Let the 2015 Formula One World Championship begin!
All members of the Sauber F1 Team worked very hard towards one goal: to get the Sauber C34-Ferrari on the race track and make it as reliable and fast as possible!
We did it! Pre-season testing already proved our race car’s reliability. It’s speed will be tested during the Formula 1 Grands Prix around the world.
This video is a THANK YOU to everyone back home at the factory in Hinwil, Switzerland. A THANK YOU to the members of our race team. A THANK YOU to our many fans around the globe. And a THANK YOU to our team partners.
We couldn’t do this without the amazing support of you all!
