November 2014: Weissach package

Comparative testing was performed between Porsche 918 Spider standard forged aluminium wheels and the Weissach package containing forged magnesium wheels, which over 60% of buyers have opted for.  The vehicle having factory standard configuration accelerated from 0 to 100 km/h in 2.8 seconds, from 0 to 200 km/h in 7.7 seconds, from 0 to 300 km/h in 22 seconds.  The same vehicle with the Weissach package, consisting of forged magnesium wheels, supplemented by the sports-version belts and several carbon fiber components, all together delivering weight savings of 35 kg in total, had demonstrated improved acceleration results amounting to 2.6, 7.2 and 19.9 seconds respectively.  The rotating mass of forged magnesium wheels represented the most significant contribution in the reduction.  Braking/stopping distance reduction was not measured as part of the study.
