Couldn't agree more. Except the heavy part. If the exact same motor is wound for a lower rpm it will simply have more torque. This means better acceleration for the same weight (plus or minus a beer can).

Yes, fully agree, I am very hip to trannys and transfer cases in all their forms. However, the Talon sitting in the driveway has neither. But is IS free and just sitting there whispering in my ear each time I pass by...
The top speed with 5000 rpm is 105mph and with 6000 rpm is 125 mph. We will find out what it will do...
Don't forget they DO make larger tires.
Don't worry, the Talon (DSM) is just a motor/controller/battery test rig. If a component passes muster it will be potentially employed in the AWD race platform which will use a tranny/transfer unless it ends up dual motor/dual diff. But that is off-topic for this motor thread. I will post build threads when the time is right.
A direct differential drive is actually a good tester since almost every car out there is direct in 4th gear. This provides a somewhat comparable power/torque test condition among various different vehicles. (if you also consider tire radius, axle ratio, and vehicle weight/drag).
Under continuous high-mph conditions (Le Mans, Daytona, Mille-Miglia etc.) I am fairly confident the stock (55kw) Scott Drive would eat a stock 11" brushed motor (35kw) for lunch. However, once you get into highly-modded and race-prepped vehicles using dry ice, turbo cooling fans, and other advanced cooling methods, then all bets are off. The best prepped vehicle will win, regardless of design configuration.
