NASCAR announced that its 2013 NASCAR Sprint Cup Series car will feature some tweaks to their appearance aimed at helping fan recognition and in maintaining manufacturers' unique identites. Chief among them will the driver's last name being featured on the windshield, in the manner of the old International Race of Champions. Among other changes:
- Sponsor decals will not be permitted on the headlights and taillights, two key distinguishing characteristics of the auto manufacturers' brand;
- Car numbers will be moved from the lights to the front and rear bumpers;
- A single sponsor logo will be permitted on the roof under the number;
- Team sponsor decals will be permitted to extend past the front edge of the b-post;
- "Step and repeat" / background patterns will be permitted on the sides of the car;
- Due to the slightly smaller car, the car number will be reduced by 10% and the contingency decals will be reduced to 26 square inches.
"These changes are an extension of the unprecedented collaboration with the auto manufacturers on the 2013 car, great industry feedback and our focus on increasing fan affinity as part of NASCAR's Industry Action Plan," said Steve O'Donnell, NASCAR senior vp of racing operations, who introduced the new design.
