Huayra is the follow-up to the Zonda, the debut model from self-taught supercar auteur Horacio Pagani. It features an all-new chassis with a central monocoque made from titanium-infused carbon fiber, and the wheelbase has been stretched 2.75 inches over the Zonda. The suspension is pure race car stuff: double wishbones milled from billets of a copper-rich aluminum alloy called Avional, with pushrod-actuated Ohlins shocks.There was some wrangling over the new engine's configuration. Horacio Pagani didn't like the idea of turbos, and didn't like the naturally aspirated V-8 AMG first proposed as a replacement for the Zonda's 7.3. He wanted a V-12, but AMG engineers were insistent that to meet emissions and fuel consumption standards through the next decade, the engine had to have forced induction. AMG clearly knew what it was talking about. At cruising speeds, the Huayra is one of the most fuel-efficient supercars in the business, says Pagani, brandishing figures fresh from the test lab showing it has achieved 21 mpg (U.S.) on the Euro highway cycle.Nailing the gas in the Huayra is like lighting the afterburners on an F-15, though. The new V-12, codenamed M158 in AMG-speak, will pull cleanly and smoothly from as little as 1000 rpm, but once the tach needle swings past the 2500 mark and the turbos get into their comfort zone, the thrust is epic and utterly relentless all the way to 6000 rpm. I didn't go past 160 mph more than once on the bumpy, busy autostrada near Bologna, but the Huayra got there without breaking sweat; a casual canter en route to its claimed 230 mph top speed.
