Lamborghini stole the limelight from McLaren and Ferrari rivals on Monday by celebrating its 50th anniversary with an exclusive hypercar of which just three will be built.
Called Veneno, it costs 3 million euros ($3.9 million) plus local taxes. All three are sold.
Lamborghini CEO Stephan Winkelmann told journalists the car was "fastest, most powerful road Lamborghini we've ever built."
The mid-mounted V-12 engine makes 750hp and propels the two-seater to 100km/h (62 mph) in just 2.8 seconds. Top speed is 355 km/h (221 mph).
The Veneno is based on the Aventador but is lighter than the carbon fiber supercar by 125kg (275 pounds).
Its designer Filippo Perini told Automotive News Europe it was much more purposeful than Lamborghini's last exclusive hypercar, the Reventon. "That was more design driven, this car is much more driven by functionality," he said.
