I've long lost track of how many diffrent fisher-price motors we've had over the years. It seems that every year a new one is in the kit, and some years there have been multiple versions delivered. Worse still, diffrent versions can be visually hard to tell apart and still have very diffrent preformence. Part numbers can help, but even those are unreliable in the toy industry.
Fisher-price makes tens of thousands of these cars, and they buy whatever motor meets the design requirements at the time and is cheapest. Sometimes its a Johnson electric, sometimes its a Mubashi, sometimes it's who knows who else.
I can tell you that it has always been a 550 size can with a power output of around 100 watts at peak power. All have been 12 volts, with one notable exception (what a fun surprise a 400 watt 550 motor was while it lasted!).
In anycase, expect any motor you buy now to be the wrong one come January. If you want to use them for some other project, check ebay. Bane bots also has a good selection of 550 size motors and gearboxes, although none are an exact match for the FP.
It's a great motor. By far the highest power to weight ratio of any kit motor so far. If you can keep them running fast they'll last all season too.
