When will the Next Gen car debut?
2021

Will the cars all look the same?
NASCAR would like for the cars to have more of a street car look with unique manufacturer characteristics.

Will a new engine debut at the same time?
No. New engines are not likely until 2023.

Why a new car?
NASCAR is trying to limit the cost of competing in the sport for teams, sponsors, and manufacturers.

Will the new car attract new manufacturers to the sport?
That is NASCAR’s plan However, a new manufacturer would not be expected to join the series until the new engine debuts.

Possible new manufacturers would include: Honda, Hyundai, BMW, Mercedes-Benz and Volkswagen.

Will the car have 18″ wheels?
Yes.

Will NASCAR use a single lug nut?
Bob Pockrass says that’s likely and it’s because of the loads on the larger wheels.

Will NASCAR use a spec chassis?
That is likely. NASCAR is still working to determine what parts of the car will use a common supplier.

Will the car be a hybrid?

Will the car have independent rear suspension?
All indications are that it will.  That will change the handling of the cars from the current version.

What about pit crew changes?
There is expected to be a refueling hose, rather than gas cylinder.

What about the transmission?
The H-pattern manual transmission will be replaced by a sequential transmission, likely a six-speed.
