That's why, on the day of 22 November last year, he climbed into the Aston Martin AMR22 and asked his new engineer: "How many kilometres does this engine have? After a quick check by the technician, the racer heard in his headphones that about 6,000, the equivalent of about seven Grand Prix races with their corresponding training sessions. The Oviedo rider then suggested that he be fitted with one with less use; the engineer replied that it wouldn't be necessary, that the one he had purring behind his back was fine. The two-time champion wrinkled his nose and went out onto the track not entirely convinced, however, the used propellant did not falter at any time nor did it show any signs of doing so. That was the main reason for Alonso's sincere satisfaction as he stepped out of his new car: an unexpected reliability he had not enjoyed for years. The Renault engines he used in his final year at McLaren (2018) and the last two seasons in an Alpine were starting to show signs of fatigue after 2,000 kilometres. If we assume that during a full weekend with free practice on Friday, timed practice on Saturday and race on Sunday, an average of 800 kms is covered, it can be said that these engines barely made it to their fourth race alive. It seems that these engines were overheating, and Alonso noticed signs of this from one lap to the next when he noticed a drop in performance for no apparent reason, heralding a major failure in the immediate aftermath. In this way, the Oviedo driver used up to six engines in 2022.
