Singer has unveiled a Cabriolet variant of its wide-body Carrera reimagination, inspired by the pumped-up G-series convertibles that allowed 1980s Porsche buyers to have Turbo looks without the lag. Limited to 75 cars, it features chassis reinforcements developed by Red Bull Advanced Technologies, adding a new entry to Singer's little black book of F1 teams.

Slung over the rear axle is Singer's Cosworth-developed, naturally aspirated 4.0-litre flat-six with variable valve timing. Good for 414bhp, it revs beyond 8,000rpm and features air-cooled cylinders with water-cooled heads – a hybrid approach that preserves the flat-six's classic induction bark while meeting emissions standards.

The carbon fibre bodywork references Porsche's Super Sport Equipment package: flared arches, a deep chin spoiler, and of course, the optional whale tail. Mirroring this, the lucky 75 can specify both a fixed and active rear wing – delivered in a bespoke flight case – permitting them to rotate between the two.

Singer has also modernised the roof mechanism, shedding bulk both in terms of design and mass, granting what it calls the best access yet to the flat-six's soundtrack.

Like the Coupe, pop-up auxiliary driving lamps are fitted to the bonnet. These are high-performance spotlights that rise when activated and fold flush when not in use, rather than concealed main beams in the Slantnose tradition. It's a Singer flourish that could upset the purists, but we think they've pulled it off.

Beneath the carbon weave sit 13 carbon fibre reinforcing structures developed by Red Bull Advanced Technologies, bonded to the 964 monocoque to compensate for the missing roof. Torsional rigidity increases by 175% – enough, according to Singer, for the Cabriolet to handle like the Coupe without wholesale re-engineering.

To complete their mission, RBAT scanned the 964 chassis and built a finite element model, refining it against physical testing until the simulation matched reality. This pinpointed where the cabriolet was working hardest under torsion, and where reinforcements would be most effective.

Making the most of the additional strength are four-way electronically adjustable dampers from Singer's turbocharged programme and five driving modes, while the chassis mods extend to a front-axle lift. The painfully pretty Fuchs-style 18-inch centre-lock wheels wear Michelin Pilot Sport tyres, with carbon-ceramic brakes also available.

Naturally, the interior is fully customisable. Air conditioning, navigation and CarPlay are all integrated, and Singer has used the cabriolet to introduce stitched and burnished leather seams to the cabin. A choice of sports or racing bucket seats are available, and in front of the driver sits the classic 911 dial layout featuring details that would shame many Swiss watch manufacturers. The more aggressive of the two contrasting launch examples is finished in Guards Red dressed with the fixed rear wing, sports-focused front splitter and an interior of Ink leather with Interferenza cloth. The second model is Pacific Blue with the active rear wing, touring-focused front splitter and a Tangerine interior with stitched and burnished leather seams.

As ever, the price to commission your own remains undisclosed. And if the Coupe or Cabriolet isn't your thing, expect a Targa variant to follow in the near future.
