Romain Grosjean suggests Formula 1 should shake up the calendar every year following the success of this year's new additions.

Due to Covid-19, F1 was forced into a predominantly European-based season in 2020, excluding this weekend's trip to the Asian side of Istanbul in Turkey and the season-ending tripleheader in the Middle East.

That change saw five circuits included that were not part of the original schedule, and Grosjean admits he has enjoyed the chance to race at different venues.

“Yes, very much," he told the Haas website.

"First, it was a very good job by Formula 1 managing to get so many races into the season, second, it was really cool to discover, or re-discover some tracks like Mugello, Nürburgring, Portimao, Imola, and I think Turkey’s going to be mega.

“To me, they are tracks that should be on the calendar. I know we cannot go to 30 races a year, but I would love to see a change from year to year in terms of the tracks Formula 1 visits.

"It’s really cool to discover new places and see the different types of racing."

Grosjean also thinks shaking up the calendar provides an opportunity to create better races, with teams and drivers having to learn and adapt.

“I guess it’s not easy. There are a few tracks, like Barcelona, where you don’t really need the Friday as you know it by heart, but Imola – well I raced there a very long time ago, so I didn’t really remember it that well,” he explained.

"I think it’s quite exciting. It brings some unpredictability into the race – that’s something Formula 1 has been generally lacking so hopefully, it will spice things up.”

At the same time, the Frenchman, who is set to leave F1 at the end of this year, admitted sadness at not getting one more race at some cancelled circuits.

“Suzuka, as it’s my favourite track, that’s the one I’m definitely missing” he revealed.

“I’d include Singapore, it’s always quite an iconic one. Austin’s a pretty good place. There are many tracks I’m disappointed we didn’t get to.

"That’s why seeing a calendar that maybe one year is more European based, the other year at newer circuits, it could be quite cool. Then you get the best of both worlds.”
