The Canon EOS 6D body is not really renown for its Autofocus System capabilities when compared to i.e. the Canon EOS 5D Mark III (Full Frame) / Canon EOS 7D Mark II (APS-C) - and globally Canon photographers are not too keen for its 4.5 fps continuous rate compared to 6 - 14 fps in most sport-orientated bodies.
I took the Canon EOS 6D on various tests (deliberately) paired with the Canon EF 70-300mm f4-5.6L IS USM lens for demonstrating the camera's 11-Point AF system capabilities at 4.5 frames per second.
If this was my only Canon EOS body, I would have no concern shooting motor sport and / or Birds in Flight - only change I would make is to replace the 70-300mm lens with my 400mm prime lens for Birds in Flight (for faster AF and the 100mm additional reach).
