The ford mondeo (I think it was called the fusion in the US) was 'inspired' by the Aston Martin Rapide. This was at a time when Ford owned Aston Martin. Fisker and Porritt, who worked at tesla when the model S came out, also worked for Ford/Aston Martin.

It's not just me either. For example, here's a ten year old thread on the tesla forum which mentions it:
