My first time photographing anything moving. Any tips on how to make it look faster or nicer? (album and context in comments)

Hey everyone, I went out this weekend and took some pictures of my cousin who was racing and after about 500 pictures I ended up with around 60 usable ones. I won’t post all of them but (here)[https://imgur.com/a/WjvVjoV] is an album of 8 that I really like. For all of the moving ones I’m using a Canon 6D and the Canon 400mm f5.6, the pictures were taken at 100iso, between 1/80th and 1/125th of a second at I think f10. The last picture in the album is using the same camera but with the Canon 50mm f1.8, it’s the lens I use 99.9% of the time for pictures like [this](https://i.imgur.com/QZIkWGD.jpg where I expose for the sky so I can drop the highlights on then you can see the clouds and everything.

If anyone has any tips on how to make the cars feel faster and more dynamic that’d be awesome!
