Cadillac has unveiled the Lyriq fully
electric crossover, after its debut was postponed from its original April 2
date due to the declaration of a health emergency in March after 14 people
tested positive for the coronavirus in Los Angeles, where the debut was planned,
in March. The Cadillac Lyriq is based upon the firm’s third-generation modular
electric vehicle platform, which offers the EV crossover greater range and
better passenger space compared to an adaptation of an existing combustion
engine platform, the American carmaker says.
This platform houses modular drive systems
as well as the new Ultium family of drive batteries, and being an integral part
of the architecture that contributes to its safety as well as ride and
handling. The lower centre of gravity and a nearly-even 50:50 weight
distribution courtesy of the battery pack’s placement results in “a vehicle
that’s sporty, responsive and allows for spirited driving,” says Cadillac. Electricity
is stored in the Ultium battery system which offers 100 kWh in the Lyriq, and
which can be charged at rates of over 150 kW with DC charging. This offers more
than 480 km of driving range on a full charge, the automaker said.
Comprised of NCMA
(nickel-cobalt-manganese-aluminum) chemistry, the battery uses aluminium in the
cathode to reduce the amount the amount of rare earths used, and General Motors
engineers have reduced cobalt content by 70% compared to GM’s current
batteries. The battery chemistry is packaged in large, flat pouch cells that
reduces complexity and simplifies battery cooling needs, says the automaker.
The battery’s electronics are incorporated directly into the modules, allowing
the removal of nearly 90% of battery pack wiring compared to those in the
company’s current EVs, said GM.
The Lyriq employs a primarily
rear-wheel-drive layout, with optionally available all-wheel-drive in a higher
performance version. The AWD version features an additional drive motor on the
front axle, allowing for “a significant amount of tuning flexibility, enhancing
vehicle dynamics and performance for drivers,” says Cadillac. The automaker has
yet to release official performance details for the Lyriq.
A ‘choreographed lighting sequence’ in the
Lyriq welcomes its occupants upon entering, at the same time preparing the
cabin for the journey by making adjustments to the seats, mirrors and climate
control. Featured on the dashboard is a 33-inch LED display which offers drive
information, infotainment controls as well as camera views, and the display has
the highest pixel density of any screen in the automotive industry today, as
well as the ability to display over one billion colours, says Cadillac. The
screen will enable the driver to monitor the vehicle’s battery charging status,
as well as forecasting its energy consumption and can provide charging
suggestions. A new, dual-plane augmented reality-enhanced head-up display that
offers information on two planes; a near plane displaying speed and direction
of travel, and a far plane displaying transparent navigation signals and other
alerts.
The Lyriq packs a number of assisted
driving features. The crossover features the latest version of Super Cruise
hands-free driver assistance feature, here including lane change on demand.
Also featured is supervised remote parking, where ultrasonic sensors are
employed to help the Lyriq park itself in parallel or perpendicular parking
spaces, either with the driver in the vehicle, or outside.
A new road noise cancellation will feature
for the first time in a Cadillac with the Lyriq, featuring accelerometers in
addition to microphones in order to target the frequency range of tyre cavity
noise that needs to be reduced for a quieter cabin, says Cadillac. This will
come as part of a 19-speaker AKG Studio sound system that will be offered when
the Lyriq goes to market.
As at March when the Lyriq was shown in
concept form at GM’s EV Day, the electric crossover is reportedly 85% true to
the production vehicle, where the concept featured 23-inch wheels and powered
doors. Cadillac refers to this latest iteration of the Lyriq as a show car,
which suggests it is rather closer to production readiness than a concept. The
crossover remains some way off, however, as it told The Verge that it won’t
enter production until ‘late 2022’, likely starting production in China before
it does in the United States.
