Appendix A - Automobile Classes APPENDIX A - AUTOMOBILE CLASSES It is the intention of SCCA® to class all essentially identical vehicles from the same manufacturer (which differ only cosmetically or in nominal mar- quee designation) in the same class. If a version is omitted from the class listing, and is otherwise eligible for the category, then its classification be the same as the equivalent which is listed. Any car listed under a NOC classification is ineligible for National events. See section 13.0 for other eligibility requirements. To use the catch-alls at the end of the specific car classes in Appendix A, start from the last class in the category and work up the classes until a class is found. Such unclassified will not be eligible for Solo® National Tours or the Solo® National Championships. See the following page for vehicles which are excluded from the Street cat- egory. For Street Category vehicles, the vehicle manufacturer’s specifications shall be used for specific wheel diameter and maximum rim width speci- fications. Abbreviations: AWD...... All-wheel drive FWD...... Front wheel drive IRS...... Independent rear suspension N/A...... Normally aspirated (atmospheric) NOC...... Not otherwise classified RWD...... Rear wheel drive S/C...... Supercharged T...... Turbocharged V(n)...... (n) refers to number of engine cylinders in a “Vee” block (n)v...... (n) refers to number of engine intake and exhaust valves
