Still aluminium...

Also, during the test Lowe confirmed the gearbox was still an aluminium casing. It was speculated in the carís launch analysis, that the casing might have moved to a carbon outer case, but this isnít the plan this year. Instead the aluminium case will remain for at least 2018, Lowe adding ďa carbon case isnít necessary to be competitive in F1Ē, while the pressures of weight saving to get down to the minimum weight limit, may be aided by the structural efficiency of carbon. An aluminium case is certainly possible to be either as light or strong as a carbon case, but not both. Its noteworthy that aluminium loses strength at higher temperatures, remembering also that the gearcase houses not only the hot gear cluster, but also the exhaust turbine for the turbocharger. Williams have had a number of inboard suspension failures over recent years, other F1 designers have speculated that they and other handling issues suffered by Williams, are attributable to the aluminium case. As Williams remain the only team to run a metal casing, with Renault being the only other team up until this year, albeit they ran a stronger titanium case.
