Aston Martin driver Sebastian Vettel and Alpine racer Esteban Ocon will start today's British Grand Prix with a fresh internal combustion engine mounted into their cars which will see them start using their last fresh engine allowed for the 2021 F1 season.
For the British Grand Prix, Aston Martin decided to install a fresh internal combustion engine into the car of Sebastian Vettel with Alpine having done the same with Esteban Ocon's A521 for the Silverstone round. The decision saw both drivers join George Russell in using their last fresh engine for the current season.
They can obviously use their previous two units should their first two engines be in a good shape. With 13 further races expected, it will be a difficult task for these drivers to complete the remainder of the season without any new engines which would result in a grid-drop penalty. Drivers ideally start using their third and last fresh engine at either the Belgian or the Italian Grand Prix, or this could be the Dutch Grand Prix this season that has been slotted in between the Spa and the Monza round.
Vettel and Ocon are using a fresh turbocharger, MGU-H as well with the Frenchman having also received a new MGU-K.
Williams' Canadian racer Nicholas Latifi has received a brand-new energy store and control electronics for the tenth event of the 2021 F1 season.
For the 2021 FIA Formula One World Championship, exhaust systems have been added to the list of limited-use components, with each driver allowed no more than eight per season.Power unit components used ahead of the British Grand Prix:
Should a driver exceed that limit, grid penalties will apply, just as with engines (ICE) (three per season), motor generator units-heat (MGU-H) (three), turbochargers (TC) (three), energy stores (ES) (two), control electronics (CE) (two), and motor generator units-kinetic (MGU-K) (three).
Six drivers will race today with a fresh exhaust system this weekend with Vettel, Charles Leclerc, Carlos Sainz, Kimi Räikkönen, Antonio Giovinazzi and Ocon having access to a fresh unit at Silverstone. The situation is getting critical for the Frenchman with Ocon having started to use his sixth of the eight new exhaust systems allowed for the 2021 Championship season
No driver will start the tenth Event of the 2021 Formula One World Championship with a new gearbox.
