has identified
the ideal solution
and excellent potential for direct
energy recuperation, with no
engine or transmission power
losses. A coaxial eAxle is the ideal
solution in terms of packaging,
wrapping around the rear axle of
the vehicle, delivering direct drive
to the rear wheels and minimizing
parasitic driveline power losses.

G250C electric drive system is the

applications. Designed to fit into
the same space as a mechanical
rear di erential, the eAxle supports
a conventional internal combustion
engine, providing additional power
where needed. The lightweight
eAxle can help to lower overall CO
emissions, as well as allowing the
car to run for short journeys on
electric power only, with disconnect
functionality at higher speeds
further increasing e iciency.

Another option for OEMs is
to integrate a dedicated hybrid
transmission, like GKN Automotive’s
multi-mode eTransmission, used
in the Mitsubishi Outlander PHEV.
This o ers a compact, lightweight
transmission that combines power
from an internal combustion engine
and an eMotor, with the ability to
switch easily between full electric,
and parallel or series hybrid modes,
depending on the driving situation.
While most manufacturers are
developing long-term solutions
to meet emissions regulations,
they still need to consider how
e iciencies can be gained in
their current product ranges. Pure
electric vehicles have a key role
to play in overcoming the challenge
of reducing carbon emissions, but
the technology is still in its infancy
and remains an expensive solution.
In the short term, OEMs can
achieve significant CO reductions
by increasing the e iciency of their
current vehicles by hybridization of
the existing platforms. This
approach helps reduce the load
on combustion engines and
gradually reduces their reliance
on fossil fuels.
