Porsche and Audi will share an electric car platform

Which cars come first and when depends on CO2 emissions requirements, Blume said. It won’t surprise you to hear why they’re sharing resources: money. Blume said it would cost about 30 percent more for each brand to develop their own EV platforms. It won’t be a trivial expense even then. Stadler estimated that it would require a “low single-digit billion euro sum” to develop the platform by 2025.
