Development vehicle offers reduced fuel consumption, lower maintenance costs, fewer emissionsTROY, Mich., Jan 10, 2007 /PRNewswire via COMTEX News Network/ -- ArvinMeritor, Inc. and Wal-Mart
Transportation, Bentonville, Ark., have agreed to development of a dual-mode,
diesel-electric drivetrain for a Class 8 tractor. The vehicle, which is
believed to be the first dual-mode diesel-electric tractor prototype in
development in North America, will be based on an International Class 8
ProStar tractor and powered by an engine developed by Cummins Inc.
"We've been working on development of hybrid drivetrains for some time,"
said Carsten J. Reinhardt, president of the company's Commercial Vehicle
Systems (CVS) business. "This Class 8 project is a major step in our
continuing work in alternative drivetrain development - both for power
transmission and emissions - and holds tremendous promise for the worldwide
heavy-duty trucking market in a number of important environmental and economic
ArvinMeritor will provide the tandem axle, regenerative braking system,
air disc brakes and advanced ABS with integrated stability control and driver
assistance systems (from Meritor WABCO Vehicle Control Systems), software,
electronic controls, transfer case, motors, as well as the battery power from
a third party.
"ArvinMeritor is a leader in all areas of drivetrain and brake system
development for heavy-duty commercial vehicles and is an ideal partner for
Wal-Mart for the development of this dual-mode diesel-electric systems," said
Tim Yatsko, senior vice president-transportation for Wal-Mart. "We knew it
would take a highly integrated approach, and we believe ArvinMeritor
understands all of the pieces of the puzzle needed to complete this picture."
Wal-Mart had announced earlier that in the next 10 years, it intends to
double the fuel efficiency for its fleet of heavy-duty trucks.
Dual-mode diesel-electric drivetrains, which have both mechanical and
electrical propulsion systems, use the electric motor drive primarily for
periods of high demand under low-speed, high-load operating conditions, such
as accelerating from a stop. Once moving, the mechanical propulsion system
begins to blend its power with the electric motor until it reaches highway
speeds, where the drive phases to completely mechanical. The electrical
system can provide additional power during hill climbing, even at highway
In addition to its work at highway speeds, the engine also charges an
onboard energy storage system, which provides power to the electric motor when
demand is high. Energy that is generated during braking is captured and
stored using regenerative braking.
In March 2005, ArvinMeritor announced an arrangement with Unicell on a
commercial pick-up and delivery program with an ArvinMeritor alternative
drivetrain, featuring the company's electric axle and system integration of
motors, gears and controls. It offers zero emissions and fossil fuel
consumption, a ten percent increase in driver productivity from vehicle
enhancements. The end-user customer is considering a larger order of the
