The Dry Autocross is presented by:

The autocross has been extremely popular the last couple of years, and has gotten to the point where long wait times and traffic jams have become very common. In order to alleviate both, we're creating three classes for autocross, and scheduling times when these classes can make runs on the autocross course. Cars will be split into two classes, Domestic and Domestic powered, and Import. Domestic class is reserved for vehicles built by the domestic manufacturers such as GM, Ford, Chrysler, AMC, etc. Imports are vehicles such as Toyota, Honda, Subaru, etc. Imports that are powered by domestic-sourced engines (V8-powered Miatas, for example) can run in the domestic class. Additionally, autocross awards will be presented for the Domestic class only.
Classes:
Class 1: Domestic Vehicles - includes import vehicles with transplanted domestic engines
Since the YearOne Experience is geared primarily toward domestic performance vehicles, we're creating two groups for these cars. Group 1 is for 1981-and-earlier models, while Group 2 is for 1982-and-later models. All kit cars (Cobras, Ultimas, etc.) must run in Group 2 (1982-and-later models).
Class 2: Import Vehicles
Imports are vehicles such as Toyota, Honda, Subaru, etc.
