Porsche unveiled the Porsche 918 Spyder concept car at the Geneva Motor Show back in March. It was a mid-engined two-seater that combined the performance of a super-sports car with the CO2 emissions of a small compact. Shortly after, Porsche announced plans to build a production version, but they had only 900 customers interested in the car which was about 100 order short of their goal number. This made the decision on sending the Porsche to production a difficult one. However, it seems that the ProConcept voters are still trying to win over consumers to get the orders needed because the German magazine, Auto Motor Und Sport, reported today that Porsche will unveil a pre-production version at the 2011 Nurburgring 24 Hour Race.

Full story after the jump.

The 918 Spyder is powered by a V8 engine delivering more than 500 hp and three electric motors with an overall output of 218hp. The engine emits just 70 grams of CO2 per kilometer and has a fuel consumption of just 3.0 liters/100 kilometers (94 mpg imp). Despite this, the car’s performances are impressive: the sprint from 0 to 60 mph in just under 3.2 seconds, top speed of 198 mph, and a lap time on the Nordschleife of Nürburgring in less than 7:30 minutes, faster than even the Porsche Carrera GT.

Porsche considers the 918 as a successor for the legendary 917 and we will hopefully get to see it zoom out of production soon.
