For anyone who's interested, it seems that new ships do indeed have a symbol next to them to differentiate in the record tables
Although, not while you're doing it at the end of your race, but in the menu tables.
I would say though, from what I've seen of the new ships, they are 'butters' to look at from the back. Funky MOFOs from every angle, except the one we have to spend most time looking at them from. They're like floating lego bricks. Weird!
EDIT: Thanks Paul. I already gave in and downloaded it, but was a bit too late with the message
Is that an F though? It looks more like the Anulpha Pass symbol or something similar.
EDIT: Never mind, I can kind of see it now, after much squinting
