How is it that the Porsche 918 Spyder Weissach Package is somehow even faster than the previously released specs? It already seemed impossibly fast, and impossibly efficient, but it appears that Porsche was being conservative with the earlier releases. The new specs are as follows:

0-60 mph: 2.5 seconds (0.2 seconds faster)
0-124 mph: 7.2 seconds (0.5 seconds faster)
0-186 mpg: 19.9 seconds (2 seconds faster)
Electric only 0-60: 6.1 seconds 
Fuel Economy: 75 mpg

How does that even make sense?
