Allison Transmission Announces Global Launch of 9-Speed Transmission and Expanded Electrification Portfolio At IAA

Company also continues work to support customers with connected
capabilities for a single, efficient fleet management experience

HANNOVER, Germany–(BUSINESS WIRE)–Allison Transmission today announced that it will offer its medium-duty,
fully automatic 9-speed transmission globally, and that it has developed
an electric hybrid system with purely electric extended range. The news
was revealed at the 67th IAA Commercial Vehicles show.

“Right now is an exciting time to be part of Allison and our industry as
a whole,” said David S. Graziosi, president and CEO of Allison
Transmission. “There is more rapid change in our industry and more
Allison initiatives underway today than at any point during the last

With its deep first gear ratio and industry-leading ratio coverage, the
Allison 9-speed transmission provides significant fuel savings as the
highly efficient gear train allows the torque converter to lock up early
in first gear. Additionally, the 9-speed includes an optional integral
engine stop-start system that provides immediate transmission engagement
and vehicle hold while the engine is restarted. Providing value for a
variety of applications, the 9-speed transmission is ideal for
distribution trucks, rental and lease trucks, and school buses.

“With this new transmission, Allison continues to demonstrate its
commitment to help achieve standards regarding fuel efficiency and
vehicle emissions,” said Graziosi.

The Allison 9-speed model leverages the proven durability of the Allison
2000 Series™ 6-speed transmissions, which have accumulated more than 100
billion miles globally. It has been designed to utilize the same vehicle
manufacturer’s interfaces as its 6-speed predecessor, providing ease of
integration into vehicles currently released with the Allison 2000

In addition to the 9-speed transmission, Allison also announced the
expansion of its electrification portfolio with an electric hybrid
system that includes a purely electric extended range—up to 15
kilometers. Ideal for transit bus and motor coach applications, the
system features zero-emissions with engine off, including approaching,
during and leaving passenger stops for a quieter and healthier

Additional features include a higher energy Li-ion battery for extended
engine off range; a smaller, lighter dual inverter with water ethylene
glycol cooling for more efficient operation; and Increased Power
Accessory II to improve fuel economy by using the hybrid system to power
accessory components like air conditioning, air compressors and power

“This hybrid with extended electric range builds on one of the most
dependable and efficient hybrid-propulsion systems,” said Graziosi.
“With over 8,000 buses around the world using our system since 2003,
Allison was a pioneer in electrification and remains a trusted brand.”

The system is pure electric capable, but no electric charging
infrastructure is required. Battery charging is accomplished via
regenerative braking and engine operation. The regenerative braking
capability can extend the brake change interval by up to 350 percent.
The two-mode split parallel architecture improves fuel economy up to 25

Beyond the 9-speed transmission and extended electrification portfolio,
Allison also continues to work with telematics service providers (TSPs)
and vehicle manufacturers to support existing and new customers with
connected capabilities for a single, efficient fleet management

Backwards compatible to fourth generation electronic controls, which
were first produced in 2005, the new connected capabilities will provide
insight into over 170 different transmission conditions. This will
provide fleet management and maintenance staff with the insight they
need to improve vehicle uptime.

Allison will begin delivering transmission health information via
multiple North American TSPs by year-end. Support for additional
applications and global regions is planned.
