If the 'base' model's top speed of 211 mph and 0-60 of just under three seconds simply wasn't enough for you, Porsche offers a Weissach Sport Package. That variant of the 918 shaves 77 pounds off the weight of the car while adding on a carbon-fiber roof, side mirrors, and your choice of two sport racing liveries-all for the low additional cost of just $84,000. Decals and illustrated instructions are included.
