Commissioned by long-term Singer client Scott Blattner in 2017, the Dynamics and Lightweight Study “DLS” project aimed to explore the ultimate potential of the 964-generation 911 platform through the extensive use of lightweight components. To realize this vision, Singer partnered with Williams Advanced Engineering—part of the Williams Grand Prix Engineering Group—leveraging their Formula One-derived expertise in aerodynamics, materials science, and vehicle dynamics. The project also benefited from the consultation of Porsche engineering legends Hans Mezger and Norbert Singer, bringing decades of air-cooled engine and aerodynamics experience to bear.
At the heart of the DLS is a bespoke 4.0-liter flat-six engine developed by Williams Advanced Engineering under Mezger’s guidance. This naturally aspirated powerplant produces 500 horsepower and features four-valve cylinder heads, titanium connecting rods, and a 9,000 rpm redline. Other cutting-edge technologies include dual-oil circuits, aluminum throttle bodies with carbon fiber intake trumpets, a CFD-optimized and enlarged engine cooling fan, and a carbon fiber airbox with an active multi-stage resonator chamber for mid-range torque optimization. A magnesium Hewland six-speed transmission handles power delivery to all four wheels.
Extensive use of carbon fiber, magnesium, and titanium throughout the car resulted in a svelte curb weight of just 990 kilograms. Brembo supplied lightweight monobloc calipers and carbon-ceramic rotors, EXE-TC provided bespoke damping, while BBS Motorsport crafted 18 inch forged magnesium center-lock wheels. Underbody and surface aerodynamics were optimized through CFD analysis by Williams, with input from Norbert Singer. The resulting package balanced tradition and state-of-the-art performance, introducing subtle alterations to the iconic 911 silhouette without compromising its timeless aesthetic.
Throughout its development, the DLS benefited from rigorous testing and refinement by an expert team, with automotive journalist and racing driver Chris Harris serving as a key development driver, working alongside Marino Franchitti to hone the car’s dynamics. Two Singer DLSs subsequently made their public debut at the 2018 Goodwood Festival of Speed—the first of just 75 planned examples, each meticulously crafted to its owner’s specifications. Delivering truly one-of-a-kind customization and an unparalleled driving experience, the Singer DLS represents one of the rarest and most sought-after Porsche 911 “reimaginations” ever created.
Offered here is an exceptionally well specified example of Singer Vehicle Design’s Dynamics and Lightweight Study, dubbed the “JAG Commission.” Beginning life as a 1990 911 Carrera 4, chassis number WP0ZZZ96ZLS403221 was reimagined in the bespoke shade of Fluid Silver, a $42,550 option, protected by Singer-installed full-body paint protection film ensuring the pristine finish remains unblemished. The exterior is also adorned with Titanium bead-blasted bright trim and a Platinum decklid badge which complement the Fluid Silver paintwork exquisitely.
The interior of the JAG Commission is a testament to Singer’s uncompromising attention to detail. The interior is trimmed in Black semi-aniline leather, complemented by custom fabric-to-sample Dedar Hermes Pavage Jacquard seat inserts and Titanium bead-blasted bright trim. The mid-trim package is leather-wrapped to match the rest of the interior, while the lower trim package is executed in Satin Black, completing the sophisticated monochromatic color scheme. Additional interior details include a carbon fiber X-brace painted in Satin Black, harnesses in Black, and premium door brightware. The tachometer features a Platinum face, and the shift knob is matched to the exterior brightware. Modern amenities are seamlessly integrated, including air conditioning, a heated front screen, and a Focal audio system. An optional axle lift system adds a welcome touch of practicality for everyday driving.
As one of only 75 DLS commissions undertaken, chassis number WP0ZZZ96ZLS403221 represents a rare and significant piece of modern automotive art. The odometer shows just over 1,200 miles at the time of cataloging, indicating this DLS has been preserved in like-new condition since its completion. The car benefits from a recent service performed in March 2024 at 813 miles, which included a thorough one-year service encompassing both engine oil and transmission fluid changes. The “JAG Commission” embodies Singer’s philosophy that “Everything is Important,” and offers a once-in-a-lifetime opportunity to acquire one of the most exclusive and meticulously crafted Porsche 911 reimaginations ever produced.
