This spot nearly went to the $5 million Bugatti W16 Mistral, but another rare Pagani just beat it out. The Pagani in question is the Huayra-based Imola.
Limited to a production run of only five units, the track-focused supercar was developed on the Imola circuit in Italy and is only one step below the Huayra R for sheer outrageousness. It relies on a 6.0-liter twin-turbo AMG-sourced V12 developing 816 horsepower and 811 lb-ft of torque, sent to the rear axle via a seven-speed automated manual gearbox. Helping those ponies hit the tarmac effectively is a reconfigured suspension system to reduce brake dive from the massive six-piston Brembo brakes clamping down on 15.7-inch rotors, and at each corner, sticky Pirelli Trofeo R tires.
It shed a bunch of weight, too, including 11 lbs from the method of painting, and weighs 2,747 lbs dry.
At $5.4 million, and all spoken for before the car was revealed to the world, the Imola is where we start this list of most expensive cars in the world.
