dw, you've got that backwards. The more power you can put down to the track, the more drivetrain efficiency you have, think about it. Oneways will give more on-power and corner exit steering because the front is acting like a solid axle on power. This causes you to scrub much less speed than you would with a diff. Because you are srubbing less speed and putting all the power you feed from the motor to the drivetrain onto the track, you have a more efficient drivetrain. The motor is not wasting extra power trying to make up for scrubbed speed like it would with a diff in. Since the drivetrain is more efficient, it's a little easier on batteries
