Computational Generative Design & Unsprung Mass Reduction

Rather than machining traditional aluminum blocks, Czinger's software generates biomimetic lattice structures printed in high-strength titanium powder. This process eliminates unnecessary material along non-stress axes, shaving 40% of unsprung weight from each wheel assembly.

Paired with a hybrid powertrain producing 1,250 horsepower, the 21C Spyder represents a glimpse into the future of high-performance automotive manufacturing.
