CHASSIS & POWERTRAIN

& DRIVETRAIN

The frame to support the drivetrain and powertrain requires both high
rigidity and light weight. For this reason, frame structures using
high-strength structural aluminum alloy sheet and extruded shapes are
increasingly being used. More aluminum forged products are also being
used for the suspension, as well as parts such as brake calipers, hub
carriers, and steering knuckles.

JAGUAR I-Pace

The I-PACE is the SUV version of Jaguar’s first all-electric
vehicle, with a body consisting of 93% aluminum. This light
and strong architecture delivers exceptional torsional
stiffness. The I-PACE uses two electric motors, one on each

axle, for permanent four-wheel drive. Its power train provides
400PS of power with 696Nm instantaneous torque, powered
by a 90kWh lithium-ion battery. It was chosen by 60
automotive journalists from 23 European countries as the
winner of the 2019 European Car of the Year Award.
