Default GE Beast 19hp @48v with 400amp controller

Found a dealer advertising this for the D394/D395 Beast.
19hp = 14174watts
14174/48v = 295amps
295/400 = 74% efficiency

Would not have thought it would be that efficient for that much hp.

What do ya'll think?

FWIW the dealer emailed saying at 19hp this motor is turning ~1800 rpm. Thats > 55 lb_ft of torque.

The dealer is playing game with numbers and quoting peak HP. The real continious HP @ 48 volts is 11.4 HP @ 2300 RPM. Here is the real dope on the motor

Yeah ~11hp is continious but with just a 400amp controller it puts out 19hp for a short burst if needed.
You link is to the dealer that emailed me.
Thanks
