Porsche has released final details of its long-awaited 918 Spyder - three years after it was first shown as a concept car.
The Spyder combines a 4.6-litre race-bred V8 engine with plug-in hybrid motors for a total of 661kW of power and 1275Nm of torque.
Porsche's rival to the Ferrari LaFerrari and McLaren P1 can drive on electric power alone at speeds of up to 150kmh, and the manufacturer claims fuel efficiency of 3.0-3.3L/100km.
The car has a battery-only range of 31km before its petrol engine takes over.
A 95kW electric motor and 447kW V8 drive the rear wheels through a seven-speed dual-clutch transmission, while the front wheels are linked to a separate electric motor.
Fairfax Media tested a prototype of the 918 Spyder earlier this year.
The Spyder will only be built in left-hand-drive though determined collectors may be able to acquire cars for racetrack purposes only.
The car was revealed at the 2013 Frankfurt motor show overnight (NZ time).
