Are 'Dega and Daytona the only superspeedways on the NASCAR circuit

Yes they are. Also the only Super Speedways built that l know of.

Some considered Michigan, Pocono, Indianapolis, and California all as super speedways though.

But if you mean as tracks that are pure speed no braking. then yes Dega and Daytona only ones.

Don;t forget Indianapolis. All the other speedways are considered intermediate tracks that are just about 1.5 miles around

yeah

Technically no. There is also Fontana, Indy, Michigan, and Pocono. All of which are considered SS on the NSC circuit. But Dega and Daytona are the only ones where they run restrictor plates and where you see the classic pack racing that most people associate superspeedways with.

Yup

You got it

No.the technical definition of a superspeedway is any track one mile in length or longer, including road courses. Racers, however, refer to three types of oval tracks. Short tracks are under one mile, intermediate tracks are at least a mile but under two miles and superspeedways are two miles and longer. So under that definition, Michigan, California, Pocono, and Indianapolis would also be considered superspeedways.

Yes.

Do not forget Atlanta it is the fastest track that NASCAR runs at.

Nope.

nope,atl,texas,homestead,Lowe's,they are not in size,but they are in speed,these tracks and some more can achieve the same speed as dega&datonya,any track that is 1.1/2 mile and can carry the same speed as the rest kinda holds the same ratings as the big 2
