Singer & Red Bull Boost Porsche 911 964 Cabriolet Rigidity by 175%

Singer and Red Bull Advanced Technologies have developed 13 carbon fiber structures to increase the torsional rigidity of Porsche 964 cabriolets and targas by 175%. This collaboration allows the open-roof versions to achieve the handling dynamics of coupes, while Singer simultaneously launches its new 911 Carrera Cabriolet Reimagined limited to 75 examples.

"Singer's challenge was to increase the rigidity of Type 964 open-top models, giving them the same dynamic performance as the coupe while minimizing added weight" — Rob Gray, Technical Director, Red Bull Advanced Technologies

The 964 convertibles have always suffered from a congenital flaw: lack of rigidity. Remove the roof from a car engineered as a coupe, and you introduce structural flex that hurts handling. Singer and Red Bull Advanced Technologies found the answer.

A Scientific Approach to Reinforcement

The process begins with complete disassembly of the Porsche 964. Body, interior, and mechanical components are stripped away until the bare steel shell is exposed. It's on this foundation that Red Bull Advanced Technologies applies its simulation tools straight out of Formula 1.

The chassis was reconstructed digitally using scan data and manual measurements. Using finite element analysis software, engineers assessed the rigidity differences between closed and open versions. The virtual model was then refined until results matched physical testing.

13 Carbon Structures for a 175% Gain

The work resulted in the development of 13 carbon fiber structures specifically designed to increase the rigidity of the 964 open-top chassis. These elements are bonded to the monocoque and tested to validate their effectiveness.

The result exceeds all expectations: 175% increase in torsional rigidity. Cabriolets and targas now match the dynamic performance of coupes. "That delicate balance between performance and weight is very familiar to us," explains Rob Gray, Technical Director of Red Bull Advanced Technologies.

The New 911 Carrera Cabriolet Reimagined

Along with this technical innovation, Singer unveils its new creation: the 911 Carrera Cabriolet Reimagined. Inspired by the widebody 911 Carrera Cabriolet models of the 1980s, it's limited to 75 examples.

The all-carbon fiber body reclaims the aesthetic codes of that era while integrating modern technologies. The LED headlights mimic those of the Series G but with a finer, more contemporary design. The 18-inch wheels take inspiration from the legendary Fuchs wheels of that era.

How Much Horsepower Under the Hood?

The 4.0-liter flat engine develops 420 horsepower. Developed with Cosworth, this naturally aspirated flat-six retains the air-cooling of the original block but adopts water-cooled cylinder heads. It features four valves per cylinder and variable valve timing, delivering smooth torque at low revs before unleashing full power above 8,000 rpm.

Power transfers via a revised 6-speed manual gearbox, sending drive to the rear wheels just like the original. The new Z-pattern soft top mechanism offers smoother operation than the original 1980s system.

Starting From What Price?

Singer hasn't announced pricing for this new limited series. Given the project's complexity, the Red Bull Advanced Technologies partnership, and the 75-example limitation, prices should easily exceed half a million euros. First deliveries are expected for 2027.

Two specifications are offered: Touring in Pacific Blue with a more refined approach, and Sport in Guards Red with a more aggressive body kit including widened air intakes and a fixed whale tail spoiler at the rear.

This collaboration between Singer and Red Bull Advanced Technologies marks a new milestone in the restomod art form, where Formula 1 expertise now serves to perfect icons of the past.
