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.
