Aston Martin have caused the first red flag of pre-season testing in Bahrain, with Lance Stroll's car having scattered the remains of a loose aerodynamic rake across the track. The session was halted 45 minutes into the four-hour afternoon session, with the remains of the broken rake needing to be retrieved from the asphalt by stewards. That saw all cars on track head back to the garages while the debris, left on the racing line between Turn 13 and Turn 14, was cleared.
What are aerodynamic rakes used for?
During pre-season testing, multiple teams sport aerodynamic rakes that look like scaffolding structures bolted to the top of the cars. The rakes contain dozens of small 'pitot tubes' that record data as to how the air flows over or around the car. That helps teams to better understand how their car is moving through the air, a particularly crucial tool amid F1's regulation overhaul for 2022.
