Just last year, Singer and Williams began developing a highly modified Porsche 911 under their Dynamics and Lightweighting Study. Well, it is finally here, and Singer unveiled the first two restorations from this venture at the Goodwood Festival of Speed in mid-July. The two cars are a 1990 911 in white, and a 1989 911 in red, both of which are incredible to behold.

Both cars are powered by 4.0-liter, air-cooled flat-sixes in true vintage Porsche fashion, churning out an impressive 500 horsepower without the help of forced induction. Unlike most production air-cooled Porsche engines, these feature dual overhead cams with four valves per cylinder, which are of course made from titanium, and works alongside magnesium throughout the engine to keep things light.

The car is aerodynamically optimized, with small air channels at the rear window designed to direct air to the ducktail spoiler and diffuser, creating usable downforce. The engine takes in air through two ram-air intakes that are integrated into the quarter windows, and a vent in the spoiler helps expel excess air.

Everything on the cars are designed with lightness in mind. The seats, steering wheel, and much of the interior trim is made from carbon fiber. Brakes are carbon-ceramic Brembo units with monoblock calipers, and the wheels are custom-made BBS center-locks designed to look like period-correct Fuchs alloys.

The suspension was designed by Williams, and features remotely adjustable dampers. The tires are Michelin Pilot Sport Cup 2s in a special size to fit the BBS wheels. Something that many will be happy to see is the six-speed manual designed by Hewland. No automatic or dual-clutch nonsense here.

75 clients will be able to purchase these special vehicles, and we can only speculate on how astronomical the price of something so special will be.
