If you mean from "stock" content, yes but they mostly are clones with different names from the ISI days, and some (maybe most?) are 3PA tracks:But is there proper Ovals in rF2?
Daytona ("Jacksonville", it's not an exact copy but close)
Talladega ("Alabama Superspeedway")
Charlotte ("Mountain Peak")
Fontana/California/Auto Club Speedway ("Apple Valley")
Homestead ("Palm Springs")
Kansas, I think... ("Eagle Creek")
I haven't driven them in quite a while but remember thinking most of them were pretty good, but I never liked Eagle Creek - that one always felt sub-par compared to the others. And I remember some frustrating AI issues at Indy (crashing in turn 2 ALL THE TIME). But it's been a while so maybe it's better (or not). There are also of course plenty of mod oval tracks out there. Sounds like a good time to revisit the RF2 stock cars - and don't fear trying them on road courses. In the tuning screen (before you hit the "Race" button and go to the track) there is a Road Course configuration you can select to start you in a default road course setup.
I'd say just forget about how fast it is vs other car types, that's not really going to affect how fun it is or how good of a race it produces. They are relatively low tech, low downforce, big heavy powerful brutes but there's still plenty of room for finesse and skill to drive them well.
