F1, Ferrari: ERS technique decisive for SF-24 traction at Circuit Gilles-Villeneuve


Ferrari needs to win once more and why not straight away on the 4.361-kilometre Circuit Gilles-Villeneuve in Montreal, because the latest victory achieved by Charles Leclerc on the streets of Monaco in Monte Carlo has considerably boosted the Maranello crew’s morale. The Prancing Horse is now not afraid to take dangers and as an alternative adopts an aggressive method in each session. We clearly noticed this yesterday, when regardless of opposed climate circumstances, the 2 SF-24 automobiles confirmed no lack of braveness. Setting apart the formalities, let’s analyze some parts that will present the primary conclusions forward of the ultimate free apply session for the Canadian Grand Prix.

Let’s think about the telemetry of Charles Leclerc and Fernando Alonso of their quickest laps within the second free apply session in Montreal. Regardless of the difficult climate making the very monitor troublesome to guage, we are able to derive fascinating data from the telemetry knowledge. Let’s additionally make some preliminary observations earlier than the evaluation: Charles Leclerc achieved his quickest lap on medium tires with out utilizing the drag discount system, setting a lap time of 1.16.556, the fourth quickest time on the grid, +0.746 seconds behind Fernando Alonso. In moist circumstances, the tender compound utilized by Nando is actually extra environment friendly as a result of higher grip on a humid and ungrooved monitor.

Even with the usage of a more durable tire, Charles Leclerc demonstrates glorious traction and rear stability when exiting the quite a few chicanes on the monitor and the hairpin at flip 10. This may be famous primarily from the throttle knowledge: the Monegasque is all the time capable of go full-gas earlier when exiting the nook, gaining considerably within the first meters of the straights. This benefit is then misplaced when Fernando Alonso prompts DRS and Charles Leclerc doesn’t, dropping -15 kilometers per hour on the straight within the second sector and -27 kilometers per hour on the final straight.

As predicted, the SF-24 performs excellently on the curbs, as evidenced by how Charles Leclerc tackles the ultimate chicane: his braking enter is delayed by a couple of meters and is total shorter in comparison with Fernando’s (and all different drivers, analyzing all telemetry knowledge). Nonetheless, he can speed up on the similar second because the Spaniard. What issues within the ultimate chicane is chopping the curbs nicely to get the wheels on the bottom as shortly as doable, discovering the mandatory grip to enter the principle straight.

The 0.7 seconds hole is especially discovered on the straights and within the first sector, the place Leclerc doesn’t optimally sort out turns 1 and a pair of, dropping +0.2 seconds, primarily as a result of compound used, which doesn’t present good grip on the dampest a part of the monitor. He’s compelled to elevate his foot a lot sooner than the braking level and sacrifice the nook entry, to then discover a good burst of velocity exiting flip 2. All through the remainder of the lap, the Ferrari driver persistently has increased minimal cornering speeds in comparison with the Aston Martin driver and arrives on the exit of the hairpin with a spot of +0.140 seconds.

As quickly because the Spaniard opens the DRS, the delta clearly will increase to +0.746. One other affirmation of Ferrari’s agility and glorious mechanical grip might be seen from the telemetry knowledge that present the throttle and brake utilization percentages within the quickest laps of every driver. The upper the proportion of throttle utilization and the decrease the proportion of brake utilization, the extra grip the automotive generates within the quite a few chicanes and course adjustments on this stop-and-go circuit.

Another issues: we noticed a very good efficiency by Charles Leclerc, however be careful for Purple Bull, McLaren, and Mercedes. The W15 would possibly profit from this kind of monitor, which lacks technical high-downforce corners, probably hiding its flaws. The quite a few restarts with accelerations might favor it, noting from previous telemetry and micro-sectors how usually its energy unit (particularly at low temperatures) pushes strongly within the preliminary stretches. Moreover, Lewis Hamilton’s lap might have been a possible pole place if not for encountering Carlos Sainz’s visitors within the ultimate chicane, nullifying the 2 purple sectors he had set within the first and second sectors.

Sadly, there’s little to say about McLaren and Purple Bull, as the 2 drivers from the papaya-colored crew ran on medium tires at comparatively excessive occasions with out ever pushing, whereas Max Verstappen needed to keep within the pits for greater than half the session as a result of a mechanical downside with the ERS on his automotive (actually, from the telemetry of earlier laps, it was noticeable that the automotive was producing much less energy than anticipated).

Contemplating the knowledge included in our onboard evaluation of FP2, it confirms what was stated in regards to the vitality restoration technique, the place the Ferrari engineers determined to undertake the tactic used efficiently in Monte Carlo once more. This tactic permits spreading the height energy recovered from the 2 motor turbines, MGU-H and MGU-Ok, throughout acceleration phases, with the clear goal of offering the Ferrari SF-24 with a traction increase.
