Follow-ups to massive debuts are tough nuts to crack. But Argentine engineer Horatio Pagani did just that with the Huayra, the successor to his stop-the-presses Zonda. Back in the engine bay is a monstrous AMG-tuned power plant, this time a 6-liter twin-turbo V-12 producing 738 hp.

Wrapped around the driver and passenger of this roofless wonder is a tub made from a combination of carbon fiber and titanium for greater stiffness and lighter weight. But those are just the raw specs for a vehicle perhaps best known for being as meticulously refined as a Swiss watch, a true tastemaker’s triumph.  M.C.
