A Mercedes chief has admitted his "surprise" that none of their Formula 1 rivals found the loophole in the rules which enabled them to use their unique sidepod design last year.
By their usually lofty standards, Mercedes' 2022 car was a dud. The W13 was uncompetitive compared to the machines produced by Red Bull and Ferrari and it left the Silver Arrows unable to compete for the titles.
They did catch eyes up and down the paddock, though, when they turned up with a car with radically different sidepods compared to the rest of their competitors. The 'zeropod' design gave the W13 a distinct shape and was a much-talked about innovation in the early stages of the season.
