In the era of electrifying sports cars, an unexpected duo breathes new life into a 90s icon. Singer, with its artisanal know-how, and Red Bull Advanced Technologies, the performance expert, join forces to make the Porsche 911 964 stiffer while preserving its soul. Get ready to experience a whole new level of driving!
A Bold Collaboration
The classic Porsche 911, an emblematic model, can now boast handling similar to that of a modern coupe. This transformation is the result of a bold collaboration between Singer and Red Bull Advanced Technologies, who have combined their strengths to increase the torsional rigidity of the restored Cabriolet and Targa versions by 175%. A technical feat that does not go unnoticed in the automotive world.
Red Bull Advanced Technologies, the high-performance engineering division of the Red Bull Technology Group, is globally recognized for its expertise in developing technical solutions in motorsport. On their side, Singer, founded in California in 2009, has made a name for itself in the custom restoration of air-cooled Porsche 911s, combining respect for the original model with the integration of modern technologies. The growing demand from clients eager to enhance the dynamic behavior of the open-top versions of the 964 has driven this innovative project.
Work on the Shell and Structural Simulations
The restoration process begins with a complete disassembly of the sports car. Every element is carefully removed — interior, body, and mechanical components — until only the steel shell remains. This is then inspected and prepared for the next steps, where Singer calls on Red Bull Advanced Technologies to apply simulation and structural analysis tools from the competitive world.
The chassis of the Porsche 964 is digitally reconstructed through scans and manual measurements. Finite element analysis software is used to simulate the behavior of the structure under stress, allowing for the evaluation of rigidity differences between the roofed versions and the open-top ones. This virtual model is refined until consistent results are achieved with physical tests conducted on real cars.

Carbon Fiber Reinforcements and More Precise Driving
Once the most torsionally stressed areas are identified, the teams design thirteen carbon fiber reinforcements. These structures are specifically designed to stiffen critical points without altering the original chassis or adding significant weight. The reinforcements are integrated into the digital model, adjusted to achieve the desired rigidity level, and then validated on a prototype.
During the restoration, these carbon fiber reinforcements are bonded directly to the shell. The result is astonishing: a 175% increase in torsional rigidity, a figure that truly transforms the driving experience. This gain in strength translates to increased precision in corners, better braking response, and an overall feeling of control, bringing the sensations of the Cabriolet and Targa versions closer to those of the traditionally stiffer coupe.
A Blend of Tradition and Modernity
Singer Classic Turbo services allow owners to restore their Porsche 911 inspired by the original 911 Turbo from 1974, offering a choice between coupe, convertible, or Targa bodies. This approach combines the charm of historic sports cars with modern technical solutions designed to enhance safety and road behavior without distorting the original car.
Ultimately, this collaboration between Singer and Red Bull not only improves the rigidity of an iconic car. It also demonstrates that it is possible to merge tradition and innovation to create a driving experience that transcends time. Thus, 911 enthusiasts can enjoy a model that respects its heritage while benefiting from contemporary technological advancements. A true renaissance for a legend!
