ZF introduces 8-Speed Automatic Transmission
The more demanding the requirements for comfort and efficiency, the more important are advanced transmissions – in passenger cars just as in light commercial vehicles. For this reason, the Italian commercial vehicle manufacturer, Iveco, chose the efficient, dynamic, and comfortable 8-speed automatic transmission (8HP) by ZF to shift gears in the latest generation of its Daily, a light commercial vehicle model with caravan body.
The transporter will in future even enhance the characteristics owing to which it was awarded the title “International Van of the Year 2015″ at the end of September 2014.
The annual “International Van of the Year” award is conferred by a jury consisting of 23 leading journalists of the major international commercial vehicles trade magazines. Iveco Daily is the 2015 winner. The jury justified their decision by the high efficiency standards offered by the Iveco Daily and its contribution to sustainable goods transport.
This contribution may even increase in future as ZF’s 8-speed automatic transmission further enhances fuel efficiency and considerably adds to driving comfort at the same time. Thanks to its special characteristics like wide spread of gear ratios, outstanding efficiency, as well as shift times below the human threshold of perception, the ZF 8HP has become the benchmark among passenger car automatic transmissions.
Currently, it is used in more than 1 000 vehicle applications – from compact cars to full-size high-end luxury cars and pure sports cars. But Iveco and its new Daily with ZF’s 8HP prove that also completely different vehicle segments can benefit from these advantages. This is the first time an 8-speed automatic transmission is installed ex works in this model.
The eight gear steps together with the high spread of gear ratios guarantee that the engine speed and therefore also the fuel consumption stay at a low level. Not least, the 8HP always automatically chooses the right gear ratio to also tackle steep and twisty uphill routes with the vehicle without any problems.
Apart from the advantages on the road, there were some more important reasons for Iveco to opt for the advanced automatic transmission by ZF in the new Daily: It can be combined flexibly with all engines for this model – with the diesel and natural gas engines just as with each of the nine different power stages from 106 to 205 hp. The 8HP70 used in the Iveco can cope with very high input torques and is thus suitable in particular for the Daily and its permissible total weight of 7 tons.
But also drivers who still want to shift gears manually in the new light commercial vehicle by Iveco get sophisticated ZF driveline technology: As a standard, the Daily is produced with the manual 6-speed Ecolite transmission including the corresponding clutch system by the technology company. With regard to the chassis, the successful model is equipped with ZF dampers representing safety and comfort. The steering pump and the steering column, however, are delivered by ZF Lenksysteme GmbH, a 50:50 joint venture of Robert Bosch GmbH and ZF Friedrichshafen AG.
