For this, Porsche charges £104,190, which is almost £20,000 more than a 4S, but it points out that £17,000 of this is standard kit you would have to pay for on the 4S, such as adaptive dampers, torque vectoring, Sport Sound and, of course, the big battery. It comes with bespoke 20in rims, too (with 21in an option), and its own suspension tune.
