CHARLOTTE, N.C. (AP) Moving swiftly to address driver safety concerns, NASCAR on Tuesday banned cool-down laps and will start allowing teams to hook up cooling units to their engines on pit road - the first major changes to the popular new knockout qualifying format unveiled this season.
The decisions were made during a conference call with crew chiefs. Several people who participated told The Associated Press that NASCAR initially said teams could use external fans on pit road to cool the engines. But after nearly unanimous objection, NASCAR relented on the use of cooling units.
NASCAR this season moved to the knockout format that has been widely praised as more entertaining. Drivers, however, were barred from cooling their engines on pit road because using the cooling units would mean opening the hood - and once hoods are open, NASCAR inspectors would have too difficult a time policing the pits to make sure adjustments were not being made.
