The 2009 Hyundai Genesis’ six-speed automatic transmission is one smooth-shifting gearbox, but Hyundai’s not content to rest on its laurels. For 2010, Genesis V-8 models will be mated to an all-new eight-speed transmission.
Unlike the present six-speed transmission offered with the 4.6-liter ‘Tau’ V-8, the eight-speed transmission is not a ZF design, but one designed and fabricated entirely by Hyundai. Though not yet announced, we’re betting the V-6 Genesis model will stay with the six-speed automatic, which comes from Aisin.
The eight-speed matches the number of speeds offered on the Lexus LS, beats that of most Mercedes-Benz models by one, and will match that of the BMW 5- and 7-series, when those ranges begin using ZF’s eight-speed transmission.
