Kia Motors has revealed details of its advanced new eight-speed automatic transmission (8AT), engineered for use in front-wheel drive vehicles. The new front-wheel drive 8AT (FWD 8AT) has been developed in-house by the Korean manufacturer, engineered to offer a high level of mechanical efficiency and smooth gearshifts. Crucially, the new FWD 8AT occupies the same space as a conventional six-speed automatic transmission, and weighs 3.5 kg less. Kia’s engineers already have experience of developing eight-speed transmissions for rear-wheel drive vehicles, mounting the transmission longitudinally and sending power to the rear axle. However, incorporating the same number of gears into a front-wheel drive car is incredibly challenging, due to packaging constraints and the need to mount the transmission transversely, competing with the engine, suspension and auxiliary components for space under the bonnet.
