Race speeds vs qualifying speeds

Race-day averages always trail qualifying speeds, often by 40–50 mph. Qualifying is a flat-out four-lap attempt on a clear track with maximum boost and minimum downforce; the race is run with fuel for stints, dirty air in traffic, and caution-period laps that drag the average down.

A typical pole speed sits in the 226–234 mph range. A typical race average sits in the 165–185 mph range — only Tony Kanaan's 2013 winning average has cleared 187 mph in the modern era.
