F1 returns following an enforced five-week break with the Miami Grand Prix at the beginning of May
Formula 1 has made a series of rule changes to address concerns about the new engine regulations that were introduced for this season.
The amount of energy management required with the new power-units, which have a near 50-50 split between internal combustion and electrical power, has led to complaints from the drivers that their skills were being diminished.
Four-time world champion Max Verstappen has gone as far as to say that he is considering his future in F1 as a result of his dissatisfaction with the new cars.
The changes amout to a swathe of modifications to the way the engines operate aimed at allowing drivers to push to the limit in qualifying and reduce the risk of large speed differentials in races between cars deploying the full power of their engine and battery and those with no charge - a difference of 470bhp.
