The 214mph petrol-electric hybrid two-seater is planned to be built in a run of no more than 918 examples, in left-hand drive only, over the next 18 months.
With a price tag of £657,400, Porsche claims orders for its new performance flagship are ahead of expectations. “We have taken deposits for more than two-thirds of the planned production volume,” officials revealed to Autocar. “Interest is increasing by the day.”
First revealed as a concept car at the 2010 Geneva motor show, the 918 Spyder is based around a carbonfibre monocoque, comes clothed in composite plastic body panels and uses a bespoke chassis fashioned from aluminium, magnesium and titanium.
This combination has helped Porsche achieve a kerb weight of 1634kg for the 918 Spyder in its lightest form, despite the inherent complexity and bulk of its petrol-electric hybrid powertrain and battery pack.
Removable roof panels that stow away in the nose section allow the new Porsche to be used either as a coupé or a roadster, while an optional Weissach performance package, which raises the overall cost of the car to £718,000, brings a series of aerodynamic tweaks. These include winglets to the bumpers for added downforce, as well as a number of lightweight components, including magnesium wheels, that combined to reduce the kerb weight by 35kg over the standard model.
The 918 Spyder is powered by a plug-in petrol-electric hybrid drivetrain based around a mid-mounted, naturally aspirated 4.6-litre V8 petrol engine that produces 599bhp at 8700rpm. It is supported by two electric motors, one sited up front within the front axle and another at the rear, developing a combined 282bhp at 6500rpm.
