FEATURE ARTICLE
Its single-speed G400 electric drive system is designed for both
primary drive for mid-size pure electric cars and secondary drive
for large hybrid vehicles. The scalable unit generates up to 4,000
Nm of additional torque and power, enough for pure electric mode
and a highly dynamic eAWD mode making it simpler to electrify
the rear axle in front-wheel drive platforms.
The single-speed G550 electric drive system is designed for larger
vehicles. The compact modular design generates up to 5,300Nm
of torque, enough for a dynamic pure electric mode for large battery EVs.

G400 from GKN
Inside its wide-range of edrive systems for different applications,
GKN uses a combination of electric motors, some sourced from
an external supplier and some using active motor parts which are
designed and manufactured in-house.

The topology for integrated e-drivetrains is a clear mandate,
believes GKN, as explained in a strategy paper, " Making Electric
Propulsion More Competitive " . The high efficiency of " P4 " electric axle drive architectures will make them central to most pure
electric and plug-in hybrid strategies. To provide the best balance
of cost and performance, single-speed systems are expected to
account for 94% of P4 eDrive volumes.
P4 electric drive architectures connect the motor directly to the
vehicle's axle, making it more efficient and cost-effective than
" P2 " and " P3 " systems that hybridize the main transmission. P4
systems send torque directly to the wheels and recover energy
directly from the wheel when braking. P4 electric drive systems
integrate the inverter and electric motor into a compact transmission module that applies torque to the axle.
