Porsche will build a battery-electric hypercar envisioned as the heir to the 918 Spyder model (shown here). As Michael Steiner, Porsche Executive Board Member for Research, told Motor Trend in a recent interview, designing such a vehicle would take five years at best.
The main challenge is to develop new traction batteries offering a higher power storage density than the current designs. Porsche is already making such batteries and has test samples of the same standard size as those used in the Taycan. However, it will be at least two more years until these innovative cells are ready for mass use.
Steiner admitted that work hadn’t yet started on a hypercar that would replace the 918 Spyder, and that it would only start when the new battery cells are ready. Developing the rest will take another three or four years, hence, the five-year term mentioned above is an optimistic estimation.
