The model is a result of a dynamics and lightweight study carried out with Williams that intended to help meet Singer clients' demand for more power, lighter weight and more hardcore dynamics.
To achieve 493bhp from the car’s original 243bhp, Singer has bored out the Porsche’s original 3.6-litre flat-six engine to 4.0 litres and increased the car’s redline to 9000rpm. The engine was revealed last year, but the full car has just made its online debut. No performance figures have been released.
The car weighs in at 990kg, thanks to a body and chassis largely made of carbonfibre, titanium, magnesium and aluminium. Lightweight mechanical components also help to keep the weight down, including magnesium and titanium for the camshafts and cylinder heads.
The car rides on Fuchs-like centre-locking 18in magnesium wheels shod with bespoke Michelin Pilot Sport Cup 2 tyres. The Hewland six-speed gearbox is also magnesium, while the brake discs are carbon composite units with Brembo calipers.
The blood orange and absinthe body colours extend to the interior, which has orange leather-trimmed bucket seats and exposed bodywork.
The development drivers are Marino Franchitti and Top Gear presenter and former Autocar staffer Chris Harris. The cars are being built at Williams’ Oxfordshire base in their own build facility.
