Finally, at this year’s Frankfurt Motor Show the Porsche 918 Spyder will celebrate its debut as a series production car. So far all the numbers we’ve been told about the car’s power and performance belonged to test prototypes. But now we have the final, confirmed specifications here.

And they are remarkably bold. The production Porsche 918 Spyder is not as powerful as its main rivals – LaFerrari and McLaren P1 – but then Porsche says this is super a sports car designed for everyday use. It is like a 911 on steroids. It has the capability to run on pure electricity. And, should you feel like it, it can achieve mind-boggling speeds.

The production Porsche 918 Spyder boasts a total of 887 horsepower from its plug-in hybrid V8 powertrain. The V8 engine is basically a racing block from the RS Spyder Le Mans racer, and it is boosted with two electric motors, which makes the car four-wheel-drive. The system is managed by an electronic brain that, left to its own devices, can choose the best driving mode depending on your driving style. Alternatively, you can override the computer and select the mode you want.

So if you think about it, you can drive around the city in pure electric mode in utter silence, emitting nothing harmful at all. Then, when you reached the outskirts of the town, flick the switch and put it in Hybrid or Sport, and enjoy the fury of all that horsepower.

Porsche 918 Spyder can accelerate from 0 to 100 km/h in 2.8 seconds. The top speed is around 325 km/h, which is not as fast as the P1 and LF’s 350, but still plenty enough. The best thing bout the 918 is its fuel economy: 3.0 l/100 km or 94 imp mpg. Although in reality you probably won’t be able to do better than 75 mpg, which is still brilliant. The range in electric mode is 25 km.
