Lamborghini Countach LP5000 QV (Quattrovalvole)
The Countach LP5000 QV Quattrovalvole was the definitive version of what is arguably the most visually dramatic supercar ever produced. The name 'Quattrovalvole' — Italian for four valves — described the critical upgrade that transformed the Countach from a spectacular-looking but somewhat sluggish machine into a genuinely fast supercar.
The four-valve cylinder head redesign was led by engineer Giulio Alfieri, who had previously worked at Maserati. Each cylinder now breathed through two intake and two exhaust valves, dramatically improving volumetric efficiency. Combined with the larger 5,167cc displacement, six downdraft Weber carburetors, and a revised exhaust manifold, the V12 produced 455 horsepower at 7,000 rpm and 500 Nm of torque at 5,200 rpm.
The QV was the widest Countach yet. Massively flared wheel arches accommodated 345/35 rear tires on 15-inch rims — the widest rubber fitted to any production car at the time. The car measured 2,000mm across the rear, requiring its driver to navigate with caution through normal traffic. The iconic side intakes, NACA ducts, and louvered engine cover created a visual spectacle from every angle.
The chassis retained the original Countach's tubular steel space frame, with independent double-wishbone suspension at all four corners. The unassisted steering was heavy at parking speeds but communicated well at higher velocities. Brakes were unassisted ventilated discs — stopping the 1,490 kg car from high speed required significant pedal pressure and forward planning.
The interior was surprisingly intimate. Two occupants sat in deeply bolstered seats with the transmission tunnel rising between them. The instrument cluster was basic but functional, with a large tachometer and speedometer flanked by minor gauges. Air conditioning was available but struggled against the heat generated by the mid-mounted V12.
The LP5000 QV was produced from 1985 to 1988, with approximately 610 units completed. It remains the most collectible standard Countach variant, offering the purest expression of Marcello Gandini's radical wedge design combined with the most potent carbureted V12 engine. For many enthusiasts and collectors, the QV represents the ultimate analog supercar experience.
Tubular space frame integrity is the most important structural check — corrosion can be hidden beneath body panels. Six Weber carburetors must be properly synchronized and jetted. Clutch and gearbox condition are critical — repairs are expensive. Verify scissor door mechanisms work smoothly. Check for evidence of repaint — many Countachs have been resprayed. Documentation and service records significantly affect value.
Manufactured at Lamborghini's factory in Sant'Agata Bolognese, Italy between 1985 and 1988. Total QV/Quattrovalvole production was approximately 610 units. Bodywork was produced by Bertone and assembled at the Lamborghini factory.
