Formula One technical director Ross Brawn believes the sprint qualifying race at the Sao Paulo Grand Prix was the best yet ahead of an expansion of the format in 2022.
A dramatic race weekend in Brazil saw Max Verstappen top qualifying on Friday, Valtteri Bottas win the sprint event to claim pole position on Saturday, before Lewis Hamilton triumphed in a thrilling main event on Sunday.
Hamilton had started the sprint at the back of the grid and charged all the way up to fifth to improve his grid position for the main race, which he ultimately battled to win from 10th after a grid penalty.
His move up the field was the highlight of an entertaining sprint that had more fireworks than the previous two held in 2021 at Monza and Silverstone.
The sprint schedule also leads to more meaningful action on the Friday, when qualifying takes place rather than the normal practice sessions.
"Saturday's F1 Sprint was, in my view, the best one of the three," Brawn wrote in his column for the F1 website. "It had plenty of action, with loads of battles – including Lewis carving his way through the field.
"It was a great Saturday afternoon of entertainment, an appetiser for the main course on Sunday.
"We had a fabulous Friday, too, with a dramatic qualifying session. It can never be underestimated how much of an impact the Sprint has on a Friday.
"With only one hour of practice, it creates some jeopardy heading into the rest of the weekend, as the teams are not as prepared as they can be."
Brawn has previously revealed F1 plans to double the number of sprint race weekends to six in 2022 and are pondering some small but significant changes.
Presently points are only awarded to the top three drivers in the sprint but that could be increased to the top 10 to align with the main race and encourage more daring overtakes further down the field.
New cars that promote overtaking are already coming in for next year, while Brawn has accepted that the formal award of pole position should come after Friday qualifying rather than for the Saturday sprint.
He added on Wednesday: "We think the foundations are very strong for the Sprint and will be presenting more details of our plans for six events in 2022 in the coming weeks in discussions with the FIA and the teams.
"There are things we need to tweak but Brazil showed the Sprint is a great addition to the weekend.
"It has made Friday, Saturday and Sunday big moments that are exciting for all of us."
There are three races to go in the F1 season, with Verstappen leading Hamilton by 14 points going into the inaugural Qatar Grand Prix this week, with the constructors' championship also finely poised.
"We're seeing a titanic battle for this year's two championships," added Brawn.
"The race in Brazil was just another twist in an engrossing tale. It’s been fantastic. No one knows what will happen next.
"We have got two new venues to visit in Qatar and Saudi Arabia, before heading to the finale in Abu Dhabi where the circuit has had a series of modifications. The stage is set."
