Singer has taken the wraps off its new Dynamic and Lightweighting Study (DLS) at the Goodwood Festival of Speed, billing the "client-inspired" collaboration with Williams Advanced Engineering as the "most advanced air-cooled Porsche 911" in the world.

The DLS employs a recently developed 4,0-litre flat-six engine from Williams, delivering 368 kW to the rear wheels via a Hewland six-speed manual gearbox. Furthermore, the model receives a comprehensive aero kit that includes various lightweight components.

Singer says it eliminated front axle lift thanks to a redesigned front oil-cooler intake and ventilation, as well as a new front splitter. The ducktail spoiler also received some attention, while the roof-channel and rear window spoiler work with the diffuser to produce additional downforce. The engine air intake and cooling was also optimised with the fitment of a side-window ram-air intake and rear deck-lid venting.

In addition to the overall mass being reduced, Singer says the weight balance was optimised thanks to the repositioning of the engine as well as the implementation of a full carbon-fibre body. Torsional stiffness was also increased.

Meanwhile, the ABS, traction control and stability control were recalibrated by Bosch, and selectable driving modes added.

Interior components unique to the DLS include a set of lightweight carbon-fibre seats from Recaro and a steering wheel from Momo. The manual gear-selector has been raised while the carbon and titanium pedals have been drilled to further cut overall mass.
