Maria said: "This is a really special day for me. I have had the privilege to be associated with some of the best brands in the world, but now to be partners with Porsche, is such an amazing honor"
Porsche CEO, Matthias Meuller said: "Maria Sharapova is an exceptional athlete. She combines top performance in her sports with elegance and power. These are precisely the qualities that are embroiled in our sports cars."
