Broad Arrow "The Quail Auction 2026" Preview: 2020 Lamborghini Sian
A magnificently angular fusion of traditional and futuristic design, the Lamborghini Sián FKP 37 arrived as the marque's first foray into hybrid performance, signaling a genuine evolution for the brand. Only 63 examples were built; a figure Lamborghini has long reserved for its most exclusive limited runs, honoring the company's founding year of 1963. Having spent its life with a single caretaker, this example now emerges from that sole ownership to cross the block 13 - 14 August at Broad Arrow's Quail Auction. First unveiled in September 2019, the Sián FKP 37 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 name not associated with a legendary fighting bull for the first time in many years—instead taking its title from local Bolognese dialect, in which it translates as “flash” or “lightning”. Its subsequent “FKP 37” designation was a distinct homage to the initials of automotive engineering mastermind Ferdinand Karl Piëch, and his birth year 1937. Designed by Mitja Borkert, director of Lamborghini Centro Stile since 2016, the Sián was the production car maturation of Borkert's highly advanced Terzo Millennio concept car. The Sián 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, 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. For its mechanicals, the Sián turned heavily to 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-liter 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 Sián. Nevertheless, it was in the addition and operation of its hybrid element that the Sián'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 Sián, 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 Sián 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 Sián'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. 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. Such technical complexity determined the Sián as no ordinary Lamborghini, if indeed such a thing exists, and this was reflected in its minimal production run. Just 82 Siáns would be constructed, with the 19 Roadsters and 63 coupes scheduled symbolic of the year in which Ferruccio Lamborghini founded his eponymous company. Extensively tailorable through Lamborghini's bespoke Ad Personam division, no two examples are alike, and this 2020 Lamborghini Sián FKP 37 is thus presented in a truly unique livery. Making tasteful use of Lamborghini's signature paint fading effect, its front-facing Bianco Asopo finish gradually transitions to a fine Grigio Liqueo ombré. Verde Lampros accents highlight the Sián's many distinct angles as well as its desirable Carbon Package 1 (which cost $105,000). These electric green highlights delicately permeate its cockpit, peeking through the Nero Cosmus Poltrona Frau leather upholstery and sea of Alcantara. In total, this example has been specified with more than $260,000 worth of options according to its original window sticker. This singularly specified Sián was delivered new in March 2021 to its sole private owner in Los Angeles according to its clean CARFAX Vehicle History Report. In April 2026, Lamborghini of Newport in Irvine, California performed a comprehensive and preemptive 6th year service on the Sián, with invoices on file totaling nearly $16,000. The car has remained local since new and is offered now with just 284 miles at cataloging. Lamborghini's first hybrid model ticked all the boxes required of a cutting-edge Raging Bull; avant-garde, rowdy, and unapologetically ostentatious. This 2020 Lamborghini Sián FKP 37 is a recognizable representative of those tenets from Sant'Agata, boasting a striking specification and collector mileage that make it a worthy addition to any curated stable of remarkable Lamborghini models or other top-shelf hypercars. Should its next custodian choose to release this Bull from its pen, however, the reward is a visceral and exhilarating V12 driving experience perfected by the prime benefits of hybrid technology.
