The Bolt and Leaf are Front Wheel Drive (FWD) and the Model 3 is cheaper than the Bolt at least. Everyone presumes that the Model 3 will be Rear Wheel Drive (RWD) like the Model S started out as. Also, Elon has said this car will compete with the 3 series BMW that is RWD. I predict it will be FWD with a D option for those that want more horsepower. The econobox segment that the low-end Model 3 is targeting is all FWD.
