Singer has unveiled a customized restoration of the 911 DLS.

Porsche 911 restoration specialist Singer and Williams Advanced Engineering, the technical arm of the Williams F1 team, had their jaws drop in unison in 2017 when the two companies announced a "Dynamics and Lightweighting Study," or DLS for short, and collectively dropped their jaws when they unveiled an improved version of the 964-generation 911, known as the DLS.

The project originally began when Singer client Scott Blattner challenged the company to find a way to reduce the weight of the 964 911 while improving performance. Singer did not shy away from the new project and had Williams Advanced Engineering inject its F1 know-how into the project.

Seeing a potential market for the car, Singer decided to give 75 more cars the DLS upgrade. These are now being produced at Singer's facility in the UK (the company also has a facility in California), and the first car was completed earlier this week.

The car is based on a 1989 Porsche 911 and is finished in a shade called Oak Green Metallic. The engine was developed by Singer and Williams, with advice from Hans Metzger (a Porsche engineering veteran), who worked on Porsche's early flat-six designs and many racing powertrains.

Weight reduction. Singer and Williams optimized aerodynamics and developed a new underbody incorporating magnesium, titanium, carbon fiber, and other advanced materials to reduce the final vehicle weight to just 2,180 pounds. The lightweight suspension design also improved suspension geometry and increased adjustability. During the development process, racer Marino Franchitti and automotive journalist Chris Harris helped fine-tune the car's driving feel.

Interestingly, Singer has a new 911-based study that is much wilder than the DLS. Called the All Terrain Competition Study, or ACS for short, it is best described as a wild off-roader similar to the Porsche 911 SC safari rally cars of the 1970s. With any luck, this study will also be produced.
