NASCAR told teams Wednesday that the sanctioning body will use a superspeedway qualifying format at next weekend’s Sprint Cup and Xfinity Series events at Indianapolis Motor Speedway. The same superspeedway qualifying format will also be used at Michigan International Speedway in August.
The change comes in response to changes in the rules packages that will result in high-drag aerodynamics at both the 2.5 mile Indy track and the 2-mile Michigan Speedway. NASCAR announced last week the new rules packages that are in effect for several upcoming races on the NASCAR Sprint Cup schedule. After announcing several weeks ago that a new rules package will be used last weekend at Kentucky Speedway, new rules packages will now be used at Darlington Raceway in September, and both Indianapolis Motor Speedway later this month and Michigan International Speedway in August. Richmond, the race that will set the field for the 2015 Chase for the Sprint Cup, won’t have a new rules package but will have a new tire.
For Last Saturday’s Kentucky race a new low downforce rules package was used. MORE>>>
