The FIA has announced that from 2014, the stepped-nose cars we see today will be banned. The change is to the maximum height of the rest of the car's nose, which will now be in line with the maximum height of the rest of the nose.
I did think that the vanity panel was an improvement over last year; we'll have to see what the 2014 cars end up looking like with the new rules.
Also for 2014, engine manufacturers will have to provide the same package to their customer teams that they provide to their factory teams; and the rules surrounding blown exhaust have been tightened.
