The Porsche Cayenne's new electric model hasn't yet been revealed, but we got a chance to drive prototypes of all three variants—base, S, and Turbo—in Spain. Remember when the Porsche Cayenne had a two-speed transfer case? The Electric model doesn't have one, or any locking differentials, but the torque of the electric motors and the brake-based interventions make the Cayenne EV plenty off-road capable. The Cayenne EV will launch in three flavors: base, S, and Turbo.
