THE SHIFT Every Supercar has a Story. Live it with Us.
ONCE FOR ONE
Some cars were never meant to be repeated.
They weren’t built to test ideas or preview futures.
They were commissioned, requested, insisted upon.
A one-off exists because one individual had a vision,
and a manufacturer or coachbuilder agreed to build it.
Supercars built once, for one person.
Not to scale. Not to trend. Not to be understood by the market.
No replicas. No series intent. No second attempts.
One-Offs are finished statements.
This is the first article in the ONE-OFFS series.
More commissioned machines will follow
in future editions of THE SHIFT.
FERRARI 375 MM
“INGRID BERGMAN” • 1954
Commissioned by Roberto Rossellini, for Ingrid Bergman.
This Ferrari wasn’t created for competition or prestige.
It was created as a personal gesture.
Rossellini asked Ferrari for something elegant, intimate, and different.
Scaglietti answered with curves that felt emotional rather than aggressive.
In doing so, Ferrari revealed a quieter side of its identity,
one where beauty mattered as much as speed.
Finished in Grigio Ingrid, the understated tone reinforced its elegance and set it apart from Ferrari’s traditional racing reds, perfectly matching the car’s more intimate purpose.
Specs & performance
V12 Colombo, 4.5L
≈330 hp
0–100 km/h ≈6.0 s
Top speed ≈280 km/h
FERRARI
TESTAROSSA SPIDER • 1986
Ferrari never intended the Testarossa to lose its roof.
Agnelli didn’t ask for permission, he asked for execution.
What’s remarkable isn’t that Ferrari said yes, it’s how quietly they did it.
No press release, no replicas, just one car altered for one man who didn’t need explanation.
Specs & performance:
Flat-12, 4.9L
390 hp
0–100 km/h: ~5.3 s
Top speed: ~290 km/h
FERRARI P4/5
BY PININFARINA • 2006
The P4/5 was commissioned as an act of memory.
Glickenhaus wasn’t chasing nostalgia, he was chasing correctness, a belief that Ferrari’s most beautiful era had something timeless to say.
Built on an Enzo chassis, shaped by Pininfarina, it feels almost defiant in its restraint.
A modern car that refuses to look modern.
Specs & performance
V12, 6.0L (Enzo-derived)
≈660 hp
0–100 km/h ≈3.5 s
Top speed ≈350 km/h
FERRARI SC40 • 2025
This is what happens when the spirit of the F40 is translated, not copied.
Commissioned by a private collector, the SC40 isn’t interested in being retro or polite.
It’s interested in being honest, about speed, about noise, about intent.
Ferrari doesn’t build cars like this often.
Usually, it takes a very specific client to unlock them.
Specs & performance
Twin-turbo V8
≈760 hp
0–100 km/h ≈2.9 s
Top speed ≈330 km/h
FERRARI SP12 EC • 2012
Eric Clapton’s Ferrari is about restraint.
Inspired by the 512 BB, but filtered through personal taste rather than ego, it avoids theatrics completely.
This is what happens when a collector values lineage more than spectacle.
It avoids drama entirely,
and that’s exactly why it works.
Specs & performance
V8, 4.5L
570 hp
0–100 km/h ≈3.4 s
Top speed ≈325 km/h
BUGATTI BROUILLARD • 2025
The Brouillard was commissioned by Michel Perridon,
founder of The Perridon Collection and a lifelong Bugatti devotee.
Named after one of Ettore Bugatti’s favorite horses, the car carries its heritage quietly but deliberately.
Finished in a striking shade of green, it stands alongside La Voiture Noire as one of the most dramatic and emotionally charged Bugattis ever produced.
Perridon, a computer mouse entrepreneur who quite literally clicked his way into automotive history, didn’t ask for spectacle. He asked for meaning.
Perhaps the most personal detail is inside:
a glass insert containing a miniature horse, embedded in the machined aluminum gear shifter, a subtle but powerful tribute to Ettore’s love of horses.
This isn’t excess for its own sake. It’s reverence, expressed through craftsmanship.
Specs & performance
W16 quad-turbo
1578 hp
0–100 km/h ≈2.4 s
Top speed electronically limited
ASTON MARTIN VICTOR • 2020
Commissioned by a private collector, the Victor exists because someone refused to accept compromise.
A massive V12, a 6-speed manual gearbox, and no apology for either.
