WILL A FOCUS ELECTRIC TOW ON A TOW DOLLY WITH FRONT WHEELS ON DOLLY?? IF SO WHAT ARE THE PRECAUTIONS?? TOWING FROM NEW YORK TO GEORGIA
EVA said:DO NOT TOW YOUR VEHICLE WITH ANY WHEELS ON THE GROUND, AS VEHICLE OR TRANSMISSION DAMAGE MAY OCCUR. IT IS RECOMMENDED TO TOW YOUR VEHICLE WITH ALL FOUR (4) WHEELS OFF THE GROUND SUCH AS WHEN USING A CAR-HAULING TRAILER. OTHERWISE, NO RECREATIONAL TOWING IS PERMITTED.
"Regenerative braking" is just terminology, and occurs through the motor being turned as a generator (driven by the car's forward motion). It has nothing to do with the mechanical friction brakes, which are on all four wheels.unplugged said:There is no explanation as to why the rear wheels shouldn't touch the ground when towed. The only thing I can think of is the regenerative brakes and assorted hardware on each wheel. In any case, I wouldn't even risk it in an emergency.
Okay, I can think of a few reasons...WattsUp said:I cannot think of a good technical reason why the car could not be towed, even long distances, on the rear wheels. It should just be like any other front-wheel drive car... if all the friction brakes are disengaged, then the rear wheels are free-turning.
I have tried to learn a bit about regenerative brakes, and I don't think the answer is quite as simple as you describe. http://auto.howstuffworks.com/auto-parts/brakes/brake-types/regenerative-braking.htm (Which really doesn't answer the physical mechanical part of the equation.) Here is an article a bit more descriptive on the mechanics needed, http://alternativefuels.about.com/od/hybridvehicles/a/regenbraking.htmWattsUp said:The rear wheels are not connected to the motor, so I cannot think of a good technical reason why the car could not be towed, even long distances, on the rear wheels.

The information you read is generally correct. But, in the FFE, only the front wheels are connected to the drive-train. The rear wheels are not connected to the drive-train in any way and, as such, they do not participate in regenerative braking.unplugged said:There has to be some type of motor or mechanical connection from the wheels to the motor in order to charge the battery. I'm am really a novice on this, but to me common sense would dictate that the rear (and front) wheel hubs have to be designed differently in order to transfer energy to the motor.WattsUp said:The rear wheels are not connected to the motor, so I cannot think of a good technical reason why the car could not be towed, even long distances, on the rear wheels.

Yes, I finally figured it out before I went back to here: There is no regen on the rear. The front motor does all the work.WattsUp said:Regenerative braking is an aspect of the drive-train, not the brakes or wheels. The FFE is a two-wheel drive car, and a two-wheel regenerative braking EV.
