The Mercedes-Benz SLR McLaren Speedster was caught testing once again at the Nuerburgring in Germany, this time by Auto-Motor-und-Sport. We’ve seen the speedster before in another spy video, but the current video not only shows us the car sprinting around the track, but lets us actually hear hear the roar of the monster under the hood. It’s rumored that the top speed is at around 218mph and will be able to go from 0-300km/h (180mph) in 26 seconds. Enjoy.