It’s Aston Martin briefly stepping away from modern expectations.
Built once, without concern for trends,
it feels honest in a way few modern cars do.
Specs & performance
V12, 7.3L
836 hp
0–100 km/h ≈3.0 s
Top speed ≈320 km/h
FERRARI
P4/5 COMPETIZIONE • 2011
The road-going P4/5 wasn’t the end of the story.
James Glickenhaus wanted to know if the idea could survive racing.
The Competizione traded elegance for credibility.
Entered at the Nürburgring 24 Hours, it earned its relevance rather than being granted it.
In 2011, the original entry in the 24 Hours of Nürburgring finished 39th overall and second in class in the experimental category.
In 2012, after upgrades including KERS, the car returned and finished 12th overall and first in its class (E1-XP / experimental group) — a remarkable result for a one-off entry.
Specs & performance
V8, race-tuned
≈500 hp
0–100 km/h ≈3.0 s
Top speed ≈330 km/h
LAMBORGHINI
AVENTADOR J • 2012
The Aventador J was commissioned by a private collector, and it feels deliberately unreasonable.
No roof. No windshield. No concern for comfort.
It exists because Lamborghini occasionally needs to remind itself
that excess is part of its DNA.
Specs & performance
V12, 6.5L
700 hp
0–100 km/h ≈2.9 s
Top speed ≈300 km/h
FERRARI KC23 • 2023
Commissioned by a private collector, the KC23 shows Ferrari without a rulebook.
Based on a race car but freed from regulation, it explores what design becomes when permission is removed.
This is Ferrari thinking out loud.
Specs & performance
Twin-turbo V8
≈600 hp
0–100 km/h ≈3.0 s
Top speed n/a (track-only)
MASERATI PERALTA S • 2025
Commissioned by Carlos Peralta, designed by GFG Style.
The Peralta S is a conversation across generations.
Giugiaro’s influence is unmistakable, particularly the sharp, architectural language first explored in the Maserati Boomerang, but it is never copied, only reinterpreted through modern materials and restraint.
It proves that significance can come from proportion, restraint, and intention, not from visual aggression.
Specs & performance
Twin-turbo V6
630 hp
0–100 km/h ≈2.9 s
Top speed ≈325 km/h
MCLAREN X-1 • 2012
The X-1 is McLaren thinking like a sculptor rather than an engineer.
Instead of celebrating speed through angles and aggression, it explores motion through surface, curvature, and flow.
Panels slide, lines soften, and the body appears to move even when standing still, an approach almost unheard of in McLaren’s typically clinical design language.
Based on the 12C, but visually detached from it, the X-1 was never meant to define a future range or inspire production models.
It exists as a closed conversation among the client, a long-time McLaren client, and the studio, where repetition would have diluted the idea.
Built once, because some shapes only make sense when they remain singular.
Specs & performance
Twin-turbo V8, 3.8L
616 hp
0–100 km/h ≈3.1 s
Top speed ≈330 km/h
PORSCHE 935 “STRASSENVERSION” • 1983
Commissioned by Mansour Ojjeh, TAG Group founder, through Porsche’s Sonderwunsch programme, a 911 Turbo was transformed into a road-legal interpretation of the 935 for one of motorsport’s most influential patrons.
Not a homologation special and never a series, this was a bespoke road car wearing race-bred bodywork, widened arches, and competition-inspired hardware, engineered to bridge circuit intent with street use.
It existed because a client asked for something extraordinary, and Porsche agreed to build it once.
Specs & performance
Flat-six turbo, 3.3L
≈380 hp
0–100 km/h ≈5.0 s
Top speed ≈300 km/h
WHEN INTENT TAKES PRECEDENCE
What connects these cars isn’t performance figures or price tags.
It’s the moment when someone decided not to settle.
Not to choose what was available, or acceptable, or easy.
Each of these machines began as a conversation that could have ended with “no.”
Instead, it became a refusal to repeat what already existed.
WHY ONE-OFFS STILL MATTER
One-offs have always fascinated me, not because they’re louder or faster, but because of the mindset behind them.
They exist in a space where personal conviction outweighs market logic, where taste matters more than trends, and where permanence is valued over volume.
Building something once, knowing it will never be repeated, is a deliberate act.
In a world increasingly shaped by sameness, these cars quietly remind us that individuality still requires intention.
