The 918 Spyder will come with 770 horsepower and will be capable of doing around 78 mpg, thanks to its 4.6 liter v8 engine and two electric motors, it will have a top speed of over 200mph.Porsche have yet to announced how much their new 918 Hyrbid Spyder will retail for, but we suspect this could be one of Porsche’s most expensive cars to date.
