<\/p>\nFormula 1\u2019s first Bahrain test has highlighted a topic that will be discussed in the F1 Commission\u2019s next meeting: race starts. The new power units are making those more difficult, as engines need to rev very high for an extended period of time in order to get the turbo in the right window.<\/p>\n
The issue has reached a point where teams are requesting regulatory intervention ahead of the season-opening Australian Grand Prix.<\/p>\n
In the past, as drivers prepared for the race start, the MGU-H assisted the turbo in quickly reaching the necessary pressure for a good acceleration. It played a threefold role \u2013 helping the turbo enter its operating window, reducing the required time to do so and, above all, doing so without burdening the internal combustion engine.<\/p>\n
Without the MGU-H, there no longer is an external generator to provide energy to accelerate the turbo, which falls to the internal combustion engine. The latter must now run at much higher revs, for longer, to reach the required parameters for a decent getaway.<\/p>\n

During practice starts in Bahrain, drivers were seen revving during up to 10 seconds, sometimes more, before the actual launch. This is a common trend, though it will depend on the experiments teams are conducting to fine-tune procedures. Significant variations were observed between practice starts from the same drivers, with engineers attempting to understand how much revving is ideal to help the turbo \u2013 which clearly is suboptimal for the internal combustion engine.<\/p>\n
Looking at the data from Sakhir, peaks of over 13,000rpm were recorded, as in Andrea Kimi Antonelli<\/a>\u2019s final practice start at the end of day three. This is an extreme case, but cars tend to stabilize just above 12,000rpm on average. For reference, these are values that the previous power units only reached during moments of maximum effort \u2013 certainly not at the start.<\/p>\n In past years, thanks to the MGU-H, the values were significantly lower: the average fluctuated between 9,000rpm and 10,000rpm depending on engine manufacturers. For this reason, a pre-established interval is being proposed among other ideas.<\/p>\n Andrea Kimi Antonelli, Mercedes telemetry<\/p>\n Photo by: Gianluca D’Alessandro<\/p>\n This topic rarely arose in the past, precisely due to the hybrid element\u2019s support. The current technical regulations prohibit using the MGU-K to release energy when the car is stationary on the grid, except for specific reliability reasons. The electric motor cannot be used below 50km\/h, which makes the preparation as well as the launch even trickier.<\/p>\n One option would be allowing the MGU-K to be used during the start, but that precious energy would then be wasted on supporting the turbo and lead to struggles on the first few straights.<\/p>\n \u201cThe difference between a good and bad start last year was you got a bit of wheelspin or you had a bad reaction time, whereas this year it could be effectively like an F2 race where you almost go into anti-stall or something,\u201d McLaren<\/a>\u2019s\u00a0Oscar Piastri<\/a> explained. \u201cYou’re not just losing five metres or so, you could be losing six or seven spots if it goes wrong.\u201d<\/p>\n Oscar Piastri, McLaren<\/p>\n Foto di: Guido De Bortoli \/ LAT Images via Getty Images<\/p>\n For now, teams are working within their pre-established windows, but the system will need to be ready when the lights actually go out.<\/p>\n \u201cAt the moment, we’re just sort of going through our procedure, and I’m only doing my launch when I’m in a given\u00a0window,\u201d Mercedes<\/a>\u2019 George Russell<\/a> added. \u201cBut we are very conscious that for a race start, you go when the lights are out, you don’t go when your specific turbo is in the right\u00a0window.\u201d<\/p>\n Furthermore, gear ratios will change this year, with drivers having to use shorter gears through corners to recharge the battery while reducing turbo lag, even if it leads to higher fuel consumption. In Bahrain, very different approaches were seen among the engine manufacturers.<\/p>\n Read Also:<\/p>\n![\"Andrea](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/02\/1771179489_545_andrea-kimi-antonelli-mercedes.jpg\")
