Last month, renowned Porsche restorer Singer unveiled its most ambitious project yet. Developed in collaboration with Williams Racing, the Singer Dynamics and Lightweighting Study (DLS) is quite simply the most advanced air-cooled Porsche 911 ever created. It was first shown at the Goodwood Festival of Speed, and now the lightweight show car is finally making its American debut, as Singer will be presenting the 911 DLS at the Pebble Beach Concours d'Elegance on August 23.

Under the hood is a sublime-sounding, naturally aspirated flat-six stuffed inside a 1990 Porsche 911 964 that develops around 500 hp at 9,000 rpm. The 911 it's based on may be nearly 30 years old, but just about every component has been updated to reduce the weight and improve the aerodynamics. Extensive use of magnesium and lightweight materials reduced the mass of the engine, and the car also features a full carbon fiber body and enhanced torsional stiffness.

Thanks to these modifications, the car only weighs 2,182 pounds. Other bespoke parts include Brembo CCM-R carbon-ceramic brake discs, Michelin tires, and BBS 18-inch forged magnesium wheels. With all these modifications, it's no wonder the Singer Porsche 911 DLS has an eye-watering $1.8-million asking price. Trust us, photographs don't do this incredible car justice - you need to see it in the metal, so be sure to head on down to Pebble Beach this month.

"This year marks a series of milestones for Singer Vehicle Design," said Singer founder Rob Dickinson. "Not only are we celebrating our 10th year of business, but we have delivered our 100th commission and are now able to present the results of the Dynamics and Lightweighting Study – undertaken with an alliance of iconic partners. We are humbled and honored to be shown upon the world stage at the Pebble Beach Concours – marking a continued global presence for Singer."
