Today, Infiniti ->ke36 and Red Bull unveiled the fourth and final video of their web series that helps us understand how a Formula 1 car is built. After learning about the design, the composites and the manufacturing process, the fourth episode shows us how the build of the car itself takes place in the assembly bays of Milton Keynes HQ.
