A WORLDWIDE PREMIERE: STEYR AND FPT INDUSTRIAL TOGETHER FOR THE NEW HYBRID TRACTOR CONCEPT

Turin, November 10th, 2019

Innovation and sustainability are the key elements of the newest “STEYR Konzept” which fea-
tures FPT Industrial motors. At the Agritechnica trade fair in Hannover, Germany, FPT Indus-
trial and STEYR, CNH Industrial brands, are presenting a new, jointly-developed hybrid
tractor concept. This is the result of a project, which saw close collaboration between the two
brands’ respective Innovation and Engineering teams.

FPT Industrial took up the challenge to develop a wholly-new propulsion concept focused on
efficiency, performance, productivity and sustainability, which meets customer requirements
for a tractor guaranteeing high torque peaks during specific applications. With its involvement
in the development of this STEYR Konzept, FPT Industrial underlines its role as a full system
integrator, capable of managing, combining and controlling all the software and hardware ele-
ments of highly-complex powertrains.

The new concept features innovative architecture, with a serial hybrid approach whereby the
diesel engine, a compact 4.5-liter 4-cylinder unit, instead of the 6-cylinder traditionally in-
stalled on such a tractor range, works at optimal speed as an energy generator, charging bat-
teries. The engine is disconnected from the wheels, and traction is provided by four
independent electric motors directly installed in the wheel hubs.

The many benefits offered by this architecture include optimized efficiency and balanced
mass distribution thanks to electric motors affixed to the wheel hubs. The downsizing of the
combustion engine offers significant advantages in terms of fuel consumption and CO2
reduction. A “pure electric” drive mode is possible for zero-emission and low-noise op-
erations. This architecture also permits the integration of individual motors, incorporating a
separate suspension and steering system, which results in four fully independent wheels
electronically controlled, thereby improving safety, grip, handling and response.

Independent wheel hub motors allow superior traction control, enable energy recovery when
braking, and reduce brake and tire wear. Electric boost improves dynamic behavior and
gives the operator the instantaneous extra-torque needed in heavy tasks. The STEYR
Konzept is equipped with a NEF45 engine, which delivers 150 kW peak power, while 250 kW
peak power in hybrid boosting mode is guaranteed. The concept can reach 10% fuel saving
compared with pure Diesel on some specific tractor missions.

Traditional tractor operation is ensured by electrically driven hydraulic systems and a me-
chanical PTO; an additional motor can be added to drive electrical implements for higher
precision operation.

The battery pack is modular, which is a key feature to guarantee the appropriate pure–
electric autonomy range in all missions, this will also play a central role in future
electrification projects.

With the hybrid tractor concept, FPT Industrial has provided STEYR with innovative
powertrain solutions that are both flexible and customizable, and represent state of the art of
heavy-duty hybrids today. “This concept is a new and important milestone for FPT Industrial,
which continues its strategy of developing innovative and sustainable solutions for the mar-
ket. The hybrid concept also underlines the Brand’s position as full system integrator, ensur-
ing our clients benefit from the best solutions for each industrial mission and application. We,
in FPT Industrial, are always striving for more, exploring new frontiers of the powertrain indus-
try in the near future”, states Selin Tur, Head of E-Powertrain.
