8HP: Formula for success
The challenge is to leave something out and end up with more. At first glance, this value-added formula appears to be a contradiction. But a closer look shows that the facts speak for themselves. Overview of the 8-speed automatic transmission product benefits.
8HP product benefits
| New gear set concept | Only 5 shift elements with 4 gear sets, of which only 2 are open in each gear. 3 multi-disc clutches and 2 brakes, enabling a compact, highly efficient design. |
|---|---|
| Higher overall gear ratio | Overall gear ratio of 7.0. The transmission consistently adapts to the optimum engine operating range for improved acceleration and lower fuel consumption. |
| Higher power-to-weight ratio | Lightweight components combined with a revolutionary gear set concept: 2 additional gears transfer more torque with fewer components and unchanged weight characteristics. |
| Lower drag loss and greater efficiency |
Only 5 shift elements with 4 gear sets, of which only 2 are open in each gear, and a new axially parallel vane cell pump increase the efficiency of the transmission. Energy losses are reduced to a minimum. |
