FLAGSHIP
The 2024 Celestiq's slender, lowroofline
exterior form drove structural
and process innovations underneath.
2024 Cadillac Celestiq spearheads GM's path to next-gen architectures,
processes and propulsion.

estoring the Cadillac brand to its golden-age pinnacle, when
it stood equal among Europe's ultra-luxury greats, has long
been an intermittent dream within GM. The grandiose
'Sixteen' concept in 2003 earned praise, raised hopes, and
narrowly missed production approval. Next year, however, another
no-compromises Cadillac - electric, of course - returns to take on
Rolls-Royce and Maybach in the battle of unbridled luxury. Each
Ultium-powered 2024 Celestiq will be bespoke - hand-built in a
dedicated $81-million facility located within GM's Warren, Mich.,
Technical Center and personalized to its " client's " request.
With an MSRP expected to begin at more than $300,000, Celestiq
can be a prestigious profit-earner for GM. Strategically, the dramaticproportioned
EV spearheads technologies that are expected to cascade
across GM's product portfolio. They include an architecture
dominated by large aluminum castings; mass adoption of
additive/3D printed components; sophisticated next-generation propulsion,
advanced chassis control and interior systems, and GM's
UltraCruise automated-driving tech.
" What you see in this program [Celestiq] is impacting our technical
direction in many others, " a GM executive engineer who requested
anonymity shared with SAE Media. To date, the intellectual property
around Celestiq includes approximately 300 approved and pending
patented technologies and processes.

New customer, new processes
Experienced leadership is particularly vital for success
in a clean-sheet vehicle program. GM kicked off
Celestiq nearly four years ago with veterans Tony
Roma as chief engineer, and Jeremy Loveday as program
engineering manager. Roma cut his teeth in
powertrain development and has many recent
Cadillacs, plus the Chevy Camaro ZL-1, under his
chief's belt. Loveday's first assignment at GM involved
the pioneering EV1 electric vehicle's aluminum structure.
He later dove deep into physical integration and
later served on Cadillac XT4.
Both engineers have gained an understanding of the
Celestiq customer and how that individual differs from
buyers of the XT6 or even the 2023 Lyriq, Cadillac's
first EV. " These truly are people that tell you about a
$100-million-dollar yacht that they spent three years
building, " Roma said. " They don't see roadblocks. They
don't understand the word 'no' like most of us do. And
'I can't afford that' doesn't enter their vocabulary. So,
we've baked a mantra - " Never tell a customer 'no' "
- into how we make the car and the material choices.
