F1's Quietest Champion Just Changed the Sport

The technical change, explained

The new floor regulations close the specific aerodynamic loophole that the dominant team exploited so effectively last year. The change is small on paper. In wind-tunnel terms, it is significant. In lap-time terms, it should bring the field closer by something on the order of two-tenths.

That two-tenths is a season's worth of championship points if every other variable holds.
