Singer Vehicle Design restores this Porsche 911, giving it 500 horsepower but with less weight

Article by Christian A., on November 15, 2017

Singer Vehicle Design is one of the few companies that have a reputation for making some of the coolest machines out there, including the air-cooled Porsche 911s. They collaborated with Williams Advanced Engineering, which is popular for having injected some pretty advanced technology into the classic coupes, further improving these cars’ performance. The image you are looking at now is that of the very first model to benefit from these improvements, finished in an Absinthe green exterior, contrasted with the Blood Orange leather covering the cabin.

The owner of this car is a guy named Scott Blattner who asked for his 1990 Porsche 911 to be a lighter but more powerful car. Because of this, the tuner worked with Williams Advanced Engineering so that they could focus on the dynamics and the study to produce an extremely lightweight car. Overall, the reimagined 911 only weighs a total of 2,180 pounds (990 kilograms), despite the fact that it carries a 4.0 liter naturally aspirated flat-six engine that packs 500 horsepower (372 kilowatts), and is capable of revving to over 9,000 rpm.

Rob Dickinson, founder of Singer said in his statement that it took them a lot of effort to combine services to highlight both “bewitching individual componentry” with a “viscerally compelling driving experience”.

The classic 911 now has a smoother body, with the use of lightweight components like magnesium, titanium, and carbon fiber. Its suspension has also been tweaked and now has features like better geometry and improved adjustability compared to the original setup.

The tuner also teamed up with a number of suppliers to get the best parts to keep a tight rein on the weight of the restored 911. One of these is the set of BBS contributed forged magnesium 18-inch wheels, covered in the Michelin Pilot Sport Cup 2 tires. The wheels are completed with a set of Brembo monobloc calipers and carbon composite rotors that handle the car’s braking. Another supplier they got was Hewland, for the six-speed manual gearbox that was made with magnesium.

Of course, singer made sure that this restored lightweight 911 can perform well too, and that is why they formed an all-star team for the best driving machine imaginable. In fact, among the people they consulted on how to perfect the car’s driving feel are Marino Franchitti (a racer) and Chris Harris (a journalist).

Singer had always been different compared to other existing shops in California, in that they will perform the car restorations on the Williams campus in Oxfordshire, England. Singer decided to start accepting 911 units to be reimagined, but they will only limit it to 75 units - we just don’t know if that’s per year, or if that’s the grand total. Lastly, they also mentioned that their clients will be able to spec the coupe before it goes through a major makeover.

Press Release


As announced in August 2017, Singer client, and Porsche enthusiast Scott Blattner, requested lightweighting and high-performance enhancements for his 1990 Porsche 964. To meet the goals defined in collaboration with Scott, Singer undertook a Dynamics and Lightweighting Study “DLS” with Williams Advanced Engineering – part of the Williams Grand Prix Engineering Group. As a result, Singer engaged Williams and a formation of technical partners to engineer a selection of restoration and modification services strongly oriented toward lightweighting and dynamic gains.

Singer clients and renowned Porsche collectors, Jan Koum and Mark Evenstad joined the initiative, offering their support and interest in enhancing their Porsche 964s with motorsport inspired material science and technology.

Scott explained:

“The guys at Singer have always been receptive to the question “What if?” So, the question became…what if Singer worked on restoring and modifying my beloved 27-year old Porsche 964, with the assistance of an engineering concern born from the world of F1. How would such a car look and how would it perform?”


The result is a new selection of restoration and modification services, known as DLS [Dynamics and Lightweighting Study] - collaboratively developed by Singer, Williams Advanced Engineering and a collection of world-renowned specialists such as Michelin, Brembo, and BBS Motorsport.

Porsche legends Norbert Singer, and Hans Mezger participated as special consultants bringing years of wisdom and guidance in the areas of aerodynamics and engine development.

Racing driver Marino Franchitti together with automotive authority and journalist Chris Harris are serving as consultants and vehicle dynamics development drivers, working in close collaboration with Williams Advanced Engineering’s dedicated vehicle development team.

Details of the first machine, owned and commissioned by Scott Blattner, incorporating the Dynamics and Lightweighting Study are now being revealed. The car is presented in Absinthe – a color unique to the study – with interior leather in Blood Orange.

Study Details

Through intense study and component development for the 964 platform, advances in the following areas have been commissioned by Singer’s clients and achieved in collaboration with Williams Advanced Engineering:

A Porsche four-valve, four-camshaft, naturally aspirated, 500HP air-cooled flat-six engine developed by Williams Advanced Engineering with consultation by Hans Mezger.
Underbody and surface aero performance optimized through CFD analysis, by Williams Advanced Engineering, with consultation by Norbert Singer.
Improved suspension philosophy including light-weighting, enhanced geometry and improved adjustability
Further weight reduction methods and use of magnesium, titanium, carbon fibre and other advanced materials contributing to a minimum vehicle weight of 990kg / 2180Ib.
Additional advances have been achieved for the commissioning owners through unique and exclusive content, in concert with technical partners including:

Michelin - Bespoke Pilot Sport Cup 2 tires
BBS Motorsport - Lightweight 18” forged magnesium, monobloc, centre-lock wheels
Brembo - Lightweight, monobloc calipers and carbon composite rotors [CCMR] braking
Hewland - Magnesium, lightweight 6-speed transmission
EXE-TC - Bespoke damping

Singer Vehicle Design Founder and Creative Director Rob Dickinson said:

"On a technical level, the study has been fascinating and has resulted in an incredible restoration with the benefit of top drawer resources and modern science. Artistically it has been a second chance to connect with the machine on a new level.

