Eventually, it will be trickled down to lesser models of Maserati’s revamped lineup where it will be seen in a tuned-down form. As per some international reports, it will be produce 542 PS in the sports cars and 523 PS in the SUVs. After the MC20 supercar, it will be also be featured in the Levante by 2021.

In 2021, the next-generation GranTurismo will be introduced along with the Maserati’s second SUV and an “all-new sportscar cabrio," the latter might be a droptop MC20. A year later, the company will introduce the GranCabrio and Quattroporte replacements, followed by the next-gen Levante in 2023.
