The fuel tank feeds a monstrous twin-turbocharged 6.0-liter V-12 set at a properly balanced 60-degree angle. In Pagani trim, the hand-built M158-series Mercedes-AMG mill outputs 737 pound-feet of torque and is tuned for immediate throttle response and minimal turbo lag.
As you can imagine, the engine sports some pretty impressive specifications. There is a dry-sump lubrication system to regulate oil flow; an oil/water heat exchanger that warms pertinent fluids; and a two-stage fuel supply system that uses one pump during normal driving, while the other actuates another during high stress runs. Hoses have been minimized to cut weight and clutter. The intercooler covers act as expansion tanks for the coolant system. (The little fins on top of the covers help to dissipate heat). The hand-welded rumbling titanium/Iconel exhaust weighs only 22 pounds. Even more impressive, the 2970-pound Huayra meets EU5 and LEV2 emissions. Xtrac's transverse mounted seven-speed sequential gearbox with dual-plate clutch (which weighs in at 221 pounds) handles the AMG might. If you're wondering why there is no dual-clutch setup, Pagani says he considered one, but ditched the idea once he noticed the barely improved shift times would not be worth the added 154 pounds.
Craftspeople lined the interior with classic Pagani bits like leather latches, aviation-inspired toggle switches, and a mechanical aluminum gearshift. The aluminum dash is milled from one solid block of metal and has a multi-function display that offers performance data in Sport Mode and a trip computer in Comfort Mode. Navigation and audio system, Bluetooth connectivity, and other luxury amenities come standard as well. Customers can choose specific hides and bespoke bits, too.
Horacio Pagani remains mum concerning the Huayra's performance capabilities and starting price, but you don't have to have a doctorate to know that both will blow you off your feet like a breath of Andean air.
