I wonder how much leeway the teams will get for playing with details. For example, the curved device on the outside of the front wing endplate and the exact size and positioning of the front wing slot gaps that wrap around under the endplate will be quite useful for tuning the aero around the front tyre and its wake.
Other than the weird wheel "hub caps", it appears to be basically the car that was revealed two years ago but with a coat of paint thrown over it. So much for a big "reveal".
If you are more fortunate than others, build a larger table not a taller fence.
