Generally the software and ecus/ operating systems are the same ggoosen. . Most of the underlying parts of mini are bmw. That's how manufacturers make money. One product suits all. Hence the I drive seats etc. Cosmetically different but under the skin the mini and bmw active tourer are similar etc etc. The i8 has a retuned Cooper engine.Hence minis are expected to behave in the same genetically linked way as their bmw cousins! And they do!
