Enhanced Performance
and less Fuel Consumption

Fuel consumption and driving performance of the 9HP28 in comparison to competitors.

In addition to the design improvements mentioned at the beginning, the consumption-optimized driving strategy of the 9HP also contributes decisively to reducing fuel consumption. In total, the 9HP in the front-transverse sector realized consumption savings that were not thought possible: Compared to the 6-speed transmissions of the first generation, the 9HP saves up to 16 percent fuel.

The 9HP technology moves on eye level with the double clutch technology with respect to fuel consumption, and shows significant advantages with starting acceleration, which can be improved by >2 seconds in comparison to 6-speed automatic transmissions.

In order to be successful on the market, however, it is equally important to provide comfort and an attractive driving performance for the end customer. What is also worth mentioning here, is the speed reduction in the highest gear: It serves significantly better acoustics in the vehicle and increases driving comfort. ZF has designed all control components for shorter response and shift times in order to increase the performance. Direct multiple gearshifts further increase driving dynamics. In this process, shift points and shift dynamics can vary from an emphasis on comfort to very sporty which makes it possible to affect the performance of the vehicle according to the driver's wishes. Thus, the 9HP meets all requirements in terms of function and flexibility of modern automatic transmissions and shows the potential they also bear for front-transverse vehicles regarding their sportiness.
