Production of the Porsche 918 Spyder begins at the firm's Zuffenhausen factory today.
First deliveries are expected before the end of the year.
UK prices start at £657,400, rising to £718,000 if equipped with the optional Weissach performance package. Porsche says orders for the initial limited run of 918 examples have already exceeded expectations, and two thirds of the planned production run is already booked. Porsche directors gave the green light for production following 2000 declarations of interest in 2010.
