The Pagani Huayra BC Up Close

The engine is developed for Pagani by Mercedes who is a technical partner. It is a 6-liter twin-turbo V12 putting out about 800 hp at 5900 rpm and 775 lb/ft of torque at 5600 rpm.  The power is fed through a transverse 7-speed Xtrac single-clutch transaxle that is computer-controlled with a computer-controlled electro-mechanical diff for torque vectoring.  It doesn’t use dual-clutch technology like most supercars because the single-clutch trans with sophisticated electronic controls is about 40 percent lighter than dual-clutch transmissions like the Porsche PDK.

Here is the stock mufflerless titanium exhaust system.  It is all pie cut and burnt JDM style. That’s about the only thing people like us have in common with this car!  Half of the exhaust vents out the back while the other half blows the rear diffuser.  Notice the rear body clamshell has these cool titanium coilovers with a billet parallelogram linkage to hold it up?

This is the cooling duct/shroud for the scoop-fed engine oil heat exchanger.  Every trim part for the motor is dry carbon and this one is functional and a work of art.

This has got to be the nicest vin tag ever.  The Huayra has a full carbon tub instead of a unibody, just like a Prototype or open-wheel racer.  This assures a super lightweight and stiff chassis even though the car is a roadster with a removable roof section.  The car only weighs 2756 lbs!  That is feathery light.  For instance, our Project GT3RS, a simpler car, weighs about 3080 lbs even with mostly carbon and magnesium body panels.

You can see the outlines of the carbon tub here.  The tub is 100% autoclaved carbon with titanium inserts for bolting on the subframes and other structural parts.  The fact that this streetcar has a carbon tub is pretty impressive.
