Removing the roof from a performance car has always come with consequences, but Singer Vehicle Design refuses to accept compromise—especially when its reimagined Porsche 911s now push supercar money and power.
To solve the age-old problem of flex in convertibles, Singer turned to an unlikely ally: Red Bull Advanced Technologies.
With demand rising for turbocharged flat-six Singer commissions in Cabriolet and Targa form, structural rigidity became non-negotiable.
How Singer Enlists Red Bull for Enhanced Structural Integrity
Red Bull’s engineers applied the same simulation and structural analysis techniques used in top-tier motorsport, deploying Finite Element Analysis to compare Singer’s coupe and open-roof cars.
The goal was simple but ambitious: eliminate the dynamic penalties traditionally associated with drop-tops, particularly those rooted in 1990s-era chassis design.
The solution is as discreet as it is dramatic. Thirteen bespoke carbon-fibre reinforcement structures are bonded directly to the restored Porsche 964 monocoque, boosting torsional rigidity by a claimed 175 per cent.
According to Singer, the result is an open-roof 911 that matches the coupe for handling precision, braking stability, and overall refinement—without a meaningful weight penalty.
Singer’s Chief Strategy Officer Maz Fawaz describes the collaboration as a natural extension of the company’s philosophy: blending heritage with cutting-edge engineering in pursuit of perfection.
For buyers spending seven figures on a car that looks resolutely analogue, it means enjoying top-down thrills with none of the usual drawbacks. Just don’t expect donor 964 Cabriolets to stay affordable for long.
