McLaren not using Petrobras to start 2019 F1 season

McLaren is not yet using Petrobras fuel after delaying a complete switch to its new Formula 1 technical partner it had planned for the start of the season.

McLaren not using Petrobras to start 2019 F1 season

The team admitted last month it may delay using products from the Brazilian company, having struck a deal in February last year to change from BP/Castrol for 2019.

It is understood to be using Petrobras lubricants in the transmission but has not started the campaign using its other products, like fuel or engine oil.

“It’s still a work in progress,” said McLaren F1 CEO Zak Brown when asked by Motorsport.com about using Petrobras products.

“It’s not currently in the car but we anticipate it being in the car soon.”

Fuel and lubricant suppliers have developed into even more of a performance differentiator in the V6 turbo-hybrid engine era.

Ferrari has continued its long-term partnership with Shell, Mercedes has had a collaboration with Petronas through its run of five consecutive drivers' and constructors' titles, while Renault uses BP/Castrol and Honda is partnered with ExxonMobil.

That means using a different company to the works Renault team, and having its own exclusive arrangement, presents an opportunity for McLaren to find a technical edge.

However, it is a complex process that is made tougher by the need for Renault to find dyno time to test whatever products Petrobras come up with, given it has its own supplier to work with.

Brown’s indication that McLaren wants to make the switch “soon” suggests the team intends to switch products mid-season.

There is nothing stopping the outfit from doing so, and at the team’s launch of its 2019 car last month sporting director Gil de Ferran said: "When we make our plans we take all those difficulties into account to make sure we can execute them properly."

The Mercedes lap that puts F1 victory fight back on a knife-edge

Red Bull led the way after the first two practice sessions for the 2021 French Grand Prix, but only just ahead of Mercedes. There was all the usual practice skulduggery complicating the performance picture, but one aspect seen at the world champion squad gave it a ‘surprise’ lift, as it looks to leave its street-circuit struggles firmly in the past.

After its worst campaign in 40 years, the famous Italian team had to bounce back in 2021 – and it appears to be delivering. Although it concedes the pole positions in Monaco and Baku paint a somewhat misleading picture of its competitiveness, the team is heading into the 2022 rules revamp on much stronger footing to go for wins again

OPINION: An interloper squad got amongst the title contenders during Formula 1’s street-circuit mini-break, where Red Bull left with the points lead in both championships. But, as the campaign heads back to purpose-built venues once again, how the drivers of the two top teams compare in one crucial area will be a major factor in deciding which squad stays in or retakes the top spot

The newspapers, naturally, lingered over Max Mosley’s tainted family history and niche sexual practices. But this is to trivialise the legacy of a big beast of motor racing politics. Stuart Codling weighs the life of a man whose work for safety on both road and track has saved hundreds of thousands of lives, but whose penchant for cruelty remains problematic and polarising.
