And we want one. Desperately. Please can we have one? Please? Please!

Singer has unveiled its Dynamics and Lightweighting Study (DLS), produced in collaboration with Williams Grand Prix Engineering, at the Goodwood Festival of Speed. Suffice to say, it has the entire CarAdvice office drooling.

Power in the Singer DLS 911 comes from a 4.0-litre flat-six engine developed by Williams Advanced Engineering with input from the Hans Mezger, who has his fingerprints all over the flat-six that debuted in the 1963 911. In other words, he's well qualified in matters concerning air-cooled Porsches.

With 373kW on tap at a dizzying 9000rpm, lightweight throttle bodies and a unique oiling system, along with its own pistons, cylinders and titanium conrods, it's being pitched as the 'ultimate air-cooled 911' engine. We're inclined to agree, based on the information at hand. It's hooked up to a six-speed Hewland manual gearbox, by the way.

That sublime engine is housed in a body that has been completely overhauled. Singer says every single surface has been assessed using computational fluid dynamics, in search of more downforce and a slipperier overall shape than offered by the 964 base car.

Every panel is new, and every panel is made of carbon-fibre to save weight. The redesigned bodywork has also allowed Singer to house the engine further forward in the car, relocate some components to the front boot and deliver an overall stiffer product.

A redesigned oil cooler intake and front venting has eliminated lift on the front axle, while the roof shape and rear-window spoiler work with a modernised ducktail to up downforce on the rear axle. Ram air intakes in place of the rear windows work with revised louvres on the rear deck to improve cooling for the engine, too.

Under the skin, the car rides on a bespoke suspension developed in tandem with Williams Advanced Engineering. It's a lightweight multi-link, double-wishbone setup at the front end, and an aluminium trailing-arm setup down back, complete with integrated brake cooling. The dampers are remotely adjustable, too.

The wheels come from BBS Motorsport, and are made of magnesium with a high-strength titanium/aluminium centre lock. They're wrapped in Michelin Pilot Sport Cup 2 tyres measuring 245/35 up front and 295/30 down back, while braking is handled by a set of CCM-R carbon ceramic brakes from Brembo.

Finally, the interior, which is a gold-trimmed tribute to lightweight design. There are lightweight carbon-fibre seats designed specifically for this car by Recaro, while the Momo steering wheel is also a one-off. The gearshift has an exposed linkage, and the entire dashboard has been crafted from carbon.

“The Dynamics and Lightweighting Study has been years in the making," said Rob Dickinson, founder of Singer Vehicle Design. "To see the results, representing the ongoing pursuit of our client’s vision for their ultimate air-cooled 911, is so exciting."

We’ve worked relentlessly to present a machine that visually celebrates the past while acknowledging the future – both inside and out. It’s our fourth year at this incredible event and we’re thrilled to be back at Festival of Speed for its twenty-fifth anniversary, and to wish Porsche a very happy 70th birthday.”
