Singer and Williams Build Bantamweight Porsche 911

This Custom Porsche 964 pushes the boundaries of lightweight design and packs 500 horsepower.

Earlier this year, Motor Authority reported on the lightweight, 500-horsepower, 4.0-liter engine that Singer and Williams were building. Now, Singer has released details on the Porsche 911 that’s wrapped around it. Say hello to the lightweight Singer-Williams 964.

Regular client Scott Blattner asked Singer to build the car. The famous Porsche modifiers called Williams Advanced Engineering, a subsidiary of Williams’ F1 team, to work on the engine.

Williams started with a period-correct 3.6-liter 964 flat-six engine, which they massaged into 4.0 liters. To reach the 500-horsepower target, Williams hired Hans Mezger.

Metzger built many of Porsche’s race engines, including the first flat-sixes. His design work resulted in a 24-valve air-cooled engine that will scream a delightful naturally-aspirated tune at 9,000 rpm.

The Williams engine may utilize a classic design, but they applied modern composites to substantially reduce weight. That means titanium connecting rods, aluminum throttle bodies, carbon fiber intake trumpets, and a titanium exhaust, among other modifications.

This Singer pushes the design envelope all around. Beyond aesthetics, there’s a redesigned undertray to improve aerodynamics (Williams helped with that, too). In addition, Singer used lightweight materials like titanium and carbon fiber everywhere they could. The curb weight is just 2,180 pounds.

The paint color is called Absinthe Green. And while Singer missed an opportunity for pink elephants inside, the Blood Orange upholstery looks magnificent. Massive fender flares exaggerate the lowered stance, housing magnesium 18-inch Fuchs wheels that bear specially-designed Michelin Pilot Sport Cup 2 tires.

The adjustable suspension comes from lightweight materials. Plus, Brembo calipers and carbon-composite rotors should give Blattner a car ready to rip up canyon roads or red-and-white curbing with ease. As proof that none of this comes cheap, Singer even went so far as to hire driver Marino Franchitti and racing journalist Chris Harris to shake the car down. After all that, we think it’s ready to go.
