Singer and Red Bull Advanced Technologies Reinforce Porsche 964 with 175% Torsional Rigidity Increase

Red Bull Advanced Technologies has partnered with Singer Vehicle Design to engineer a 175% increase in torsional rigidity for open-roof Porsche 964 Cabriolet and Targa models restored through Singer’s Classic Turbo services.

Singer’s process begins with the complete disassembly of a donor Porsche 911 (964). The steel monocoque is exposed, assessed, and prepared before structural engineering enhancements are integrated.

Red Bull Advanced Technologies digitally modeled the 964 chassis using scan data and manual measurements. Through Finite Element Analysis (FEA), torsional stiffness values were calculated and correlated with physical testing to ensure simulation accuracy.

Analysis revealed key load paths in open-roof variants. The solution: a formation of 13 bonded carbon fibre reinforcing structures strategically positioned to maximize stiffness while minimizing mass gain and preserving the integrity of the original monocoque.

The result:
✔ 175% increase in torsional rigidity
✔ Coupe-level dynamic behavior
✔ Enhanced handling, braking precision, and refinement

This collaboration represents the convergence of heritage restoration and modern motorsport-derived structural engineering.
