When the decision was made to shove Formula 1's technical overhaul and return to true ground-effect cars back a year, the suggestion was that 2021 would end up as something of a holding year. But, following the condensed pre-season testing at the Bahrain International Circuit, it seems that the mandated technical changes to the aerodynamics have actually thrown some of the teams a loop. Instead of the 2020 carbon copy that many had been wary of, testing suggested that 2021 may actually offer one of the closest-fought seasons in years.
The biggest changes involve the floor, and the introduction of a triangular exclusion zone ahead of the rear wheel to strip the cars of some of the aerodynamic tools that teams used to improve the underbody downforce. The slots along the floor's edge are gone, and the diffuser and the brake-duct winglets situated at the rear of the car have also been trimmed back to culminate in a suggested 10% downforce reduction.
Three points finishes from as many starts represents a decent opening innings on paper, but Daniel Ricciardo has endured a tough start to his McLaren career - only magnified his teammate's excellent form. Yet both he and the team have good reason to expect a turnaround soon.
OPINION: Going up against the dominant force of Mercedes and Lewis Hamilton was always going to demand the best from Red Bull and Max Verstappen. But after making a couple more errors during the Portuguese Grand Prix, the Dutch driver showed there's a small gap he still needs to close in the 2021 Formula 1 title fight.
Red Bull's Portuguese Grand Prix fortunes were decidedly second best to Mercedes', but the result skews the potential that the team had at Portimao. With a new set of updates, the team looks good going forward into the rest of 2021's spicy F1 competition
Just as he did in 2020, Lewis Hamilton had to come from behind to win the 2021 Portuguese Grand Prix. Only this time there were two rivals he had to pass, among the several challenges he had to overcome, on his way to securing a 97th grand prix victory
Lewis Hamilton topped the crucial FP2 session on Friday as F1 returned to Portugal, but his Mercedes team cannot be sure it has the edge on its Red Bull rivals. As cool temperatures and wind combine with the still-slippery surface to present drivers with quandaries over set-up and tyre warmup, there's still everything to play for come qualifying.
As a highly-rated Mercedes junior, George Russell is naturally billed as Lewis Hamilton's heir apparent where Britain's next Formula 1 champion is concerned. But he may face competition for that accolade from Lando Norris, fresh from a confidence-boosting run to third at Imola whose rise is being accelerated by his McLaren team’s revival
The news this week that F1 has green-lit 'sprint qualifying' races that will determine the grid for three grands prix in 2021 was met with a blend of excitement and scepticism. But before those in both camps can be vilified, F1 must first work out what its criteria is for success - and what will justify making them a more permanent fixture
