Singer DLS 1990 Porsche 911 is classic sports car re-imagined for the modern times

A classic Porsche evolved and optimized by modern engineering techniques and technologies – this is the Singer DLS Porsche 911. Taking part at the highly prestigious 2018 Goodwood Festival of Speed, the new Singer DLS Porsche 911 is a bespoke creation by Singer Vehicle Design and Williams Advanced Engineering that boasts of more power yet lower weight that the model it was based on.

It all started when a customer named Scott Blattner approached Singer Vehicle Design and asked the company to not just restore but also re-imagine his 1990 Porsche 911 (964 Generation) as a more powerful yet lighter sports car. Sensing it needs help for this one-of-a-kind project, Singer approached Williams Advanced Engineering. The collaboration between Singer and Williams to come up with a bespoke creation started around two years ago. Eventually, Singer and Williams, along with former Porsche engineers Norbert Singer and Hans Mezger as well as other technical partners, worked hard to re-imagine the 1990 Porsche 911.

In the process, the partners decided into inject into the project car a number of alluring features. Thus, from a standard two-wheel drive 1990 Porsche 911, born was Singer DLS Porsche 911. The DLS stands for Dynamics and Lightweighting Study, which appropriately conveys the fact that the DLS Porsche 911 is more powerful and weighs lighter than the original model. As it is, the 1990 Porsche 911 is powered by an engine that delivers 247 hp, and weighs around 3,031 lbs. The DLS Porsche 911 has become more than twice as powerful as the original model and around 850 lbs lighter – with output and weight pegged at 500 hp and 2,180 lbs, respectively.

Interestingly, the restoration and modification developed and used for Blattner’s 1990 Porsche 911 can also be applied on other 911 models, effectively transforming them into a DLS. In fact, a 1989 Porsche 911 received the same treatment, and is also displayed at Goodwood in the Michelin Supercar Paddock. Displayed outside the Goodwood House, Blattner’s 1990 Porsche 911 was wrapped in Parallax White with Norfolk Yellow interior. The 1989 Porsche 911, meanwhile, is finished in Heart Attack Red with Black interior.

While the engine of the Singer DLS Porsche 911 remains a normally aspirated, air-cooled Porsche flat-six, Williams and Mezger reworked it to feature twin overhead cams, four titanium valves per cylinder. Made of magnesium and other lightweight materials for lower mass, this 4.0-liter engine employs lightweight throttle bodies with F1-style upper and lower injectors. The result was what earlier mentioned – output surged from 247 hp to 500 hp, as available at just 9,000 rpm.

Williams also collaborated with Norbert Singer to fully rework the aerodynamics of the 1990 Porsche 911, employing computational fluid dynamics (CFD) analysis to re-assess every surface of the car. As a result, the front oil-cooler intake and venting were redesigned and a new front splitter was installed, effectively getting rid of front axle lift.

Furthermore, the new Singer DLS Porsche 911 features the ducktail spoiler of the 2.7 Porsche RS Carrera. The optimized ducktail and diffuser, as well as the roof-channel and roof/rear-window spoiler all work to generate greater downforce at the rear section.

The Singer DLS Porsche 911 rides on center-lock 18-inch BBS monoblock forged magnesium wheels shod with specific Michelin Pilot Sport Cup 2 tires. The bespoke car sits on lightweight double wishbones in front, and aluminum trailing arms in the rear. Stopping power comes in form of specially developed Brembo carbon ceramic brakes and monobloc calipers.
