Dodge Viper speedin' up

This picture has been made during the 24h of Le Mans, edition '15.
Sunday morning, with still some six hours on the clock, I was able to get the Viper in the frame and used a slow shutter speed.
By using this slow shutter speed, the background gets blurry and you get a sense of the speed this car is passing by...
Some extra, imo, the race car is dirty and has some 'battle damage', emphasizing the battle of man and machine against the clock... and the checkered flag.
