Speaking to journalists at the UK media preview of the new 981 series Cayman, Porsche GB product manager Jim Willows has said the forthcoming 918 Spyder will have a C02 average of just 70g/km C02.

This additional model for the Porsche range will be the company’s new flagship when it goes on sale in the fourth quarter. The model name refers to both the 18 September 2013 start date for production, as well as the number of cars that will be made at the Zuffenhausen works.

This hybrid supercar will be based upon the 918 Spyder plug-in concept which premiered at the Geneva motor show in March 2010. The prototype was powered by the combination of a 375kW 3.4-litre mid-mounted V8 and two electric motors. Combined output was stated as more than 530kW. The 0-100km/h time was quoted as 3.2 seconds.

The production car’s V8 will be a 4.6-litre V8 with dry sump lubrication, the company revealed in September 2012. Total power will be 770hp* thanks to the combination of the 570hp V8, supplemented by a 90kW hybrid module on the rear axle and an 80kW electric motor on the front axle. The range in EV mode will be 25km.
