Porsche 918 Spyder enters production
Limited to a production run of 918 examples, the 918 Spyder costs £657,400 in the UK, though rises to £718,000 if ordered with the optional 'Weissach' performance package, which features track oriented kit such as racing seat-belts and flame-resistant upholstery, as well as additional aero attachments, a unique body wrap (in place of a paint finish) and the deletion of some interior comforts offering a small weight saving.
The 918 Spyder is amongst a new breed of hybrid petrol-electric supercars, which use their on board electrical gubbins to provide extreme performance but also astonishing official MPG and CO2 figures.
It is fitted with a 4.6-litre naturally aspirated V8 engine, developing 599bhp. This is bolstered by two electric motors that take total power to a dizzying 875bhp.
However, thanks to being able to run for short distances on electric power alone, the 919's official CO2 rating is a Toyota Prius beating 70g/km, and it will return 94mpg on the combined cycle.
The 918 faces stiff competition from its traditional rivals McLaren and Ferrari, both of which are getting ready to start production of their own hybrid supercars, the P1 and LaFerrari respectively.
If you fancy your own 918 Spyder, you'd better be quick – Porsche has said that two thirds of the production run has already been snapped up.
