For reference, that's enough to buy a new 911 Carrera. So what do you get for all that extra cash? Well, you get less. And that's the whole idea. The Weissach edition strips some 77 lbs off the Spyder's curb weight, thanks to widespread use of titanium, carbon fiber, magnesium and ceramics. The wheels, for example, shed 30 pounds of unsprung mass, and a race-livery foil wrap that replaces the paint. The result is a reported two-second drop off the car's
Nurburgring lap time. And that's nothing to sneeze at, particularly in a car that's schlepping around two powertrains. Whether the 918 Wiessach is worth $929,000 - or an extra Carrera over list - is another question entirely.
