Siemens has developed a 50kg electric motor that can produce 260kW at 2,500rpm – slow enough to drive a propeller without a gear box.
Click to expand...

For the Americans: 50kg = 110lb and 260kW = 350hp.

There is still the weight of the batteries to consider... Perhaps that's why the company said: "..the electric motor is relatively powerful, quite racy for a four-seater aircraft..." With 350hp I would be thinking six-seater (Piper Malibu) but if you've got to dedicate 100-or-so of that horsepower to lugging around batteries then perhaps the mathematics will be different in the electric age.
