A few days ago, we brought you a new series of spy shots for the upcoming Porsche 918 Spyder and today, two new videos have popped up that show the car in action at the famous Nurburgring race track. These two videos may be short, but they do provide a good idea as to how cool the 918's engine sounds.

As a reminder, the 918 Spyder->ke3629 will be powered by a race-derived 4.6-liter V8 engine combined with two electric motors for a total output of 762 HP and 552 lb-ft of torque. The model will be offered with "spectacular solutions such as a full carbon fiber reinforced plastic (CFRP) monocoque with unit carrier, fully adaptive aerodynamics, adaptive rear-axle steering, and the upward-venting 'top pipes' exhaust system." Sales will begin at the end of 2013 at a starting price of $845,000.

Hit the jump for the second video.
