It was all going on at Imola, so without further hesitation, here are five things we learned from a cracker of a race.
Verstappen versus Hamilton is no one-off
If there were any lingering doubts as to the title credentials of Red Bull and Max Verstappen, this grand prix laid those to rest.
After making an error on his final effort in qualifying, Verstappen was pushed back to the second row of the grid by team-mate Sergio Perez but after two corners, and one extremely ballsy move against Hamilton, the Dutchman had taken the lead.
McLaren and Ferrari are two of the most successful teams in F1 history but, in recent years, both teams have endured their own difficulties.
The last time either tasted success was 2008, with Ferrari claiming the constructors' crown and Hamilton the drivers' championship for McLaren.
Rather than battling for wins, the pair now appear to lead this year's 'fight for third', with Mercedes and Red Bull battling for the title.
In each of the two races so far, Lando Norris has led the four drivers, with his Imola podium allowing McLaren to pull a slender seven-point lead over the Scuderia.
Just like the title battle itself, this fight could go the distance.
Track limits are no joke
After the Bahrain GP and the questionable application of track limits regulations, FIA race director Michael Masi issued clear directions to the teams ahead of the weekend.
These instructions were altered on Saturday morning to allow extra room for error at turn nine, Piratella, but the clarifications remained clear and there were no complaints when Norris was stripped of a time that would have seen him qualify third.
The swift action of the FIA to address the track limits issue was welcome but pressure must be kept on the governing body to ensure standards remain high at the Portuguese GP and at all future events.
AlphaTauri errors cost points...again!
AlphaTauri stole the headlines in pre-season testing, setting the second-fastest time behind Verstappen's Red Bull but the opening two races of the year have failed to land the rewards the team expected.
In Bahrain, Pierre Gasly ruined his race by making early contact with Daniel Ricciardo's McLaren and limped home 17th with Yuki Tsunoda recovering from a poor qualifying to finish ninth.
At Imola, Tusunoda dropped out of the points after spinning into the gravel and Gasly took early pain after the AlphaTauri pit wall dithered to change the Frenchman off wet tyres despite dropping eight seconds per lap to those on intermediates.
As a result, AlphaTauri has just eight points from two races and sits fifth in the table, 26 points behind fourth-placed Ferrari. They know they can do better.
