Kia unveiled a new 8-Speed front-wheel-drive automatic transmission, that they developed. The transmission is about the same size as the 6-speed automatic transmission of the company, but it weighs 3.5 kilos less.
The development work began in 2012, while Kia has registered 143 patents for the new transmission, which promises improved performance, reduced noise, less vibration and lower NVH levels.
The transmission is mounted transversely and does not occupy much space. Therefore, the size of the oil pump is reduced in comparison with the pump of the automatic six-speed transmission. Kia indicates that it is the smallest oil pump that has been developed for a transmission of this particular category. It also has only 12 valves, thanks to the redesign of the body of the valve, allowing direct use of the electromagnetic clutch control valve, without additional control valves being required.
As a result of these changes, Kia says that the gear changes are now quicker, less fuel is consumed and there is less noise. The first model to wear the new 8-speed automatic transmission is the Cadenza, that is equipped with a 3,3-liter bi-turbo V6 engine, while it is expected to be available later in the remaining front-wheel drive models of the company.
