Formula 1 isn't a sport, it's a war. Every year, teams bankroll extensive research and development projects to prove their mettle in the annual arms race; hundreds of thousands of dollars are sunk into each aerodynamic appendage, piston ring or splash of fuel to find an advantage worth fractions of a second.
With 2019's slight rehash of the regulations, the focus shifted - and teams had to very quickly get on top of extracting every last drop of performance from the bargeboards. Now, terms such as "boomerangs" and "serrations" have entered the F1 lexicon, having previously been restricted to throwing objects and bread knives respectively.
Although the summer break - and mandatory shutdown - enforced a two-week truce between F1's fiercest competitors, that has now come to an end as the Belgian Grand Prix looms on the calendar.
