The Lamborghini Sián FKP 37 is a hyper-exclusive "few-off" model in a limited run of 63 coupes and 19 roadsters, taking its name from the Bolognese word for "flash of lightning". Its extreme carbon-fiber bodywork borrows futuristic design cues from the Terzo Millennio concept, including sharp Y-shaped running lights and active rear vents. The combination of an ultra-limited production run and jet-fighter styling gives it true collector status among modern hypercars.

The mid-mounted 6.5-liter V12 works alongside a 34-hp electric motor built directly into the 7-speed gearbox. Instead of a heavy lithium-ion battery pack, the hybrid system uses a supercapacitor mounted between the cockpit and engine bay. The entire electric setup weighs roughly 75 pounds, providing three times the energy density of a standard battery while fully recharging under braking to eliminate torque dip during high-speed gear shifts.
