Vehicle Description
Chassis No. ZHWUJ7ZD6MLA10477
First unveiled, appropriately online, in September 2019, the
company's new and highly advanced Si�n model took its name from
local Bolognese dialect, in which it translates as "flash" or
"lightning". Significantly, the car represented the first
production Lamborghini to incorporate any form of electrified
motive power-a shift of seismic technical magnitude further
reflected in the company's use of a non-bovine name for the first
time in many years. Such technical complexity determined the Si�n
as no ordinary Lamborghini, if indeed such a thing exists, and this
was reflected in its minimal production run. Just 82 Si�ns would be
constructed, with the 19 Roadsters and 63 coupes scheduled symbolic
of the year in which Ferrucio Lamborghini founded his eponymous
company.
Designed by former Porsche General Manager of Advanced Design Mitja
Borkert, the Si�n drew heavily on both the philosophy and mechanics
of its track focused Aventador SVJ sibling. Having previously drawn
widespread praise for its class-leading torsional rigidity, the
Aventador's carbon fiber monocoque chassis was retained, into which
a revised version of Lamborghini's legendary 6.5-litre V12 engine
was inserted. First seen in 2011, the Type-L539 unit benefitted
from continual development throughout the Aventador's lifecycle,
and the fitment of new titanium intake valves, a new exhaust
system, and a re-mapped ECU further boosted power from the 759
horsepower of the Aventador SVJ to some 774 for the unit fitted to
the Si�n.
Nevertheless, it was in the addition and operation of its hybrid
element that the Si�n's technical fascination lay. Ingeniously, the
car incorporated a small electric motor into its seven-speed
single-clutch transmission, the power for which was taken from an
onboard supercapacitor rather than a conventional hybrid battery
pack. However, while a supercapacitor's ability to store energy is
more limited than that of a battery, it can both re-charge and
deploy at a far greater rate. In the case of the Si�n, this enabled
the supercapacitor to be fully recharged with every brake
application.
Although only relatively modest in its output, the electric motor
operated simultaneously with the conventional V12 engine to
"torque-fill" between gearchanges, and provided an additional power
boost upon acceleration at speeds up to 80 mph. In addition to
augmenting the car's total power output to some 808 horsepower,
making the Si�n the most powerful production Lamborghini yet seen,
the entire system was further distinguishable for its relative
simplicity and functional weight of just 75 pounds.
Unsurprisingly, such technical competence was far from restricted
to the car's engine compartment. The Si�n's
electronically-controlled Haldex four-wheel drive system featured a
rear mechanical self-locking differential, while its four-wheel
steering system and push-rod operated twin wishbone suspension were
carried over directly from the esteemed Aventador SVJ. Braking was
still provided by massive six-piston front and four-piston rear
calipers, with each operating onto giant Carbon Ceramic discs,
albeit with the entire system appropriately modified to accept the
regenerative requirements of the Supercapacitor.
Externally, the Si�n pushed aerodynamic and stylistic boundaries in
typical Lamborghini fashion; the car's appearance is a
magnificently angular fusion of the traditional and the futuristic.
In terms of the former, references to the mighty Countach abounded,
not least in the trapezoidal front bodywork recess, side-mounted
air intakes and extravagant triple taillights. Yet in the case of
the latter, the utilization of intricate Y-beam headlights inspired
by the Terzo Millennio concept car, an electrochromic roof panel
and a finned rear deck-complete with active cooling flaps-all
showcased emerging technology tipped to feature on the next
generation of potentially rather more modestly priced
Lamborghinis.
Predictably, such prodigious power-and a highly accomplished
four-wheel drive system-afforded the car spectacular performance,
with 60 mph arriving in just 2.8 seconds and a top speed of 217
mph. Supplemented by a finely-tuned Electronic Stability Control
system and switchable driving modes of Strada, Sport, and Corsa,
the car offered three distinct characters yet demonstrated
excellent drivability and superb roadholding in each, not to
mention an incomparable accompanying soundtrack. However, it was
the car's admirable ability to "torque fill" which drew particular
praise from journalists; the somewhat disjointed operation of the
single-clutch gearbox on the Aventador SVJ being a recurring
criticism since rectified by the Si�n.
As one of only 63 Si�n coupes ever produced, this stunning example
was configured in conjunction with Lamborghini's in-house Ad
Personam studio at the fabled Sant'Agata factory. Boasting the
desirable exterior Carbon package, the car was finished externally
in Rosso Efesto, fading to Carbon, and was further complemented by
Nero Ade with Rosso Alala Alcantara trim, black brake calipers and
black wheels each with a red Diamond cut silhouette.
Unsurprisingly, such modifications did not come inexpensively; the
total additional cost amounting to some $236,720. Subsequently
imported into the United States by Automobili Lamborghini America
LLC of Herndon, Virginia it was distributed to Lamborghini St.
Louis, prior to its onward delivery to the consignor in 2022. In
his ownership it has been used only minimally-its odometer reading
a scant 244 miles at the time of cataloging-although it appeared as
a feature display at the Petersen Automotive Museum last year as
part of their "Hypercars: The Allure of the Extreme"
exhibition.
Few if any cars possess such monumental presence as the Si�n, and
fewer still justify such bravado with commensurate levels of
technical ability, performance or levels of finish. Further
enhanced by its status as the most complex, most powerful and,
arguably, the most technically significant production Lamborghini
yet constructed, it would appear that its future collector appeal
is all but assured. As such, the availability of a near-unmarked,
delivery mileage, single owner example such as this represents a
highly significant opportunity indeed, and one which should be
given due consideration by any committed Supercar or Hypercar
devotee.