“Aesthetically, I've been working closely with friend and creative sparring partner Daniel Simon and a great team here in California to present ideas that work functionally as well as emotionally for our clients.”

The results of this two-year study and development effort represent a relentless pursuit of excellence through a lightweight and artistic philosophy and attempt to celebrate an era of lightweight, air-cooled Porsche 911s that targeted ultimate performance on road and track.

Chris Harris, who has driven every fast road car on the planet and pretty much every significant Porsche, said: “I’m not an engineer by trade, but just look at the list of clever people around me and you’ll see that’s no great problem. I’m here for two reasons: to help define how the car drives, how it feels - how it will interact with each of the lucky owners. And to document the entire process from start to finish. Rob, Maz and the team are visionaries in this space, and this is a once-in-a-lifetime project. Just thinking about the finished machine makes me grin.”

Commissioning and Cost

The Dynamics and Lightweighting Study has been presented to Singer’s current client base and the first commissions that have already been taken are commencing in due course.

Costing of these restorations has been dependent on the client’s wishes and further details can be discussed with Singer.

As is normal practice, Singer will work closely and collaboratively with each owner to accommodate their unique vision for their lightweight machine – whether it be stripped bare for dynamic savagery, dressed for intercontinental touring or pitched somewhere between those extremes.

The restoration and modification of these client owned cars will take place in the U.K. at a dedicated Singer facility housed on the Williams campus at Grove in Oxfordshire - to be known as Singer at Grove.

Craig Wilson, Managing Director of Williams Advanced Engineering, noted: “Being able to work with the classic Porsche 964, applying our expertise in aerodynamics, advanced lightweight materials and vehicle dynamics to optimise performance has been a tremendous opportunity. We are delighted that the restoration of these cars for Singer’s clients will take place here in Oxfordshire.”

Background and Client Perspectives

Mazen Fawaz, Managing Director, explained: “As is often the case at Singer Vehicle Design, we picked up the phone to companies whose reputation precedes them and explained the challenge. The response has been overwhelmingly positive. We found a group of petrolheads, full of enthusiasm to help us with state-of-the-art design and materials. This restoration showcases some truly incredible engineering from around the world.”

Marino Franchitti, whose extensive history of race wins includes the 12 Hours of Sebring, in addition to thousands of miles in both road and racing 911s of several generations, said:

“To be part of this effort with the resources and partners we have is the stuff of dreams, especially for an air-cooled fan like me. Everyone is working so hard to bring that Singer magic to these restorations and what I’ve seen and experienced behind the wheel has me very excited.”

Scott Blattner noted further: The results as applied to my car are extraordinary and we felt compelled to share with other enthusiasts exactly what this company is capable of when given the funds and the partners to excel at the highest level - we are all excited to be part of what we hope is a strong group of believers in this effort.”

Mark Evenstad provided further perspective, saying: “As an insatiable driver and reluctant collector, my cars get driven hard, daily. As a massive fan of Singer through my previous restoration I still had appetite for more. A big part of the Singer magic for me has always been their ability to listen, understand the experience I’m chasing from my cars and then go push the boundaries for me. This was an incredible opportunity to bring race-bred expertise and an incredible group of automotive luminaries together in order to rise to a challenge. It’s hugely exciting to share these first details of a restoration and invite a small group of others to join us.”

And Jan Koum noted: “Scott, Mark and I have each commissioned restorations from Singer Vehicle Design in the past. Pursuing further advances in light-weighting and dynamic response for our Porsche 964s is a logical next step for me.”

Rob Dickinson said: “We thank Scott, Jan and Mark for giving us an amazing opportunity to further honour the car we love. We have listened to three of our most valued clients and endeavoured to satisfy their requests for more performance. Through a long and herculean effort, we’ve come up with a combination of services to showcase both bewitching individual componentry and a viscerally compelling driving experience. It also proves – if any proof were needed - the enduring relevance and genius of Porsche’s evergreen air-cooled 911 in the 21st century.”

In closing remarks Dickinson revealed: “I think we've all been aware of history looking over our shoulder during this time, especially consulting with Messrs Mezger and Singer. It's felt at times like a monumental responsibility to our clients as we have pushed the boundaries of this air-cooled icon in a manner that may never be repeated. Noble material science bestowed upon a legend - long live the Porsche 911.”
