Group E features four different subclasses:

• Category I: Vehicles comparable to Category I must comply with the homologation criteria of Group N, Group A or Group R and have at least 4 seats and their original structure must remain identifiable at any time.^[2]
• Category II-SH: Silhouette-type cars (Cars with the appearance of a large production car with 4 seats);
• Category II-SC: Sports cars (Two seater competition cars, open or closed, built especially for competition);
