magnet rivals are still languishing at around 5 kW/kg.
Now, the company has decided to take advantage of additive manufacturing to see how far they can push this thing, and the results could be revolutionary. Its upcoming Ampere motor is projected to weigh less than 10 kg (22 lb) and make a whopping 220 kW (295 hp) at a sky-high 30,000 rpm, meaning it offers more than 20 kW/kg, making some four times as much power as a similarly sized permanent magnet motor.
Å andra sidan så ger ju fossilmotorn i Koeniggseggs Gemera 600 hk och väger 17 kg enligt inslaget i Topgear där Christian v K själv intervjuas. 3 cyl och 2 liter.
Antagligen utan extragrejor som generator osv men ändå. Hade Freevalve-teknologin kommit 10 år tidigare så hade avgasmotorerna sett annorlunda ut.
