Carelli Design C928 Porsche

The new C928 would wind-up
sporting a variety of extensive
modifications and upgrades. Among
the most obvious was an extensive
reconfiguration of the interior
appointments, a redesign of the vehicle’s
doors and the creation of a handsome
new trunk for luggage, as a result
of the vehicle’s new
convertible top.

automakers Rolls Royce
and Jaguar.

When in the down position, the
new convertible top is skillfully
stored entirely in its own concealed
storage compartment, a feature
relatively common by today’s standards
but nearly unprecedented in the
late 70’s and early 80’s.

Engineering a convertible top
was the first challenge. Designing
it to disappear into a totally concealed
chamber required extensive engineering
since none of this existed in the original
coupe, or any other Porsche for
that matter.

Those who knew something about
the 928’s new chassis, in particular
Porsche’s own hardcore engineers
were all quick to point out that any
attempt to modify the 928’s existing
chassis (a unibody structure based on
monoblock technology) would be a
near-impossible task.

With an annual production of over
15,000 units, and a workforce of some
4200, Porsche seemed gigantic when
compared to small automakers, particularly
those of Italian and English persuasion
which produce a mere 50 to 2,000 cars
annually. Big or small, Porsche appeared
to Carelli Design as a Giant, and for
Carelli International’s founder and CEO,
Vittorio G. Carelli, it was a perfect fit.

for the entire project, during which
Carelli Design’s MESA team assumed
responsibility for the entire research,
engineering, eventual vehicle design as
well as the production of eight completed
prototypes. Completion was on-time with a
final project development cost in excess
of 2.5 million dollars, followed by
an enormously successful round of
international debuts beginning in 1981
at the AutoExpo in Los Angeles
California.

The success of the C928 project

recognition to Carelli Design’s C928

from around the world acknowledged Carelli
Design as a new creative powerhouse
—having demonstrated its ability
to beautifully style highly complex
products in harmony with their
maternal makers.

The C928 project perhaps would
have never seen the light of day,
if it were not for the company’s
early business activities and integral

manufacturer itself. It may even be
said that it was Vittorio Carelli’s
early unrelenting fascination with
the Porsche automobile that
Carelli International exists today.

Carelli Design C928 Porsche
Developed by Team MESA—1980-1981
Carelli Design, A New Creative Powerhouse

In the spring of 1979, Porsche Audi of North America and Carelli International Corporation launched an aggressive effort to develop a special limited series 928 convertible. The model would eventually become known as the Carelli Design C928 Porsche Convertible.

The challenge

The new C928 would wind-up sporting a variety of extensive modifications and upgrades. Among the most obvious was an extensive reconfiguration of the interior appointments, a redesign of the vehicle’s doors and the creation of a handsome new trunk for luggage, as a result of the vehicle’s new convertible top. The C928’s new interior featured lush Connelly leather hides out of England, a luxury only previously engaged by the automakers Rolls Royce and Jaguar. When in the down position, the new convertible top is skillfully stored entirely in its own concealed storage compartment, a feature relatively common by today’s standards but nearly unprecedented in the late 70’s and early 80’s. Engineering a convertible top was the first challenge. Designing it to disappear into a totally concealed chamber required extensive engineering since none of this existed in the original coupe, or any other Porsche for that matter. Those who knew something about the 928’s new chassis, in particular Porsche’s own hardcore engineers were all quick to point out that any attempt to modify the 928’s existing chassis (a unibody structure based on monoblock technology) would be a near-impossible task.

The result

Completion was followed by an enormously successful round of international debuts beginning in 1981 at the AutoExpo in Los Angeles California. Nearly every auto publication from around the world acknowledged Carelli Design as a new creative powerhouse having demonstrated its ability to beautifully style highly complex products in harmony with their maternal makers.

Why the Carelli Design C928 Porsche?

The company, Dr. Ing. H.C.F. Porsche AG has often been described as the smallest among auto factories, and while that might be true within Germany, international comparisons prove otherwise. At the time of the C928 project, Porsche’s production was approximately 15,000 units annually, with a work force of some 4,200 employed. That could seem gigantic when compared to other small automakers, particularly those of Italian and English persuasion with annual productions of 50 to 2,000 units. Truth be told, Porsche’s 928 coupe received a lukewarm reception from their traditional steadfast customer base. The special limited series Carelli Design C928 Porsche convertible was a major attempt to boost, or rather draw attention to the 928 product. Carelli Design had already been in the creative spotlight, receiving positive press on custom one-of-a-kind vehicles. The price tag for owning a custom Carelli Design vehicle in 1979 would often cost their new proud owner as much as $350,000.

The story behind the Carelli Design C928 Porsche

The company, Dr. Ing. H.C.F. Porsche AG has often been described as the smallest among auto factories and while that might be true within Germany, international comparisons prove otherwise. At the time of the C928 project, Porsche’s production was approximately 15,000 units annually. That could seem gigantic when compared to small automakers, particularly those of Italian and English persuasion with annual productions of 50 to 2,000 units. Big or small, Porsche appeared to Carelli Design as a giant and for Carelli International’s founder and CEO, Vittorio G. Carelli, it was a perfect fit.

From a modest beginning to the creative spotlight

To the surprise of many, Carelli International began as a small independent service center of Porsche automobiles. The Carelli name quickly became a prominent enterprise with a reputation for technical excellence. Vittorio Carelli had acquired a profound understanding about every nut-and-bolt of the Porsche product. His technical aptitude, attention to detail, and steadfast scrutiny to deliver exacting perfection were already evident during his early childhood. In 1978, the Carelli enterprise set forth on independent design ventures, which soon provided for the creation of a full-scale transportation design facility located in Costa Mesa, California. The modern facility was dedicated entirely to vehicle transportation design and often referred to as Carelli Design. Our journey from the beginning

The C928 project would have perhaps never seen the light of day if it were not for the company’s early business activities and integral ties with the legendary automobile manufacturer itself. It may even be said that it was Vittorio Carelli’s early fascination with the Porsche automobile that is responsible for the modern existence of Carelli International today. Our company contributes much of its ideology and engineering principles to those early years influenced by Porsche. The eventual success of the C928 Porsche design brought acclamation and worldwide recognition to the company’s small team of inspired designers and engineers, at the time a mere 28 employees in all.
