But it makes impressive sounding advertising copy so it's what we get stuck with...
In theory, the lower the impedance, (AC resistance) the more current the motor could pull at a given voltage, and amps make torque. Since our controllers limit the current by dropping the effective voltage sent to the motors, this means the more efficient motor gets sent a lower voltage per Ohm's law... The motor comp figure also includes the resistance of all the cables and connectors, (which will be higher than the motor impedance, so tend to swamp it) and is also a conservative value, so most of the time the value will be pretty much the same, with the biggest difference being whether it is a 2-brush or 4-brush motor.
Assuming the motors are physically interchangeable and priced about the same, I'd go for the higher watt rating on general principles, but I'm not sure there is a lot of practical difference.

i was looking that over a while back myself - but i noticed they both had 800watt motors - i may be mistaken - i compared both chairs spec side by side
i could be wrong - - either way they say you can easily change out the street 3 inch tires to the off road ATV tire - all you need is there spacer -

they both show 800 watt motors - nothing about an upgrade -
look at both RWD models - the model you show is a MWD or FWD - its not a RWD -

from the looks of the picture - with the motors - i dont even think you would feel any difference between 650 and 800 motor

In soft beach sand the bigger motors also help you navigate easier with out getting stuck as easy
the specs - it says 6.2 then in other specs of the same chair - shows 6.5
maybe all the same motors but wont be the same speed - maybe 6.2 and 6.5 may be the same - which one - slower or faster one ?
should all be 6.5mph standard - then options for slower 5.5 - or 5mph and should offer an 8 mph
let the user decide what works best for them - legal limit is 8.5 - sunrise does it - bounder also now -

i am sorry i went off course here - this was about the Frontier motors
thats the new chair here and they now show 8 mph instead of 8.5 they shown before on my chair - and get this - now if you get a seat lift - you cant get 8mph motors -
