Six-time Formula One champion Lewis Hamilton believes new rules in place for the 2021 season onward could give the racing series its best era for a long time.

The 34-year-old Mercedes driver, who was speaking ahead of this weekend’s Brazilian Grand Prix, hopes the rule changes will enable him to test his abilities further in a more closely competitive racing environment.

F1 announced its new rules for 2021 during the U.S. GP late last month, in which Hamilton secured his sixth title to move one behind Michael Schumacher’s all-time F1 record.

F1 owners want closer racing and budget caps to reduce the financial gap between traditional big spenders like Ferrari, Red Bull and Mercedes compared to more modest teams.

Cars will be heavier and slower, too, wheel-to-wheel racing is set to be improved, and the calendar could be expanded from 21 to 25 races — although drivers are not in unanimous agreement on more races.

Hamilton added that the 2021 F1 cars look somewhat strange, but the British driver supports changes that bring more excitement for fans.

The Brazilian GP takes place Sunday at Interlagos in Sao Paulo and is the penultimate race of the season.
