Singer Vehicle Design has collaborated with Williams Advanced Engineering to produce a 500bhp 964 Porsche 911 that benefits from Formula 1 technology with a completely bespoke powertrain and lightweight body.

On show at the Goodwood Festival of Speed, this ‘reimagined’ 911, produced as part of California-based Singer’s Dynamics and Lightweighting Study (DLS), has a full carbonfibre body and enhanced torsional stiffness that's possible thanks to a full weight-down study by Williams.

Described as the “most advanced air-cooled 911 in the world”, the car uses a bored-out version of the 964’s 3.6-lite flat six, now of 4.0 litres, and which has been shifted forward to improve the car’s weight distribution. The motor, co-developed by Williams and Porsche engineering legend Hans Mezger, has titanium valves and produces its peak power when spinning at 9000rpm. It features lightweight components made from magnesium, an optimised lubricating system and F1-inspired fuel injectors.

Drive is sent to the rear wheels via a unique six-speed manual gearbox that has magnesium casings and hollow shafts to further reduce the powertrain’s rotating mass. The gearlever is raised and has an exposed titanium and magnesium linkage, while shift lights are integrated into the tachometer.

The powertrain is supported by anti-lock braking system, traction control and electronic stability control technology produced for the DLS by Bosch, enabling switchable driving modes, including one that turns all electronic assistance off.

The car uses lightweight multilink and double wishbone front suspension, while the rear features an aluminium trailing arm that features an integrated brake cooling set-up. Damping is handled by bespoke shock absorbers that have remote reservoirs.

Porsche 911

Does Porsche's decision to introduce turbochargers across the 911 range damage its heritage? Or is the foundations of a new era for the supercar you can use everyday?

Back to top

Brembo has supplied carbon-ceramic discs and monobloc calipers specifically for the DLS 911 that are claimed to be capable of both road and track work. They’re located behind magnesium, monobloc 18in wheels developed by BBS with Williams-produced titanium centre locks. Michelin has provided the Pilot Sport Cup 2 rubber.

Inside, Singer has fitted the cabin out with a detailed mix of custom leather trim and carbonfibre panels, with the Recaro seats and Momo steering wheel produced in bespoke lightweight forms specifically for the car.

The DLS project began in November 2017 when Porsche enthusiast Scott Blattner requested his 1990 964 to be given lighweight and performance enhancements. His car will be displayed alongside several other bespoke Singer commissions, including ones for customers in London, Manchester and Surrey.

 Looks great, but what does it cost?

Aside from some garish internal features, and having wheels that are a little too big and tyres that are too low profile, this is much more appealing than any of the current non-turbo turbo 911s.

I always think it hard to make a business out of engineering services like Williams and Lotus. Companies always do it themselves when they can and you need to be on the edge. But good luck to them..

Some of the other Singers look better and the Stephens ones too at a fraction of the price albeit with lower finish levels.

Looks beautiful. The perfect blend between old and new. Now if only they could do the same thing to the 246GT Dino.

Compared with Porsche's own 911 Speedstar concept (see another article) this remains nothing more than an after-market conversion with poor (but no doubt expensive) detailing, so much so that the car in the third picture looks like a 1:18 scale diecast. The thickened window trim looks particularly awful.

...that technical specification should excite any petrolhead.

What's the attraction other than maintaining an historical link?

Surely air-cooled engines are inherently less powerful and efficient due to the absence of temperature control, noisier and do not provide good cabin heating. Even motorcycles have all but abandoned it.

Maybe this new engine is really oil-cooled and the air-cooling is incidental.

That aside, this car must surely be a one-off, since it must breach Porsche IP rights? 

13 July 2018

Tuners can do as they please with Porsches, or any car for that matter. It's all about how it's marketed that Porsche would be worried about.

I understand Singer has an arrangement for a very specific naming strategy that is approved by Porsche, they have to use the word 'reimagined' in there. The cars are still taxed as a Porsche and the structure is still the original car, although heavily reworked, so they still carry the nose badge.

 Go on then, tell the nice People how much one would cost!, I’ll tell you....£1.8 Million!, no, that’s not a typo....,
